Iris i7 5850HQ Game Requirement Analysis

Overview
Intel Iris i7 5850HQ is the Specific Version of Intel Iris Pro Graphics 6200 Mobile that is Integrated in the Core i7-5850HQ Processor.

Architecture
The Broadwell Architecture Succeeds the Haswell Architecture and offers Faster & More Efficient Integrated Graphics. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.
The GPU Codenamed GT3-U offers 48 Shader Processing Units, 8 TMUs and 2 ROPs.

GPU
The Central Unit Initially Runs at 300MHz and goes up to 1100MHz, 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.
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 128MB 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 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 940M.

System Suggestions
Intel Iris i7 5850HQ is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
