The preliminary specifications of NVIDIA's Tesla K40 GPGPU have been leaked. Codenamed Atlas, this chip is reportedly based on the new GK180 GPU. We have no idea what the GK180 is but the specifications look like a revision of the GK110. The new chip has 2880 CUDA cores and promises over 4 teraflops of single-precision and 1.4 teraflops of double-precision computing power. The memory has been doubled to 12GB GDDR5 and the memory bandwidth is 288GB/s.
The card appears to feature a dynamic overclocking feature, which works on ANSYS and AMBER workloads. The chip is configured to take advantage of PCI-Express gen 3.0 system bus. The card will be available in two form-factors, add-on card, and SXM, depending on which the maximum power draw is rated at 235W or 245W, respectively.
