What OpenCL uses is Compute Units and OpenCL Processing Elements.
See Geeks3D for a complete write-up and while you're there, get CAPS GPU Viewer. That'll show you the 'power' of your GPU.


This did lead me to another interesting link people here might find interesting: an openCL-benchmark database that compares the compute performance between all the different hardware including AMD CPUs and the new Intel cores that support openCL. It gives a lot of detailed information when you open the links for each piece of hardware.

Running the benchmark I didn't quite hit their listed results but I came close.

I wonder if there is a way to compare E@H crunch times with the expected results from the benchmarks...but the Nvidia crunchers are still using CUDA aren't they?

I run Arecibo 1.24 in roughly 3800secs on my 6850, am wondering how other people compare.

Yeah that seems about right, roughly 3.5x my 6850.

Anybody got a GTX 460 or 550Ti? I'd like to fill out this list of GPUs...I just really like numbers/stats; they make me all warm and fuzzy inside. :)
...and I don't have access to the E@H database...:(

Hmm, a little faster than my 6850 even with my OCed i5 2500K (@4.5GHz)...

That is quite the jump between a 550 Ti and 560 [448].

@Sid
x6 tasks is a lot...would you be able to post times for 1,2 & 3 tasks? I know it might cut you down on crunching for a day but I'd like to see the comparison times; my 6850 can run 2 tasks but the run time gets evenly split between the two (result of 6,500secs for both) with no real gain.

I read on these forums that even the 7970 gets choked by PCIe bandwidth limits running over 3 tasks...

Damn...can't edit older posts...have to re-post table... :(

Anybody out there got a 7850?

Anybody out there got a 7850? I plan to get one later this summer when the funds are available; would like to get a preview of what it'll do here.

It might be worth noting that

It might be worth noting that the times for the GTX 560 Ti [448]
were with 1 CPU thread free and 7 CPU WCG jobs running at the same time. (i7 & Linux x64)
Probably would improve times without the CPU jobs running.
