Resently we posted an article comparing Catalyst 8.8 with 8.7, in which we mainly focused on their behavior on DirectX. Providing us a furthur view, the OpenGL news site Geek3D posted an article titled ‘ATI Catalyst 8.8 vs 8.7: OpenGL Performance Drop’ which is based on HD 3870.
CPU: C2D E8400
Motherboard: EVGA 790i Ultra SLI
RAM: 2GB DDR3 1333MHz
VGA Card: HD 3870 @ reference clock
Operation: Windows XP
As the chart shows, HD 3870 face a performance drop on OpenGL when using Catalyst 8.8. All benchmark drop except for Furmark.
However, the increased score on Furmark is also strange. In spite of the HD 3870, HD 4870′s score on furmark actually dropped dramatically(drop by around 50%) in our review. And in our forum, some readers also posted the same issue. We wonder why different cards will achieve different scores on the same driver?
