Gpu temps vs cpu temps, why is it ok?

post #1 of 9
Thread Starter 
Ok, so why is it ok for a graphics card to hit 80, when its not good to hit 65 with a processor?
just wondering

GPUs have more tolerance.

Every IC has a thermal specification. This is often based on design, manufacturing tolerances and the materials used to build the package. For example, ceramic industrial grade IC's have higher thermal specs than plastic commercial grade parts.

Since the GPU and CPU design is so different, the thermal spec is going to differ. Simple as that.

its the same silicon in the end, melting point 120 something i guess..

Eh? Wikipedia lists silicon melting point at 1414 °C lol.

It's as Sheyster said. I think the process (45nm, 32nm, etc) used to make those chips also has an effect, ie. smaller process usually means less heat tolerance.

because gpus cannot reliably keep the cards below 70C at low noise.

truth is gpus shouldn't be kept that high in temps. but because it's so hard to cool these massive gpus, nvidia and amd just say that its ok. it may be true, but gpus have much shorter lifetimes and will die before your cpu.
