AMD Radeon HD 8690M.
The AMD Radeon HD 8690M (also known as the ATI Mobility Radeon HD 8690) is a DirectX 11.1 compatible graphics card for laptops. Just like the 8500M and 8700M series, it is based on the Mars chip (28nm GCN architecture), uses 384 shader cores, 24 TMUs and 8 ROPs. The core runs at 775MHz (or up to 825MHz in Boost mode) and can use GDDR5 VRAM (64bit, 1125MHz).
The performance of the Radeon HD 8690M should be between the competing GeForce GT 640M LE and GT 640M. In modern and demanding games like Far Cry 3, gameplay should run smoothly on low to medium settings.
384 shaders work with OpenCL 1.2 for general computing (6 compute units). Compared to the outdated TeraScale 2 chip, Mars-based GCN video accelerators offer the best performance on this platform.
The 8690M features a UVD3 video decoder to decode MPEG-4 AVC/H.264, VC-1, MPEG-2 and Flash formats directly from AMD GPUs. Also Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD video are now compatible.
Also, with the help of Enduro technology, the Radeon 8690M has the ability to automatically switch between integrated and discrete GPUs. This technology replaces AMD Dynamic Switchable Graphics technology and is similar to Nvidia Optimus. In addition, the 8690, using Eyefinity technology, can simultaneously display images on 2 monitors when Enduro technology is disabled.
Additional features of the 8600M series include ZeroCore technology to reduce power consumption while the screen is off, and Power Gating technology to turn off unused https://jiji.co.ke/12-engines/mitsubishi areas of the chip. PowerTune technology allows for overclocking and underclocking. For example, the chip can be overclocked while running FurMark and OCCT, and at the same time reduce the clock speed in games such as Lost Planet, Crysis or Resident Evil 5.
The built-in HD audio processor allows you to transmit high quality audio (TrueHD or DTS Master Audio) via HDMI and DisplayPort (eg for Blu-Ray video). In addition, it is now possible to output audio from multiple devices simultaneously thanks to the new Discrete Digital Multipoint Audio (DDMA) feature.
The power consumption will be almost identical or slightly less than that of the outdated HD 7670M. Ultimately, the 8690M is designed for laptops with a 13-inch screen and
