NVIDIA started Tesla K20Xm sales 12 November 2012 at a recommended price of $7,699. This is a Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 6 GB of GDDR5 memory clocked at 5.2 GHz are supplied, and together with 384 Bit memory interface this creates a bandwidth of 249.6 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. No additional power connector is required, and power consumption is at 235 Watt.

It provides poor gaming and benchmark performance at


of a leader's which is NVIDIA GeForce RTX 4090.
