Lucky me obviously had a time machine when I bought my Haswell systems (x86_64-v3) in 2013. Though, for the Pentium and Celeron budget line, you have to wait until 2019 (Icelake) for AVX2.
Win 11 runs on e.g. a Celeron G5900, which is v2 only (no AVX).
2017 Kaby Lake Pentium G4600 not yet 6 years old not only lacks AVX/AVX2, but also v3's:
BMI, BMI2, F16C, FMA, LZCNT
My 2013 Haswell Pentium G3220 falls short of v2, unless LAHF-SAHF & SSE3 are aliases to something else it does have:
You removed the context from the quote. This was a response to:
Windows 10 and -v3 were both first released in 2015.
Core-i3/i5/i7 Haswell from 2013 has AVX2. This does not imply all Haswells support AVX2. I even mentioned Pentiums had no AVX2 until 2019 (i.e. 3 years ago) - both your Kaby Lake and your Haswell Pentium are older. Stefan
