Performance in Synthetic Benchmarks
Judging by the overall scores, there is but a small effect from overclocking the Radeon HD 3850 and no effect at all from overclocking the Radeon HD 3870. Let’s discuss individual tests that were run at higher display resolutions with 4x FSAA.
The increased clock rates help the ASUS EAH3870 TOP match the performance of the Nvidia GeForce 8800 GT 256MB in the first and third test and almost overtake the 512MB version of the latter card in the second test. The ASUS EAH3850 TOP is ahead of the GeForce 8800 GT 256MB in the second test. The average performance gain from the increased frequencies of the RV670-based cards amounts to 6-12%.
