The Intel HD Graphics 4600 (GT2) is a processor graphics card that is included in some of the Haswell processors of 2013 (4th generation core). The base clock can be automatically overclocked using Turbo Boost technology. Depending on the processor model, the base and turbo clock rate may differ greatly resulting in different graphics performance.
In comparison to the HD 4000, the graphics core has been modified in several details. The GPU supports DirectX 11.1, OpenCL 1.2 und OpenGL 4.0. It also features an improved decoder for 4K videos and the fast Quick Sync encoder.
According to Intel-benchmarks in 3DMark 11, the HD Graphics 4600 will be up to 60 percent faster than the previous HD 4000. This performance boost is achieved by architectural improvements and an increased number of execution units: The GT2 version integrates 20 so-called EUs, compared to 16 EUs for the old HD 4000. Thus, the HD 4600 would not only match some dedicated GPUs such as the GeForce GT 630M, but also compete with the fastest integrated AMD-GPUs like the Radeon HD 8650G.
Due to the 22nm 3D Tri-Gate production process, the power consumption should be relatively low. The HD Graphics 4600 will initially be used in quad-core models of the 47-watt class.
