The graphics core of the HD 4250 stems from the Mobility Radeon HD 3400 series and is therefore DirectX 10.1 capable. Because of the missing graphics memory, the performance of the card is a bit lower than of the HD 34x0. Theroretically, dedicated memory chips can be directly added to the chip, making it a dedicated graphics card (called sideport). Because of pricing it is unclear if any manufacturer will add memory to the chip.
The 3D performance is heavily depending on the used processor. With a fast Phenom II CPU for example less demanding games like Left 4 Dead or Starcraft 2 were playable in low settings and resolutions. With a slow V-Series CPU however, only old games like Doom 3 or Quake 4 should be playable. Compared to older onboad graphic chips (e.g., GMA 4500MHD), the HD 4250 is much faster. The new Intel HD Graphics in the Core ix Arrandale CPUs, offers a similar performance, but the driver support by AMD should be better.
