NVIDIA started Tesla M40 sales 10 November 2015. This is a Maxwell 2.0 architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 12 GB of GDDR5 memory clocked at 6 GB/s are supplied, and together with 384 Bit memory interface this creates a bandwidth of 288.4 GB/s.

Compatibility-wise, this is dual-slot card attached via PCIe 3.0 x16 interface. Its manufacturer default version has a length of 267 mm. 8-pin EPS power connector is required, and power consumption is at 250 Watt.
