NVIDIA plans to introduce its Synergy (desktop edition of Optimus) technology at Computex. NVIDIA plans to launch their Desktop Optimus a.k.a Synergy at COMPUTEX Taipei this coming June and the best thing is that it is available freely and no license agreement is needed.
IDIA's new technology is designed specifically for Intel's Sandy Bridge desktop platform, particularly motherboards with Intel H61, H67, and Z68 chipsets (you can't access IGP with P6x). Unlike SLI, motherboard vendors needn't shell out a license fee or sign an agreement to implement the technology. A supportive motherboard will have authorization code implanted into SBIOS, much like SLI.
This technology works pretty much similar to LucidLogix's Virtu where it allows dynamic swapping between iGPU and dGPU based on the application's nature and also uses Intel Sandy Bridge Quick Sync technology while doing video transcoding jobs.
