Obviously, the test result is out of our expectation. The temperature of 55nm GTX260 is higher than that of 65nm, under loaded and idle mode. This is really confusing, and we suspect if the cooler of GTX260 is shrinked. When we take the cooler apart, the answer finally comes out.







◆ The Overclocking performance of 55nm GeForce GTX260

The benchmark platform is the same as we state before, and we find 55nm GTX260 can work at 720MHz core clock steadily, improved by 145MHz. If old version cooler is adopted, I guess the core clock would be higher, and the memory interface will improve from 999MHz to 1130MHz.

55nm gtx260 seems to be just a cheaper knock off of 65nm version with a cheaper cooler. nothing special about it. overclock will probably only going to get you 50Mhz more than the 65nm version.

having got a 65nm myself. i don't see myself upgrading. would probably bump speeds up to 675/1453/1151 for gtx280 performance as seen on the Fudzilla benchmark.
