Raytracing, KriBiBench, WAV
Falling just behind the Intel offering. The performance deficit has more to do with the 925XE's higher clock speed than anything untoward with NVIDIA's implementation, I feel. Athlon 64 reigns supreme.
The performance deviation in KribiBench cannot be explained away by a less-than 1% clockspeed difference. The results were repeatable time after time.
Using an HT-optimised WAV encoder also shows a slight deviation between results. Nothing to get excited about, however.
