ATI Radeon HD 4000 Series discussion

Not quite true... The Pentium D on 65nm didn't surpass a 90nm A64 x2. The Prescott didn't surpass the 130nm A64's either. Nor did the R600 surpass the G80. We also saw what happened with the RV670 vs G92.

Process can help you do more in a single chip, or lower power consumption, but it doesn't make for a better chip in all cases. Besides, by the time we see larabee, we'll see both ATi and NVidia on smaller processes than they presently are, and intel have stated larabee will be 10x the performance of their best IGP, which would only align it with the G80...

I didnt say it would do miracles. But if you are some 10-20% behind on the same process. You can catch up with a forward process. 65vs45nm etc.

P4 is also a whole other issue due to leakage at extremely high frequencies.

Inferiour product on a better process can change the tide.

For those with reading comprehension problems. Can change doesnt equal to will change.

Oh, Larrabee IGP on value Sandybridge will be about 10x of G33 with value Nehalem being some 6x. They havent disclosed any discrete GPU performance hints.
