Apple has said that they don’t, so maybe you have some reference to back up your claim? The benchmarking section was also given a cursory treatment. Servers (web/database) in general are more I/O bound. Most RISC architectures (SPARC, Power, PowerPC, MIPS) were originally big endian (ARM was little endian), but many (including ARM… Unless you have completely closed your eyes, OSX 10.2 added the GPU as another processor to offload some of its OS duties for GUO in the form of Quartz Extreme. It has very basic design flaws. A CPU with a very high clock speed may not be any faster than a CPU with a lower clock speed. I like wasting my time proving people wrong butI don’t like wasting my time for absolutely nothing. Baseless speculation without evidence nor reference, fanboy yada yada yada: Apple overclocks 1GHz motorola G4s. They are highly efficient, and low power cpu’s. PowerPC (with the backronym Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple–IBM–Motorola alliance, known as AIM.PowerPC… While it may not be quite as quiet as a new Mac, they can be very tolerable. Anyway, I think this article is best viewed as a brief summary (and a pretty decent one), not as proof of any hypothesis or as an argument. History and Architectural Differences The Power5 SMT vs. Pentium4 HT is particularly blatent (though I have no doubt that Power5 SMT will provide more improvement than Pentium4 SMT, I doubt it will double performance and even then it will only improve parallel stuff – much more important for servers than desktops). when you just have one or two, but if I have >20 windows open at a time (and I do), it would absolutely destroy the performance of my system. I’m not sure what this has to do with ILP. It can do really complex instructions entirely using hardware. x86 is still outgunned at the high end and perhaps surprisingly also at the low end – you can’t make an x86 fast and run cool. The current G4 CPUs run at significantly lower speeds compared with the x86 CPUs which are now above 2GHz (P4 > 3GHz). I’ll take your word on the database/transaction stuff. A 2GHz CPU is unlikely to be twice the speed of a 1GHz CPU, indeed on everyday tasks people seem to have some difficulty telling the difference between these speeds. But the Itainium is their concession to the eventual death of the architecture. You may not think heat is important but once you put a number of computers together heat becomes a real problem as does the cost of electricity. ), Simplemente no ha sucedido. The author seems to enjoy making broad statements without providing real proof. Despite not using the highly aggressive methodologies used in the x86 CPUs, IBM have managed to match and even exceed the computing power of x86 CPUs with the PowerPC 970 – at lower power consumption. Great article, easy for even the lay person to understand the gist of it and feel intellectually satisfied. The current desktop PowerPC and x86 CPUs are the following: PowerPC How much do you want him to cover in a short article. The 970 has a long pipeline however it is not run at a very high clock rate, unusually the CPU does more per clock than other long pipeline designs so the 970 is expected to perform very well. Sounds like a good reason not to buy a Mac. The Power5 SMT vs. Pentium4 HT is particularly blatent (though I have no doubt that Power5 SMT will provide more improvement than Pentium4 SMT, I doubt it will double performance and even then it will only improve parallel stuff – much more important for servers than desktops). Vector Processing Differences [13]* Article on G5 benchmarks And, congrats to the OSnews eidtorial staff to have the courage to publish it. I was disappointed with the Pentium 4 and still am because I felt that Intel sold themselves to the marketing side. I'm running Alpha, UltraSPARC (sparc64) and ARM … ARM was the most popular, and Zipf's law took hold. In fact, the most likely way that you’ll see 64 bit x86 adoption is if it comes from Apple in the form of OS X ported for AMD. Vector processing is also known as SIMD (Single Instruction Multiple Data) and it is used in some types of processing. In addition, since the Altivec unit is truly orthogonal, Shadows and Pattern fills along with 6 other desktop drawing functions are being handled by the vector unit while the rest of the processor core was free to do what it needed. RISC vendors will always be able to make a faster, smaller CPUs. You can get a quiet heat sink and power supply for that Athlon. This was added in the G4 CPUs but not to the G3s but these are now expected to get Altivec in a later revision. They transistioned to micro-coded architecture with everyone else in the 80’s. But the architecture was not improved by it. Intel in fact have taken to using a much lower frequency part for laptop computers than the top end Pentium 4. That doesn’t not mean that he is totally wrong. Paul DeMone explains this much better than I can here: http://www.realworldtech.com/page.cfm?articleid=RWT021300000000. GCC 3.2 for instance produced incorrect code for some PowerPC applications. What a great article–truly an exemplar for other submitters! It used a crap ton of very simple cores, instead of the 6 or 8 more powerful cores (plus PPU) in the Cell B.E. Process technology and price are important when you talk about the desktop market. “The Intel 8086, a new microcomputer, extends the midrange 8080 family into the 16-bit arena.”