CUDA core to Clock ratio

post #1 of 3
Thread Starter 
Hi all,

I've got sort of a performance/maths question for you all today...

I was thinking of the difference between a 560Ti and a 580 in performance when both running at say 900mhz for arguments sake...

I know the 580 has 512 CUDA cores, and the 560Ti has 384, but does it equate to an exact 33.3333% increase in performance...

Anyone that knows the maths, or could help me test this theory would be greatly appreciated...

Test
Variables:
~ CUDA cores, 384 (560Ti) vs 512 (580)

Constants:
~ Test beds i.e:
- Ram at same settings
- Same CPU OC (and cooler)
- same hardware (Mobo, CPU, Case etc)
~ GPU OC on both cards:
- e.g. 900mhz

Any suggestions/opinions/volunteers welcome!

Cheers,

Ishi

In straight CUDA tasks, yes, it's pretty close to the difference in cores. In games, things like memory bandwidth and amount can skew the results.

There are relative performances charts that get posted in GPU comparisons all the time. If someone can post a few for different games and programs, you'll easily be able to calculate the difference.

ahh yes, memory bandwidth... -_-'

There would be no way to equalize the VRam to make the test effective that way.

Cheers for the heads up...
