tldr; don't flash that new bios with the June microcode before reading this. My own BIOS (Asrock Z370 Gaming K6) can't be reverted once flashed. I won't be upgrading bios and certainly won't be disabling HT!

the hit on my 8086k(=8700k) is quite huge in memcache.

Security is always a compromise with usability, I doubt any of us run our PC's with NSA's recommended security policy, if I wanted security I'd be running OpenBSD not Windows. Not much point overclocking for 10% perf gain to throw it away with a -16% perf loss with microcode updates. I run Comodo (which the CIA hated) and my browser (FF) is sandboxed with a reduced attack surface profile.

Yea, I think my next CPU will be AMD. Intel cut too many corners.

They're a big part of the problem!

Heh. The hydra has two heads, blue team and red team.
