Call of Duty: Modern Warfare 2
Each of the Radeon HD 5670 cards delivers an excellent speed in both 720p and 1080p mode. Their average performance is roughly similar to that of the GeForce GT 240 GDDR5 but the latter has a higher bottom speed, even though this has no effect on the gamer’s comfort. So, these cards allow playing Modern Warfare 2 on a big screen but we must note that even the senior Redwood (RV830) based card cannot beat the oldie Radeon HD 4770. They are not much faster than the Radeon HD 4670, either.
The Radeon HD 5570 is far from impressive. Equipped with slow memory and working at a reduced core frequency, it cannot deliver a playable frame rate even in the 720p mode although its average frame rate is good. As for the Radeon HD 5450, you can start modern games on it but you cannot play: the frame rate of 15-25 fps makes the process far from enjoyable. Thus, the Cedar is only limited to decoding high-definition video.
Left 4 Dead 2
The in-game benchmarking tools are more accurate than Fraps but cannot report the bottom frame rate.
We don’t have any bottom speed info, but the overall picture is the same as in the previous game: the Radeon HD 5670 copes with both HD-ready and full-HD modes, the tiny factory overclocking of the Gigabyte card giving it a tiny advantage. Take note that the GeForce GT 240 GDDR5 falls behind AMD’s solutions at 1920x1080.
There are differences, though. The Radeon HD 5570 feels confident in this game. Although somewhat slower than the old Radeon HD 4670, it allows playing with enough of comfort. The Radeon HD 5450 is poor, again. The gameplay is jerky even at 1360x768 and the first-person shooter is reduced to a kind of a turn-based strategy as soon as there appear enemies in the scene.
Resident Evil 5
The Radeon HD 5670 cards turn in good results for their class although both are inferior to the Radeon HD 4770. The gameplay is smooth at both 1360x768 and 1920x1080. The Radeon HD 5570 is almost as good as the Radeon HD 5570 and slightly inferior to the GeForce GT 240 GDDR5, but we’d recommend to turn FSAA off for the 1080p mode because the game begins to lag noticeably in some scenes.
This won’t do for the cards based on the junior GPU in the Radeon HD 5000 series. You have to lower the level of detail, losing some of the game’s visual impact. So, if you are going to play more or less seriously on your HTPC, you may want to choose a more advanced graphics card.
Street Fighter IV
The game has such low system requirements that you can enjoy it fully even on a Radeon HD 5450 in HD-ready mode, i.e. at 1360x768. As for the faster cards, the Radeon HD 5670 is almost as fast as the Radeon HD 4770 and beats the GeForce GT 240 GDDR5 at 1920x1080. The most compact Radeon HD 5570 model competes with the Radeon HD 4670 and outperforms the GeForce GT 220 at 1360x768.
