Furthermore, the 7770M can directly support up to 6 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 7700M series also supports automatic graphics switching between the integrated GPU and discrete GPU.
The performance should be similar to the GeForce GT 650M and GT 740M and therefore in the mid-range class.įeatures of the 7770M include the new UVD3 video decoder for decoding 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 directly from the AMD GPU. As a result, general performance of the HD 7770M is expected to be slower than the desktop 7750 cards. However it but has a core clock of only 675 MHz versus the 800 MHz of the HD 7750. The design of the Radeon 7700M series has its roots to the Cape Verde chip as found, for example, on the desktop Radeon HD 7750 with 512 1D shader cores and 32 texture units. Built primarily for large laptops, the graphics card is positioned in the performance category as of 2012.
The AMD Radeon HD 7770M is a 28nm DirectX 11 graphics card based on the GCN (Graphics Core Next) architecture.
