Noob question incoming. . . does anyone wanna explain core and mem clock?

[MPX309]

thanks

You're talking about graphics cards right?

 

Core clock = the graphics processor speed

Memory clock = ram speed

 

For instance, your Sapphire R9 270x has a core clock of 1030mhz, and a memory clock of 1250mhz.

Core clock = the graphics processor speed

Memory clock = ram speed

/|\, adding on, over clocking Core clock is better than Memory clock, generally the ram speed is just fine. Higher Core clock Better graphics (with 2-4 gigs of ram on the gpu)

plus all that...

 

1250mhz or DDR3 Vram (this is the gpu ram) = 2x 1250mhz = 2500mhz of eVram

 

1250mhz or GDDR5 Vram (this is the gpu ram) = 4x 1250mhz = 5000mhz of eVram

You can check the guide in my sig for memory clocks and memory bandwidth in detail (the vRAM guide).

 

Core clock is the raw graphics processing power; this works in tandem with the number of cores (cuda cores for nvidia, stream processors for AMD, if I remember right) and the architecture of the card (for example each Fermi card (gtx 400-500 series) has cores that are hot-clocked to 2x the listed speed, while kepler (GTX 600-700 series) are at a 1:1 speed. Therefore 300 fermi cores @ 1000MHz = 600 kepler cores @ 1000MHz, etc) to provide actual graphics-rendering horsepower.

 

Memory clock is more used for pushing texture information etc. It usually has a far less pronounced impact on gaming, unless you run into one of those rare games where it really benefits from a faster memory clock. These games are so rare I don't actually know of any offhand, but in general more won't hurt.

depends on the memory bandwidth. a gtx760 will benefit as much or more from memory overclocking in some cases, while an R9 280 will usually benefit more from core overclocking.

the above 5 dudes have explained their points

 

 

once you read all of them

 

you get this

Memory clock = ram speed
