    PCIe Speed test

    While snooping around AMD forums I found this: http://developer.amd.com/GPU/ATISTRE...s/default.aspx

    It is a synthetic benchmark that is supposed to find the PCIe bandwidth from the CPU to GPU and from the GPU to CPU.

    I'm not sure how much communication is actually happening in say a game or GPGPU app, but it should give some indication of performance.

    I found this a couple of days ago myself. It crashes my ATI Catalyst driver on the last test. The driver has to recover every time. I do like that it lets you know the CPU-to-GPU and GPU-to-CPU performance. I'm trying to break 1GB/s on the GPU-CPU bandwidth. Heres my output (before it crashes):

    Core i7 2600K| 16GB G.Skill@2133mhz XMP | ASUS P8Z77-V Pro | Coolermaster Hyper 212 | Seasonic 750W PSU | Diamond HD 4870 512mb Crossfire| Fatality X-Fi | Samsung 840 Pro 128GB SSD | RAID0 2xWD 750GB Caviar Blacks |TV Wonder HD 650 PCIe

    Interesting app, I wonder how accurate the results are...

    DrSpanky is spankin wingless in GPU -> CPU, we need to see more single core GPU results & multi core GPU results as well as more CF/SLI results to compare.

    The only operating systems officially supported are Linux 64-bit and XP 32-bit.

    The test also crashes my display driver after 67108864 bytes.

    Anyway here is my output:

    hi everyone, I used to have exactly the same issue with my bandwidth GPU->CPU like wingless and firestrider. And it disappeared when I updated my ATI driver to the 9.11 version. I hope it's going to be the same for you guys.

    see you

    ps : i have a 4870 1Go
