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: Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc cpuid aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg cx16 xtpr pdcm pcid sse4_1 sse4_2 movbe popcnt tsc_deadline_timer xsave rdrand lahf_lm abm cpuid_fault epb invpcid_single pti ibrs ibpb stibp tpr_shadow vnmi flexpriority ept vpid ept_ad fsgsbase tsc_adjust erms invpcid xsaveopt dtherm arat pln pts -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
