Weird choice of baseline CPU and even weird is that the baseline score is 2500.
i7-12700 does hardly 2000 in GB5 with the fastest DDR5.
I've not followed closely announcements, but I don't think any announced CPU has SME2 support.Doesn't ARM'S latest cores support SVE2 and SME2?
QEMU is not that slow if all you want to know is if your software behaves correctly.Those must be darn slow, no?
Hmmm...gotta test AVX-512 in it sometime then.QEMU is not that slow if all you want to know your software behaves correctly.
I don't think QEMU supports AVX-512. Though now that I look at it it only supports SME, not SME2.Hmmm...gotta test AVX-512 in it sometime then.
I don't think QEMU supports AVX-512.
The ARM Cortex X4/A720/A520 utilised ARMv9.2 for the first time. SME2/SVE2 is part of ARMv9.2 But it seems X4/A720/A520 doesn't support SME2/SVE2 either way.I've not followed closely announcements, but I don't think any announced CPU has SME2 support.
Yes, SME is an optional extension. You have the list here:The ARM Cortex X4/A720/A520 utilised ARMv9.2 for the first time. SME2/SVE2 is part of ARMv9.2 But it seems X4/A720/A520 doesn't support SME2/SVE2 either way.
FEAT_SME NO
Hmm you might be right (I use conditional as AVX-512 might be supported only to enable KVM).QEMU 8.0 CPU emulations - enable/disable flags/instruction
The latest version of QEMU is 8.0 and it offers way more CPU flags and features! There are more than 130 different CPU families and instruction sets to emulate.ahelpme.com
Ice Lake Xeon is in that CPU emulation list and AVX-512 instructions are also listed. So it should work?

Now why would Apple refuse to admit they exist?
But then aren't they preventing the use of these instructions in open source development? Or are their libraries using these instructions available for Linux?Nothing stops someone from using AMX instructions, but if their code breaks with M4 they can't complain because Apple told them not to use the instructions directly.

So dismissive. There are people who would like to run a different operating system on a Mac and sometimes within it too.
I do miss Bootcamp but WoA works (virtualized) on M chips. It doesn't need amx but super secret features only known by reverse engineering are a step back to the Appendix H days.
