This does not invalidate the ICC SPEC FP results or justify Apple’s use of GCC. Don’t get me wrong; I hope I’m wrong for the PC markets sake. So if you have to fpu that can do double percision multadd you get 4 flops per clock. This lets the ARM … 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). 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. I’m not surprised really that Intel’s ICC compiler vectorizes Spec’s FP intended instructions. * Article on G5 benchmarks 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. 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… 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? The x86 can never be designed for a mission critical task. If their was a best for “any” it surely would not be the best for each specific application. Many of the techniques used within x86 CPUs may only boost performance by a small amount but they are used because of the need for AMD and Intel to outdo one another. x86 is designed to be very fast. IBM are also adding hardware acceleration of common functions such as communications and virtual memory acceleration onto the CPU. It was a big move by Apple to switch from IBM-built PowerPC processors to x86 processors made by Intel. If you don’t know shit about different CPU architectures, why do you feel need to write about them? The x86 is bigger requires twice the clock speed, generates 4 times the heat do do the same amount of work as the PPC. 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. Once you have the instructions in simpler “RISC like” format they should run just as fast – or should they? We all know that the Pentium 4 was a bad deal compared to the Pentium III till it broke 2Ghz, AMD taught Intel a lesson for that blunder and took a major chunk of their marketshare with what now is the Athlon. Feel free to draw a different conclusion from these facts. However, that doesn’t mean that x86 code can not scale to higher and higher speeds. The author seems to enjoy making broad statements without providing real proof. Both families are in the process of transitioning to 64 bit. I’ve always looked at the Macs and admired their clean solutions, and now I simply must own one…. RISC CPUs are a great deal more efficient. http://www.cpuscorecard.com/,  C3 V’s Celeron benchmarks MCU) as well as synthesizable IP blocks; Arm only sells IP, but there are a number of companies that sell microcontrollers built around said IP. If they had left it in the ppc 970 would have been the Flop lead above the power 4 and everyone else. While I have had an interest in CPUs for quite some time but I have never explored this issue in any detail so writing the document proved an interesting exercise. Kudos! For all of RISCs ‘advantages’ (many of which you state in this article) CISC still seems to come out on top. The Hardware assist in question is Out-Of-Order execution and the tools of this trade are called rename registers. Materiales de aprendizaje gratuitos. http://www.realworldtech.com/page.cfm?ArticleID=RWT060503232439, Further Reading Where did you find out that the P4 lacks ILP? The clock speed of the CPU is limited by the time an individual stage needs to complete. Things are changing, Linux and other Operating Systems are becoming increasingly popular and these are not locked into x86 or any other platform. Dude — an apostrophe does not mean “watch out, here comes an ‘s’ ! 8086 is way more complicated than 8080 with 16 bit additions (8080 can use 16 bit adressing with BC, DE or HL register couples, btw.). Facts: CISC vs. RISC doesn’t matter. The PowerPC 970 is as predicted on OSNews  is a 64 bit PowerPC CPU based on the IBM POWER 4 design but with a smaller cache and the addition of the Altivec unit as found in the G4. An x86 will need hardware assist just to perform a single iteration. 4) Heat problems The design is currently also making strides in notebooks and other devices where improved energy efficiency is in demand. phew…. Your Quartz Extreme observations are wrong, offloading more and more processing to the GPU is state of the art in computer science circles and much research is being done on it at the university level. Just check the decibel rating for something below 40 dB, below 30 if you can. I always thought it was a desktop processor. There is already some support for this CPU in linux and the BSDs, a 64 bit version of Windows is also due. (2) the P4 is clocked 3 times higher than the G4, have a higher bandwidth interconnection and have more cache. x86 is a term meaning any instruction set which derived from the instruction set of Intel 8086 … The PPC is a 1990’s architecture that is near the beginning of it’s life. i don’t think one person can possibly keep up on moderation chores on the miserable lot of you. Commercial RISC microprocessors appeared in the mid 80s first in workstations later moving to the desktop in the Acorn Archimedes. 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… Are you kidding mate? Apple promised at the 2002 WWDC that they have only begun to exploit the GPU for the OS and they are showing even more work in Panther. However, it seems to me that at some point x86 is going to have to have liquid-cooling to keep their processors cool enough. A second grader writes with better grammar. 