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. [/quote]

and you tried windows 10 ??
for my 7820hk - all this microcodes look identical "in bench cpu-z or XTU" // latest ME fw
win 10 21h1
+- 15 point - for me zero effect
i using very accurate voltage "AC/DC LL 0.01" - and still need identical voltage for stability
for my CPU - is all identical
edit
or try disable new functions in DEVICE SECURITY "in window 11"
