All I need to do is to quote myself,

XENOS is better than RSX, slightly.

CELL does run more floating point operations per second than Xenon, actually its much more.

XENON can handle more instructions per second than CELL, about double.

*PS3 Cell specifications

...

*1.8 TFLOPS floating point performance

Where did you get those numbers? :)

"The first optimization for the SPE architecture was to take advantage of the four way-SIMD using 32-bit multiply-and-add operations to perform up to eight single-precision floating point operations per cycle."

...

"Using eight SPUs, the parallel version of matrix multiplication achieves 201GFLOPS, very close to the theoretical maximum of 204.8GFLOPS."

(Plus PS3 has only 7 SPUs and its has lower clocks.)

RSX is more 7600GT than 8600GT.
