Intel Core i7-5775C With Iris Pro Graphics Review: Broadwell For Desktops
Low-Res Gaming: DirectX and OpenGL
For our next set of tests, we moved on to some in-game benchmarking with Crysis (DirectX), Bioshock Infinite (DirectX) and Enemy Territory: Quake Wars (OpenGL). When testing processors with some games, we drop the resolution and reduce all of the in-game graphical options to their minimum values to isolate CPU and memory performance as much as possible. However, the in-game effects, which control the level of detail for the games' physics engines and particle systems, are left at their maximum values, since these actually place some load on the CPU rather than GPU.

The results in our low-res game tests are all over the map, for various reasons. The Core i7-5775C's performance in Crysis is strong, most likely due to Broadwell's architectural enhancements and the processor's huge eDRAM cache. In the ET:QW test, however, performance falls in-line with many of our other tests, where the higher-clocked processors prevail. For these two tests, a discrete graphics card was installed to level the playing field.
In this Bioshock benchmark, we're back on integrated graphics, and as you can see, the Iris Pro 6200 series engine has no trouble dispatching all of the other platforms, which also used integrated graphics.
