ATI Mobility Radeon HD 2400 vs vs Vivante GC800

ATI Mobility Radeon HD 2400

This is a DirectX 10 graphic card from ATI and direct competitor to the NVIDIA GeForce 8400M GS graphic card for laptops. This would mean that the card is able to represent all modern DirectX 9 games in medium resolutions and without Antialiasing without motion interruptions. Demanding DirectX 10 games may only run in low settings and resolutions.

Due to the Avivo HD videoengine  the Chip accelerates HD Video like HD DVD, Blu-ray (Video Decoder for H.264/AVC, VC-1, MPEG-1, MPEG-2, MPEG-4/DivX Video Codecs). Furthermore PowerPlay 7.0 brings longer battery runtimes. Furthermore, ATI Mobility Radeon HD 2400 is certified for Windows Vista (for the Aero user interface).

Technically, the chip owns 40 stream processors which are able to manage vertex-, geometric or pixelshader operations. Therefore DirectX 10.0 and Shader Model 4.0 are supported. To be mentioned is also the 256 bit wide ringbus.

Compared to the Destkop HD 2400 Pro the Mobility version has a lower clock speed (450 versus 525 Mhz core speed) and is, therefore, a bit slower.

Vivante GC800

The Vivante GC800 is an integrated graphics card for ARM based (e.g. Rockchip RK291x) and MIPS based (e.g. Actions ATM701x) SoCs. It offers a single VEC-4 (or in other words four VEC-1) unified shaders and supports OpenGL ES 2.0 (optional ES 3.0), OpenGL 2.0, OpenVG 1.1, DirectX 9_3 (optional) and OpenCL 1.2 (optional). The clock rate can be choosen between 315 and 575 MHz in 40nm designs and up to 800 MHz in 28nm designs.
