GPUPI 2.1 Released: 64bit and Legacy, Support for Win8, Saving Datafile

Two weeks ago we launched the new GPUPI benchmark in cooperation with Overclockers.at. The new benchmark features both CPU and GPU benchmark tests and resembles the good old SuperPI interface. The stream of new submissions followed suit and based on the feedback from the community, a new version was released three days ago.

The most important changes are of course the introduction of a 64bit and legacy version for respectively optimal performance and compatibility with older hardware configurations. We are also very pleased that GPUPI V2.1 now supports Windows 8 and up as it detects the timer used for the benchmark time-stamp. Lastly, it is now possible to save your benchmark result in a datafile and upload it later. In particular the 64bit version, in combination with Intel's latest drivers, will result in a significant performance boost. This is the reason why some community members hinted that the older version of GPUPI had better performance; an experimental v1.2 64bit beta was available.

Because the datafile offers superior security compared to a screenshot, a datafile will be MANDATORY from May 3, 2015 forward. If you have scores with GPUPI V2.0 with just a screenshot as validation proof, please submit them before this date. After May 3, no scores without the datafile will be accepted for submission. From May 3, 2015, GPUPI V2.1 will be the ONLY allowed version for submissions.

You can find the full changelog below

Changelog:

  • 64 bit version to allow 64 bit hardware and drivers to use their full potential (GPUPI_x64.exe).
  • New time measurement using QPC if available and RTC as fallback for Windows 7/XP.
  • HWBOT submissions can now be saved as data file to disk and submitted later.
  • HWBOT submission supports skipping of CPU/GPU (for detection errors) and allows erroneous submissions to be updated manually when needed. Therefor the pure manual submission of scores will be disabled again, because it's the most secure way.
  • Legacy version compiled with Visual Studio 2012 (Update 4) and CUDA toolkit 6.0. It has CUDA and OpenCL support for Windows XP and allows GeForce 200 series cards (CUDA capability 1.3) to run the benchmark. The Legacy version is slower than the default executables and should only be used if necessary!
  • Detects ~50 AMD graphics cards now (about 30 more than 2.0) including R9 300 family.
  • Automatic window resizing after a benchmark run to avoid cutting off statistics or the result. It's only done if necessary and helps especially multi GPU results.
  • Adds a watermark to invalid results to easily distinguish them from successful runs.
  • Ctrl+A now selects all text in output window.
  • Added support for UNICODE file paths for logging and configuration.
  • Hardware detection fixed for Xeon CPUs, AMD HD 7770/7750/7730 and Core 2 Duos/Quads.
  • Reduced the executable file sizes by removing unnecessary source code and several dependencies

Thanks to Mat for the swift response to the community feedback. I think this update addresses all concerns raised!

Please let us know if you have more feedback! :)

United States Bones says:

Tried to get the XP/legacy version from their site but I get a 404 error with the downlink on their page.
I'm sure it's something they'll be able to fix before long.

United Kingdom ObscureParadox says:

yup both download links are broke

Austria _mat_ says:

There is a typo in the download links (it's my fault). Find the full article with downloads here: https://www.overclockers.at/articles/gpupi-2-1 Thanks for putting this out so fast, Pieter!

France Taloken says:

Nice !

When datafile upload submission will be implemented ? (I mean on Hwbot ofc)

Need to update required version for in-bench submission too, it's say that 2.1 is not the one accepted ^^

I've updated the HWBOT benchmark version to 2.1, so from now on only submissions with 2.1 will be accepted.

The manual data file upload will start to work after the 3rd of May, when manual submission of scores is disabled. HWBOT implements it only that way.

United States Mr.Scott says:

Link for legacy is still broke.
Thanks for doing this Mat, it is appreciated. :)

United States coolhandluke41 says:

my previous ver. was 2.0 now with 2.1 (it seems like I have all installed) I can't run CPU PI ..what I'm missing ?

FlanK3r says:

good benchmark for modern CPU/GPUs btw: link for "GPUPI 2.1 - Legacy Version" download not working :(

Austria _mat_ says:

Thx, the link is fixed.

FlanK3r says:

thank you too :)

United Kingdom 8 Pack says:

More diluted focus with another Junk bench!!!

GENiEBEN says:

oi yes let's bench the same relevant x87 20yrs old bench.

Austria _mat_ says:

8 Pack said: More diluted focus with another Junk bench!!!
GPGPU using OpenCL/CUDA is a very big part of high performance computing for crunching numbers. It was about time to include something like that. And what would be better for that job than a benchmark made by an overclocker (that's me!) for overclockers that resembles SuperPi? Nothing diluted here in my opinion.

As for the "junk benchmark" you will have to elaborate on that to be taken seriously.

Spain Ximi says:

I try start on Win 7 with GPU PI 2.1 and legacy but not work , context error ... I dont know how solves it ... I try with GTX 295 .... Install HPET success.

Austria _mat_ says:

"Context error" sounds like an OpenCL initialization issue, which is almost always a driver thing. Try to install the newest drivers. Btw, sometimes the newest GeForce XP drivers are not listed at nvidia.com, but only available on the web. Have you tried selecting the CUDA version for the calculation yet?

Strunkenbold says:

Just want to say that this Benchmark is one of the best ever coded. Active development, fast bug fixing, seamless integration with hwbot. Very cool.

Agreed, was talking to a friend a long time ago and was saying that there needed to be a benchmark like this on the bot. Now that it's hear I'm glad to see it's doing so well, keep up the good work mat :)

Netherlands Oldscarface says:

Mat, can you tell me how to save a file, including the Pi calculation is done pop-up. I can only save a screen shot when I have closed the pop-up that the Pi calculation is done. Is it than still valid ?

Austria _mat_ says:

Just close the popup, it's not necessary for a valid score when submitting via data file.

Netherlands Oldscarface says:

Thanks for the feedback Mat, much appreciated. Will upload mine new score today :-)

Austria _mat_ says:

I deactivated the manual submission an hour ago so from now on it's possible to submit the data files. :)

France Strat says:

_mat_ congratz for that nice benchmark. IMHO by far the best of the recently added benches last few years :) Works flawless, light, simple and clear validation process, tweakable benchmark and so on... Keep up the good work, this is great for the community.

Austria _mat_ says:

Thank you for your kind words! It means a lot to me that you guys like it. :)
