Intel HD Graphics 5300 Mobile Game Requirement Analysis

Overview
Intel HD Graphics 5300 Mobile are Integrated Graphics in some of Intel's ULV Broadwell Processors.

Architecture
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.
The GPU Codenamed GT2 offers 24 Shader Processing Units, 4 TMUs and 1 ROP.

GPU
The Central Unit Initially Runs at 300MHz and goes up to 900MHz, in Turbo Mode.

Memory
The Operating Memory Clock depends at which speed the System's RAM is running and which Memory Type is installed and is ultimately limited by the highest operating speed that the Processor supports. In this case, it is 800MHz.
Depending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface.

Memory: Frame Buffer
The GPU Shares the System's RAM which varies according to the System. The GPU may reserve up to 2GB.

Performance
Because Performance depends heavily on the Memory Bandwidth, it may vary heavily from System to System.
Best Case Scenario, expect Performance Identical to a dedicated GeForce GT 420M.

System Suggestions
Intel HD Graphics 5300 Mobile is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
