Post your Multi-GPU OpenCL score, using v0.45 of this app.
DirectCompute & OpenCL Benchmark. (By Pat.)

http://www.ngohq.com/graphic-cards/1...benchmark.html

Version v0.45 is special. It has outstanding Multi-GPU workload balance.

Version v0.44 looked like this loaded up:

First 1/2 of my 295 reporting 61% utilization...
Second 1/2 of my 295 reporting 58% utilization...
280 checking in at a whopping 92% utilization... (Go Dedicated PhysX processor!)
Very light CPU utilization, showing only 2%.

Best score generated on v0.44:


New improved version 0.45, with better workload balancing...

97%, 98%, and 98% GPU utilization... Sweet!
CPU now up from 2%, to 34% utilization.

New High score running v0.45 with all system settings the exact same as used in the v0.44 test. Score is up from C1786.0:


This is a good OpenCL test to show off Multi-GPU Rigs.

Combined OpenCL Benchmark:

New high score...

Q6600@ 3.81GHz
(1) 295, and (1) 280 both set to Core=702, Shaders=1512, and Memory=1188.

C2575.6!!

Note that both 1/2's of my 295's Workload Share is now officially above 30% (almost 31%), and that my 280 still is doing the lions share of the work at 38.43%.
I also verified that my clocks stay in 3D Performance mode for the entire duration of the test.

Needless to say, I love this app, and if the Combined Direct Compute test starts to work as good as the Combined OpenCL test does, this may become my favorite benchmark program.
I hope the Combined Direct Compute Test also produces a Workload Share report.
That will also be some fun numbers to look at.

UPDATED:
The latest scores: http://www.evga.com/forums/tm.aspx?&m=85501&mpage=1

So that means:
A 8800 GTS and a single 4850 produces around C453

A single 260 produces around C707

A single XFX HD 5770 1GB produces around C1042

A single 295 OC'ed (using both sides of the GPU) produces around C1431

A single 4870X2 OC'ed (using 1 GPU) produces around C1974

A single 4890 produces around C2350

Two 295's @stock running Quad-SLI score around C2549

A single 295 and single 280 OC'ed produce around C2575

A single HD 5850 @ stock produces about C3034

A single HD 5870 OC'ed produces around C4058, C4248, C4405

A single HD 5970@ 950/1150 produces around C5170.9

Note that Nvidia guys run with high CPU utilization in the OpenCL test, and ATI guys run with allot lower CPU utilization... Not sure why.

Us Nvidia guys are also producing a much lower Direct Compute score: (This is still A one GPU test only.)


But this test does have low CPU utilization, just like the ATI boys...

Thanks!

Neither of the GPU tests puts any load on my CPU

The OpenCL bench only loads one core of my X2 card


The DirectCompute bench loads both cores of my GPU, but the 2nd core stays at 2D speeds unless I force them.


the scores were:

ATI Radeon HD 4870 X2 @ 790 MHz (1002 / 9441 / 2661043)
Intel(R) Core(TM) i7 CPU         920  @ 2.67GHz (8 logical CPUs)

Benchmark version: v0.45
DirectCompute: D1627.3 (D2486.6 with 2nd core forced to 3D clockspeeds)
OpenCL: C1974.0
CPU: M79.3 (M75.4 OpenCL Device)

ATI Radeon Kernel Mode Driver
atikmdag 8.01.01.984
Windows 7 x64 Ultimate Edition (build 7600)

I don't believe the combined test is working on ATI GPU's yet...

Pat is working on it.

Thanks for the post.

My result

5970 @ 950/1150
Q9560 @ 4.1Ghz

Thanks...

Here ya go... just a quick 4850 + Q6600 OpenCL Bench for you guys, just so that I can come first (from the back :p)

[Meelis S]

Hi

Ati HD-4670 OpenCL benchmark took 40 min to complete.
480 GigaFLOPS, 47W-59W card

[KillBill]

Will this run with my ABIT Volari V8 Duo Ultra? It has 2 GPUs.

[cq842000]

I'll test again once I get my other 5970 back, then OC the CPU and tweak the memory for comparison.

[tet5uo]

Here's 3 480's and a 450.

[cq842000]

Here is what 2 HD5970s and a GTX460 look like.

Green and Red in the same shed...

[Neova]

Here are unlocked 6950s in CFX. How do you guys combine an nvidia card to this? I have my 465 GTX also but the app only sees the 2x 6950s.
