SLI Is Coming: Time To Analyze PCI Express

Taped PCI Express X16 Running Up To X1

This is how a PCIe graphics card with only 8 workable lanes looks.

Here is the same card with only 4 lanes.

Even though PCIe is not intended to run at x2, we tried it anyways - it works without problems.

In case of x2 PCIe, front and back side have to be taped differently - accuracy is important here.

Last but not least, x1 PCI Express. It is definitely too slow for a graphics card, but in order to get a complete picture we included those results as well.
