The Nvidia Tesla M40 is a dual-slot 10.5 inch Express Gen3 card with a single Nvidia Maxwell GM200 graphics processing unit (GPU). The Tesla M40 has 12 GB GDDR5 on-board memory and a 250 W maximum power limit. It uses a passive heat sink for cooling, which requires system air flow to properly operate the card within its thermal limits. The Tesla M40 is designed for scale-out learning training deployment. For performance optimization, Nvidia GPU Boost feature is supported. By adjusting the CPU clock dynamically, maximum performance is achieved within the power cap limit.
