S.T.A.L.K.E.R.: Call of Pripyat & Overclocking Results

S.T.A.L.K.E.R.: Call of Pripyat Results

Performance for the GTX 660 on S.T.A.L.K.E.R.: Call of Pripyat was fairly close to AMD's Radeon HD 7870, with the exception of the 1920 x 1200 resolution, No AA, Day Run, where the GTX 660 was able to score a significant win.

For the most part, the GTX 660 was better than the HD 7870 at 1920 x 1200 resolution, while the HD 7870 caught up and slightly outscored it at the 2560 x 1650 resolution, with the exception when anti-aliasing was turned off, i.e., No AA.

For our custom cards, ASUS maintained a small lead of about 2-3%, while there wasn't anything to separate Gigabyte and MSI. 




Overclocking Results

Overclocking on the GTX 660 was fairly successful and followed a similar pattern to the rest of our benchmarks. ASUS was again the best performer, with core speeds raised to 1160MHz and memory to 6240MHz DDR, increasing its performance by about 4% on 3DMark 11's Performance preset, and by 6% on Extreme compared to its default settings. Compared to the reference card, this was about 11%-13% better than the its default speeds.

Efforts with Gigabyte and MSI both produced similar results, with each improving on their default scores by about 4%. Gigabyte's final core overclock was 1130MHz, with MSI's slightly higher at 1138MHz. For memory overclocking, MSI was again a bit better, as it was able to go to 6208MHz DDR compared to 6160MHz DDR for Gigabyte. As a result, MSI's overclocking performance was marginally better, outperforming Gigabyte's best OC scores by about 1%.

Interestingly, despite their limited success in overclocking, they couldn't best the overclocking capabilities of the AMD Radeon HD 7870. But that shouldn't be too much of a concern seeing the huge price difference in favor of the GeForce GTX 660 cards.
