Is that a clock-to-clock comprasion? Or its just the XFX setting their cards to a higher clock as default?
Only because i cant guess, what can make this much of a difference (sometimes even 10%) between theoretically identical cards.
The quick 3DMark test I ran was using my own Sapphire 7970 clocked at the default
XFX speeds vs default
Sapphire speeds (before 'Boost clock'); I own no XFX card to compare them at identical clocks. The listed XFX just has a higher default clock speed, though Sapphire comes close on the linked card if 'Boost Clock' kicks in. I never used Boost so I have no idea how well that works (if it's anything like AMD Turbo it sucks) so I just went off stock speeds.
Using the Boost Clock speeds for Sapphire though;
Graphics Score (Points) 3524.0 (+157)
Graphics Test 1 (FPS) 17.8 (+0.8)
Graphics Test 2 (FPS) 13.4 (+1.2)
Combined Test (FPS) 7.46 (+0.36)
