So what is your result for speed up? and what is the application you have. Also I think matrix multiplication is a very GPU friendly calculation because of it’s highly paralellizable. So this result is a little disappointing. I often hear people get 20-100 times speed up. Most of the time, there is no speed up at all. and the best result for speed up is 5 times (cpu_time/gpu_time) for a matrix of size 30k*16k( this is the biggest size of matrix I can fit into a 16GB memory of GPU). To make comparison more fair, I also included data transfer time to and from GPU in the gpu_time, because this is the overhead of using GPU. I think compare GPU to single thread CPU is cheating. The OpenBLAS thread count default on this server is 16 threads. I think both libraries are highly optimized and should be a fair comparison. For CPU I used OpenBLAS library, and CuBLAS for the GPU. I ran my experiment on a server that has a Intel Gold 6148 CPU, which has 20 cores at 2.40 GHz frequency, and a GPU of NVIDIA V100 16GB memory. So I ran a matrix multiplication to do the comparison. But I don’t know what kind of speed up is expected. Each test simulates a different kind of gaming and tests out things like frame rates, physics simulations, rendering capabilities, and other GPU-focused tasks.Hi, I heard the amazing things about GPU and how much faster it can beat CPU. You’ll be taken through three major tests: Ice Storm, Cloud Gate, and Fire Strike. Hands down, 3DMark is our favorite benchmark software as it’s beautiful to watch. Once you’ve done that, launch 3Dmark and start the test. We suggest taking a moment to shut down all the apps that might generation such popups (such as killing the ituneshelper.exe in Task Manager). This means any kind of system tray popup notification or any “iTunes has a new version available!” type popup will force you to restart the test sequence. ![]() Any pop-up or focus-stealing intrusion during the process will turn off the benchmark. To use it, visit the 3Dmark page, download the demo (although they encourage you to use Steam, Valve’s game/software distribution network, to download the demo, you can use the Mirror button to download it directly without a Steam account).Īfter downloading and installing 3Dmark, there’s really only one thing you need to do before running your tests. If you’re curious what the primary differences are between the free and the pay version, the pay version allows you to run the sequence of benchmarks in any order (or opt to run only one of the benchmarks) as well as the ability to loop tests for stress testing and run an additional extreme test.įor light use where you just want to see how much better your old system was compared to your new, the free version is more than powerful enough. ![]() Not only is it cross platform, but there is a free desktop version, and you can compare your results to other machines across the world also using 3DMark to perform benchmarks. In fact, the GPU benchmark tool that we used for the Kindle Fire review, 3DMark, is also a cross platform tool. And, in the case of simply wanting to benchmark your old GPU against your new GPU, there are really simple solutions. Is there an easy way for a computer literate but not super technical guy like myself to do the same thing easily? Thanks!Īlthough benchmarking can become extremely technical and time consuming, it certainly doesn’t have to be. I noticed you guys benchmarked the GPUs of the Kindle Fires you recently reviewed. My only real motivation is so that I can sit back and say “Hah! It was so worth paying all that money for a video card upgrade!” while looking at the new score. I’ve ordered a new video card for my desktop and, while I’m waiting, I’d like to perform some benchmarks. Is there a simple way to perform a comparison between GPU performances (say, before and after a major video card upgrade)? Read on as we explain how. A lot of benchmarks are rather arcane and filled with technical parameters and jargon.
