OpenCL support

Hello.

Are there some special requirements for GPU-Z (v0.5.0) in order to identify the OpenCL capabilities of a card?

I use it in a Win7 x64 system with a mobility ATI HD-4670.

The installed drivers support OpenCL and GPU Caps Viewer 1.9.5 has no problem identifying it and run its tests.

No GPU-Z version up to now could identify it in my system and wonder where it's getting thrown off.

Any ideas?

Thanks.

You need to install the stream sdk ( or APP as it's now known) for it to show up in cpu-z.

Certainly with 5xxx and 6xxx cards anyway.

My 9800GT was the same. The Open CL box would never show a check mark. GpuZ is picky with some cards and combos.. I wouldn't worry about it lol. The 10.12 OCL package is all you need.

10.12 OCLs


Here is an Open Cl bench if you want to test some more.

Thanks for the link.
I had already picked up ratGPU but never tried it.

On first try, it hung my system.

Second time I read its notes. No ATI HD-4xxx support. It claims it misses some required functionality. There goes ratGPU...

I suspect it has to do with the lack of Image Support in my card.
GPU-Z and some other software I try to get to work are probably looking for it and they just don't say.
Your new card probably has it that's why it's working.

Check it with GPU Caps Viewer.

Tools->Full XML Report
In the OpenCL section I have:
- CL_DEVICE_IMAGE_SUPPORT: NO

You must have a 'YES' there.

Too bad I don't have the luxury of changing to a better card in the laptop.

Thanks again.

Did you try installing this also?

Yes of course. v2.3

Without it there wouldn't be any OpenCL identified by anybody.

OpenCL detection also fails with Cedar 5470 which supports the extension above.

Is your laptop also an "Intel HD + ATI hybrid" like mine?
Probably GPU-Z checks the capabilities of the Intel GPU instead of the ATI GPU?

its not a question of your GPU supporting OpenCL - its more about what PROGRAMS support OpenCL - AFAIK, there are only a small handful of programs that fully utilise OpenCL on ATi/AMD cards.

then theres the group of people who think that installing OpenCL gives them an Extra 200+ points in benchmarks and some 'notable' performance increases in games but who knows. Performance is more of a subjective thing, and at the end of the day it only makes a small difference which some will notice and some wont
(hence the term subjective - just because there are no "knowns." There are things we know that we know. There are known unknowns. That is to say there are things that we now know we don't know. But there are also unknown unknowns. There are things we don't know we don't know)

As you sayed a handfull of programs support OpenCL, an on small HD4000 card as good as on HD5000.
GPU-Z does display OpenCL as unsupported on dv6 Notebook with AMD Processor and Mobility Radeon HD4500/HD5100 Seriese GPU, with CCC 11.1 ocl installed, while OpenCL Applications run nicely on it. Wold be nice if it wold be corrected in future versions of GPU-Z.
Since not all GPUs suport OpenCL 1.1, it would be nice to get the Supported OpenCL Version displayed somewhere (I know the ist not much space left, without making the App bigger) .

Sorry for being late to respond. I've been busy lately.

@StephanM
My system is not a hybrid. Just an ATI card in it.

@FreedomEclipse
I don't much care for benchmarks or play games. But I use some graphics applications and would like to utilize some addons for them that take advantage of the GPU for rendering. It's either OpenCL or get an nVidia card for my laptop which of course I can't do.
Some of them work in spite of GPU-Z, some work badly and some don't.

It would be nice if GPU-Z could point out what capabilities it thinks are out of spec.

gpuz really just tries to initialize an opencl context on the graphics device, if that works -> yes
if not -> no

could you post a screenshot of some opencl diag tool that shows the device name ? maybe gpuz is looking for the wrong device

Btw for Rendering ratGPU is very bad. Try Luxrender Instead it should get soon the smallluxGPU feature which runs fine even on HD4000 Cards.


Here I've seen that even with Nvidia CUDA GPU-Z doesn't show OpenCL.

Here I've seen that even with Nvidia CUDA GPU-Z doesn't show OpenCL.

that was the info i needed:
CL_DEVICE_NAME => RV710
GPU-Z GPU => M92

that's why GPU-Z didn't find opencl. it looked for a device called M92 whereas the actual device is called RV710.

I changed that in the attached build, please give it a try.

kaenas, can you post a gpu-z screenshot please?

The M96 mod worked just fine. Thanks a bunch.

Should we expect these changes in an official forthcoming version or should we stick with these modded versions?

Thanks again for taking care of this.

Would be bumping this by posting, but after I updated to 270.61, this happened:


When I was still using the 266.58 drivers OpenCL was checked, but now it isn't.
