The nForce 780a SLI mostly shares the same capabilities of the nForce 780i SLI launched late last year, while the nForce 750a SLI is a performance oriented board minus the enthusiast touches. Both the nForce 780a and 750a platforms have integrated GPU solutions that incorporate the GPU prowess equivalent to that on the GeForce 8200 MCP - which has the graphics crunching power to tackle Full HD videos with its PureVideo HD engine (though NVIDIA declined to comment on which VP engine it is running at the moment). Take note however that the mainstream nForce 730a does not support HybridPower but will still feature GeForce Boost for the added performance.
The nForce 200 companion chip to the nForce 780a SLI and nForce 750a SLI handles the full bandwidth PCIe 2.0 busses on these motherboard platforms just as it has done so for the Intel equivalent platform. However, NVIDIA has recently been awarded patents to some of the technologies incorporated on the nForce 200 chip which were not shared previously disclosed and we'll cover them in brief:-
The GeForce 8200 MCP itself is targeted as the new low cost entry level DX10 capable GPU that has potential to set a new baseline for Vista Premium mGPU certified board. Other features of the GeForce 8200 MCP is its PureVideo HD engine that fully offloads processing of all CODECs used on Blu-ray and HD DVD discs (MPEG-2 , VC-1 and H.264) so that low cost CPUs can be used, Hybrid SLI, MediaShield with RAID 5 and Gigabit with FirstPacket technologies. The GeForce 8200 is mighty robust for a single-chip platform solution.
