AMD HD6790 Review
3D Mark Vantage
At stock it clearly isn't a great performer in Vantage. Although the P score isn't bad we can't imagine there is anyone still running 1280x1024. With the detail pushed up it's a fair bit behind the slightly pricier HD6850. Overclocking it does unleash a fair bit of performance though and it's much close to the HD6850.
3D Mark 11
It's a different story in the shader intensive 3D Mark 11 though. Most modern games make good use of the DirectX shaders to give more realistic graphics and the HD6790 is really struggling. The first card we've tested to score beneath 1000 points in the X test. Even overclocking doesn't help much as the cut-down architecture is limiting things.
