Pentium 4 SSE theoretical*
3GHz * 4 wide * .5 inst / cycle = 6 GFLOPS

(*from Intel P4 Optimization Manual)

GeForce FX 5900 (NV35) fragment shader obtained:
MULR R0, R0, R0: 20 GFLOPS
equivalent to a 10 GHz P4

and getting faster: 3x improvement over NV30 (6 months)

原來是這樣算的啊.

不過話說想到白算盤的Single Instruction computer....
如果有個只用MULR指令寫出來的OS可能就會蠻爽的!?

嗯, 我想太多了.XD
