Lacking ability to virtualize 圆4 operating systems. Partially it's Intel's xeon pricing that is to blame but lets see what Apple does with pricing without the high priced Xeons being a factor. I just hope it's not as expensive as the current intel Mac Pro, which is insultingly overpriced considering how much more affordable AMD Threadrippers are. I think Apple's approach of building a SOC that is efficient on battery is going to give their workstation SOC a lot of headroom due to the efficiency. I suspect they can push these things a lot further and perhaps with faster single core performance. Lets see what Apple does when they build the Mac Pro version. So far they've all had to meet the "on battery" requirement for iphones, macbooks, even ipads. I think Apple can do a lot more with their chips. They could add an obscene amount of cores to it and intel would have a hard time competing with it, even if they beat it a by a few points in single core performance. We've yet to see the Mac Pro version of the M1 or M2. That's why we have graphics cards, AI coprocessors, secure enclaves, T1, etc if ARM doesn't have an instruction for it, who cares, just build it in silicon elsewhere on the die. But, that's not really an issue for Apple, because M1 isn't just a processor its a system-on-chip. Over the longer term, as manufacturing processes get smaller, CISC as a philosophy may edge out pure-RISC, because it becomes more and more possible to fit more complex instructions within a power envelope and physical die. In the chip world that crown always gets traded around Intel is due for a victory lap here before too long. At the end of the day, I wouldn't be looking at RISC vs CISC to explain why Apple has a significant efficiency advantage its moreso just better, more specialized engineering. Its, of course, a much much lower cost some would say negligible. Whether that's complexity in implementation, or even physical space (code isn't magic, it has to live somewhere). There's a follow-up argument in that, even microcode has a cost. Which is why Intel has, in recent history, begun to move more and more of these to microcode, on some processors (especially consumer/low power ones). Its just not something most modern programs run into. Of course these extraneous instructions are rare. When a compiler encounters a situation which calls for one of these more complex operations, it may generate a single instruction for x86 but it'll generate many instructions to emulate that same instruction on ARM. What we're talking about are ISA instructions which don't even exist in ARM.ĪRM's scope of instructions is much smaller than x86. Not really, and I'm at something of a loss for where this comment is coming from. Reducing instructions to microcode to free up die space for more power efficient cores puts x86 at a disadvantage.
