HD i7 5600U Game Requirement Analysis
Intel HD i7 5600U is the specific version of Intel HD Graphics 6000 Mobile that is integrated in the Core I7-5600U Processor.
The Broadwell Core includes support for DirectX 11.2, OpenCL 2.0 and OpenGL 4.3. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.
It equips a GPU Codenamed GT2 which offers 24 Shader Processing Units, 4 TMUs and 1 ROPs. The Central Unit Initially Runs at 300MHz and goes up to 950MHz, in Turbo Mode.
The GPU Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 1GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 800MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.
Gaming benchmarks put its performance on level with a dedicated GeForce GT 540M.
We recommend 4GB of RAM for a system with Intel HD i7 5600U.
