Conclusion - MSI and Colorful offer integrated HDMI output
Thanks to continually improving drivers, ATI’s Radeon HD 2900 XT is finally closing the performance gap to the Geforce 8800 GTS 320 under Windows XP. The price gap is another matter, though, with the powerful ATI card still costing about €110 more. MSI compensates for the higher price by including a component output cable for HDTV, various adapters, ViVo functionality, and the game Half Life: Episode 2, which was only just released.
When running in a Crossfire configuration, the Radeon HD 2900 XT gains around 21.4 percent performance across our benchmark suite. A tandem of HD 2600 Pro cards can even achieve a 41.3 percent performance boost. With games that are specifically programmed to take advantage of multiple GPUs, a 40 to 85 percent performance increase should not be a problem, either. While the 2600 Pro Crossfire setup sells at a reasonable price of €164, the 2900 XT tandem is much too expensive for a gaming card at €690. For a little less money, you could just as well choose the quieter Geforce 8800 GTX, which is just as fast, or go for the faster 8800 Ultra.
The Radeon HD 2600 XT Zalman and the Radeon HD 2600 XT IceQ Turbo, both made by HIS, offer the same value for money. If you overclocked the Zalman version to the same speeds as the IceQ card, it would theoretically win the price/performance comparison – but you would be voiding your warranty. The IceQ version is factory overclocked, meaning the higher speeds are guaranteed by the manufacturer and covered in the warranty. Since the IceQ version only costs €6 more at present, we recommend choosing this card. However, if you only have room for a single-slot solution, you should consider the Zalman model. Both cards sport relatively quiet fans with noise levels of 38 to 39db (A).
MSI’s 8600 GTS comes with excellent equipment. The Diamond Plus version sports an integrated HDMI port and a large bundle. Its powerful fan is loud, the card’s 3D performance very good. Using MSI’s driver and the D.O.T. overclocking feature it contains, you can increase the clock speeds, and thus performance, by an additional 2 to 10 percent. The second card to sport a “real”, i.e. integrated HDMI port, is made by Colorful. This card also offers the best value for money in this roundup.
Recommendations
ATI
For its good performance and quiet cooling solution, we recommend the HIS Radeon HD 2600 XT IceQ Turbo.
Nvidia
If you can live with the higher noise level of this card’s fan, we recommend MSI’s Geforce 8600 GTS Diamond Plus. The card sports an integrated HDMI interface, offers outstanding performance, and comes with a generous bundle.
Budget Pick
Colorful’s Geforce 8600 GT HD receives our budget recommendation, as it offers good 3D performance and an on-board HDMI interfaces for little money.
First ! e vai!
"The HIS card only comes with DVI connectors, which makes dual-link a sensible choice for the 1920 resolution."
Uh. No, it really doesn't.
The HDMI(1.2 and below) type A connector is equivalent to
a single-link DVI-D connector; the adaptor is purely
mechanical. Dual-link DVI is equivalent to the HDMI type
B connector, which is largely unused (although I have
hopes, because HDMI 1.3 type B can do 680MPix/s).
1920x1080p/60 fits quite nicely through the bandwidth
limit (165MHz) of an HDMI 1.2 type A connector, and
equally well through a single-link DVI connector -
as you can tell by the multitude of single-link DVI
24" 1920x1200@60Hz monitors on the market.
Dual-link DVI would give you 48bpp colour support at
1920x1080, but that's irrelevant if only a single link
is being used, via an HDMI adaptor. Also, the DVI
connector is perfectly capable of transmitting the
audio component of HDMI (the audio component uses the
same signal wires as the video), if it can be routed
to the card. Whether the content permits the audio to
be routed without HDCP is beyond my expertise.
Also, at the risk of testing my mathematical abilities:
"In Windows XP, the performance delta between the two cards in cumulative frame rate is now less than 20fps (Geforce 8800GTS 1878.9 fps, Radeon HD 2900 XT 1809.6 fps)."
That sounds like "less than 70fps" to me (not that it
makes much difference, obviously - they *are* close.)
