Overview

Tesla K20s is an NVIDIA GPU entry in the Tesla K Series family. It is listed with Kepler architecture and GK110 silicon.

Key reference data: 2,496 CUDA cores/shaders, 5 GB GDDR5 memory, 320-bit memory bus, 225 W board power class.

Server accelerators should be checked against platform compatibility, cooling, power delivery, firmware, and driver or CUDA support.

Why It Mattered

Tesla K20s is a Tesla K Series accelerator from the Kepler generation. Its historical context is data-center deployment rather than gaming, so form factor, memory capacity, interconnect, virtualization features, and server compatibility are the details that make this entry useful.

Collector Relevance

For archival use, record the accelerator form factor, memory capacity, board part number, firmware or VBIOS, cooling type, bracket, interconnect support, power connectors, and the server or workstation it came from.

Used-Market Caution

Before buying used, confirm PCIe versus SXM or OAM form factor, passive airflow needs, auxiliary power, HBM size, firmware locks, ECC or retired-page errors, seller proof from nvidia-smi under load, and whether any vGPU or enterprise licensing is required.

Driver and Platform Notes

Driver support depends on architecture, operating system, and current NVIDIA driver branch.

Check the current NVIDIA Linux driver branch, distribution packages, and kernel compatibility for this exact GPU.

Check the current NVIDIA driver branch and OEM support policy for this exact GPU.
