This makes the Iris Pro even faster than AMDs Radeon HD 8650G and the fastest integrated GPU of 2013. Thanks to the fast eDRAM memory, the average performance of the Iris Pro is only about 15 percent behind the dedicated mid-range cards GeForce GT 650M and GT 750M (DDR3 versions). It also features an improved decoder for 4K videos and the fast Quick Sync encoder. The Iris Pro supports DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. In comparison to the HD 4000, the graphics core has been modified extensively. Depending on the processor model, the base and turbo clock rates may differ (usually up to 1200 - 1300 MHz), resulting in varying graphics performance between CPU models. It represents the highest configuration of the integrated graphics unit (40 execution units) and also has an additional eDRAM cache (128 MB on-package, 77 mm², 102 GB/s). The base clock can be automatically overclocked using Turbo Boost technology. The Intel Iris Pro Graphics 5200 (GT3 + eDRAM), also called the HD Graphics 5200, is a processor graphics card that is included in some of the Haswell processors of 2013 (e.g.
