B.Ob. Posted December 18, 2004 Share Posted December 18, 2004 PCI Express accelerates to 5 Gbits/s "The Gen2 version of Express is also expected to add a feature that lets systems automatically scale back from 5 to the current 2.5 Gbit/s data rate based on operating characteristics. Servers might scale back if thermals exceed certain thresholds while notebooks might slow down if they are running from battery power, Pierce suggested. The anticipated move to 10 Gbit/s Ethernet and Fibre Channel and 6 Gbit/s SAS are driving the need for a faster version of Express, along with ever growing needs of digital media and graphics." Also according to Beyond3D: "Present PCI Express x16 lanes must supply up to 75W of power over the interface for the graphics card, however high end graphics boards had exceeded these power levels even before PCI Express became available, which lead to the, what looked to be rather hasty, introduction of a PCI Express graphics auxiliary power connector. The new specification calls for the x16 lane to optionally supply a total of 150W to the graphics board, which should suite all the current graphics card requirements. Our understanding is that to achieve this power will to taken away from the adjacent slot, effectively making this a two slot solution for graphics cards which also paves the way for more boards with double height cooling."
