Launched mid-October, the Radeon HD 5770s are a less powerful version of the Radeon HD 5800s. They keep the eyecatching DirectX 11 compatibility and moderate power consumption but what about gaming performance? Are they better or worse than the older generation?

Size, noise and heat generation

The Radeon HD 5770 uses a short PCB (printed circuit board, on which the components are soldered) – only 21 cm (8.3"). Yet the stock cooler is a double decker. While it's bulkier, it keeps the card’s sound down to a very acceptable level in 2D.

At idle, we measured 39.8 dB(A) with the graphics chip at 41°C: the card was barely warm and the fan noise was perceptible but quite unobtrusive. In use, the GPU doesn’t get very hot, not going above 84°C, but with noise levels at 56.2 dB(A). So the fan is really noisy during gaming and could disturb the people around you (in a living room, say).

Energy consumption

The 5770 retains the advances in energy management of the 5800 series. At idle, our wattmeter read 84 W, and it topped out at only 230 W during our intense 3D test. These numbers are for the entire computer, not just the graphics card. Only a single 6-pin PCI-E power connector is needed.

Gaming performance

The card is meant mostly for owners of monitors with average definition (1680 x 1050). With such resolutions it allows you to run games with the texture filters on and enable all detail settings on most games. You will have to back off on graphics options for certain very power-hungry games (ArmA 2, BattleForge, Crysis). So the card’s performance is well down on the older Radeon HD 4870 1GB.

The first set of results is with World in Conflict: Soviet Assault. At 1680 x 1050 with filters activated, the 5770 scored an average framerate of 32 fps, compared to 36 fps for the 4870. With ArmA 2, still at 1680 but without filters, the average framerate was 39 fps for the 5770 and 45 fps for the 4870. With Tom Clancy’s H.A.W.X, at 1680 x 1050 + texture filters, the 5770 scored 52 fps and the 4870 61 fps.

Pros

  • Reduced power consumption in 2D and 3D
  • Low noise at idle
  • DirectX 11 compatibility

Cons

  • 3D performance – you’ll want to reduce certain details in power-hungry games
  • No stereoscopic 3D
  • Noisy in 3D

Conclusion

If you don’t absolutely need to play with all graphics options set to the maximum and you don’t play every day, this model will do.
