Radeon HD 4890 side-by-side with GeForce GTX 275

The results are fairly clear here. When it comes to compute and low-end gaming, the 4890 takes the cake. However, when you're pushing the maximums at 2560 x 1600 with full effects, the greater pixel fill, filter and memory bandwidth figures begin to add up. But, only for gaming. On compute, the ATI Radeon HD 4890 wins hands down at 1.36 Teraflops, and 1.44 with the 4890-OC. Anybody looking to buy a high-end graphics card could do a lot worse than either of these cards, both available for sub-$260, with the -OC running a slight premium closer to $300.

The story is too old to be commented.
