ATI played with many clock speeds and the first samples were running at 375 MHz core while memory was always fixed at 600 MHz, not 800 as was previously believed. Samples that are floating around are clocked at 400 MHz core, 600 MHz for memory and, despite its faster clock, it will be slower than 9500 Pro.
The Radeon 9500 Pro has 8 pipelines while 9600 Pro has only 4. This is the main reason for the performance decrease.
Using a high-end processor the card will give you about 11500 marks in 3dmark 2001SE and about 3500 in 3dmark03. The latter benchmark is faster than Nvidia's FX 5800 Ultra results with non tweaked drivers and at 1024x768 no Aniso or FSAA used. In Quake 3 it will result with 250+ FPS.
It is expected to be faster than Geforce FX 5600 clocked at 350/350 MHz. µ
