Coming from X-Bit Labs is a review on the NVIDIA GeForce 7900 GT 256MB PCIe graphics card. Finer 90nm production technology allowed NVIDIA not just to improve the technical specs of its flagship product dramatically. They also managed speed up its younger brother, which has become faster than the legendary GeForce 7800 GTX. And the latter is famous for having arrived at the right time and market segment and thus turning into a great success. We are going to find out whether the $299 graphics solution will be able to win the leader's title from the 10-month old buddy. This time NVIDIA didn't disable any execution units in the GT suffixed product, so frequency is the single difference between the GeForce 7900 GT and the more expensive GTX.
NVIDIA GeForce 7900 GT 256MB PCI-E Review
The GeForce 7900 GT features 24 pixel processors, 24 texture mapping units
(TMUs), 8 vertex processors, and 16 raster operators (ROPs). The developer
recommends 450MHz GPU and 1320MHz memory frequencies for this product which,
again, are higher than the frequencies of the company's best product of less
than a year ago. And unlike the GeForce 7900 GTX, the GeForce 7900 GT uses a
unique PCB design, developed almost from scratch. The new card is shorter than
the GeForce 7800 because the GPU and memory chips have moved along with their
accompanying components.
No doubt that the new NVIDIA graphics card positioned
for the $299 price segment is an extremely successful solution. GeForce 7900 GT
inherited all the good features of the GeForce 7800 GTX, but at the same time
turned out less complex, less expensive and much more economical thanks to the
new G71 GPU. The newcomer proved just great during our real-time test session.
In most tasks it outperformed Radeon X1800 XL and in some of them it competed on
equal terms with a more powerful Radeon X1800 XT. Of course, 24 TMUs it features
helped a lot to achieve this success.
This feature combined with about
48W of power consumption, which is much lower than by GeForce 7800 GT and Radeon
X1800 XL and excellent overclocking potential give all every right to award
GeForce 7900 GT with a title of the best $299 graphics card in the today's
market. So, if NVIDIA's
partners manage to establish regular large quantity supplies of the new GeForce
7900 GT based products, a lot of users will most likely prefer the newcomers to
the Radeon X1800 GTO and XL based solutions. And in some cases, they may even
give up Radeon X1800 XT board...
