Compared to dedicated graphics cards, the HD620 should be positioned between a GeForce 910M and 920M from Nvidia. That means only some less demanding recent games like Farming Simulator 17 run fluently in low detail settings (see below for gaming benchmarks). The exact performance of the HD Graphics 620 depends on various factors like 元 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model but is very similar to the old HD Graphics 520 GPU. Due to its lack of dedicated graphics memory or eDRAM cache, the HD 620 has to access the main memory (2x 64bit DDR3/DDR4). This "GT2" version of the Kaby Lake GPU is clocked at up to 1050 MHz (depending on the CPU model). The Intel HD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake generation. Intel HD Graphics 620 ► remove from comparison The HD Graphics 4600 can be found on dual- and quad-core Haswell models in the 37 - 57 Watt TDP range. Due to the 22nm 3D Tri-Gate production process, power consumption should be relatively low. Thus, the HD 4600 not only matches some dedicated GPUs such as the GeForce GT 620M/630M, but also competes with the fastest integrated AMD GPUs like the Radeon HD 8650G. This performance boost is achieved by architectural improvements and an increased number of execution units: The GT2 version integrates 20 EUs, compared to 16 EUs for the old HD 4000. In our gaming benchmarks, however, the improvement was only about 30 percent. According to Intel benchmarks in 3DMark 11, the HD Graphics 4600 will be up to 60 percent faster than the previous HD 4000. It also features an improved decoder for 4K videos and the fast Quick Sync encoder. The GPU 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 greatly resulting in varying graphics performance between CPU models. The base clock can be automatically overclocked using Turbo Boost technology. The Intel HD Graphics 4600 (GT2) is a processor graphics card included in some of the Haswell processors of 2013.
