Mac With Apple-Designed Arm Processor Coming in First Half of 2021

Amazon Graviton 2 ARM64 32 cores processer. AWS instance type M6g family and upcoming C6g/R6g family.
Core by core faster than Intel Xeon. 32 cores at 105w.
I guess that should be faster than 28 core Xeon? At least it will be much faster than a 16 core Xeon.

How do you figure? People will Hackintosh ARM based systems, which will likely be abundant by the time Apple pulls support for Intel chips in Mac OS.
Having two platforms will severly limit the willingness of the big 3rd party players to make high-end applications for 2 different Mac platforms. We'll gain "toy" level apps for the iPad and loose anything worth having.
ARM will still be lacking some x86 extensions for some applications that have significant implications. In some apps it won't matter, but others the lack of SIMD type acceleration will make a big difference.
You do realize that goes against your entire argument that no one cares about compatibility compared to performance, right?
"Intel will never run SIMD like PowerPC with AltiVec" just a bit more than 15 year ago.
Actually both of you are off. SunOS 386i came out in 1989. Sun was originally M68k, then i386, then SPARC, then x86 again.
Servers back then were IBM AS/400s and mainframes. Sun was interested in workstations, not servers.
AltiVec is still PPC-only... and porting software using AltiVec to SEE is a total pain the ass. You just keep up with the self-owns.
SIMD is a way to get around the x86 tax. It means you only need to decode and schedule the instruction once. Why high-performance architectures like POWER aren't as wide as AVX.
That's OK but I still like to run Parallels to run old legacy games on Windows and I did want to buy a new Mac that would allow me to also run Boot Camp. How will this affect me in regards to my legacy games.
Look at the date. Post 1995, when it was clear that PCs would dominate.
Sun couldn't cut it in workstations, so they switched to servers (having to buy Cray for the high-end stuff), and when that fell apart, they died.
Quick questions:
1. Do you write code with SSE assembly?
2. Which library you frequently use is inline assembly optimized with SIMD?
3. Do they support ARM?
NT was awesome on powerpc. we used to use it to test the x704, and it ran way faster than Mac OS.
Little reason to, since it's unlikely that there will be third-party ARM boxes that are more powerful than what Apple puts out. Apple may also beef up the secure enclave, and make it very difficult to install mac os on boxes without its own processor (which, in fact, may even have an instruction set that includes instructions nobody else has).
Except for Apple themselves, making Mac on ARM will be *hard* as you suggest. For us programmers, not as hard, though there's likely to be gotchas, for users, maybe no difference at all, but I don't see it being very fast, especially the x86 emulation.
I wonder if Apple will still use an x86 CPU as coprocessor (AMD perhaps?) or go all in on this with their ARM CPUs...
Either way, I doubt it will be mature before 2024.
Either way, I doubt it will be mature before 2024.
And by 2030 most of the apps you use will be re-written to be compatible! Except Adobe.
Yes, it's called the T2 chip, which could be replaced by a T3 or T4 chip (just next gen naming). This new chip could be used to virtualize the X64 environment and currently used functions (e.g. translating ARM to X86 using bridgeos) would become obsolete.
No chance they do that. They already have ARM chips in macs, so this is all about getting rid of x86.
