Performance, Availability, Conclusions
Performance of the Go 7900 GTX and GS is a bit of mystery. Unlike the launch of the Go 7800 GTX, the documentation accompanying the Go 7900 does not have any benchmarks performed by NVIDIA. The press package showed a total of 3 benchmarks, two of them weren’t even Go 7900 benchmarks, and the last was comparing the Go 7900 GTX to the ATI Mobility Radeon X1800XT which didn’t disclose the scores in 3DMark 05 and 3DMark 06.

NVIDIA GeForce Go 7900 GTX and Go 7900 GS Preview - Mobile 5
Go 7900 GTX 30% faster than Radeon Mobility X1800XT in 3DMark 06.
Go 7900 GTX 14% faster than Radeon Mobility X1800XT in 3DMark 05.

The unanswered question here is why NVIDIA did not provide any of their own tests. Instead they relied on 3rd party tests to illustrate their points, of which only one featured the Go 7900 GTX. Even though we don’t know exactly how the new Go 7900 GTX GPUs will perform, I suspect we can expect a 10% performance jump compared to the Go 7800 GTX similar to the jump from 7800 GTX to 7900 GTX on desktops. Personally, I was interested to see how the compromises on the Go 7900 GS affected performance, but we’re all going to have to wait for retail products it seems before we see any test results.
Final Thoughts
By improving their manufacturing process on mobile GPUs from 11 micron to 9 micron, NVIDIA was able to put higher clocks on the Go 7900 GTX without increasing power consumption. This should mean that NVIDIA has yet another top performing mobile GPU on their hands. Without a Radeon Mobility X1800 GPU on the market, NVIDIA currently has free roam in the high-end gamer laptop market.
I don’t have much of an impression of the Go 7900 GS since we have no indication how it will perform. It would be a real gem of a GPU though with lower power consumption and yet have good performance when needed.
We eagerly await test units so we can see how these new mobile GPUs really stack up.

As with the launch of the Go 7800 GTX a few months back, the Go 7900 GTX will be available immediately through DELL and Toshiba, with other vendors sometime after. Currently we do not have any pricing information, but expect to pay a premium for this new technology initially.
