Only in a best case scenario the performance is similar to the GeForce GT 635M. Therefore, due to the micro stuttering and performance problems, Dual Graphics may impose more problems than bring performance gains. In some games the performance may even degrade by 10-15% compared to using only the APU graphics card.

The performance of the Dual Graphics solution depends greatly on the driver support for the used games. Therefore the combination also suffers from micro stuttering (different spaces between two images lead to stuttering altough the framerate is high enough for fluent gaming with only one GPU). It is called AMD Dual Graphics or asymmetric CrossFire and uses AFR (Alternate Frame Rendering) to render different frames on the two graphic cores. The AMD Radeon HD 7640G + HD 7670M Dual Graphics is the combination of a integrated AMD Radeon HD 7640G APU processor graphics card and a dedicated entry level AMD Radeon HD 7670M graphics card in CrossFire combination. The power consumption of the chip should be similar to the Mobility Radeon HD 5650 and therefore suited for 15" laptops and up.ĪMD Radeon HD 7640G + HD 7670M Dual Graphics ► remove from comparison However, this only works if the laptop features enough DisplayPort outputs. Thanks to Eyefinity the graphics chip is able to theoretically drive up to 5 monitors simultaneously. However, the solution is not as mature as Nvidias 3D Vision. The AMD HD3D Technology offers support for Blu-Ray 3D and 3D displays (integrated and external).

The new UVD3 video decoder supports the decoding of 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 on the graphics card.įurthermore, the HD 6600M series integrates a HD audio controller to transmit HD audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g. Compared to the competitor, the 7670M positions itself in our tests slightly above the GeForce GT 630M on a level of the GeForce GT 550M. See at the end of this page for detailed gaming benchmarks. However, demanding games of 2011 like Battlefield 3 only run fluently in medium detail settings. 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.
