Tesla K40 GPU Accelerator BD-06902-001_v05 | 1
OVERVIEW
The NVIDIA
®
Tesla
®
K40 graphics processing unit (GPU) is a PCI Express, dual-slot
computing module in the Tesla (267 mm length) form factor comprised of a single
GK110B GPU. The Tesla K40 is designed for servers and offers a total of 12 GB of
GDDR5 on-board memory and supports PCI Express Gen3. The Tesla K40 uses a passive
heat sink for cooling.
Tesla K40 boards ship with ECC enabled by default protecting the register files, cache
and DRAM. With ECC enabled, some of the memory is used for the ECC bits, so the
user available memory is reduced by ~6.25%. On the Tesla K40 the total available
memory with ECC turned on will be ~11.25 GB.
