Iris Graphics 550 Mobile Game Requirement Analysis
Intel Iris Graphics 550 Mobile are Integrated Graphics in some of Intel's Skylake Mobile Processors.
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 GT3-E offers 48 Shader Processing Units, 8 TMUs and 2 ROPs.
The Central Unit Initially Runs at 350MHz and goes up to 1050MHz, in Turbo Mode.
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.
An addition to the Iris Graphics is the access to a L4 Cache of 64MB eDRAM which further increases the Memory Performance.
Memory: Frame Buffer
The GPU Shares the System's RAM which varies according to the System. The GPU may reserve up to 1.7GB.
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 930M.
Intel Iris Graphics 550 Mobile is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
