Hi all!
Does the amount of RAM on the ATI 4870 based card
affect the RAC?
Seeing as how they are sold with 512meg and 1024meg
versions,will the cheaper lower RAM card affect the
RAC production?

Thanks, Mike.

G'Day Mike,

Not sure of the 512 MB version but my 1024 MB 4870 is getting over 60,000 cobblestones by itself (so you can see where most of my RAC is coming from).

I doubt that the 512 MB version would be too much different to this, probably depends on how many threads (WUs) you try to run at the same time, I only run 3 at a time (the default setting).

I have a 512MB HD4850 which is producing an RAC of 64K now.

For HD48xx single GPU cards I doubt whether the output of a 1024MB card is any better than a 512MB card. The only time the higher RAM would be significant is for dual GPU crossfire cards.

This same discussion is going on in this other thread.

Go away, I was asleep

In short, no under normal conditions.

In long, only if you run a stupid amount of WUs at a time to the threads are bottlenecked.
