ATI Mobility Radeon HD 3870

ATI Mobility Radeon HD 3870

The AMD ATI Mobility Radeon HD 3870 is a higher clocked Mobilty Radeon HD 3850 wich is also manufactured in 55 nm and features DirectX 10.1 support. The chip is compareable to the desktop HD 3850 and optimized for less power consumption.

The performance of the graphics card is similar to the 8800M GTS and should therefore 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 3870 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 3870 is similar to the Radeon HD 3850 (nealry similar clock speeds, same core).

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