GeForce 9800 GX2


We knew that Nvidia's flagship GeForce 8800 Ultra's days were numbered after the graphics manufacturer released the GeForce 8800 GT late last year. A single GeForce 8800 GT can't outperform an Ultra, but two GTs will, and the two cards can be had for less than the price of a single Ultra. AMD also added pressure on the Ultra with the release of its dual-GPU ATI Radeon HD 3870 X2. Nvidia has today responded with a new flagship card, the GeForce 9800 GX2.

The GeForce 9800 GX2 promises top performance thanks to its two onboard GeForce 9800 GPUs, featuring a combined total of 256 processing cores clocked at 1.5GHz. In comparison, the GeForce 8800 Ultra has only 128 processing cores at the same clock speed. The GX2 also comes with an equally large price tag, with an estimated retail price ranging from $599 to $649. Our XFX GeForce 9800 GX2 came with Company of Heroes and an "I'm gaming, Do not disturb" doorknob hanger.

It's easiest to think of the GeForce 9800 GX2 as SLI on a single card. The card has two stacked printed circuit boards, one for each GPU, similar to the design of the GeForce 7950 GX2. However, unlike the 7950, the 9800 GX2 comes encased in a sleek plastic enclosure. The two GPUs won't double the frame rates over a single chip due to SLI overhead, but should show decent gains ranging between 1 and 2x depending on the application. The card has 1GB of memory with 512MB dedicated to each chip. The GX2 supports PCI Expresss 2.0 and DirectX 10. ATI's latest cards support DirectX 10.1, but we haven't seen any games that take advantage of it yet.

Nvidia has confirmed that you will be able to run two GeForce 9800 GX2 cards together for Quad SLI, but the company isn't letting any publications post quad-GPU numbers until next week, when its PC system partners make their Quad SLI announcements.

Our XFX GeForce 9800 GX2 has HDMI and two dual-link DVI-I connectors. The dual-link DVI connectors can handle high-resolution monitors, and can also run VGA monitors using analog adaptors. HDMI output connectors have become more important now that video cards are capable of accelerating HD video playback. The GX2 has a SPDIF audio input connector on the top of the card to supply the audio feed from the motherboard or an external graphics card for HDMI output.

A performance monster like the GeForce 9800 GX2 also comes with hefty power requirements. Nvidia recommends using a 580W power supply with a single card and 850W for two GX2s running in SLI. XFX recommends 630W or more for a single GX2 and 680W or more for an SLI configuration. You also need to make sure that the power supply has the necessary six- and eight-pin power connectors for the card. The power input connectors can be a little snug--we had to snap off some of the plastic between the two connectors in order to get our Targas power supply plugs to fit into the card.

Power-conscious users might be interested in the GeForce 9800 GX2's new HybridPower feature that lets you switch between integrated graphics and the GX2 depending on the graphics workload. The switch allows users to save power while running normal desktop applications that don't need the video card's processing power. The feature currently only works with HybridPower-enabled motherboards with integrated GeForce graphics.

Judging by the specifications, we expected the XFX GeForce 9800 GX2 to perform similarly to a GeForce 8800 GTX or Ultra SLI system. We currently don't have any GeForce 8800 Ultra cards, but our dual GeForce 8800 GTX configuration, currently selling for close to $800, should be a formidable challenge. We also tossed in an ATI Radeon HD 3870 to see how another dual-GPU card compares, and a GeForce 8800 GT SLI setup to see how one of Nvidia's best SLI offerings stacks up to the newest 9800. We had to fall back to Windows XP SP2 in Crysis and Unreal Tournament 3 due to irregular driver performance in Vista.

Me likey and I like that you can switch between integrated and card gfx, that always bugs me (not saving power but prolonging life of the components ).

Ill get one of these when they're old news and noone else wants one, thats when I'll be able to afford it lol.

[shortie]

it so amazing i would like it badly

[noonzascript]

should stick with the 8800 :/ 9800 GX2 sounds too hardcore for gaming

[Darkcityxx]

ive got two 8800's so i think ill be ok for while

[Watercycle]

haha nice