. Not because of technological issues (though there are some of those), but mostly business and market issues. Con el anuncio durante esta semana de los primeros Apple Macintosh basados en procesadores con ISA ARM, después de haber anunciado la transición por parte de Apple hace unos meses, el tema ARM vs x86 ha aparecido y la pregunta de porque no hay CPUs con ISA x86 en dispositivos de bajo consumo ha vuelto a aparecer. The nearest equivalent is the 486 launched way back in 1989. PowerPC was around in Macs for about 12 years. Anyone who looks at PowerPC vs. x86 architectures will come to the conclusion that the RISC vs. CISC argument is a dead one. Difference Between ARM vs X86. I can’t recall the original, 8080 names right now. so too would i expect ia64 to best ppc, since its again a new clean design with no cruft, postdating ppc. It seems however that cutting power consumption in the x86 also means cutting performance – sometimes drastically. Many people still buy a Celeron mainly for the higher clockrate (instead of performance). It is this computer which lead to todays PCs which are still compatible with the 8086 instruction set from 1978. There have of course always been people who can use as much power as they can get their hands on but their numbers are small and getting smaller. Sadly consumers aren’t well informed about the MHz myth despite Apple’s efforts. Changing the programmer can also have a very large effect [5]. And there are devices that do not follow the pattern, like some x86 smartphones. It would be great if this summer AMD was ruled the winner and the entire PC market adapted x86-64, and Intel licensed it, and there was no more war or world hunger, and dogs and cats could live together in peace; but I just don’t see that happening. I believe there is a great potential future for the PPC platform. First off, macOS has to support only two architectures: ARM 64-bit and x86 … x86-64). The P4 really does seem more market driven than engineering driven. I have worked at both x86 & ARM -based hardware shops, although my main work is in GPUs. However the x86 floating point unit is notoriously weak and SSE is now used for floating point operations. (Decoders are so cheap, that they don't even consume an entire cycle; they're normally a combinatorial pre-phase during resource fetch & pipeline dispatch, even for x86.). That’s life, and it may as well be dealt with. B,C,D,E,H and L are register names used in Z80 version of the 8080 asm. I always thought it was a desktop processor. In this rendition. “That said I note that not many have commented on or downright missed the main point of the article – that CISC processors are NOT the same as RISC, and unless Intel or AMD or someone else comes up with a *very* clever design they never will be. To those telling us that it’s full of basic errors please be aware that this is not meant to be a technical reference manual, it’s an article for OSNews. It can easily be done – it’s just that most white box builders don’t bother, which is indeed crap! RISC Vs CISC In the mid 1990s a company called NextGen produced an x86 CPU which used a translator to convert x86 instructions to run within a RISC core. Since AMD is in a world of trouble on … It could of course be done in parallel, guess where the instructions might be and get all possibilities, once the first is decoded you pick the right one and drop the incorrect ones. http://www.cpuscorecard.com/, [7] C3 V’s Celeron benchmarks For example, I don’t understand how you can say that G4 is purely RISC with SIMD units, as it is rather a heavy “unit” in CPU ? SMT thrives on ILP and P4 greatly lacks ILP. Kudos! But, you are starting to restore my trust that there are still those out there who are willing to do some research before writing an article. In a modern x86 CPU this has to be decoded into simpler instructions which can be executed faster. Most people simply don’t undestand that a 50 MHz 68030 isn’t twice as fast as a 25 MHz 68040, but that it’s rather the other way around. If you have an Android mobile device or an AppleiPhone or iPad, there's a good chance it is running on an ARM SoC (system on chip). As the clock speeds goes upwards the actual performance of the CPU does not scale exactly with the clock speed. x86 Processors on the other hand can massively out perform ARM both on single tasks and multiple tasks. There are changes afoot and these could have an unpredictable effect on the