View Full Version : Open CL score

02-11-2018, 08:18 PM

The OpenCL score is dependent on several things ?
With the same OC for the CPU, I have a much lower score with a GTX 1080 than a GTX 1070 (the version of the Nvidia driver is not the same)

GTX 1070


GTX 1080

Hi tistou77

It depends a bit on GPU OC, a lot on whether you run open CL on the CPU at the same time or not, can also depend on the Nvidia driver version...

Thanks ;)

How run (or know) Open CL on the CPU ?

There is a special driver you can download...on this page https://software.intel.com/en-us/articles/opencl-drivers

Ah ok, I did not have it for the test with the gtx 1070, so the score difference is not at this level
This is another thing

Thanks ;)

Nobody noticed a decline for the Open CL score from 1 or 2 months ?
That of the 1070, I had it at the end of December

My guess: most likely from those two "famous" security holes and their Windows patches.
I too noticed a lower score with my GTX 1080 Ti.
Given that I really don't care that much about scores, I didn't give it a second thought.

That's what I thought too, and having not benchmarked since late December, I do not know if it's related to Windows patch and maybe with the 1070, I'll have had lower scores

But it's mostly to be sure, because with a 1070 have 90k and 70k with a 1080, I'm puzzled :D

If anyone with a 1080 could test
Even if it's not the same OC CPU, etc ... the scores should give an idea

Not 1080 but close.
Maybe it helps

Thank you for the test
Your Windows is up to date with the latest CUs ?

Odd that I have 2 times less

I think it's a problem with the graphic card, in GPU-Z memory is only 1251mhz instead of 5005 mhz

Try reinstalling your Nvidia driver and test again

02-14-2018, 04:59 PM
Already tested, with other drivers too
Tested with an old bios, the memory is at 5005mhz, but the type of memory is not recognized, and the Open CL score is even lower (driver reinstalled too)

I'm thinking it must be some bios or Windows update, the 1080 seems to be under performing, I don't have a 1070 at home to test

1080 with CPU opencl
Titan Xp
T Xp with CPU opencl

it will be normal 1251 mhz, in fact

I'm thinking it must be some bios or Windows update, the 1080 seems to be under performing, I don't have a 1070 at home to test

Thanks so much for your tests ;)
Same as me

The problem would be the Microsoft patch since January then

Thanks so much :)

If it's the patch it sure kicked the 1080 right in the huevos on this test

Have you install the latest Management Engine firmware ?

02-15-2018, 03:16 PM
No I haven't, the system has been setting unused for a couple months, I can update everything and test again if it helps in any way.
The 1080 is an early release FTW, I believe newer versions have a little faster memory, I tested at default no overclock applied

02-15-2018, 04:14 PM
It's really weird, I tested with a Windows 10 with no update (16299.15) and I have the same result
The bios is 1003 (no new microcode) and I just updated the firmware Management Engine

Really a pity I did not do an Open CL test just before removing the 1070

Since you have the same results as me with the 1080, it must be normal
I just find it odd that the 1070 had a better score

Or it's just the driver Nvidia (another difference in the tests)

Thanks for your help

02-15-2018, 05:00 PM
In fact, I think it's the same driver Nvidia (according to the date)...

These scores are good for a 1080 ?
