Did rampant leaking push the launch dates of the ATI Radeon HD 4890 and the NVIDIA GeForce GTX 275 up to today? Who knows! But one thing’s for certain, the cards are here. We’ve gone and sifted through the benchmarks from a cross-section of the sites after the jump and have crunched their numbers to give you the four metrics you really care about:

Avg.* FPS:

GeForce GTX 275: 63.53
Radeon HD 4890: 62.70

Price/Performance:

GeForce GTX 275: $3.91**
Radeon HD 4890: $3.97

Avg. Consumption (idle/load):

GeForce GTX 275: 172/293.66W
Radeon HD 4890: 189/277W

Avg. Temperature (idle/load):

GeForce GTX 275: 46/81.5C
Radeon HD 4890: 46/69C

* If you’re wondering, the average frame rates represent the performance of 21 different benchmarks run on 1680×1050, 1920×1200 and 2560×1600 resolutions. I think that fairly distributes benchmark bias. On average, the GTX 275 commanded a 3-4 FPS lead at 1680×1050 and 1920×1200, but the 4890 skipped ahead by an average of 3 FPS at 2560.

** There’s one small problem with the GeForce GTX 275: It may have an MSRP of $249, but at the time of writing, I can guarantee you won’t find this card anywhere. The Radeon HD 4890, on the other hand, is available at every etailer I checked. Our prices are, naturally, based on Newegg.
