Furthermore, the 8670M can directly support up to 2 connected monitors using Eyefinity Technology if Enduro is disabled. Called Enduro, the technology supersedes AMD's Dynamic Switchable Graphics and is similar to Nvidia's Optimus. The 8600M series also supports automatic graphics switching between the integrated GPU and discrete GPU. Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos are now compatible as well. Compared to old TeraScale 2 chips, the GCN-based Mars architecture offers improved performance in this framework.įeatures of the 8670M include video decoding via UVD3 for decoding MPEG-4 AVC/H.264, VC-1, MPEG-2, and Flash directly from the AMD GPU. The 384 shaders can be used with OpenCL 1.2 for general-purpose calculations (as 6 compute units). Current and demanding games like Far Cry 3 will run fluently only in low resolutions and detail settings. The performance of the Radeon HD 8670M is similar to the old Radeon HD 6750M and GeForce GT 630M. The core is clocked at 775 MHz (825 MHz Boost) and can access a DDR3 VRAM (64 Bit, 1000 MHz). Just like the 8500M and 8700M series, it is based on the Mars chip (28nm GCN architecture) with 384 shader cores, 24 TMUs, and 8 ROPs. The AMD Radeon HD 8670M (sometimes known as the ATI Mobility Radeon HD 8670) is a DirectX 11.1 graphics card for laptops.
