HD4000: DX11 Performance
AMD's Fusion APUs have offered DX11 support for about a year now, and their graphics performance of this pair has been surprisingly good (sadly I did not have a Fusion APU available to test against). The HD4000 iGPU built into the Intel Core i7-3770K, however, is Intel's first DX11 offering. Since the HD3000 doesn't support DX11, the only thing I could compare it against was the Radeon HD5770 video card.
For the DX11 testing I used the Heaven 3.0 benchmark again, except set to DX11 and with moderate tessellation (other settings remained the same). The Aliens vs. Predator was set to medium textures, low shadows, 8x anisotropic filtering, no anti-aliasing, SSAO and shadow sampling off, and hardware tessellation, also at 1680x1050.
Here we see the HD4000 making a surprisingly good showing against the Radeon HD5770, 27% slower in the Heaven benchmark and 34% slower in Aliens vs. Predator. Next, I fired up Futuremark's 3DMark 11 benchmark and ran the four basic graphics tests. GT1 and GT2 render underwater scenes with miniature submarines moving among the elements of an undersea facility, with multiple light sources playing through the cloudy water, while GT3 and GT4 render very complex jungle scenes with many shadows and tessellated textures. For this test I selected the "Performance Level" presets and set the resolution to the same 1680x1050 I've used on the other tests.
Neither the HD4000 nor the HD5770 do very well here, but the Radeon is much faster than the HD4000 is this more strenuous test.
The best thing I can say about the HD4000 is that it's definitely quicker, actually much quicker, than the HD3000, but it still falls far short of usability for any type of 3D action gaming.
