#AMD released the 7th #Zen6 pdf "Guest PMC Event Filtering" 69202 v1.00: docs.amd.com/v/u/en-US/6920… CPUID Fn8000_000A_ECX[3] = #GuestPmcFiltering #Virtualization


I like this kind of progress: not only has the DIV/SQRT throughput doubled, as the #Intel #LionCove slide suggests, but their latency has also decreased. The cross-line permutation speed, which has remained unchanged since #Haswell, has also doubled.






There are a few working #PantherLake B0_2 among #Intel test machines: (CPUID C06C2, 12c/12t (4P+4E+4LPE probably), 3.0 GHz base freq, no HTT & #AVX512, Intel 18A) intel-gfx-ci.01.org/tree/intel-xe/… #CougarCove #Darkmont For comparison, #LunarLake was 3100MHz (8c/8t 4P+4LPE) at similar stage




According to this GCC patch, the entire B80Fxx-BE0F7x CPUID range is mapped to #AMD #Zen6 cores, except for the BD0F0x-BD0F7x range. I think this exception might be some #Zen5, maybe the unreleased #SonomaValley? github.com/gcc-mirror/gcc…








They're BACK! More 9800X3D CPUs go up in smoke! But why? youtu.be/EiUtw4w3CQc?si…
