HD i7 3820QM Game Requirement Analysis
HD i7 3820QM is a specific version of the Intel HD Graphics 4000 that comes with the CPU 'Core i7-3820QM 4-Core 2.7GHz'.
The new features include DirectX 11 and Tessellation support though using them might not be a very good idea since even strong fast-middle-class GPUs struggle with them.
The core-clock is initially set at 650MHz and will go to up to 1250MHz, if necessary.
The performance depends a lot on the driver support and benchmarks indicate that the most demanding games, such as Metro 2033 can only be played at the lowest settings. Deus Ex 3, for example, ran fine at high settings but other demanding games such as Crysis 2 and Batman: Arkham City only ran fluently at medium settings.
