HD i3 6100U Game Requirement Analysis

Overview
Intel HD i3 6100U is the specific version of Intel HD Graphics 520 Mobile that is integrated in the Core i3-6100U Processor.

Architecture
The Skylake Architecture succeeds the Broadwell Architecture and aims for increased CPU and Graphics Performance, within the same Power Requirements. It includes support for DirectX 12.1, OpenCL 2.0 and OpenGL 4.4, as well as DDR4 Memory Support.
The GPU Codenamed GT2-U offers 24 Shader Processing Units, 16 TMUs and 8 ROPs.

GPU
The Central Unit Initially Runs at 300MHz and goes up to 1000MHz, in Turbo Mode.

Memory: Speed
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 933MHz for DDR3 and 1067MHz for DDR4.
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.
Best Case Scenario, expect Performance Identical to a dedicated GeForce GT 630M.

System Suggestions
Intel HD i3 6100U is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
