New GK104 SKU Details Surface
We know from a late-March article that NVIDIA is working on two new SKUs based on its GK104 silicon, for launch in May. With the Kepler architecture, particularly with the design of the new-generation Streaming Multiprocessors (SMX), NVIDIA substantially increased CUDA core density. Each SMX holds 192 CUDA cores, and as with the previous-generation Fermi architecture, the SMX count is the only thing NVIDIA can tinker with, to control CUDA core count in new GPUs. GeForce GTX 680's little brother, hence will have 7 out of 8 SMX units enabled, and end up with a CUDA core count of 1344. This leaves easier to configure parameters such as clock speeds, for NVIDIA to design the perfect SKU to capture a price-point. NVIDIA is targeting the sub-$399 market, while somehow maintaining competitiveness with Radeon HD 7950.
Specifications of the new SKU follow.

I really hope they dont cut down the vrms even further.
Might be the first time I might consider going back to the green side if the price/performance is right :)
While here's my question... why not sooner? Face it these are from production GK104 wafers, you mean Nividia doesn't have enough chips from those wafer to start production. I understand the GTX680 as it got changed midstream, but these products have been pretty well canned in terms of design and PCB while they've known what they need to beat 2-3 months back in terms of 7890/7950. So it would appear everything shoulds be ready but we wait again? By May they'll have lost any momentum gain by the GTX680 and without SKu's to buy that waning fast.
