It’s not often that we see a new graphics card get released that’s no different than its predecessor, but with the Radeon HD 6770, that’s just the case. We’re already familiar with HD 5770 performance, but let’s take a look at how this $140 card compares to its similarly-priced competition, including the recently-launched HD 6790.
It’s not that often that faithful PC gamers get a proper racing game for their platform of choice, but Dirt 2 is one of those. While it is a “console port”, there’s virtually nothing in the game that will make that point stand out. The game as a whole takes good advantage of our PC’s hardware, and it’s as challenging as it is good-looking.
Manual Run-through: The race we chose to use in Dirt 2 is the first one available in the game, as it’s easily accessible and features a lot of GPU-pounding effects that the game has become known for, such as realistic dust and water effects, a large on-looking crowd of people and fine details on and off the track. Each run-through lasts the entire two laps, which comes out to about 2.5 minutes.
Given the beefier memory bus of the HD 6790, the performance of the HD 6770 is quite impressive. I honestly expected to see a higher delta here, and this a game that does tend to scale exceptionally well with Radeon cards. Let’s see if the rest of our line-up shows similar results.
