PCI Express 2.0 to double bandwidth

Dom · Dec 16, 2004, 01:07 PM

The guardian of the PCI Express specification, the PCI Special Interest Group (PCI-SIG), has agreed to increase the bus' data rate to 5Gbps - double its current throughput.

The increase will come when the PCI-SIG finalises the next generation of the specification, expected by the end of 2005, though unlikely to appear in products much before 2007.

Three speeds were proposed for 'PCI Express 2': 5, 6 and 6.25Gbps, the latter favoured by bandwidth-hungry graphics chip and card vendors. However, the PCI-SIG's board ultimately voted in favour of the slowest of the three speeds. Not surprisingly, the vote was not unanimous, with a number of groups pushing for each speed as the one best suited to their individual technology roadmaps.

In the end the 5Gbps target was selected as the "most feasible, highest performance, backward compatible solution within the current PCI Express ecosystem", the organisation said in statement announcing the outcome of the vote.

A faster PCI Express will be needed to bring the bus into line with ever increasing Ethernet and storage interconnect speeds - not to mention the requirements of the graphics chips folks. Ethernet is expected to go to 10Gbps soon, while Serial Attached SCSI is pushing for 6Gbps.

Because we've already maxed out the current PCIe Bus speeds?

we haven't even maxed out AGP 8x speeds

people barely even have PCIe nor do they even know what it is.

Geez, cause AGP 8X is sooo slow.....

Might be so they can put more PCIe lanes?.... That's all I can think of.. >.>

It says it won't be in use till 07', I can see it being needed them. If you're into computers, you must understand that technology grows by leaps and bounds. You have to be prepared to have your current PC be obsolete within months of buying it, even if the new technology's not needed right off the bat. Technology waits for no one.

problem is that graphics cards could use a 4x agp bandwidth if they were more efficent.....
