The PCI successor is just around the corner

The PCI successor is just around the corner

For graphics cards, the PCI slot simply does not offer enough speed and features to be competitive with the AGP slot. The 'Arapahoe Work Group' now wants to change this and has submitted a draft of the successor to PCI-SIG.

PCI-SIG has been 'managing' the PCI bus for ten years, so since 1992. The Arapahoe Work Group consists of large companies such as Compaq and Hewlett-Packard, Microsoft, Intel, Dell and IBM. The first specifications of the 3GIO (Third Generation I/O) have now been submitted to the aforementioned PCI-SGI. If the PCI-SIG top approves the drafts, all 740 member companies will have 60 days to review the specifications. The final name of the new slot will be 'PCI Express'. The first versions should have a bandwidth of up to 200 MBytes per second. That is a considerable increase compared to the current 133 Mbyte/s. Later, up to 1.25 Gbytes per second should be able to be achieved. The appearance will also change compared to the current PCI bus. The number of pins will be reduced from 84 to 40. This means that the 'small' slot should also be able to be installed in smaller devices. The first PCI Express 1.0 standard should be ready in the second quarter of this year. The first workstations with the new slot will then be manufactured at the end of 2003. The large graphics chip manufacturers ATI and nVidia are also interested in PCI Express.
