The main benchmarking sites have already published results of the Nvidia GeForce GTX 480M (mobile Fermi). In case you missed some of them, here you have a compilation:
- Notebookcheck (Core i7 920)
- Hot Hardware (Core i7 920)
- Notebookjournal.de (Core i7 920)
- Tom’s Hardware (Core i7 820QM)
- AnandTech (Core i7 820QM)
Please note that only the last 2 ones are apples-to-apples comparisons, because the older ones are comparing the GTX 480M paired with a desktop processor against the 5870 paired with a notebook processor.
In some games the GTX 480M gets an advantage of 25 or even 30%, but in many games both cards score similar results (maybe within a 10%; the average is a 19% in favor of the GTX 480M at Tom’s Hardware).
You can configure laptops with the Nvidia GeForce GTX 480M at well known assemblers such as Xotic PC, Cizmo and others.