market: 1) Corporate adoption of Linux x86 CPUs already get hot and require considerable cooling but this is getting worse and eventually it will hit a wall. Because really, even if I am not a CPU specialist myself, in all technical articles I have ever read ( ars technica, etc… A good site, French only : http://www.onversity.com/cgi-bin/progdepa/default.cgi?Eudo=bgteob&N… ), it’s said that the debate RISC against CISC is dead. The Power5 SMT vs. Pentium4 HT is particularly blatent (though I have no doubt that Power5 SMT will provide more improvement than Pentium4 SMT, I doubt it will double performance and even then it will only improve parallel stuff – much more important for servers than desktops). In the description of the SPEC CPU2000 benchmarks the following is stated: It is like trying to decide what is the best engine design for any application. However RISC vendors are now becoming aware of this threat and are responding by making faster CPUs. What this has done is move all CPU Architecture off their polar position an began rationalizing their ISA to better meet the needs of software evolution to pretty stable foundation based on common C/C++ based Multithreaded, multi-user, operating system to almost a homogenization of feature (Core CPU Instruction, Floating Point Instruction(SP, DP, Parried Single) Debugging Instruction, DSP Like Instructions (Multiply Accumulate, etc), and Vector Instruction the need to better support the market segments and application where they were moving to support. Excellent article, this is what osnews needs, not the blaring fanatical opinions of ogres and trolls, just simple, factual text. I guess that’s where the alpha and epic architectures fall in. I’ve heard(or not heard) several Dells that I could barely tell if they were on or off. Alphas are very power hungry due to their clock tree which is a mesh with a very high capacitance. Not to say that increased resource sharing that SMT allows wills not be goot, but the 100% speedup (or more) that is possiable with SMT in certain applications will not be achieved. Anyway thanks to Nicholas for his IMO well researched article. I also had the privilege of working on the S/38 which eventually became the AS/400 and I marvelled as IBM converted it over to the Power platform. I might "hate" x86 only if I have to program it in assembly (it rarely happens), or if I have to implement it in FPGA ( in this case I will refuse to do it, there is too much complexity), otherwise (for the user point of view) Linux on x86 is exactly equal to Linux to { PowerPC, POWER9, HPPA, MIPS, Alpha, SuperHitachi, SPARC, ARM… Factually, you seem to understand x86 about as well as Hannibal over at Ars understands PPC so this might make a good companion piece but again I can’t tell because of the frustration at de-skewing the apostrophe catastrophe — whaaaa! x86 execution cores use the same techniques as RISC CPUs but the limited number of registers will prove problematic. In addition to the new architecture the 970 includes dual floating point units and a very high bandwidth bus which matches or exceeds anything in the x86 world, this will boost performance and especially boost the Altivec unit’s capabilities. really was the furthest evolution of RISC. ARM, MIPS and PowerPC have been around for ages, so I'd assume support for them would be better than for RISC-V. This should simplify things a bit and increase performance but the compatibility with the x86 instruction set will still hold back it’s potential performance. They use the same techniques but the cores of x86 CPUs require a great deal more hardware to deal with the complexities of the original instruction set and architecture. Problem is that not all applications are going to be able to achieve that speedup (YMMV) and will have to be recoded (or at least recompiled) for SMT, as it requires the code to be processor aware. Get yourself some Zalman bits for your Athlon (not expensive) and it can be completely silent. Wow, thats news to me. It’s never been faster or smoother and the CPU is even more free to handle the actual Apps. x86 CPUs are still compatible with the large complex x86 Instruction set which started with the 8080 and has been growing ever since. Notably Apple’s software division has invested in exactly these sorts of applications. Hey, I think Moto has been sucking on the gas-pipe regardless of the “facts”, and I am no fanboy of either platform. We use VS or Borland in the Wintel world. Since AMD began competing effectively with Intel in the late 1990s both Intel and AMD have been aggressively developing new faster x86 CPUs. GCC no es un comstackdor x86 … también soporta ARM, MIPS, PowerPC, incluso AVR, y muchas otras architectures. Sounds familiar. These days RISC is more like CISC and CISC is more like RISC, we confuse the too a lot. Where did you find out that the P4 lacks ILP? Bottom line – The x86 is like an old 60’s muscle car. Why the