UHD Graphics 620 Game Requirement Analysis

Overview
Intel UHD Graphics 620 are integrated graphics in some of Intel's Kaby Lake mobile processors.

Architecture
The Kaby Lake architecture succeeds the Skylake architecture and aims for increased CPU and graphics performance, via the same power requirements. It includes support for DirectX 12.1, OpenCL 2.1 and OpenGL 4.6.
The GPU solution, codenamed GT2, offers 192 shader processing units (SPU), 24 TMUs and 3 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.
Depending on whether or not the system's RAM is dual-channelled, 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 525M.

System Suggestions
Intel UHD Graphics 620 is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for optimal performance.
