Can you provide or link to any proof or information on the Cinebench claim? That's quite a statement which I haven't seen presented anywhere else. I run what I believe to be the largest database of cinebench scores (cbscores.com) so have a somewhat vested interest to look into this. To the best of my understanding, AMD performs poorly in certain tasks and benchmarks because of its shared use of FPUs, despite shipping consumer cpus with 8 cores, they only have 4 FPUs, which given benchmarks like cinebench run almost nothing but floating point math, would rather explain the results.
But hey, I could be wrong and there might be a giant conspiracy from intel to artificially slow down their competitors. Feel free to contact me privately if you prefer and I may be able to look into it further. mash at 3dfluff.com.