8080: Flat 16 bit addressing with 8 bit GP registers. I have no problems with AMD, and I like their x86-64 implementation. A personal note: I come here a lot less these days. The Law Of Diminishing Returns (Aka Amdahl’s Law) Mr. Blachford attempts to speak with authority, yet he just doesn’t seem credible, especailly compared to all the better sources out there. He seems blatantly biased towards the G3-G5 cpu’s, but just because he’s biased doesn’t mean he’s wrong. That is not to mention that due to the architectures of the P4 vs. the 970, they will perform differently depending on the detailed formation of the code, such as the sizes of matrices, fp precision required, formation of loops/conditions and a whole host of other factors. However, this does lead to the question of why the SPEC scores produced by GCC are so different from those produced by Intel’s ICC compiler which it uses when submitting SPEC results. Legacy Desktops, legacy servers, current notebooks: Pentium III vs. G3 vs. P4 vs. PM vs. Athlon vs. Xeon vs. Athlon MP. x86 execution cores use the same techniques as RISC CPUs but the limited number of registers will prove problematic. Alongside this it is also worth highlighting that an x86 CPU can do anything an ARM can do. Probably should have gotten IBM to have ported all the compilers to OSX at the same time. However when the x86 includes this kind of hardware the 8 registers becomes a problem. This article is concerned with the technical differences between the families not the market differences. The x86 architecture as well as several 8-bit architectures are little endian. Perhaps it would have been better if it where a comparison of the two architectures and not a drift off into a poorly formated discussion of many chip architectures. I’m running an Athlon 2400+ system with no case fans, and it runs stable and cool with virtually zero noise. 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. ARM processors, however, are getting faster, and more developers are writing programs for the architecture. 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. No matter which way you look at it, you are creating extra system load and the idea of having an independent framebuffer per window in memory is insane and has predictable results. If you want to know why ARM is in all the smart-phones? Ultimately, you will always find that the PPC architecture will perform around 70-95% of current x86 architecture in the consumer market and this will remain the case, simply because processor design is admittedly complex and we’ve not seen massively revelatory new designs in recent years. I have to agree that this guy doesn’t really know what he is talking about. However, since its 2016, and we can fit, say, 128 decoders in less area than the L0 backing store of a many-core machine, decode is only interesting in terms of how well the instructions can be compressed. However the x86 floating point unit is notoriously weak and SSE is now used for floating point operations. But Apple chose not to use its Veclib in the Spec test. Back in my day, if you wanted top notch CPU performance, you had to go with a high-end x86 chip, or, if you had deeper pockets, you could get something exotic, like a PowerPC system. What Linux has been doing is defragmenting the hardware vendors. There are no doubt real life areas where the auto-vectorisation works but if these are only a small minority of applications, benchmarks that are effected by it become rather meaningless since they do show reliably how most applications are likely to perform. What’s the point of upgrading your computer if you’re not going to notice any difference? Again IBM would not like that. Many of you talk about CISC pulling ahead of RISC, but many of you forget that Intel had to basically make their processors RISC-like to compete. well actually this article tells the reader, little if anything about the PPC. All the good bits in our app, the 3D engines, etc, are made up of identical code that is simply recompiled on the various platforms and linked with the appropriate toolkit. It is just a fact that an x86 … In particular I’d like to know more about the less-common processors, and their operating systems and software. He works for Genesi who produce the Pegasos G3 / G4 PowerPC based motherboard and the MorphOS Operating System. Too bad it is now a dead end design. Sounds familiar. To put it simply, you don’t need your windows to warp, spin, etc. And hey, Nicholas, that is one of the better, factual, non-troll articles that have been here in a while. its all about the x86. Apple’s Rosetta 2 vs Windows x86 Emulation: Translation Performance. Well at least for a fair number of years the PowerPC CPU in mac actually outperformed x86 pretty well, but as time wen on x86 cought up and surpassed PowerPC. Windows and COM+ are not very well threaded. While i liked the article, and i’m a die-hard anti-x86 guy, I have problems taking the article as a whole very seriously. But in the current CPU market, ARM is the dominant non-Intel based CPU and the PowerPC is fading fast. http://arstechnica.com/cpu/03q1/ppc970/ppc970-0.html. because it was making my head hurt. Altivec is also present in the 970. http://www.cs.utexas.edu/users/cart/trips/, http://www.cag.lcs.mit.edu/scale/overview.html, (don’t worry about it, “goo” doesn’t know what he’s talking about, but you have to give it to him, he talks a good game!!). BTW, before OSX, Apple’s multiprocessor experience pretty much consisted of adding an extra processor to improve Photoshop performance (the second processor was not utilized by most applications). CPUs break down all operations into stages and these are performed in a pipeline, these stages can be big or small and the number of stages depends on what’s done in each stage, the more an individual stage does the less stages you need to complete the operation. Effectively both architectures have reached a point where they