The first chipset with PCI express 2.0 support already appeared in sale. Video card with PCI express 2.0 interface on base of g92 chips and RV670 will be available soon . Certainly, many already ask this question : will the passage to this interface give a noticeable speed increase ?
Associates have their opinion, formed on base of the seen demonstration system with PCI express 2.0 support . First , all video card series radeon HD 2600 and Radeon HD 2400 on base of RV630 and RV610 chips originally support PCI express 2.0. Associates assert that they saw a working system with PCI express 2.0 support , where the video card series radeon HD 2600/2400 showed a speed increase in separate tests, which intensively load the system bus - for example 3DMark'06.
Average speed increase compose 10%. In crossFire regime the increase will be higher . Video card with support to the functions hyperMemory and TurboCache Will also win from the passage on PCI express 2.0 .
During January 2008 , AMD will release the RV635 and RV620 chips , which will propose official support to PCI express 2.0 and DirectX 10.1, and also they will use a more contemporary 55 nm technical process. Perhaps, video card on base of these chips are better suitable for systems with PCI express 2.0 support .