heavy-handed treatment of the author by some here? The x86 family of CPUs began life in 1978 as the 8086, an extension to the 8 bit 8080 CPU. The trouble with Quartz Extreme, which I was wishing to highlight, is simply that rendering basic 2D forms in a windowing environment is a minor task to a modern processor. Big Issue today all of these innovations drive Gate Count and chip complexity which reduce our ability to make bigger innovation beyond wait for the next process geometry, When compare and contrast the PIV and the 970 they both do something similar. The x86 architecture as well as several 8-bit architectures are little endian. According to this comment [12] by an ICC user the auto-vectorising for the most part doesn’t make any difference as most code cannot be auto-vectorised. The current (non G5) PowerPC CPUs do not match up to the level of the top x86 CPUs however due to the effects of the law of diminishing returns they are not massively behind in terms of CPU power. All conventional processors are moving towards the “heat wall”. It has been announced in Apple Power Macintosh computers for August 2003, with the pent up demand I think we can expect Mac sales to increase significantly. In the following year the 8088 was introduced which was used in the original IBM PC. The way I see it the categories of comparison look like this. No one uses ICC anyway unless your an intel engineer or obscure developer. If there were such drasic differances, then it would be my guess that Itel missed the mark. They are neither binary nor source compatible. So if you have to fpu that can do double percision multadd you get 4 flops per clock. more like signal to noise AND distortion…:), http://www.igeek.com/articles/Hardware/Processors/, http://www.cs.washington.edu/research/smt/, http://www.onversity.com/cgi-bin/progdepa/default.cgi?Eudo=bgteob&N, Extremist Linux Advocates Doing More Harm Than Good, Google wants to reinvent transportation, Apple sells headphones, Poll: Vote for your Favorite File Manager, Red Hat ES 3.0 vs. SuSE Server 8.0: Battle for the Enterprise, Screenshot Comparison: Outlook, Evolution, Kontact, [Updated with response from Apple] Macs are a privacy nightmare, Working from home at 25MHz: You could do worse than a Quadra 700. Compared to that, a Linux-only user wouldn't really care whenever he is using x86 or a PowerPC like the Talos II, or ARM… My understanding of SMT is that it basically allows a single core to execute multiple threads at once and share a pool of execution units. Way I look at is it really argument of what instruction set you like to program in: ARM, MIPS ALPHA Sparc, PPC, or X86. Apple overclocks them. “nd no realworldtech is not “just a step above marketing”. In fact, OpenGL effectively offloads a degree of that to the GPU to start with, which is why the graphics card needs memory for more than just a look-up table, as opposed to simply streaming a framebuffer out to the screen. First off, HT (Hyper Threading) is a form of SMT (Simultaneous MultiThreading), so stop all this nonsense of HT vs SMT! http://meseec.ce.rit.edu/eecc722-fall2002/722-9-16-2002.pdf. Loading... Unsubscribe from kwegibu? It would be great if this summer AMD was ruled the winner and the entire PC market adapted x86-64, and Intel licensed it. The G5’s however, are a whole new ballgame, and the competition is good for everyone. At the end of the day, both cores cannot be compared in terms of technology node because their implementation depends on a third party. The primary difference between the two major processors is that ARM utilizes smaller silicon space and lower power, conserving energy for longer battery life. One very big difference between PowerPC and x86 is in the area of power consumption. Sounds like a good reason not to buy a Mac. ASoCS: An Architecture Concept for Self-optimizing Parallel and Distributed Computer Systems. http://www.spec.org/cpu2000/results/, [3] Amdahl’s Law Simplified – Richard Wiggins About the Author: Just FYI. I expect I did make the odd error or explain things not quite perfectly but if I am making glaring errors please tell us where they are. Having used both the Itanium and the Alpha versions it become pretty clear that it is a x86 os with ports that less then optomized and stable. x86 benchmarks very well but benchmarks can and are twisted to the advantage of the manufacturer. HP and SGI may have given up but IBM has POWER5 and POWER6 on the way and Sun is set to launch CPUs which handle up to 32 threads. The industry’s dependence on x86 processors appeared to … See if you can read the following 8080 code (CP/M operating system manual, 1982 edition, page 212-213, lines 186-199). Consequently keeping the size of software down was important and the instruction sets in CPUs at the time reflected this. It is so cool! IBM 750xx (G3) I’m running an Athlon 2400+ system with no case fans, and it runs stable and cool with virtually zero