AMD last week released a 1GB variant of its popular Radeon HD 6950 graphics card, and to see how the performance would be throttled with the GDDR cut, we benchmarked both versions with the latest Catalyst 11.1 driver. Does the 1GB card and its $20 savings prove too hard to ignore, or should the 2GB still be the one to scoop up?
One of the more popular Internet memes for the past couple of years has been, “Can it run Crysis?”, but as soon as Metro 2033 launched, that’s a meme that should have died. Metro 2033 is without question one of the beefiest games on the market, and though it supports DirectX 11, it’s almost a feature worth ignoring, because the extent you’ll need to go to in order to see playable framerates isn’t likely going to be worth it.
Manual Run-through: The level we use for testing is part of chapter 4, called “Child”, where we must follow a linear path through multiple corridors until we reach our end point, which takes a total of about 90 seconds. Please note that due to the reason mentioned above, we test this game in DX10 mode, as DX11 simply isn’t that realistic from a performance standpoint.
Being that Metro 2033 is the most “hardcore” game we test with from a technical standpoint, I had expected to see the 2GB card come well ahead of the 1GB model here, but that again wasn’t the case. Despite sharing the same clock speeds, the 1GB consistently places ahead of the 2GB.
