OVERVIEW
The NVIDIA®Tesla™ C2050 / Tesla C2070 computing processor board is a PCI Express
2.0 full-height (4.376 inches by 9.75 inches) form factor computing add-in card based on
the NVIDIA Tesla T20 graphics processing unit (GPU). This board is targeted as high-
performance computing (HPC) solution for PCI Express systems.
The Tesla C2050 / Tesla C2070 is capable of running 515 GFLOPs/sec of double precision
processing performance. Tesla C2050 comes standard with 3 GB of GDDR5 memory at
144 GB/s bandwidth. Tesla C2070 comes standard with 6 GB of GDDR5 memory.
Both the Tesla C2050 and Tesla C2070 can be configured by the end user to enable or
disable ECC or error correcting codes that can fix single-bit errors and report 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 to 2.625 GB for Tesla C2050 and 5.25 GB for Tesla
C2070.
