3DMark Vantage is the latest 3DMark test from Futuremark. Traditionally, 3DMark focused on GPU performance but with 3DMark 2006 and Vantage, Futuremark has given more attention to the CPU. 3DMark Vantage features two CPU tests that focus on either artificial intelligence calculations or physics calculations. 3DMark 2006 features two CPU physics simulations of differing quality. These tests scale incredibly well with cores so the more threads available the higher the score.
It seems pretty standard that AMD graphic cards perform slightly better in 3DMark 2006 and slightly worse in 3DMark Vantage when compared to Nvidia graphic cards of similar caliber. Not surprisingly, the two cards trade blows through the tests and are overpowered by the HD 4870x2.
