Oh, just to clarify 3.8Ghz was the turbo. Poor wording on my part. I think the default 1 core boost was 3.9Ghz and 4-core was 3.6. Was clearing up that is is somewhere in the middle.

Took it back to 4.3Ghz and I'll test later today.

Also, the GPU was at 1100Mhz.

Is that the proper clockspeed? And are you using turbo?

Plain Jane stockety stock, turbo's on but not going to do anything with all the cores active. If it did there might be a fire and alarms would go off at the nuke plant down the road. :)

Here are my socket-only results:

Stock (3600mhz 4 cores)
20m 13.235s
Device time for pi calculation: 1185.106 s
Device time for memory reduction: 28.129 s

4000
18m 16.624s
Device time for pi calculation: 1069.509 s
Device time for memory reduction: 27.116 s

4400
16m 34.737s
Device time for pi calculation: 968.094 s
Device time for memory reduction: 26.643 s

4600
15m 51.754s
Device time for pi calculation: 925.782 s
Device time for memory reduction: 25.972 s

4800
15m 13.210s
Device time for pi calculation: 887.096 s
Device time for memory reduction: 26.114 s


Looks like an HD7850 is roughly 10x faster than an Ivy Bridge i5 for this.

Well if you think it's not kicking in, I can omit it I suppose.

Not surprising. I'd still like to see a 5820k or 5960x do the CPU version of the test. Would be interesting to see.

More scores added. ShintaiDK is now the one to beat!

If I can get my 280x to keep a 1250Mhz clock I might have a chance. It's time to RMA it anyway. It's been unstable since I got it.

Drooling over that 980 though.

I think that's just the way it is with these, my ambient is low and temp are fine, but the higher clocked FX just aren't programed to do much turbo-ing unless it's under load on one or maybe two modules. I had an 8650 that I disabled it and just clocked it up, wasn't a significant enough difference to matter other than in benches so I just left it alone. And bought a 9590 that was "overclocked" out of the box. The lower power FX chips are supposed to have more aggressive Turbo since they have more margin for heat/voltage I've read.

For some reason it won't allow me to do the CPU test. Nothing shows up in the drop menu.

I have an i7-4700EQ system I'd like to run this on. But it refuses to run. The openCL and the standard exe both will not even start. It is win 8.1-64.

If you guys have any technical issues running the program, please report them in the author's thread. I do not understand why the program would refuse to run on functional CPUs.

sm625, do you get any errors when attempting to run the program?

DrMrLordX, My GPU is a 780, not a 970. (although it might have been if i'd been able to wait 2 or 3 months)

Update: looks like _mat_ over at XS has weighed in on the issue of GPUPI behaving strangely (or flat out not working) under certain scenarios.

Looks like it might be an OpenCL driver issue. Maybe?

Anyway, he has a handy support thread that may help. Anyone that is unable to get the program to run on a particular part of their hardware (Intel iGPUs, CPUs, etc) is advised to check it out.

Thanks for the continued input. biostud, any chance you could run GPUPI on your CPU? I am interested in seeing Haswell-E results. It shouldn't take but a few minutes to finish 1b.

Hi again, just wondering about the consistency of the table, for instance you put my time as 50.876s which is (Device time for pi calculation: 49.949s) +
(Device time for memory reduction: 0.927s) but for biostud's 7990 result they weren't added together.

I'd like the faster GPU results to be added to the table.
