| These Pentium-specific traits were exploited via Abrash's hand-tuned ASM (id386.asm) delivered a 3x speedup over 486DX4-100 and AMD/Cyrix 5x86-133 style CPUs, crushing the clones' weaker floating point pipelining and marginalizing them in gaming. Pentium began to dominate the 1996 PC market as Quake's "minimum viable" software 3D benchmark, shifting devs from CPU raster hacks to hardware offload. Next, GLQuake/Voodoo (1996) hit 60+ FPS by rasterizing on GPUs, birthing the 3D acceleration era. | These Pentium-specific traits were exploited via Abrash's hand-tuned ASM (id386.asm) delivered a 3x speedup over 486DX4-100 and AMD/Cyrix 5x86-133 style CPUs, crushing the clones' weaker floating point pipelining and marginalizing them in gaming.

| Taken on an i7-12700k, a basic "unrolled LDA" example executes at 95 MIPS in the WASM version and at 675 MIPS in the C version. However, there's an issue if we go beyond this relative benchmark. | Taken on an i7-12700k, a basic loop example executes at 55 MIPS in the WASM version and at 550 MIPS in the C version.
