What are MIPS(ALU) and FPU (MFLOPS)...

[imported_goku]

Performance of CPUs is calculated in ALUs and FPUs. IIRC the FPU was added to all CPUs some time during the 486 era or ATLEAST the pentium era? (for calculations) And it's continued on from there. So I'm wondering, what do games benefit more from, ALUs or from FPU? If you had a higher FPU, would you have better video encoding performance than if you had higher ALUs? Please explain this, thanks.

Although im not sure on your question, which is best for games, maybe someone like "pm" could tell you.

Actuall for MIPS to what I was referring to would be this: http://en.wikipedia.org/wiki/Million_instructions_per_second
