AMD Radeon HD 7770 And 7750 Review: Familiar Speed, Less Power
By

In the pages that follow, you’ll see the Radeon HD 7770 and 7750 tested against six other graphics boards. These six were chosen based on an initial price estimate AMD gave us between $99 and $199 for its two new cards. In retrospect, I would have rather benchmarked a GeForce GTS 450 against the Radeon HD 7750 instead of a GeForce GTX 560 Ti up top. Also, it would have been nice to have a Radeon HD 6790 in here. That card wasn’t available for testing though, so we have the venerable Juniper-based 5770.

Also, pay particular attention to the GeForce GTX 460. The card we’re using for comparison is a 1 GB board with a 256-bit bus. As you probably already know, Nvidia sells a 768 MB version of the card. Now, however, it’s also taking advantage of the GPU’s ability to address different memory ICs by shipping a 1 GB model on a 192-bit memory bus. If you’re not paying close attention and end up with that configuration, performance will be lower than the 256-bit card benchmarked here. It’s a sneaky move, but if you buy from a vendor that lists detailed specifications, you won’t get unknowingly duped.
