We've posted an "ATI Stream Power Toy" page:


The first such "toy" on this page is a PCIeSpeedTest utility that tried to measure the PCIe bandwidth on your system. We've found this useful when trying to see what the PCIe IO bandwidth is in a system and how it might affect the overall performance.

This is a synthetic benchmark so your actualy real world performance may vary. But, its intent is to try to extract as much bandwidth out of PCIe link in each direction as possible.

This is offered as an unsupported, but hopefully semi-useful tool for all of you. :-) Suggestions for other "toys" you'd like to see can be sent to streamdeveloper@amd.com. No promises, but we'll see what we can do.

If you run this and want to share your peak results, we'd be interested in seeing it on this thread! Post your peak results in each direction along with your motherboard, CPU and GPU configurations.
