New Microcode of Skylake X 50654 fixing AVX2/AVX512 performance penalty is coming soon.

According to Intel 02007006 microcode DATE 2023-03-06 for Skylake X SKUs ( CPUID 50654 ) patched on R6E 3801 Official BIOS. The microcode above prevented " DOWNFALL " vulnerable issue attack on " GATHER " instruction of Skylake X Series CPU. ( aka Core i9 78XX-7980XE ).

Even it prevented " DOWNFALL " vulnerable issue efficiently but on other hand it cause side effect of Skylake X CPU performance. Specially FPU units those microcode slow down FMA3/AVX2/AVX512 performance penalty 30-50%. 

Now Intel's engineer had been complete working on these issue.

 

The new microcode was publish on 2023-07-28. To bring back Skylake X FPU performace. 😁
