Tesla K20c: specs and benchmarks

VS

Aggregate performance score

Tesla K20c provides poor gaming and benchmark performance at 7.79% of a leader's which is RTX PRO 5000 Blackwell.

Summary

NVIDIA started Tesla K20c sales 12 November 2012 at a recommended price of $3,199. This is a Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 5 GB of GDDR5 memory clocked at 1.3 GHz are supplied, and together with 320 Bit memory interface this creates a bandwidth of 208.0 GB/s.

Compatibility-wise, this is a dual-slot graphics 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.

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.
