Interface

Short Version

The type of slot the card fits in.

Long Version

There are several different types of slots that video cards can fit in. Initially there was ISA, then PCI, then AGP 1x through 8x, and now PCI-E.

Currently almost any motherboard purchased within the last 2 years will support either AGP 8x or PCI-E. While most AGP specifications were backwards compatible with one another, PCI-E is completely different and will not work with an AGP card and vice versa.

On the chips pages, this refers to the best interface the chip was designed to support. Note that chips are sometimes bridged to other interfaces using a separate bridge chip. The interface listed on the chips pages ignores does not take the use of bridge chips into account.

A complete comparison of interfaces, their specifications, and how to tell the difference is coming soon.

I think you mean the x16 connectors with only 8 lanes hooked up. These connectors are practically as good as x16 connectors because video cards really don't stress the pci-e interface very much. You might see slower performance with a turbo-cache/hypermemory card that uses the pci-e bus to communicate system memory. Aside from that there shouldn't be a noticeable difference.

Guys, I need help here. My current mother board model is an ASUS P5GC-MX/1333 - motherboard - micro ATX - i945GC. This motherboard Graphic Card slot is a PCI-e X16 type. I am considering of buying a Radeon 4870 X2 in the future,but I noticed that the card requires a PCI-e 2.0 X16 type of slot. So,my question is...is there a significant difference between PCI-e X16 and PCI-e 2.0 X16? Will my motherboard be able to support that card? Thank you for the time. =)

I would like to know if a graphic card with a PCI-e 2.0 connection fits in a PCI-e 1.0 (i think) ?
It might be a stupid question if the graphic world doesn't care about 'backwards compatibility', but if not I'd like to know
