> Later, it was reduced to a more narrow role as a server and high-end desktop processor and was used in supercomputers like ASCI Red, the first computer to reach the trillion floating point operations per second (teraFLOPS) performance mark.

Amazing. RTX 3090 has peak fp32 performance of 35 TFLOPS.

I believe that almost all floating point instructions on the Pentium Pro had the same performance whether you were using the x87 FPU in 32-bit, 64-bit or 80-bit mode, so it's probably more fair to compare ASCI Red against the fp64 performance of today's GPUs. NVIDIA usually doesn't let the consumer GeForce parts get anywhere near 1 TFLOPS for double-precision. You have to look at some of their Titan or datacenter GPUs to get that kind of double-precision performance.
