PNY Technologies, Inc. VCNRTXA400ATX-PB 4GB GDDR6 workstation graphics card

Entry-Level Workstation GPU

The PNY VCNRTXA400ATX-PB is a single-slot workstation graphics card built around the NVIDIA A400 GPU with 768 CUDA cores and 4GB of GDDR6 memory on a 64-bit interface. It connects through a PCIe 4.0 x8 slot and drives up to four displays via mini DisplayPort outputs at a maximum digital resolution of 5120 x 2880 at 60 Hz. The active fansink cooler fits within a 163 mm length, making it suitable for compact professional chassis.

Upgrade From Integrated Graphics

This card replaces a system's integrated graphics when professional applications require dedicated video memory and certified driver support across Windows 10, Red Hat Enterprise Linux 7.x, SUSE Linux Enterprise Desktop 15.x, OpenSuse 15, Fedora 31, Ubuntu 18.04, FreeBSD 11.x and Solaris 11. The jump is worth it for multi-monitor workflows, hardware-accelerated viewports or workloads that exceed shared system memory capacity. It is not for buyers who need more than 4GB of frame buffer or compute throughput beyond 768 CUDA cores.

PCIe 4.0 x8 Interface Limits

The PCIe 4.0 x8 connection provides half the lane count of a full x16 slot, which can constrain data transfer rates in bandwidth-heavy compute tasks or when moving large textures between system and video memory. The 64-bit memory bus also limits peak memory bandwidth relative to wider workstation cards. HDCP 2.2 support enables protected content playback on supported displays. Builders needing higher memory bandwidth or more than four display outputs should consider other options.
