@Marvin I noticed that Intel gave up skylake (ID 506E3) on this release, and only my CPUID 906E9 among the 806Ex and 906Ex was increased by 2KB. BTW the ID 906E9 was the only one that didn't get support for Windows 11. I think it could be a Windows 11 supportive release.

Anyhow, The new MC gave me a noticeable better results on CPU-Z benchmark in Windows 11, but there was a huge discrepancy although there was no delay testing the same MC twice.

Old MC EA:



New MC EC:

Tested the new EC ucode on the latest Insider Win11 build, on my 8700K/906EA (kept at stock for reliable comparison results).
Performed a number of tests, CB15 and CB23, CPUZ, AIDA64. Repeated to increase reliability.
Results are a further decrease in performance, both single core and multi, from the previous EA ucode, which already was the latest in a line of 2-3 ucodes that were really bad.
Don't get me wrong, you won't feel the performance loss in stuff like games or just normal OS usage. But it's there and it's pretty substantial.
For example, my 8700k with pre-Spectre ucode would score like 1470 CB / R15, 1452 with B4 (the last "compromise" ucode before the nasty ones started to drop), 1405 on CA-DE, 1387 on EC. The single core dropped from 205-ish to 188 over the time. Somewhat depressing, considering there was not one attack with these vectors. Also the latest ucodes since CA or so decreased the default cache multi from 44 to 43.
I will probably eventually mod the last BIOS (EA ucode in it now) to B4 and then delete microcode.dat when offered to stay on the older ucode. I think that's the procedure? I'm quite done testing the new ones. Seems obvious that they're simply getting worse and worse.

EDIT:
After renaming the mcupdate thing and going back to the EA ucode, CB R15 is back to its 1405/191 "normal", but CPUZ is showing single core scores as low as 460, so EA is malfunctioning in Insider Dev I guess, at least in some apps/benchmarks.
What a shitshow. Imagine dropping from 530 to 460 in single core performance for the same CPU over 3 years.

@NeXt3R Didn't try Windows 10, no longer have a backup of it, Win11 is working OK for me outside a few minor issues so I kinda ditched 10. I don't have VBS/Core Isolation enabled, that would further tank performance. Using Kaspersky IS.
There is something with the Insider Dev build too, as the EA ucode performs worse on it than it did on the retail Win11, and worse than EC on single core by a significant margin, which was unexpected. Will probably try to return to the B4 ucode and for now keep Insider, no idea if it's a bug, the Ryzen SMT fix, or just some other stuff. No way to test either. Messy.
