HD4600: DX11 performance
I investigated the performance of the new HD4600 integrated GPU in my original Core i7-4770K review. My conclusion: much better, but still no match for even the cheapest discrete graphics card. Since the Core i7-4770K and Core i5-4430 have the same iGPU, with the only difference being that the maximum clock speed of the former is slightly higher (1250MHz vs. 1100MHz), I thought it would be interesting to compare their performance. Let’s start with Unigine Heaven:
Heaven 3.0 settings: 1680×1050, moderate tessellation, medium shaders, no anti-aliasing, and 4x anisotropic filtering
The 4430 gives up only about 9% to the 4770K. Moving on to Aliens vs. Predator:
AvP Settings: 1680×1050, medium textures, low shadows, advanced shadows off, SSAO off, no anti-aliasing, 8x anisotropic filtering
Here, the difference is even smaller: the 4430 is only about 6% slower than the 4770K.
Last, let’s take a look at 3DMark 11‘s GT1 through GT4 tests. These tests render underwater and jungle scenes with tessellation and multiple light sources, with distance blur and other features added with post-processing passes. For these tests I selected the “Performance” presets and set the resolution to 1680×1050.
The GT1 and GT2 render underwater scenes with lots of cloudy water, moving submarines with light sources, and large structures seen murkily through the haze. The 4430 give up 12.5% in GT1 and 13.5% in GT2.
Again, we see that the 4430 is nipping at the heels of the 4770K.
Last, let’s take a look at the Lost Planet benchmark.
And the 4430 turns in exactly the same performance as the twice-as-costly 4770K. I guess they really are using the same iGPU.
But nobody would actually play any of these games with the iGPU. They’d use a real video card. Let’s consider this in the next section…
