For this comparison we were provided with two notebooks - in the NVIDIA corner we have the Sager NP9860, using a 3.2GHz Prescott (P4-E), 1GB of RAM and a GeForce 6800 Go clocked at 300/300 with a 256-bit memory bus.

Our GeForce 6800 Go testbed
In ATI's corner we have an unnamed M28 launch partner (we can't mention who until M28 is launched in about 2 weeks) using a 3.4GHz Prescott (P4-E), 1GB of RAM and a M28 clocked at 400/400 with a 256-bit memory bus.
The systems are configured as closely as possible, with the CPU clock speed being a slight advantage in ATI's favor. But given the fact that most of our benchmarks will be GPU limited and the CPU clock speed advantage is around 6%, don't expect it to tilt things too far in ATI's favor.
1) There is no point of reference. Where are the benchmarks for a radeon 9700 Mobility or Radeon 9800 Mobility? We have no idea how much faster these things are than existing mobility parts "
Agreed. I am about to buy a ThinkPad T42p with a 128MB ATI Mobility FireFL T2, and don't know what I'll be passing up.