noise. Most of these subtle differences lie in the way memory is addressed, exceptions are handled, branches are executed etc. This was a set of artificial benchmarks but does this translate into real life speed improvements? The x86 CPUs on the other hand have very high power consumption due to the old, inefficient architecture as well as all the techniques used to raise the performance and clock speed. This was the time when x86 became the only option for the masses to use and develop all their software on. Given the above, one might wonder why Q can be based on a microkernel (strictly speaking it’s only “microkernel like”) and still expected to perform well. El gran problema, por supuesto, es que no hay Windows. The 8086 was just an 8088 with a 16 bit data bus. Too bad it is now a dead end design. The disadvantage is that this architecture accumulated many features that are no longer really useful and can be quite burdensome in optimizing the design for performance and power usage. First, leakage current is higher and second, you have to overload the base of the transistor by using higher voltage for make it switch faster (oversaturation). Performance Differences Between The PowerPC And x86 I wonder what his conclusions will be….hmmm.. Now the world may end, Bouma and I actually agreed on something. So they had two choice Fast Clock speed Narrow Super-pipelined architecture or wide slower clock high CPI Micro architectures. There is plenty of low cost hardware and tons of software to run on it, the same cannot be said for any other CPU architecture. Do not get me wrong – Intel has done a wonderful job at keeping the platform going – I have been declaring it dead since the 80286 came out. ILoveWindows: Without using SSE or Altivec, you are really going against the abilities of modern processors, and the results you get are not meaningful. In the meantime, Intel left the market wide open for IBM and their 970 processor is just amazing, it truly is one of the most exciting developments I have seen for some time in the desktop world. Anyone who looks at PowerPC vs. x86 architectures will come to the conclusion that the RISC vs. CISC argument is a dead one. There are certainly cases where SMT will provide large performance increases, but we aren’t talking about a 100% improvement in most cases. Some think of the PPC as only a Mac but IBM has been selling top of the line professional mission critical machines based on the PPC platform for many years. These use a simplified instruction set which allow the CPUs to be simpler and thus faster. Honestly…. The Law Of Diminishing Returns (Aka Amdahl’s Law) If you want to see innovation in CPU architecture look at following project since they are truly driving innovation into again CPU design, Compiler Research and Operating Systems and Application Design To MIT projects are based on MIPS like instruction set. PowerPCs although initially designed as desktop processors are primarily used in embedded applications where power usage concerns outweigh raw processing power. By the way my OS X is automatically spell checking everything I type in this form and actually allows me to context switch to the right spelling. The amount of voltage the CPU can use restricts the power available and this effects the speed the clock can run at, x86 CPUs use relatively high voltages to allow higher clock rates, to boost clock speeds further, power hungry high speed transistors are used. Benchmarks If so the instructions per cycle increases and the CPU gets it’s work done faster. but saying that it was the first generation (EV4). PPC will never see a significant lead over x86 due simply to economies of scale. What I mean is that this is the frist time I have read something that explained the differnces in a way that made some sence to me. The PowerPC family began life with the PowerPC 601 in 1993, the result of a collaboration started in 1991 between Apple, IBM and Motorola. IBM have already managed to get this processor to run at 2.5GHz and this should perform better than any x86 (with the possible exception of the Opteron). They may be about the same speed, but the PPC has a lot more room to grow. It was a big move by Apple to switch from IBM-built PowerPC processors to x86 processors made by Intel. This strategy looks set to continue in the next generation POWER5. At that time, many questioned Apple’s motive behind the transition. The latter don’t know much detail about processor design. By executing the full set of 8080A/8085 8-bit instructions plus a powerful new set of 16-bit instructions, it enables a system designer familiar with existing 8080 devices to boost performance by a factor of as much as 10 while using essentially the same 8080 software package and development tools. You don't want to constantly recharge batteries or pay more for electricit… But so are the artificial benchmarks. I won’t argue that offloading processing onto the GPU is a