no. Because Intel is full of absolute idiots, Intel atom didn't support AVX 1 until Gracemont. Tremont is missing AVX1, AVX2, FMA, and basically the rest of X86v3, and shipped in CPUs as recently as 2021 (Jasper Lake). | ||

Intel also shipped a bunch of Pentium-branded CPUs that have AVX disabled, leading to oddities like a Kaby Lake based CPU that doesn't have AVX, and even worse, also shipped a few CPUs that have AVX2 but not BMI2: https://sourceware.org/bugzilla/show_bug.cgi?id=29611 https://developercommunity.visualstudio.com/t/Crash-in-Windo... | ||

Oh damn. I've dropped SSE ages ago and no one complained. I guess the customer base didn't use those chips... | ||
