NVIDIA has announced a new version of their popular Tesla M40 GPU – one with 24GB of high-speed GDDR5 memory. The name hasn’t really changed – the new GPU is named NVIDIA Tesla M40 24GB. If you are curious about the original version with less memory, we have a detailed examination of the original M40 GPU.
As support for GPUs grows – particularly in the exploding fields of Machine Learning and Deep Learning – there has been increasing need for large quantities of GPU memory. The Tesla M40 24GB provides the most memory available to date in a single-GPU Tesla card. The remaining specifications of the new M40 match that of the original: 7 TFLOPS of single-precision floating point performance.
The Tesla M40 continues to be the only high-performance Tesla compute GPU based upon the “Maxwell” architecture. “Maxwell” provides excellent performance per watt, as evidenced by the fact that this GPU provides 7 TFLOPS within a 250W power envelope.
Maximum single-GPU memory and performance: Tesla M40 24GB GPU

- In-Depth Comparison of NVIDIA Tesla “Maxwell” GPU Accelerators
To learn more about GPU-accelerated servers and clusters which provide the Tesla M40 24GB, please see our NVIDIA GPU technology page. Although we are able to provide the M40 in tower workstation systems, the design of the heatsink does not allow for quiet workstations.
