First off, how many of you have heard of PowerPC? 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. Only with .NET has Microsoft started to emphasize delegating of threads and asynchronous programming, but it is a very large framework and will take a couple of more years to mature. 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. Effectively both architectures have reached a point where they rely on a … Lately it seems like Windows fans are worse than Mac fans in their worship! The x86 is an 8 bit arcitecture that has been extended to now, so the A register was extended to 16 bits by renaming the A as AL and adding an AH, then when they went to 32 bits, they attached another 16 bits and call it AX. As I can read PowerPC (e200z2/e200z4/e200z7..) are most widely in use whereas ARM has started picking up recently with its Cortex-R4F series.. Any idea where can I get more information about: - features of an automotive CPU - comparison b/w PowerPC vs ARM for … IBM 970 (G5). ”. I liked what he had to say, and i dont think he made many SERIOUS mistakes, but it was obvious from the beginning that he was going to make this a PPC 0wNz x86 article. Apple’s Rosetta 2 vs Windows x86 Emulation: Translation Performance. Honestly…. Apple has said that they don’t, so maybe you have some reference to back up your claim? Why The Difference? except that identical to CALL), 8086: interrupts are handled via special all-register stack dumping instructions. As for Apple Silicon; Honestly it’s not that much about RISC vs. CISC. 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. Perhaps you need to put the pipe down a bit sooner before writing your next article. First off, HT (Hyper Threading) is a form of SMT (Simultaneous MultiThreading), so stop all this nonsense of HT vs SMT! 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 real comparisons will happen against the Athlon 64. I just finished a 600-level class in computer architecture and that was over my head. 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. I don't know anything about PowerPC, but I can tell you some of the differences between x86 and ARM. Also memory code size limitations of the past are distant memory in the desktop and server space. ARM processors are designed to be efficient in terms of energy usage. http://www.apple.com/powermac/architecture.html. 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, Itanium, ... } yet another Linux box, except that: HyperThreading is a hack designed to utilize execution units of the P4 which sit idle as a tainted trace cache is cleared and its pipeline is repopulated following a mispredicted branch. ARM vs. x86. Both IBM and the Alpha team announced the addition of Multithreading support was expected to give a 100% boost in performance. It does very little good on Processors that have a low degree of parallelism and whose OS’s and their development frameworks do not promote asynchronous processing. The part of the post the author refers to correctly points out that SPEC FP performance is NOT indicative of overall system performance because most applications use mainly integer code. 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. Please, throw out this article and look elsewhere (Ace’s Hardware and ArsTechnica are both VERY good sites for this type of stuff). The computer age as we know it is at an end. 3) No more need for speed If they had left it in the ppc 970 would have been the Flop lead above the power 4 and everyone else. The consequence of this has been that many Operating Systems have switched from their original microkernel roots and become closer to a macrokernel by moving functionality into the kernel, i.e. MIPS vs ARM A number of differences between MIPS and ARM can be identified though both are in the same family of instruction sets. The obvious answer: All are critical for good performance, and a deficiency in any can bring down the whole system. When used it speeds up operations many times over the normal processing core. This was a set of artificial benchmarks but does this translate into real life speed improvements? In the high end markets, RISC CPUs from HP, SGI, IBM and Sun still dominate. Just FYI. When HT arrived it gave only 20% – 30%, I believe it is to be enhanced soon. 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. This means PowerPC Operating Systems can use a microkernel architecture with all it’s advantages yet without the cost of slow context switches. Or even the instruction set, really. However if the stages are simple you will need more of them but each stage can complete quicker. Can you say proofreading? RISC = Reduced Instruction Set Computer) is a compact and energy saving, not a high performance chipset. The x86 is bigger requires twice the clock speed, generates 4 times the heat do do the same amount of work as the PPC. (Technology is much more clean and pure than politics and business markets). When smartphones were introduced, there was no reason to run the old programs so it made sense to use a cleaner design (ARM) instead. AMD seems to want to keep it alive by broviding for effiecent operation of 32 bit code. AMD’s system architecture (outside the processor) is very cool. I’m a technology guy, I wish the technology was all there was. That’s what bothers me a bit. 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. 4004 has no architectural descendants. That is its main purpose. 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. Like I said in my original statement…, “though I have no doubt that Power5 SMT will provide more improvement than Pentium4 SMT”. In the description of the SPEC CPU2000 benchmarks the following is stated: PPC will never see a significant lead over x86 due simply to economies of scale. You can make the implementation of any of the major 3 either a performance-targeted power-hog, or a power-sipping light-weight. Conclusion There is a lot of marketing goes into x86 and the market -technical people included- just lap it up. The current desktop PowerPC and x86 CPUs are the following: PowerPC 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. Longhorn is daft in trying to do that as well. 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. Computers are now so fast it’s getting difficult to tell the difference between CPUs even if their clock speeds are a GHz apart. Just check the decibel rating for something below 40 dB, below 30 if you can. …this is utterly a pointless argument, since it’s coming down to different interpretations of what Intel’s 1979 press release meant. I just hope they don’t stumble anymore with poor execution. Remember that the x86 only has 8 registers, this makes life complicated for the execution core in an x86 CPU. As an example, do you understand what pipelinig is and why it is good? 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. Rather than compare which processor scores better on which benchmarks, it’s good to read about the actual architectures of the different processors. 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. Flop lead above the power 4 and still am because i felt that Intel sold themselves to design. Big move by Apple to switch from IBM-built PowerPC processors to x86 if.
