Keep in mind that different driver versions and CPUs may also impact the benchmarks. However, in our benchmarks the card positioned itself sometimes even on a level of the higher clocked Radeon HD 6730M (same chip). The 3D performance should be identical to the Radeon HD 6650M.
With the later two the cores can also be used for general computations like transcoding videos. The Stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. The Tessellation performance should be improved (like the desktop 6800 series) with the new cards. Therefore, the number of shaders is not comparable to the 1D cores of current Nvidia GPUs. The 480 Stream processors should be still based on the 'old' 5D architecture similar to the 5000 series.
According to AMD there are two versions available, a slower clocked Thames-Pro with GDDR5 memory and a faster clocked Thames-XT with DDR4 memory. Therefore, it supports DirectX11 and is still manufactured in 40nm. The AMD Radeon HD 7670M is a middle class graphics card for laptops and based on the same chip as the Radeon HD 6650M.
