AMD Radeon HD 7670M, codenamed “Thames XT”, is a mid-range graphics chip, announced in mid Q2 of 2011. Its core consists of six shader blocks, known as SIMD, and each of those has 80 smaller shader cores, also known as Radeon, for a total of 480 Radeon cores.
All of them operate at 600MHz. AMD has not included the Turbo clock functionality in this chip. Normally, Turbo clock is able to increase the frequency if the laptop’s cooling facilities allow for it. The chip also has a 128bit bus and is available with either GDR3 or GDDR5 memory. AMD Radeon HD 7670M supports DirectX 11, Pixel Shader 5.0, OpenCL 1.1 and OpenGL 4.2. Memory bandwidth goes up to 28.8GB/sec. Max resolutions (WxH) are 1920×1080 digital and 2048×1536 analog.
