Graphics Card specs

I was wondering if anyone could answer this.

Why do modern days graphics card have such low Mhz/Ghz rating on the GPU core?

Ive only seen cards go upto about 900mhz with the newest cards. But just doesent seem a big step up from a card I had 5 years ago at 500mhz.

I was wondering if there was any limiting factors why higher clock speeds cant be reached. considering CPU's clock speeds have been over 3GHz mark for years.

Just think what a GPU could do at speeds of 3GHz or more.

Im no way a techie, But ive always wondered this. Hope someone can shed some light.
 
no to the cooling really, mainly a 500mhz card today would kill that one, even with the same number of cores. and todays cards have wayyyy more cores on the ati/amd side, while nvidia uses cuda cores which have much less super powerful cores, so they even out. it's like putting a i3 2100 vs a pentium d like mine, even at the same clocks, they will appear the same spec wise (other than the i3's threading) but the i3 will bare minimum double the performance in any given task. and for the question of cores over clocks, think about what a gpu is doing, it process millions of small lines, so having a ton of slow cores doing all this at the same time is better than a few super fast cores doing a little very fastly.

PC EYE, is that you???
 
...what did happen to "google eye"? I haven't seen him around for ages...

Anyway, it's to do with the way they're built. Due to the insane amount of processing cores, the dies of a high-end graphics cards can be a good 2-3 times bigger than those of high end CPUs so of course there are heat issues. Also, 5 years ago we were still using fixed-function pipelines whereas now we're using shaders, with very much different architectures so the clock speeds just aren't comparable.
