Frequently Asked Questions

What is the difference between P47877-001, R8T26C, and P48409-001?

All three are HPE variants of the NVIDIA A16 64GB GDDR6 PCIe 4.0 x8 GPU — P47877-001 and P48409-001 use the -001 and standard part number suffixes respectively, while R8T26C uses the HPE Smart Buy/OEM alphanumeric format. All are functionally identical and interchangeable in supported HPE ProLiant servers.

How many virtual desktop users can an NVIDIA A16 support?

With NVIDIA vGPU software and 4GB vGPU profiles, a single A16 card supports up to 16 simultaneous virtual desktop users. With 8GB profiles, it supports 8 users, and with 16GB profiles, 4 users. The optimal profile size depends on your workload — knowledge workers typically use 4GB profiles, while CAD/creative users may require 8GB or 16GB.

Does the NVIDIA A16 support CUDA compute workloads directly?

Yes — NVIDIA A16 supports CUDA compute workloads, but it is primarily optimized for vGPU virtualization density rather than raw compute. For dedicated AI training or HPC compute, NVIDIA A30, A100, or H100 GPUs provide significantly higher compute performance. The A16 excels at GPU virtualization density for VDI and cloud workstation deployments.

The HPE P47877-001 NVIDIA A16 delivers 64GB of GDDR6 GPU memory across four Ampere dies with PCIe 4.0 x8 connectivity — providing the highest-density NVIDIA vGPU capacity per slot for HPE ProLiant VDI, cloud workstation, and multi-user GPU virtualization deployments requiring up to 16 virtual GPU instances per card.
