How well does the GeForce 9800 GTX+ overclock? We set off to answer that question today by finding the limit of our card and running a number of benchmarks to see just how well it does. Our original review showed that the GeForce 9800 GTX+ was 10.4% faster than the Radeon HD 4850, so any gains should be money in the bank. Read on to see how NVIDIA's first 55nm GPU overclocks on the GeForce 9800 GTX+ video card!
The highest settings we could get stable with the GeForce 9800 GTX+ were 855MHz on the core and 2200MHz on the shaders. This is 55MHz higher on the core and 175MHz higher on the shaders than what we could reach on the old 65nm backed G92 cores. This is roughly 6% more on the core and 8% more on the shaders, which is significant, but nothing over the top. Usually with die shrinks overclocking performance stays close to the same, even more so when no major architecture changes are made. It should be noted that the memory overclocked better on the GeForce 9800 GTX+ and it seems NVIDIA has moved over to Hynix branded GDDR3 memory ICs. The GDDR3 memory IC's on the new GeForce 9800 GTX+ card were Hynix H5RS5223CFR-N2C, which are rated 1200 MHz (GDDR3-2400) 0.8NS with 1.5V. These are the same memory IC's that were found on the GeForce GTX 280 cards we reviewed last week.
