Radeon HD 7690 – Notebookcheck
The AMD Radeon HD 7690M is a fast middle class graphics card for laptops in 2011. It is basically a renamed Radeon HD 6770M with 100MHz higher memory clock speed. Therefore, it is still built in 40nm and supports DirectX11. According to AMD there is also a DDR3 version available which is based on the (faster clocked?) Thames-XTX chip.
The 480 Stream processors are still based on the 5D architecture similar to the 5000 series. Therefore, the number of shaders is not comparable to the 1D cores of current Nvidia GPUs. The Tessellation performance should be improved (like the desktop 6800 series) with the new cards. The Stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. With the later two the cores can also be used for general computations like transcoding videos.
The 3D performance is slightly better than the GeForce GT 555M and therefore positioned in the upper middle class (in 2011). Demanding games like Anno 2070 or Skyrim can only be played in medium detail settings and lower resolutions. Some games like Battlefield 3 may even only run in low detail settings. Older games hovever like Call of Duty: Black Ops are playable with all settings maxed.
The new UVD3 video decoder supports the decoding of MPEG-4 AVC/H.264, VC-1, MPEG-2, Flash and now also Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos on the graphics card.
Furthermore, the HD 7600M series integrates a HD audio controller to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g. for Blu-Ray videos).
The AMD HD3D Technology offers support for Blu-Ray 3D and 3D displays (integrated and external). However, the solution is not as mature as Nvidias 3D Vision.
Thanks to Eyefinity the graphics chip is able to theoretically drive up to 5 monitors simultaneously. However, this only works if the laptop features enough DisplayPort outputs.
The power consumption of the chip should be similar to the Mobility Radeon HD 5770 and therefore suited for 15″ laptops and up.
