The AMD ATI Radeon HD 4225 (sometimes also ATI Mobility Radeon HD 4225 called) is an onboard (shared Memory) graphics chip in the RS880M chipset. It is based on the HD 3400 graphics core and features the UVD 2 video engine to decode HD videos (Avivo HD - can decode two HD streams simultaneously). Compared to the HD 4200 and 4250, the 4225 offers a worse performance due to the slow clock speed.
The UVD 2 video engine is able to decode HD videos (MPEG-2, H.264, and VC-1) in all stages and allows the fluent playback of HD videos (e.g. Blu-ray) with a relative low CPU utilization (called Avivo HD). The HD 3200 was the first onboard graphics card that allows the fluent playback of Blu-ray videos. The UVD 2 in the HD 4225 supports the decoding of two video stream and therefore got a full Blu-Ray support.
The graphics core of the HD 4225 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. Because of pricing it is unclear if any manufacturer will add memory to the chip.
Still older games like Doom 3 or Quake 4 should be barly playable.
The AMD ATI Mobility Radeon HD 4100 or just Radeon 4100 is an integrated graphics card (shared memory) for laptops. Compared to the HD 4200, the HD 4100 probably features a lower clock speed (and perhaps also some features are stripped down). According to differencebetween.net the clock rate is just 350MHz and therefore below the low power HD 4225.

Game Benchmarks
The following benchmarks stem from our benchmarks of review laptops. The performance depends on the used graphics memory, clock rate, processor, system settings, drivers, and operating systems. So the results don't have to be representative for all laptops with this GPU. For detailed information on the benchmark results, click on the fps number.
