Now this is interesting, some of those microcodes are quite a jump in size from previous versions, as I was interested in 406F1 I noticed that it has changed from 31KB to 35KB in a single version, most previous releases have been 1 KB larger every few versions or even keeping the same size over multiple versions. Some of the 27 new ones are the same size or 1 KB larger than previous, those are boring, but the interesing ones: 306F2 34 > 38 KB (4KB larger, 12% increase) 306F4 19 > 23 KB (4KB larger, 21% increase) 406F1 31 > 35 KB (4KB larger, 13% increase) 50654 36 > 42 KB (6KB larger, 16% increase) 50663 24 > 28 KB (4KB larger, 16% increase) 50664 24 > 27 KB (3KB larger, 12% increase)
And all of these size jumps are in the window of about ~3-4 months from previous version (not comparing years old size to current size).
So either Intel is heavily optimizing all the Spectre etc recent years vulnerability workarounds or there could be a workaround for a yet to come new vulnerability.
Windows 11 is about to be released any day now. The FINAL non-beta, non-preview, the release version of Windows 11. These new microcodes are from the NEXT development branch of Windows 11 - it is HIGHLY doubtful Intel did any work on these older generation CPUs for any sort of Windows 11 "tuning".

Maybe if you consider Skylake-W Xeon and Skylake-X core i9 (79xx X/XE) old. Skylake-X is testing fine on Windows 11 beta builds with previous cpu50654 uCode from March. But, remember Microsoft added Skylake-x/w (cpu50654) late to the compatibility list late… maybe you’re right and it’s all security or maybe there is something in there that was needed to make windows 11 work better for cpu50654 Xeons and Skylake-X. Intel need to support corporate Xeon customers more than few years…
@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.
It’s a long story but Intel has basically provided multiple ways of telling if a CPU was invulnerable to Spectre etc bugs via reporting different MSR bits (basically CPU features), they are now implementing it via IA32_ARCH_CAPABILITIES on at least in your example for the first time.

hi JEN1
what CPU settings are you testing it on ??
stock OC 3.9ghz //75A / 2400mhz RAM ?? what was it about
I was afraid that OC would not work on this microcode 7820hk 4.5GHZ + EC mc works fine/or better
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.
