NVIDIA went beyond just another GPU and it is rational to think that the GPU of today features millions if not a billion or more transistors. In the case of the 9300/9400 mGPU it features 16 core processors that could rival that of Intel or AMDs multi-core processors.
Fancy the idea of getting SLI from the mGPU with a dGPU (Discrete GPU)? Well look no further because the GeForce Series 9 mGPU Motherboard supports with a number of specified cards. You can expect to see major performance boosting, speaking of which, NVIDIA refers to this feature as GeForce Boost.
Hybrid SLI currently only supports the GeForce 8500GT and 8400GS cards. Another feature of the Hybrid SLI function is the Hybrid Power. This is really cool, literally, because it will turn off the dGPU when it isn’t required thereby reducing the amount of power consumed and heat generated. You will need to ensure you have a certified Hybrid PSU. You can find a lot more details of the supported dGPU and PSUs here.
If you’ve a mid-ranged dGPU like a 9500 or 9600 installed and wish to make use of additional processing with a PhysX enhanced game you can allow the mGPU to function as a dedicated PhysX processor. This relieves computational tasks by the main GPU to be offloaded to the PhysX. The enhancement simply translates to additional FPS and for the end user, hopefully a lot more frags.
CUDA – Compute Unified Device Architecture, they couldn’t come up with a more complex acronym to simply describe what is similar to the PhysX processor for commercial software developers. In a nutshell, you take the huge parallel processing power of the NVIDIA 16 core GPU and make it process threads in parallel. Tasks that benefit from this feature include: video transcoding, complex problem solving – ‘[email protected]’
Nothing can be more frustrating than watching a BluRay or even a DVD movie and having it jerk and stutter on your big High-Definition LCD or Plasma panel. You then blame your low-end HTPC processor. Well no more finger pointing or having to upgrade your processor to a more power hungry heat generating chunk of silicon. Offload the processing of H.264, VC1, and MPEG2 HD streams to the mGPU of the GeForce Series 9 Motherboards. At the same time you get to enjoy the richness of 7.1 LPCM (Linear Pulse Code Modulation) Audio.
