HKEPC web-site has had an opportunity to compare performance of the GeForce Go 7300 against the GeForce Go 6200. Given that overall specifications of the GeForce Go 7300 and 6200 are approximately similar, performance difference is mainly conditioned by efficiency of the architecture.

According to benchmarks by HKEPC, the GeForce Go 7300 is 9% faster than the competitor in 3DMark2001 and 3DMark03, but managed to leave the predecessor behind by 17% in 3DMark05. In Doom III game performance difference between the parts is about 10%, while in Battlefield 2 and Half-Life 2 the GeForce Go 7300 is faster compared to the GeForce Go 6200 by 14% and 11% respectively.
