The Mobility Radeon HD 3200 (RS780M) is a part of AMD’s “Puma” mobile platform that also includes dual core Turion and Athlon processors. The DirectX 10-compatible integrated graphics chip features 4 ROPs, 40 unified shaders, and a 32-bit bus width. The HD 3200 in the tested HP Compaq 6735s laptop has a GPU clock speed of 500MHz and a 500MHz memory clock. The amount of shared video memory was 256MB (default) during the benchmarks.

3.7 3D Business and Gaming Graphics Performance
In older games 3D games, such as Quake 4 and F.E.A.R, the HD 3200 shows very good performance. It provides playable frame rates at medium settings.
Low Settings (640×480) – Average: 39fps
High Settings (800×600) – Average: 31fps
Maximal Settings (1024×768) – Average: 25fps
Computer at Medium Settings, Graphics at Minimum (640×480) – Average 144fps
Computer at Medium, Graphics at Medium (800×600) – Average 32fps
Computer at Medium, Graphics at High (1024×768) – Average 19fps
In newer games, such as Crysis and Company of Heroes, the Radeon HD 3200 shows lower performance. But still, you will be able to run the games.
Low Settings, 800×480 – Average 28fps
Low Settings, 1280×800 – Average 16.4fps
Company of Heroes
Lowest Settings, 1280×800 – Average 32fps
HD Video Playback
I have played two wmv video files at resolutions of 720p and 1080p on the laptop. The dedicated UVD (Unified Video Decoder) chip, that comes with the Radeon HD 3200, hardware-decodes the high definition video content, offloading the CPU. The CPU load was between 40% and %50 during 720p and 50% – %65 during 1080p playback. The video clips ran smoothly, without a glitch.
As you can see, the Mobility Radeon HD 3200 can be used for some basic 3D gaming, as well as for HD playback. That’s great for an integrated notebook GPU.