bad thing, because it isn’t, but that is only worthwhile if you intend to use some serious vector-based tasks on such a system. Later, in 2006, Apple decided to replace their PowerPC based processors in Macintosh computers with Intel chips, too. This article is concerned with the technical differences between the families not the market differences. RISC was originally developed at IBM by John Cocke in 1974 [1]. I bought a 1984 Mac and marveled at the 68000 processor. Because of the sheer complexity of the x86 ISA and it’s limited number of architectural registers a RISC processor requires less hardware to do the same work. The original describes the problem in parallel computing terms however this simplified version pretty much describes the problem in terms of any modern computer system: “Each component of a computer system contributes delay to the system This place is always going to be a war zone in the comments, but your article was fair, balanced, and quite accurate. He seems to start with a conclusion and then look for ways of justifying it. The figures Apple gave for the Dell PC were a great deal lower than the figures presented on the SPEC website. Thinking about the x86 strategy in terms of marketing is a pure wonder–however, if Intel had actually focused on creating a better architecture rather than one that had many parameters to tweak such as mhz, cache size, bus speed, hyperthreading, etc where some marketing guru could overstate again and again, where would we be today? Also there are some devices that use PowerPC, like PS3. I would argue these Microcodes made Intel more RISC then the current classic ISA level RISC processor. The move to Arm marks Apple's biggest shift since it moved from PowerPC to Intel's x86 processors fifteen long years ago and ... wont survive in a arm vs x86 war. The obvious answer: All are critical for good performance, and a deficiency in any can bring down the whole system. RISC = Reduced Instruction Set Computer) is a compact and energy saving, not a high performance chipset. Most especially, if you look at the P4, the classic FP performance is very weak, while using SSE literally will double performance in many cases. The idea was to have parallel processing power without the cost of a single multi-core chip. because it was making my head hurt. Dude — an apostrophe does not mean “watch out, here comes an ‘s’ ! They had to look at innovative way to deal with memory latencies (Caches, Larger Register Sets, Instruction Buffer, etc) , also understand how best to deal to code control flow issue ( branch prediction) Here is were the visionaries evolved and ALPHA was one of the greatest CPU experimenting environments to emerge in the last 10 years and they tried all the variation ( In-order, Out of Order, Dual Issue, Multi issue, Multithreading, on chip memory controllers and more). Additionally the latency of memory has barely improved at all so any program which requires the CPU to access memory a lot will be effected badly by memory latency and the CPU will not reach anything near it’s true potential. The article was okay, but still somewhat biased, especially in concluding that RISC processors have always been faster. There has been a great deal of controversy over the benchmarks that Apple has published when it announced the new PPC 970 based G5 [10]. If you work the numbers on the Pentium 4, you’ll find that the percentage of time its execution units sit idle is approximately equal to the percentage of branch instructions in the code it is executing. I never meant web-servers, but it looks like SMT/HT helps more for heavy computation tasks (scientific, multimedia editing, games possibly someday). I think it’s fairly safe to assume this at least in part is the reason for the difference between the SPEC scores produced by Apple and Intel. He works for Genesi who produce the Pegasos G3 / G4 PowerPC based motherboard and the MorphOS Operating System. The PowerPC Linux laptop is not going to appear overnight. The Figure given for the design rating of a P4 3GHz is 81.9 Watts so the maximum is closer to and may even exceed 100 Watts. Once they get a die shrink into the next process generation power consumption for the existing performance will go down. — x86 is controlled (essentially) by Intel, AMD, and Via(? I don't know anything about PowerPC, but I can tell you some of the differences between x86 and ARM. VIA have managed to get power usage down even at 1GHz levels but they too use a different architecture. The Itanium is also a big disappointment, and it appears that Opteron and Athlon 64 will once again get more attention that Intel. The best G4 motorola produces is 1GHz. I gave up commenting on those a long time ago because although there are good and bad points to both platforms – and of course personal opinions – there were a lot of people who obviously couldn’t see this and attempting to debate sensibly is a futile exercise.
