>These days, Intel and AMD put fairly little effort into making x87 instructions fast, because code that cares about floating point performance use AVX instructions.

AFAIK x87 instructions were removed/deprecated in x86_64

AMD64 (x86_64) can still execute x87 instructions. Not much point, though, unless you need 80-bit precision.

SSE / AVX just performs so much better.

Precisely what it's good for.
