NVIDIA is readying its next big single-GPU compute accelerator, the Tesla K40, codenamed "Atlas." A company slide that's leaked to the web by Chinese publication ByCare reveals its specifications. The card is based on the new GK180 silicon. We've never heard of this one before, but looking at whatever limited specifications that are at hand, it doesn't look too different on paper from the GK110. It features 2,880 CUDA cores.

The card itself offers over 4 TFLOP/s of maximum single-precision floating point performance, with over 1.4 TFLOP/s double-precision. It ships with 12 GB of GDDR5 memory, double that of the Tesla K20X, with a memory bandwidth of 288 GB/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.
