Built on two Kepler GPUs, the NVIDIA Tesla K80 GPU Accelerator is intended for use in servers and supercomputers. The K80 is a dual GPU unit which utilizes two GK210B chipsets. As a unit this card offers a total of 4992 CUDA cores clocked at 560 MHz coupled to 24GB of GDDR5 vRAM with a 384-bit memory interface and a 480 GB/s bandwidth. This card features no outputs for displays, it is designed to serve as a hardware accelerator using the CUDA cores in the GPU. Its CUDA cores are arranged using NVIDIA’s Kepler architecture. Using compatible APIs, software can leverage the massively parallel processing abilities. Projects that can take advantage of the parallel processing include computational fluid dynamics and structural mechanics, numeral analytics, and molecular dynamics.
While the GPU by default runs at 560 MHz, it can be boosted up to 875 MHz to greatly increase processing power. This boost is initiated when the card is under load and there is enough temperature overhead to allow the card to use more power. Because this card is built to be used in servers, it features passive heatsink cooling which relies on the airflow and cooling present in a server structure. The passive heatsink is silent and increases reliability because it contains no moving parts.
