[H]ard|OCP pointed out that the might HD58xx series is now nine months old and they’ve decided to see just what has happened in the time between Catalyst 9.10 WHQL and Catalyst 10.6 WHQL.  Starting out with raw performance numbers their tests revealed an interesting fact, while performance did increase a little it generally produced about the same numbers as the original driver.  Do not draw the wrong conclusion from that as the small change is a good indicator that when the HD58xx’s hit the street, they had solid drivers behind them; not bug ridden, unoptimized drivers that needed a few revisions to age into something useful.  That meant the driver team could focus on features and basic improvements like bezel correction, Crossfire profiles and even a new generation of cards.
“Ever wonder just how much performance has improved with drivers since launch date with AMD’s ATI Radeon HD 5800 series? We did after NVIDIA’s recent driver launch, so we aimed to find out just how much AMD’s drivers have improved. We compare the launch driver, the first WHQL driver, and the current WHQL driver.”
