ATI Radeon HD 3670 aka RV635 Reviewed

Expreview published a preview of the ATI Radeon HD 3670 256MB aka RV635.Performance wise this card is not very impressive over Radeon HD 2600 XT.

The test result shows RV635 have a limited performance improvement.In almost all test subjects the card only outperform HD 2600XT less than 10% present which could be due to driver itself.

Two month after RV670’s debuting, AMD brings us RV635. RV635 is only a shrink version of RV630, AMD didn’t do many changes in its architecture, just adding DirectX 10.1, Shader Model 4.1 and DisplayPort support. So RV635, or HD 3670 is only a half gen evolution of HD 2600XT.

From the roadmap of AMD, we can see HD 3600 family will take the place of HD 2600 series. The price will be about 100USD. User will ask how much is the improvement? Actually not much. The average improvement is about 3%. Let’s hope it is just a another Catalyst issue, and AMD will rise the actual performance of HD 3600 series by releasing a new version of Catalyst in the near future.
