Galaxy GTX 275 Overclocked Review

This past year has been exciting in the video card market. We have seen simultaneous launches from both AMD/ATI and Nvidia countering each others new products. This past April, the two heavyweights put forward the HD 4890 and the GTX 275 in the ring to go toe-to-toe with each other. In this review we compare the overclocked versions against each other.

Although not a new architecture, the GTX 275 is essentially an upgrade over the GTX 260+ just as the HD 4890 is faster than the older HD 4870. The GTX 275 is basically one half of the dual-GPU GTX 295 video card but has faster clocks compared to Nvidia’s flagship.

The GTX 275 features the same number of shaders (240) as the GTX 285,  but with a slightly cut-down memory interface which is 448-bit wide vs. the GTX 285’s 512-bit interface. The GTX 275 comes with 896 MB of video memory, while the GTX 285 comes with 1GB and the GTX 295 comes with 1792 MB (896 MB per GPU).

The card that we are looking at today comes from Galaxy, and it is overclocked out of the box.

The clock speeds on the Galaxy GTX 275 OC (over the reference clocks are):

• 650 MHz core (vs. 633 MHz)
• 1475 MHz shader (vs. 1404 MHz)
• 1200 MHz memory (vs. 1134 MHz)

Let’s take a look at our test subject.

In this test we will be comparing this GTX 275 to the Diamond HD 4890 XOC which is also overclocked out of the box with clocks of 925 Mhz core/4200 MHz memory up from its reference clocks of 850 MHz core/3900 MHz memory. We did a review of the Diamond HD 4890 XOC here & here.
