Intel may be forced to step up to the plate with a competing design, and wouldn’t that be a good thing? First off, how many of you have heard of PowerPC? I have to agree that this guy doesn’t really know what he is talking about. First off, macOS has to support only two architectures: ARM 64-bit and x86 … So they had two choice Fast Clock speed Narrow Super-pipelined architecture or wide slower clock high CPI Micro architectures. x86-64). I’d like to see a lot more of these informational articles. I have worked at both x86 & ARM -based hardware shops, although my main work is in GPUs. I just hope they don’t stumble anymore with poor execution. Power4 and Itanium both have this and it is how the win the Flop performance benchmarks and marketeering. It’s never been faster or smoother and the CPU is even more free to handle the actual Apps. Dude — an apostrophe does not mean “watch out, here comes an ‘s’ ! This is the first time I have read anything that even remotly understood the differences in the two different cpus. [13]* Article on G5 benchmarks Sorry, but you either need to explain more about what you are talking about or use more technical verbage to make the article a higher level. An instruction converter cannot remove the inherent complexity present in the x86 instruction set and consequently x86 is large and inefficient and is going to remain so. “Most people simply don’t undestand that a 50 MHz 68030 isn’t twice as fast as a 25 MHz 68040”, Well, the 040 was “double clocked” internally, i.e. Intel tried it a few years ago with the failed Intel Medfield processor. You can get a quiet heat sink and power supply for that Athlon. 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. In a recent test [11] of x86 compilers most results turned out glaringly similar but when SEE2 is activated ICC completely floors the competition. I await your informed, technical reply with great anticipation!!! Why? The design is currently also making strides in notebooks and other devices where improved energy efficiency is in demand. 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. 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. Performance Differences Between The PowerPC And x86 8080 has no complex instructions, 8086 has plenty of them. Comparing the heatsink on my Athlon XP to that on my friend’s G4 indicates similar levels of heat dissipation. Why The Difference? so i would expect ppc to best x86 for its a new clean design. x86 CPUs may use all the tricks in the book to improve performance but for the reasons I explained above they remain inefficient and are not as fast as you may think or as benchmarks appear to indicate. Both the Athlon and Pentium 4 use longer pipelines (long and thin) with simple stages whereas the PowerPC G4s use shorter pipelines with more complex stages (short and fat). However, that doesn’t mean that x86 code can not scale to higher and higher speeds. Intel still sell low power Pentiium III CPUs right down at 650MHz. (nothing from Intel yet). B,C,D,E,H and L are register names used in Z80 version of the 8080 asm. RISC may be technically better but it is held in a niche by market forces which prefer the lower cost and plentiful software for x86. http://www.apple.com/powermac/performance/, [11] ICCs optimisations can greatly effect performance A fun break from the Ryzen vs Xeon. 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. I will say, however, that PowerPCs are typically used in automotive and industrial applications which tend to us… 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. I don't know anything about PowerPC, but I can tell you some of the differences between x86 and ARM. Compared to todays CPU's the PowerPC is just OK but at the time it was arguably the best. He uses an OSNews post as justification for throwing out ICC results in favor of GCC even though the post doesn’t even address that. ... “That’s not to say that MIPS, PowerPC, and even X86 don’t have a place. Sigh. This of course takes up silicon and consumes power. However, it seems to me that at some point x86 is going to have to have liquid-cooling to keep their processors cool enough. Most of the time is is more like listening to two preaches going at it over thier own particular beliefs. The Pentium 4 is now at 3.2 GHz yet a 1.25 GHz Alpha can easily outgun it on floating point operations. It has very basic design flaws. He is quite right that the x86 is highly inefficient, and should probbably have died years ago, but it keeps getting more complex and faster. The idea that x86 have RISC-like cores is a myth. 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). With the 80386 they added flat 32 bit memory. x86 execution cores use the same techniques as RISC CPUs but the limited number of registers will prove problematic. You should really check out Arstechnica and Aceshardware, as others have suggested, if you want the real story. The reason is quite simple: power efficiency. It started as a toy and should remain that way. 