What is most important for gpu?

since 6970 is on the block....i was debate with some stupid hothead in techpowerup a while ago about what is most important in gpu design, debating the possibility of 512bit bus and 64rops...however they are insist shader power(more shader!!!) over rasterization(steroid of rop/tmu/bus) and they were saying future gaming will be more shader heavy because of limited console hardware that can't output higher texture quality and better pixel modeling(as they mentioned: console gaming taking place over pc gaming), while rops/tmu can be push by clock insanely high to save die space for more shader!! ram can also be push with higher frequency as well....which i brought the example of gtx 480 that beating 5870 in most of benchmark because of 48rop and 384bit bus....then i got kicked....

can you guy tell me are these idiot's theory are right? basically this is another war between clock speed vs architecture.......

please discuss

I would have to say its all about the architecture, for example a Pentium 4@3.0Ghz and a Core i7@3.0Ghz let say they both have the same Cache and FSB over all the i7 is faster because of its architecture/design or even say a HD4870 and HD5870 for example they both have the same memory size, clock and BUS...etc..etc the HD5870 is faster/better because of its new architecture.

Yes that's is what I'm saying, even if the 4870 and 5870 had the same numbers in spec the 5870 will beat it......all about the architecture.
