Difference between Core Clock and Memory Clock

[evinta]

Hey guys.

 

So im just looking at my video card on afterburner and saw those two terms. What is the difference between the two?

Core Clock - what the GPU's core is clocked at, like how the GM204 core in my GTX 970 is clocked at 1530MHz.

Memory Clock - what the VRAM is clocked at, like how the GDDR5 memory in my GTX 970 is clocked at 7010MHz effective.

Memory Clock - what the VRAM is clocked at

^This, I wouldn't worry about Memory Clock it doesn't impact performance enough to justify OCing it. Core clock is what you want to OC.

Actually i've underclocked my GPU core because its starting to die (it was brought in 2010 by my dad) so im currently running it at 800mhz. Memory clock is at 1000mhz atm.

 

So its basically memory = RAM and GPU = processor?

Just what is says. The GPU (core) runs at a certain frequency, the GDDR5 memory where it stores its information runs at another frequency.

Only the GPU is considered a processor, RAM doesn't process any information. RAM is only for storage of active data that the processor is working with.

Not sure if a 5800 would have GDDR5 memory.

 

Makes heaps of sense. thanks.

Bwahahaha...Fair point! Well anyway, to be more specific the memory clock determines how many operations (store or retrieve information as requested by the GPU) the memory can do per second.
