HPE Q0E21A NVIDIA Tesla P100 16 GB HBM2 workstation graphics card

HPE Q0E21A Tesla P100 16 GB HBM2 accelerator

The HPE Q0E21A houses an NVIDIA Tesla P100 GPU built on Pascal architecture with 3584 CUDA cores and 16 GB of HBM2 memory across a 4096-bit interface. It targets high-performance computing and deep-learning workloads that demand high double-precision throughput and memory bandwidth of 732 GB/s. The card draws up to 250 W and occupies a dual-slot footprint measuring 267 mm long. It is an OEM version supplied without retail packaging.

PCI Express 3.0 x16 dual-slot installation

The board installs in a PCI Express 3.0 x16 slot and requires a chassis that can accommodate a 267 mm dual-slot card and deliver 250 W through the appropriate power connectors. Its HBM2 memory is stacked on the GPU package using CoWoS technology, eliminating separate VRAM chips and freeing PCB space for dense server layouts. Builders must verify that their system provides sufficient airflow and power headroom for sustained computational tasks.

Sustained double-precision output of 4.7 teraFLOPS

Under continuous load the Tesla P100 maintains a core clock of 1190 MHz with memory at 715 MHz, delivering 4.7 teraFLOPS double-precision and 9.3 teraFLOPS single-precision performance. The 4096-bit HBM2 interface sustains 732 GB/s bandwidth, reducing bottlenecks in memory-bound HPC kernels. Thermal design assumes adequate case ventilation to keep the 250 W TDP stable during extended runs. Buyers needing higher memory capacity or newer architecture features should evaluate alternative accelerators.
