Benchmarks Real world tests of Radeon R9 M290X vs 290X

3DMark Vantage Graphics Industry standard benchmark that tests DirectX 10 GPU performance

Just like 3DMark 11, you can see the score in both presets is ahead of all the other setups here thanks to that very strong overclock.

3DMark06 Industry standard benchmark that tests DirectX 9 GPU performance

3DMark’s texel fill test is one of a handful of tests where the 290 and 290X are actually separated by as much as the theoretical performance difference implies they should be.

BioShock Infinite 1920 x 1080 - Ultra preset + DX11 (DDOF)

Radeon R9 M290X
46.8 fps
Radeon R9 290X
94.9 fps
Notice that not one of them actually averaged over 900 MHz (though Skyrim got very close) and Bioshock Infinite actually was the slowest at 821 MHz.
