The Radeon's have 1 billion transitors, the Nvidia's have 1.5 billion.

With 50% more die size, Nvidia generally have 5% performance lead.

They use an entirely different architecture. Clock speeds should only be compared on cards using the same chip.

Make it simple, compare both cards in the same price range, and just like they^ said.... both arch's are VERY diferent....

4850 = GTS 250
4870 = GTX 260
4890 = GTX 275
4870x2 slighty weaker that the GTX 295
