Zotac GeForce 9800 GT 512 MB (GeForce 9800 GT, 512 MB)

Roundup: Mainstream Graphics Cards From ATI And Nvidia

ATI and Nvidia are both very aware of where their respective strengths lie, so it's almost humorous that, for a story like this one, it's difficult to get access to many of Nvidia's mainstream offerings. The interest is usually in the company's more powerful products, which sell for more than $150. If you were wondering why there are more ATI cards in this roundup, now you know.

Thanks to Zotac, we were able to procure one GeForce-based test card that comes in around $100 and doesn't have to be shielded from faster competition. This tweaked version of the GeForce 9800 GT is able to keep up with ATI's Radeon HD 4770. Its overall performance lags only 1.1% behind the 40 nm Radeon HD 4770, leaving the Radeon HD 4670 and Radeon HD 4830 far behind.

Zotac does not adhere to reference clock rates, and thereby affords its GeForce 9800 GT some extra muscle. Its GPU clocks in at 660 MHz instead of 600 MHz, and the shaders run at 1,600 MHz instead of 1,512 MHz. The memory clock rate remains unaltered at 900 MHz. This card supports DirectX 10 and comes equipped with 512 MB of GDDR3 RAM. The graphics chip is labeled as G92b, is based on 55 nm process technology, and is a direct successor to the GeForce 8800 GT.

The fan is fairly narrow, enabling this card to fit in a single expansion slot. For an Nvidia card with a low-profile cooler, its temperature readings are typical: 58° C for 2D, and 87° C for 3D under heavy load. By comparison to competing cards, the Zotac GeForce 9800 GT’s power-consumption levels are relatively high, in part because it doesn’t reduce clock speeds in 2D mode—the card consumed 173 W in 2D mode and 292 W in heavy 3D mode. Noise levels measure at a quiet 36.3 dB(A) in 2D mode, but climb to a clearly audible 46.8 dB(A) under heavy 3D loads.

This card is nearly 9.1” long (23 cm) and requires a six-pin PCIe power connector. You’ll find splitter cables in the retail package for both power and component video, plus a DVI-to-HDMI adapter and an internal SPDIF cable to carry digital audio output. You’ll also find XIII Century: Death of Glory in the box as well.
