1. The NVIDIA Tesla K20 graphics processing unit GPU accelerator is a PCI Express dual slot full height 4 376 inches by 10 5 inches by 1 52 inches form factor computing module comprising of a single GK110 GPU The Tesla K20 is designed for servers 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 or error correcting codes 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 1076 On the Tesla K20 the register files cache and DRAM are ECC protected KEY FEATURES GPU Number of processor cores 2496 Processor core clock 706 MHz gt Package size 45 mm x 45 mm 2397 pin ball grid array S FCBGA Board PCI Express Gen2 x16 system interface gt Physical dimensions 4 376 inches x 10 5 inches dual slot Display Connectors None Tesla K20 GPU Accelerator BD 06455 001 v05 1 Overview Power Connectors gt One 6 pin PCI Express power connector gt One 8 pin PCI Express power connector Memory Memory clock 2 6 GHz Memory bandwidth 208 GB sec gt Interface 320 bit Total board memory 5 GB 20 pieces of 64M x 16 GDDR5 SDRAM BIOS 2Mbit Serial ROM TESLA K20 BLOCK DIAGRAM Figure 1 is the block diagram for the Tesla K20 GPU dual slot computing pro2. 0 95 0 25 0 0374 0 010 1 70 0 25 TYP 10 067 0 0101 Figure 5 Tesla K20 GPU Accelerator POSITION 1 INDICATOR Mechanical Specifications 0 40 REF 0 20 REF DETAIL A ALIGNMENT RIB 3 17 0 15 0 125x 0 006 1 4 0 15 0 0551 0 006 11 4 0 25 0 449 0 0101 73 REF 0 287 42 TYP eil 0 165 18 110 25 0 7133 0 010 8 Pin PCI Express Power Connector BD 06455 001 v05 7 Table 2 6 Pin PCI Express Power Connector Pinout Mechanical Specifications Pin Number Description 12 V 12 V 12 V GND Sense oy e WwW N e GND Table 3 8 Pin PCI Express Power Connector Pinout Pin Number Description 12 V 12 V 12 V Sensel GND 0 GND F3 Tesla K20 GPU Accelerator GND BD 06455 001 v05 8 POWER SPECIFICATIONS The Tesla K20 GPU accelerator requires power from the PCI Express connector as well as one or two auxiliary power connectors Table 4 Auxiliary Power Connectors 8 Pin Header 6 Pin Header Support Notes Connect 8 pin cable Connect 6 pin cable Yes Connect 8 pin cable No cable installed Yes 8 pin cable must supply 150W Connect 6 pin cable Connect 6 pin cable No 8 pin connector should always be connected Note Detailed information about power draw by rail will be available to authorized system partners
