The x86 can never be designed for a mission critical task. As an example, do you understand what pipelinig is and why it is good? Your article also makes bold claims that are unfounded and unsupported within your article or by your references. As it was OpenGL was already hardware accelerated, but Quartz Extreme allows all the compositing to take place in the GPU freeing up the CPU. 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. This wasn’t un-optimized code, and if they had utilitzed alvitec and SSE, most likely the results would have been even more dispartate. http://www.igeek.com/articles/Hardware/Processors/x86-64vPPC-64.txt. This does not invalidate the ICC SPEC FP results or justify Apple’s use of GCC. If you're a Windows user and you use tons of propietary Software, there is no other option to you but x86, unless your performance needs makes emulation somehow viable. 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. 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). There seems to be two types of people here, the electrical engineer/computer engineer type, and the GUI/widgets/font/web designer type. That’s what bothers me a bit. Power Consumption Differences The 21264 and 21364 were great designs, but they weren’t as “pure” RISC as the earlier generations. 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. We do need more of these on OS News! 8080 has no complex instructions, 8086 has plenty of them. 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. 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 … Alphas are very power hungry due to their clock tree which is a mesh with a very high capacitance. Instead they have a thing with a poorly optimized compiler that does low percision floating point ok. But overall the Talos II POWER9 had quite a respectable showing compared to the x86… 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 . First off, macOS has to support only two architectures: ARM 64-bit and x86 … The family was designed to be a low cost RISC (Reduced Instruction Set Computing) CPU, it was based on the existing IBM POWER CPU used in the RS/6000 workstations so it would have an existing software base. I may not have understood everything but I got enough. I liked the bit about the Alpha outgunning the P4 though, god i want an EV7 box! I just read my own sentence and saw I made a mistake in my post. 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. This means PowerPC Operating Systems can use a microkernel architecture with all it’s advantages yet without the cost of slow context switches. 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 original releases of MS-DOS 1.0 actually had a Digital Research copyright string embedded in them because of this.). This is why it makes sense to use x86 processors in PCs and ARM processors in phones. 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. 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.
