Factory Overclocked: GeForce 7600 GT

Our different flavors of 7600 GT are not as varied. We were only able to find two different clock speed configurations for this class of card coming as only slightly overclocked. The stock core speed is 560 MHz, but the majority of variants come in at either 580 or 600 MHz. As this isn't a very large difference, we decided to only test one core overclock at the high 600 MHz speed. As far as memory goes, stock clock speed is 700 MHz (giving a 1400 MHz effective data rate). We increased our stock memory speed up to 750 MHz giving us 600/750 clock speeds for our test.

Right off the bat, we see that the overclocked 7600 GT variants don't make nearly the difference as the overclocked 7900 GT cards we have. There is a slight increase in performance, but we aren't able to come anywhere near the performance of the X1900 GT. These 600/750 clocked 7600 GT cards will be in nearly direct price competition with the X1900 GT, so we can clearly not recommend them based on BF2.

With Oblivion, we still don't see a large increase in performance, and with the variance in our testing its clear that spending extra money on an overclocked 7600 GT doesn't net any dramatic gains.

Our X3: reunion numbers stand to bring home the point that has been made with our other two tests -- overclocked 7600 GT cards don't add much value and really aren't worth more money. If you're willing to spend an extra $30 for a 10% overclock, it makes even more sense to add another $30 or so and get the much faster performance offered by the X1900 GT; it doesn't make sense not to take the plunge if it's in the budget.

Clearly the 7600 GT doesn't benefit from the same advantages that the 7900 GT does when it comes to factory overclocked performance. The results in the remaining tests did not provide any new information: the roughly 10% overclock can improve performance by up to 10%, but the gap between the 7600 GT and the faster cards remains quite large.
