Fresh from Nvidia’s premiere of a GF100 working prototype, the dual-GPU variant of GF100 is now rumoured to be released some time in May 2010, at earliest. Not surprisingly, the dual-GPU, if it releases, will be a good one or two months after the single-GPU GF100 variants.

However, the feasibility of such a product is very much debatable. While originally the GF100 was expected to have a TDP of ~200W and a 6+6 pin power configuration; the prototype demonstrated features 8+6 pin - the maximum official PCI configuration. It is likely that the final stepping will be significantly more energy efficient, however.

Fresh from Nvidia’s premiere of a GF100 working prototype, the dual-GPU
variant of GF100 is now rumoured to be released some time in May 2010,
at earliest. Not surprisingly, the dual-GPU, if it releases, will be a
good one or two months after the single-GPU GF100 variants.

However, the feasibility of such a product is very much debatable.
While originally the GF100 was expected to have a TDP of ~200W and a
6+6 pin power configuration; the prototype demonstrated features 8+6 pin -
the maximum official PCI configuration. It is likely that the final
stepping will be significantly more energy efficient, however.

Even if the final stepping consumers far less power, there is no doubt Nvidia have to make clock adjustments to keep the TDP under 300W, the maximum official load for the 8+6 pin configuration. Let us hope Nvidia are preparing accordingly, and this is not a repeat of the original GT200, to which a dual-GPU was simply not feasible.

Interestingly, a May/June release is nearly a half a year behind ATI’s HD 5900 series, which was itself delayed. It is likely that ATI will have a refresh of the HD 5000 series by the time Nvidia’s GF100 cards finally hit retail.

Apart from the single and dual-GPU GF100s, very little is known about the lower and mid end of the generation.
