Wouldn't x86 have the higher code density? https://www.vogons.org/viewtopic.php?t=56207 https://www.vogons.org/viewtopic.php?t=56207 "Finding an IA-32 CPU most like the MIPS R3000A" "a 40MHz MIPS R3000 gets 18.1 MFLOPS, while a 66MHz 486DX2 only gets 3.1 MFLOPS. So, the MIPS is downright Pentium-class for floating-point code. For integer code, the MIPS R3000/40 manages a score of 22.6 in SPECINT89, while the 486DX2/66 gets 34.0" So its also only "Pentium-class" for floating point math, not for integer.

It should, by nature of CISC. However, the other coprocessors on the playstation meant you weren't wasting all your CPU cycles on rendering, which was the majority of the time on a 3D game of the era.

The PSX CPU did not even have floating point support. It's nowhere close to a Pentium 90.

  It’s a video game system. You can make do without floating point. The whole “it doesn’t have fp so whobbly textures” is a myth.

  It did have a fixed point vector coprocessor instead though.
