The F1R08A HP NVIDIA Tesla K40 graphics card delivers up to 10x application performance when compared to CPUs, and up to 2.8x speed compared to the Tesla M2090. It features a 745MHz core that can be boosted (overclocked) by the end user up to 875MHz, and it has 2,880 CUDA generation cores (streaming processors) that allow it to perform hundreds of calculations simultaneously.
The Tesla K40 enables seamless integration of GPU computing with HPE servers for high-performance computing, large data center graphics, and virtual desktop deployments. To ensure that data is transferred to and from the processors as efficiently as possible, the card contains 12GB of GDDR5 RAM via a 384-bit memory interface. The original 750MHz memory clock speed is effectively boosted to 3GHz thanks to the fact that GDDR5 memory transmits data at four words per cycle. This results in a memory bandwidth of 288 GB/s.
