Are you saying the X87 FPU exists again?
How do you think 15h generation can run x87 code then? Of course they have hardware for it, it's part of basic ISA .
They sucked at it since apparently there is some "un-optimization" going on in hardware when these instructions are in question. That's how the chip was designed, the latencies for x87 instructions are noticeably higher vs 10h generation.
