Nvidia recently announced the new GeForce GTX 465 graphics card and that wasn't end of the Fermi cards. At the on-going Computex 2010, Nvidia displayed new Fermi architecture based GeForce GTX 470 graphics card with dual GPU on the same printed circuit board. That means a dual-GPU based Fermi graphics card is in the anvil. Nvidia made no comment on the availability and pricing of this dual-GPU Fermi graphics card.Nvidia already offers GeForce GTX 470 graphics card with 40nm fabrication process made GF100 GPU chip. However, this new reference card from add-in card maker Galaxy had two GF100 chip on the same PCB. This means there would be 8 (4 for each GPU) graphics processing clusters and total 896 CUDA cores or the stream processors.
We don't know about the memory part yet but this prototype graphics card would consume 430W which is twice the power that the single GPU bearing GTX 470. Also, the PCB measured full 12-inches long. Honestly, even this dual-GPU version needs quite a lot of tweaking to bring down the power consumption.
At the Computex, Galaxy showed only a prototype that may or may not go into production. Considering the power consumed by single GF100 GPU card, any dual-GPU card would be a power hog.
