Intel HD Graphics 4200 Mobile are integrated graphics in the ULV Haswell Desktop processors.
Their performance depends on the processor they are integrated on, as the latter defines the Base and Boost Clock, as well as on the SYSTEM RAM, which defines the operating memory clock, and whether the GPU accesses a 64-bit or 128-bit memory interface.
Best case scenario, the Intel HD Graphics 4200 Desktop perform slightly above Intel HD 4000 Graphics, though some variants actually perform worse and so most modern demanding games will have to be played with the lowest settings, while a few aren't even playable.
