Requesting data from 4850 and or 4870 owners

post #1 of 4
Thread Starter 
I am really curious how the memory bandwidth in the 4850 and the 4870 affects it performance. Is the high throughput DDR5 really necessary?

Is there any way we could get some tests from 4850 owners with stock core clocks and stock memory clocks and then high core overclock with stock memory. How high does the core overclock?

Then keep the core stock and play with the memory speeds to see how it affects performance. Also how high can the GDDR3 in the 4850 overclock?

Then can I also get some of the same data from 4870 owners?

I think this could be some really useful data for those considering the 4850 / 4870 and are not sure which one to go with.

Aren't there tons of reviews out there from websites already?

You could take graphs from them and do a comparison?

I haven't found anything that directly explores the effect of memory bandwidth on the performance.
