Privacy Policy “These benchmarks measure the performance of the processor, memory and compiler on the tested system.”. Moore’s Law describes how things are getting better, Amdahl’s Law says why it’s not. Let me suggest looking two words up in the dictionary: effect and affect. By using GCC Apple removed the compiler from the factors effecting system speed and gave a more direct CPU to CPU comparison. It just matter of a lot of money, 18 to 48 month of time, getting good experienced CPU micro-architects and Quantum Mechanics (Transistor Tweekers). Dude — an apostrophe does not mean “watch out, here comes an ‘s’ ! The history of the PowerPC begins with IBM's 801 prototype chip of John Cocke's RISC ideas in the late 1970s. Honestly…. However the x86 floating point unit is notoriously weak and SSE is now used for floating point operations. Intel however can make many more CPUs for less. Decoding the x86 instruction set is not going to be a simple operation, especially if you want to do it fast. ICC is picking up the code and auto-vectorising it for the x86 SSE2 unit, the other compilers do not have this feature so don’t get it’s benefit. The POWER5 (of which there will be a “consumer version”) will include Simultaneous Multi-Threading which effectively doubles the performance of the processor unlike Intel’s Hyper Threading which only boosted the performance by 20% (although this looks set to improve). 8080: Flat 16 bit addressing with 8 bit GP registers. And Quartz extreme does. Not because of technological issues (though there are some of those), but mostly business and market issues. 3) No more need for speed The longer pipelines allow the x86 CPUs to attain these very high frequencies whereas the PowerPCs G4s are somewhat restricted because they use a smaller number of pipeline stages and this limits the clock frequency. The Pentium 4 is now at 3.2 GHz yet a 1.25 GHz Alpha can easily outgun it on floating point operations. This architecture is also highly sensitive to the compiler and this author has read (on more than one occasion) from Itanium users that it’s performance is not what the benchmarks suggest. Just that the way it is executed will have to change. Intel has also invested in compiler technology which automatically uses the SSE2 unit even if the programmer hasn’t specified it boosting performance. There seems to be two types of people here, the electrical engineer/computer engineer type, and the GUI/widgets/font/web designer type. What about Pipelining, any ideas on that one? A Phoronix reader has provided comparison benchmarks of his PowerMac G5 to our recent Intel Kabylake CPU benchmarks and other recent x86 CPU tests. The Opteron is designed as a server CPU and as such both the CPU and motherboards cost more than for normal desktop x86 CPUs. i don’t think one person can possibly keep up on moderation chores on the miserable lot of you. The level of discourse on these boards has gone to hell. This wasn’t un-optimized code, and if they had utilitzed alvitec and SSE, most likely the results would have been even more dispartate. I’ve mainly heard of ILP in relation to Intel’s EPIC architecture. Now, with the release of Panther, Apple has added Windowing and scrolling to Quartz Extreme as well. And no realworldtech is not “just a step above marketing”. He hit on the salient points, we all understood what he meant. VMware to support paravirtualised Linux systems in ...

IBM 970 (G5). So much of how well a computer works depends on the task and the parts surrounding the cpu and the tools to do the work. An x86 will need hardware assist just to perform a single iteration. A second grader writes with better grammar. Bob: 4004 and 8086 are not related (except in the lame MS joke that ends with “… 1 bit of competition”) either. The PPC platform is so far different that this is a useless discussion. Likewise, even though it’s not directly OS-related, such an article is representative of what I’d like to see more often at OSnews instead of the non-informative, highly opinionated, unresearched drivel we unfortunately seem to get so much of. An OSnews comment is hardly an authoritative source. This email address is already registered. You might have no problem watching your windows shrink, spin, etc. Nicholas writes that Intel uses high speed transistors which consume more power. I’m running an Athlon 2400+ system with no case fans, and it runs stable and cool with virtually zero noise. One Comment, 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. I don’t know well realwordtech, but ars technica is really a good reference, even if it is a bit PC biased. Thanks for the informative article. 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. You have exceeded the maximum character limit. “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. The other x86 server/workstation systems I had locally for comparison to these initial POWER9 benchmark numbers were: 2 x Intel Xeon Gold 6138 - The Tyan S7106 1U barebones with two Xeon Gold 6138 processors yielding a combined 40 cores / 80 threads, 96GB of RAM, and Samsung 850 EVO 256GB. Legacy Desktops, legacy servers, current notebooks: Pentium III vs. G3 vs. P4 vs. PM vs. Athlon vs. Xeon vs. Athlon MP. instead of insults, could you provide pointers contradicting the article, and specifically that grave mistake you’ve noticed ? It would seem that threads that don’t fully utilize the execution units would benefit most from SMT. In theory, x86 … The POWER4 and PPC 970 also do this with some instructions but this is a relatively simple process compared with the multi-length instructions or the complex addressing modes found in the x86 instruction set. No need to convert CISC -> RISC ISA Altivec is also present in the 970. Paul DeMone explains this much better than I can here: http://www.realworldtech.com/page.cfm?articleid=RWT021300000000. Nicholas Blachford has been interested in CPUs for many years and has written on the subject for OSNews before. If you don’t know shit about different CPU architectures, why POST about them? High End Desktop/Workstations/SMB Servers: Athlon 64 vs 970 (G5) vs ? (http://www.cs.washington.edu/research/smt/), On the power issue of X86 core look know further then the Pentium M which is one incredible X86 CPU which matches PPC G4 10 Watts 1 GHz with and the bonus of an amazing branch prediction unit, and 1 megabyte of onboard L2 Cache. After having finishing the article, it does seem to miss some points, but still overall, the article is good and one of the better reads I’ve had on Osnews in a long, long time. One very big difference between PowerPC and x86 is in the area of power consumption. This is a generational shift and right now only the Athlon 64 and 970 are in play for the next generation desktop. Also at the end of your article you predict (as many others have in the past) that Intel will hit the ‘heat wall’ and that the future looks bright for RISC technologies but BAD for CISC. Oh, how the mighty have fallen. I’ve heard of power supplies with a 28 dB rating, which is VERY quiet. PowerPC is sold both as silicon (i.e. its all about the x86. 2) Market saturation 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.
