Does one GPU always run hotter than the other?

Hi all,
I was playing Left 4 Dead for a couple of hours last night and when a quit I checked my GPU core temps and the 1st core was 68C-70C and the 2nd was only 58C-60C. Is it normal for the 1st card to run hotter than the 2nd and is one card working harder than other, if so how can i share the workload equally. Please advise. (Maybe this has already been discussed before if so please delete this post and tell me where to find some info)

 

Yep, a few degrees difference, upto a max of 10C(18F)is normal.

 

well yeah it is normal for a gpu to have one gpu to be hotter than the other.

an app may choose to use only one (usually the 1st core) at a given time, or both, both depends on the application (games) and what the application is doing at that time. sometime only the 2nd core is used and not the first one. there is really no telling, depends on how the developer or the driver decide to best use the cores.

look at your cpu, usually the first core will work harder, then the second core, sometimes only the second core works, and the 1st idle, sometimes both are working but one is working harder than the other, there is no telling. it all depends on how the software is utilising the processor.

and no, to my knowledge you cant share the workload equally. if its even possible, why would you? it is already optimised to work that way. processor have different pipeline if you will, that process different thing, if one is used, the other processor pipeline might get utilised to process the instruction, to speed up the process (assuming the application is optimised for multicore processor). its just how the processors works.

 

Your temp difference seems within the norm. Some games have an option you can set to use dual cards (I believe COD4 has it). I dont remember if Left4Dead had that option. Either way it doesnt mean that the temps will be equal between the two cards.

Also, the location of the cards within your system can have an effect on the temps. Although you have a Clevo D90 rebrand. And from what I hear, it has the best laptop cooling system in the world, so I dont believe that should be a significant issue.

 

Nice laptop.