rely on a … 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. http://www.aceshardware.com/read_news.jsp?id=75000387,  But  does not appear to continue into real life code IBM probably did not want that… But apple would have gotten a lot of HPTC customers. I am getting old. They are well researched and good reads. In addition to the good points already mentioned, it is important to keep in mind that x86 was used in the original IBM PC, which was very important because it gave rise to lots of clones that had a similar setup to be able to run the same programs. Listen, Megol, I’m not the very best at math, and I certainly don’t want to defend Motorola’s clock speeds, but the fastest G4 right now is 1.42ghz. Intel is also trying to expand its presence in the embedded market with its x86 … Servers (web/database) in general are more I/O bound. You add massive overhead to the system and quickly reduce responsiveness if the thing has to start paging to disk to support your graphical excess. That’s just a fact, it is not meant as a personal insult so get your emotions out of it already. Tras las noticias sucedidas en el ltimo a o, en las que primero Apple se pasaba de procesadores PowerPc a procesadores Intel, despu s se consegu a instalar Mac OS X (para la arquitectura x86) en ordenadores con dicha arquitectura pero que no eran Apple, y finalmente Apple lanzaba la herramienta Boot Camp con la que se permite instalar en sus nuevos "MacIntel" Windows … I am an armchair computer enthusist. I also question how much linux is really cross platfrom. It would be great if this summer AMD was ruled the winner and the entire PC market adapted x86-64, and Intel licensed it. x86 CPUs already get hot and require considerable cooling but this is getting worse and eventually it will hit a wall. 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! PPC can be one of the best computers for any task if so designed to do so. PowerPCs although initially designed as desktop processors are primarily used in embedded applications where power usage concerns outweigh raw processing power. It also does not consider the glue. You still have to shuffle the registers so that all math involves the AX register. Additionally it also shows it’s age by the small number and complex nature of registers (internal stores) available to the programmer. The Law of diminishing returns is not exactly a new phenomenon, it was originally noticed in parallel computers by IBM engineer Gene Amdahl, one of creators of the IBM System 360 Architecture. Man I wish DEC would have gotten a clue and tried to push the Alpha into the consumer arena. This was a set of artificial benchmarks but does this translate into real life speed improvements? I’m sure you also wouldn’t consider a Pentium equivalent to a Ryzen even though they are both x86. Intel was blind-sided by the iPhone revolution, and doesn't (functionally) allow 3rd-party licensing of x86. Effectively both architectures have reached a point where they rely on a RISC core with a translator and interesting caching and processing units to compensate. Also there are some devices that use PowerPC, like PS3. Yes, the Ars articles actually provide content intead of fanboyism. The reason for the lack of scaling is the fact that memory performance has not scaled with the CPU so the CPU is sitting doing nothing for much of it’s time (HP estimate this at 70% for server CPUs). 8). About the Author: “The Intel 8086, a new microcomputer, extends the midrange 8080 family into the 16-bit arena. Linux runs across many different architectures if you need more power or low heat / noise you can run Linux on systems which have those features. When used it speeds up operations many times over the normal processing core. Go to Anandtech, Tom’s Hardware, Ars Technica and other tech sites will show you that on intensive processes such as 3D rendering, for the first half year of P4 release, without SSE2 recompiles of the software, relying on x87 floating point, it got creamed by the Athlon. By the way databases and transaction based systems thrive on multi-threading. This means PowerPC Operating Systems can use a microkernel architecture with all it’s advantages yet without the cost of slow context switches. The massive growth of the computer market is ending as the market is reaching saturation. This was the time when x86 became the only option for the masses to use and develop all their software on. To RISC Or Not To RISC  Escape from planet x86 – Paul DeMone The AMD Opteron adds 64 bit addressing and 64 bit registers to the x86 line. They are also more suitable for rendering, transcoding, graphic creation in VMs and more. the 25MHz 040 was indeed running at 50MHz internally (much like the R4000 for example). It seems however that cutting power consumption in the x86 also means cutting performance – sometimes drastically. Just like many things, the fact that PPC is more efficient doesn’t mean that it is going to be better, or faster, or more wide-spread. One very big difference between PowerPC and x86 is in the area of power consumption. Get yourself some Zalman bits for your Athlon (not expensive) and it can be completely silent. Decoding the x86 instruction set is not going to be a simple operation, especially if you want to do it fast. Undoubtedly, most people remember PowerPC from old Macs. He builds powerpc systems. The obvious answer: All are critical for good performance, and a deficiency in any can bring down the whole system. The x86 instruction set is highly complex with many instructions and addressing modes. A single 3GHz Pentium 4 CPU alone consumes more than 4 times power than a Pegasos PowerPC motherboard including a 1GHz G4. The Pentium 4 has 128 rename registers, the 970 has less than half at 48 and the G4 has just 16. Problem is that they assume that Intel will not change some aspect of their technology. This article isn’t all that it looks to be. History and Architectural Differences The two processors weren’t opcode-compatible, but they were explicitly designed to have one-to-one translations from 8080 to 8086 opcodes so machine code could actually be translated simply, not reassembled. Both Amdahl’s Law (of diminishing returns) and Moore’s Law date from around the same time but notably we hear a great deal more about Moore’s law. The way I see it the categories of comparison look like this. 