In terms of overall gaming performance, the graphical capabilities of the HD i7 3840QM and the HD i7 3920XM are equal.

Both the HD i7 3840QM and the HD i7 3920XM were released at the same time, so are likely to be quite similar.

The HD i7 3840QM and the HD i7 3920XM have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the HD i7 3840QM and the HD i7 3920XM are the same, which means the HD i7 3840QM and the HD i7 3920XM have equal limitations when it comes to graphical data transfer.

Both the HD i7 3840QM and the HD i7 3920XM have 16 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the HD i7 3840QM is 83 and by the HD i7 3920XM is 51. Knowing that the shader performance of the HD i7 3840QM is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The HD i7 3840QM requires 45 Watts to run but there is no entry for the HD i7 3920XM.

GPU Mini Review

Mini ReviewN/AHD i7 3920XM is a specific version of the Intel HD Graphics 4000 that comes with the CPU 'Core i7-3920XM 4-Core 2.9GHz'.
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 1300MHz (the max), if necessary.
It's the fastest variant of the Intel HD Graphics 4000 but 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.
