Breaking the GHz barrier with a CPU was easy...

[KemoKa]

A really stupid question that has probably been asked time and time again, but seeing as the GHz barrier was shattered to pieces by AMD's Athlon 15 years ago. right now we can overclock several processors to 5GHz with few if any issues. Which is where I come to GPUs. Why is it that we have yet to break the 2GHz barrier on stock-clocked GPUs? is it an architecture thing? Is it the matter of GPUs just taking loads more power by their very nature? If that's the case, then okay, but I can't see very many reasons as to why someone hasn't clocked their GPU to the balls yet. Power delivery would probably need to be insane, but... Would there be any benefit to a superclocked GPU?

And kingpin has already said he has gotten way past 2ghz on a 980

Not stock but neither is 5ghz on a cpu. Gpu's have thousands of cores, it is a little different than a processor. Especially since the amount of cores is more important than the speed when it comes to gpu's.

Also the GPU core makes so much more heat than the CPU core that GPU's are incredibly limited by thermal headroom. Remember, a gpu has well over 2000 cores whereas a CPU has only 4/6/8

That's cool.

 

the 9590 is factory-overclocked to turbo to 5GHz. Still counts as stock in the tech talk shows I've seen. Isn't practical though.

That is on LN. ;(

If gpu's and cpu's worked the same then we would only have one of the two. gpu's have so many more cores that taking all of them up in clock speed produces allot more heat and makes it more unstable, so we are left to minor changes, that ironically can result in huge performance gains in games.
