NVIDIA Tesla K20 GPU Computing Accelerators - Active

Mfg. Part Number:

Features & Benefits:

The NVIDIA® Tesla® K20 graphics processing unit (GPU) active accelerator board is a PCI Express, dual-slot full height (4.376 inches by 10.5 inches) form factor computing module comprising of a single GK110 GPU. The Tesla K20 active accelerator is designed for workstations and offers a total of 5 GB of GDDR5 on-board memory and supports PCI Express Gen2.

The Tesla K20 can be configured by the OEM or by the end user to enable or disable ECC that can fix single-bit errors and detect double-bit errors. Enabling ECC will cause some of the memory to be used for the ECC bits, so the user available memory will decrease by 10%. On the Tesla K20, the register files, cache, and DRAM are ECC protected.

Accelerate your scientific and technical computing with NVIDIA® Tesla® K20 GPU Accelerators. Now developers and researchers can enjoy faster performance and more accessibility with the latest generation of Tesla K20 GPUs based on NVIDIA Kepler™, the world's fastest and most efficient high performance computing architecture. Try the NVIDIA® Tesla K20 GPU accelerators and speed up your application by up to 10X.
