OverclockingSince in terms of design the Chaintech 7600GS with 512 MB onboard does not make any difference from the 256 MB version, we did not expect any surprises from overclocking. Nevertheless, the card was running stably at 475/900 MHz for the GPU/memory, respectively. The result is absolutely identical to that produced through overclocking the typical 7600GS. We found not much sense in finding additional 4-5 MHz, and it is easier to compare results at equal frequencies of video cards differing in only the video memory capacity.

To test the video cards, we used NVIDIA WHQL 84.21 drivers.
During the tests, we compared the results of the novelty versus those for Chaintech 7600GS 256 MB running at the nominal frequencies 400/800 MHz, as well as after overclocking to 475/900 MHz. The results for the 256 MB video card are depicted in dark green, and those after overclocking - in light green. The results for the Chaintech 7600GS 512 MB video card are depicted in blue, and those after overclocking - in light blue.
Our tests in the synthetic benchmarks showed that Chaintech 7600GS with 512 MB is albeit a bit but takes a lead over the 256 MB version. However, the boost is comparable to the measurement error and we can't call this a "revolution" at all. Moreover, at 3DMark'03 the regular 7600GS rushes forward for some unknown reasons.
At Half-Life 2, the picture is not changing. With the frequencies being equal both in the nominal mode and overclocked, both the video cards run abreast, and the small advantage of the 512 MB version fits within 1%.
Did you expect to see something different in DOOM3? There is a equality of results and nothing more.
At F.E.A.R., the results are completely identical. Even in the most demanding mode where we hoped to see some advantage from the added memory capacity, there is no boost.
Final Words
Well, what to say to that? At least, Chaintech 7600GS 512 MB has proved no worse than its 256 MB version. We thank Chaintech for that. But.. does it really make sense paying extra for additional memory capacity? In our view, it doesn't. With the equality of prices, the 512 MB makes sense to buy only for boasting among your friends, but you won't see any advantage in performance. On the whole, Chaintech 7600GS 512 MB is a good-quality 7600GS video card with quite regular specifications.
