NVIDIA is moving around engineering samples of what it describes as "GM200 A1 graphics processor," in its shipping manifest. The sample was making its way from Taiwan, to Bangalore, India, from where it's likely pushed to the company's facilities in Bangalore and Hyderabad. A1 steppings of NVIDIA chips are usually pre-production, and bound for just a few more rounds of testing, before being upgraded to "A2" and mass-produced. German tech site 3DCenter.org also pulled out some likely specifications from its sources.
To begin with, the GM200, like the GM204, will be built on existing 28 nm silicon fabrication process, as both NVIDIA and AMD appear to have suffered design setbacks due to their common foundry partner, TSMC, not being able to set its next-gen 20 nm node up to speed in time. The GM200 is expected to feature over 4,000 CUDA cores, although the exact number is unknown. It is expected to widen the memory bus to 512-bit. Given the existing process, the GPU will be huge. Over 600 mm² huge. NVIDIA will probably bank on the energy efficiency of its "Maxwell" architecture to cope with thermal loads put out by a chip that big. The GM200-based "GeForce GTX TITAN II" could launch in the first half of 2015.