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. It is a problem with the x86 architecture that causes context switches to be computationally expensive. So now that IBM made this leap in Processor design it now back to race to who the best process technology and do most innovative transistors, with minor micro-architecture tweaks . Would you buy a PowerPC Linux laptop? The x86 line is a 1970’s arcitecture that has been tweaked into the future. At the end of the day, both cores cannot be compared in terms of technology node because their implementation depends on a third party. You can get a quiet heat sink and power supply for that Athlon. So this point is moot as well since this Micro-architecture and Quantum Mechanic issue (Transistor tweeker). Yup, you are probably right. GCC may not be the best x86 compiler but it contains a scheduler for neither the P4 or PPC 970 however it is considerably more mature on x86 than PowerPC. But from what I have seen, the 80486 and 8080 appeared very similar at the assembly level (Sorry, I have not done much intel assembly to have a real feel for it). High End Desktop/Workstations/SMB Servers: Athlon 64 vs 970 (G5) vs ? Yeah, the Alpha rocks. Now after about 14 years everything points at Apples Apple Silicon implementation has cought up and surpassed x86 … You can make the implementation of any of the major 3 either a performance-targeted power-hog, or a power-sipping light-weight. 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. This is why it makes sense to use x86 processors in PCs and ARM processors in phones. That kind of x86 extensions are already covered by an old cross licensing agreement between Intel and AMD. That a 3GHz P4 consumes over 100W (peak) and a 1GHz G4 only consumes ~10W is not relevant as: (1) the G4 is a low power embedded processor and the P4 is a high-end workstation processor. In the high end markets, RISC CPUs from HP, SGI, IBM and Sun still dominate. Vector Unit vs Vector unit Apple wins hands down, so get off justifying ICC’s auto-vectorization. The VIA C3 series is a very simple CPU based on an architecture which forgoes the advanced features like instruction re-ordering and multiple execution units. But the architecture was not improved by it. Nicholas Blachford has been interested in CPUs for many years and has written on the subject for OSNews before. But, the commentary has made my day. That would have helped too. Arm, seems like an appropriate stand-off. By the way, there is no such thing as an unbiased opinion. I do not know if the binary’s were compatible, and I know the mneumonics were extended, but the idea was to be able to use your 8088/8086. 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). IMO, SMT will not speed up servers (file, web, DB, etc) that much. 2) Market saturation 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. And for me, it seems a lot better than realworldtech. Meanwhile, the x86-dependent power base is being nibbled away by increasingly powerful phones and tablets on one side and, if Amazon and co. succeed with their ARM server developments (which mainly consists of trying to educate people that "yes, NGENIX and Node.Js have been on ARM for years"), its going to get nibbled from the other end. Powerpc vs arm. This is a unique advantage of ARM Macs over Intel x86 chips. Great article, easy for even the lay person to understand the gist of it and feel intellectually satisfied. Here some of the best research on the subject. There are more than one or two facts which describe why a processor consumes more or less power. Microsoft and Intel’s domination of the PC world has meant no RISC CPU has ever had success in this market aside from the PowerPCs in Apple systems and their market share is hardly huge. While the new Windows x86 emulation is due to arrive next year, there are some other issues that make x86 translation on Windows much slower than Rosetta. (The original releases of MS-DOS 1.0 actually had a Digital Research copyright string embedded in them because of this.). The old Single accumilator design persists even in the P4. 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. http://www.igeek.com/articles/Hardware/Processors/x86-64vPPC-64.txt. 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. Both x86 and PowerPC have added extensions to support Vector instructions. Anyone know about these? Hardware companies will most likely continue to try to use tricks to mislead benchmarking software and so to artificially produce higher figures or will do everything dispute results when they are not in their favour and further confusing the general public. Otherwise you wouldn’t be able to make such blanket statements such as “the PPC architecture will perform around 70-95% of current x86 architecture” with a straight face, and with some facts behind you, no doubt!!!
