ATI Mobility Radeon HD 3850

ATI Mobility Radeon HD 3850

The AMD ATI Mobility Radeon HD 3850 is a slower clocked desktop HD 3850 and manufactured in 55 nm. It supports DirectX 10.1 in hardware and also features the Avivo HD video engine to help the CPU decode videos. The card is intended to be used in large laptops.


The performance of the graphics card is between the GeForce 8700M GT and the 8800M GTS. The ATI Mobility Radeon HD 4650 of the successor generation performed similar but with a much lower power consumption. Therefore, the performance should be sufficient for DirectX 9 games in medium to high details (see games list beyond).

The RV670 chip has 64 5-dimensional unified shaders with 16 ROPs, 16 TMUs, and 32 TAUs.

The Avivo HD video engine helps the cpu in decoding HD videos (MPEG-2, H.264, VC-1). The HD 3850 houses the UVD+ (Unified Video Decoder) that is capable of decoding MPEG-2, H.265/AVC, and VC-1 nearly fully. The UVD2 in the HD 4000 generation is capable of full bitstream decoding and two video streams can be decoded at once (which UVD+ can not).

Compared to desktop graphics cards, the HD 3850 is similar to the Radeon HD 3850 but features a much lower clock speed, leading to a worse performance.

The power consumption of the HD 3800 series lies between 35-55 Watt.

Gaming Performance

This benchmarks were conducted with an AMD Puma platform (with a Turion 64 Ultra at 2.4 GHz). Therefore, a fast Core 2 Duo should perform better.

Crysis: 1024x768, medium: 24 fps -> barely playable
World in Conflict: 1024x768, Medium: 30 fps -> playable
Medal of Honor: Airborne: 1024x768, High: 35 fps -> playable
