I found the statement that the RSX in the PS3 can do 1.8 Teraflops a little absurd. So I decided to do some research on it.
Here we have Sony's initial claims:

Note the number of FLOPs (floating point operations) per clock. 384 to be exact. Now its time to do a little multiplication. Multiply the number of FLOPs by the RSX's clockspeed, which is 550MHz.
384 x 550,000,000 = 211,200,000,000
211.2 Billion is the result. That ends up being 211.2 Gigaflops. Thats right, Gigaflops, not Teraflops.
211.2 GFLOPS = 211,200,000,000
1.8 TFLOPS = 1,800,000,000,000
That means that Sony has exagerated the power of the RSX by a factor of 8. In fact it is 7 Gigaflops slower than what Sony claims for the CELL (218 Gigaflops). Makes you wonder how exaggerated the CELLs power is. Considering that Sony is being truthful about the CELL, that means that the total system power is only 429 Gigaflops, which is nowhere close the 2 Teraflops that Sony "claims" the PS3 can do.
Does Sony think they can get away with such deception? If you know any die-hard Sony fanboys, make sure they see this. I think they need to know the truth
