Intel HD Graphics Mobile (Sandy Bridge) Game Requirement Analysis

Overview
Intel HD Graphics Mobile (Sandy Bridge) are Integrated Graphics in some of Intel's Budget Sandy Bridge Processors.

Architecture
The Broadwell Core includes support for DirectX 10.1 and OpenGL 3.1. Additionally, it also offers better Decoding Performance, when compared to its Predecessor.
The GPU Codenamed GT1 offers 6 Shader Processing Units, 1 TMU and 1 ROP.

GPU
The Central Unit Initially Runs at 350MHz and goes up to 1150MHz, 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 667MHz.
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 1.7GB.

Performance
Because Performance depends heavily on the Memory Bandwidth, it may vary heavily from System to System.
Performance is very limited and most modern games can't be played.

System Suggestions
Intel HD Graphics Mobile (Sandy Bridge) is best suited for resolutions up to and including 1024x768. We recommend 4GB of RAM for Optimal Performance.
