Looks like Diamond Rapids is also getting an updated version of the APX extensions.

RISC-V just ratified RVA23 (a huge milestone), and yet we're getting excited (?) about x86's newly added cruft for some reason.

There aren't any RISC-V devices with competitive performance to leading x86 or ARM designs. I very much want RISC-V to succeed, but most people won't care until performance / cost hits a beneficial ratio.

RISC-V has not demonstrated anything worthwhile yet, nothing for consumers, nothing for enterprise, meanwhile x86 is still the backbone of the HPC world.

RISC-V fanboys are really weird, probably part of the same group as Rust cultists.

1. You're right, nobody cares.
2. I read the big RVA-23 announcement and it's just some statements about tacking on some vector extensions and hypervisor extensions. In other words, the magic of RVA23 is to tack on "cruft" that x86 chips have supported for decades. As such, I'm vastly more excited about improvements in Panther Lake vs. paper risc-v announcements.

Diamond Rapids also including AVX 10.2 according to the displayed extensions.

Even more exciting is that this confirms we have FRED for Panther Lake.

Phoronix: Intel Preps GCC Compiler For New AMX & ISA Features Ahead Of Diamond Rapids

Intel's compiler engineers today posted a number of feature patches for the GNU Compiler Collection (GCC) for enabling new ISA features to be found with next-generation Xeon "Diamond Rapids" processors. Excitingly a number of new Advanced Matrix Extensions (AMX) features are coming with next-gen Intel Xeon...
