NVIDIA started Tesla K20c sales 12 November 2012 at a recommended price of $3,199. This is Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 5 GB of GDDR5 memory clocked at 5.2 GHz are supplied, and together with 320 Bit memory interface this creates a bandwidth of 208.0 GB/s.

Compatibility-wise, this is dual-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 267 mm. One 6-pin and one 8-pin connectors are required, and power consumption is at 225 Watt.

We have no data on Tesla K20c benchmark results.

Benchmark performance

Non-gaming benchmark performance of Tesla K20c. Note that overall benchmark performance is measured in points in 0-100 range.

  • Octane Render OctaneBench

This is a special benchmark measuring graphics card performance in OctaneRender, which is a realistic GPU rendering engine by OTOY Inc., available either as a standalone program, or as a plugin for 3DS Max, Cinema 4D and many other apps. It renders four different static scenes, then compares render times with a reference GPU which is currently GeForce GTX 980. This benchmark has nothing to do with gaming and is aimed at professional 3D graphics artists.