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. This is how the infamous QDOS, MS-DOS’s ancestor, was created, and is part of why Digital Research eventually sued Microsoft: California Computer Systems (if I’m remembering the name right) ran CP/M’s 8080 code through just such a translator, and then wrote a native BDOS for their development system. While mobile phones and embedded devices are mostly Arm today, it is clear that x86 … I guess that you get what you pay for, as this website is free, you can’t really expect much from it. It can easily be done – it’s just that most white box builders don’t bother, which is indeed crap! Not like a lot of the fetid tripe that dares call itself a “review” that gets posted here (Eugenia’s articles excluded of course). Alongside this it is also worth highlighting that an x86 CPU can do anything an ARM can do. Even industrial machines are running PPC every day. Most of these subtle differences lie in the way memory is addressed, exceptions are handled, branches are executed etc. Is ICC really that much better than GCC? RISC = Reduced Instruction Set Computer) is a compact and energy saving, not a high performance chipset. ARM, MIPS and PowerPC have been around for ages, so I'd assume support for them would be better than for RISC-V. 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. x86 CPUs are still compatible with the large complex x86 Instruction set which started with the 8080 and has been growing ever since. The recently announced PowerPC 970 currently runs up to 2GHz and delivers performance in line with the x86 CPUs. I don’t know well realwordtech, but ars technica is really a good reference, even if it is a bit PC biased. Maybe I’m thinking of the 21164 rather than the 21064, but I know that later generations (21364 and possibly 21264) started using things like instruction reordering that are less in line with the principles of RISC. A great power consumer is the clock tree. 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. Current iterations of rendering software, for example, are using the GPUs in that way. 8). Despite performing better than the best existing 32 bit Athlon, the Opteron has a slower clock speed (1.8GHz Vs 2.2GHz). Additionally, current G4 CPUs use a relatively slow single data rate bus system which cannot match the faster double or quad data rate busses found on x86 CPUs. My first PC was a Radio Shack system, I learned to program using an IBM PC using BSD Fortran 77, then Pascal and of course I taught myself basic as well. I’m not surprised really that Intel’s ICC compiler vectorizes Spec’s FP intended instructions. …system throughput will still exhibit the combined delays of the other components.” [3]. Don’t get me wrong, the x86 is a true piece of engineering excellence, taking something that’s not that great and inefficient and making it good enough to satisfy the current user base to fanatical points where they berate powerpc users on a common basis. And for me, it seems a lot better than realworldtech. “The Talos II server with dual IBM POWER9 22-core servers ended up delivering performance around that of the EPYC 7551 previous-generation Naples processor. The 100% improvement just sounded inflated to me. 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. At the end of the day, both cores cannot be compared in terms of technology node because their implementation depends on a third party. But the bootom line is that Intel intended the 8088/8086 to be a 16 bit extension of their 8 bit 8080 which came from the 8008 that owed it’s start to the 4-bit 4004 processor used in early calculators. I wonder why some basic features were not covered like Out-of-Order execution and Branch Prediction which seems to be the major items commonly found on current IA processors. I also question how much linux is really cross platfrom. 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. I’m not the only one to hold such an opinion: “Intel’s chips perform disproportionately well on SPEC’s tests because Intel has optimised its compiler for such tests”[13]* – Peter Glaskowsky, editor-in-chief of Microprocessor Report. My main point was that the guy was pulling numbers out of his arse. the 25MHz 040 was indeed running at 50MHz internally (much like the R4000 for example). I really don’t think it. In this rendition. How many people really need a computer that’s even over 1GHz? Why do you think Microsoft is so lauding similar technology for their future WIndows 2007. The Pentium 4 M can reduce it’s power consumption but only by scaling down it’s clock frequency. The answer to this lies in the fact that MorphOS runs on PowerPC and not x86 CPUs. The massive growth of the computer market is ending as the market is reaching saturation. Kudos!
