TechSpot: Gigabyte GeForce GTX 570 (1280MB) Review

Nvidia's GeForce GTX 580 may be the current king of the hill, but this could change before the end of the year when AMD launches their new Radeon HD 6900 series. So with the real high-end battle still to take place Nvidia is not sitting around waiting for AMD to strike back. Instead, they are getting ready to release their second GF110-based product.

The GeForce GTX 570 should be hitting shelves shortly, featuring similar specifications to that of the GTX 480 but with a lower price at around $350. As the GeForce GTX 470 was to the GTX 480, the GTX 570 is a cut down version of the recently released GTX 580. Thermals and operating efficiency will remain much the same, as will the features. What has changed is the core configuration, operating frequencies, and memory bus width, all of which have been slightly reduced.

The GeForce GTX 570 is likely targeting the yet to be released AMD Radeon HD 6950 – which we still know little about. For now, though, let’s take a closer look at the GeForce GTX 570 we have in our hands and find out how well it performs.

Power consumption figures of the GeForce GTX 570 are roughly what we were expecting. It's interesting to note that the GTX 570 uses a similar amount of power as the much slower Radeon HD 5870 at both idle and under full load.

Of course the stand-outs here are AMD's cards, which benefit from AMD's small, more power efficient chip designs. The Radeon HD 5870 draws 50W+ less than the GTX 570 in all situations, and even the 6850 CF wavers between being slightly worse and slightly better than the GTX 570. With the architecture and process improvements the GTX 570's power consumption is in line with historically similar cards, but NVIDIA still cannot top AMD on power efficiency.

Initially we only had time to test the power consumption figures using FurMark which now appears unreliable for measuring power consumption given the changes that Nvidia has made to the GeForce GTX 500 series. When testing the GTX 580 last month we had quite a bit of trouble getting accurate readings using FurMark and therefore started to look at using games to measure power consumption and Crysis Warhead seemed like a good starting point.

The GeForce GTX 570 was 8% more efficient than the GTX 480 and while it consumed a similar amount of power to that of the GTX 470 it was considerably more power hungry than the Radeon HD 5870 using 15% more power.

PS: We measure entire system consumption and the deltas between cards.
