That isn’t enough, though, to convince us that the GTS 450 is worth the cash, especially when the ATI Radeon HD 5770 costs a similar amount and is significantly faster in most of our benchmarks. That’s slightly higher than the 233W required by the HD 5770, but lower than the GTX 460 and a far cry from Nvidia’s earlier Fermi parts. Power consumption wasn’t too bad, either: when placed in our test rig, which consists of a Gigabyte GA-X58A-UD7 motherboard, Intel Core i7-980X processor and 6GB of RAM, the machine drew 258W at peak. The Nvidia card improved in the more demanding Stalker benchmark, scoring 41fps to the HD 5770’s 36ps, which is some consolation.Īt least it performed well in other areas, with an idle temperature of 30 degrees and a peak of 71 degrees proving nothing to worry about. In DiRT 2 at 1,920 x 1,080 and High quality settings, the ATI card scored 63fps to the GTS 450’s 41fps. Moreover, the GTS 450 could only manage a playable frame rate in our Very High-quality test at the reduced resolution of 1,366 x 768, where the HD 5770 returned playable results in the same benchmark at 1,600 x 900. A score of 33fps in our 1,920 x 1,080 High quality Crysis benchmark sounds good, but its price rival, the ATI Radeon HD 5770, ran through the same test 6fps faster. Clock speeds may be high, but the reduced number of stream processors means performance isn’t stellar.
