About this product
The NVIDIA RTX A4000 is a professional workstation graphics card based on the Ampere architecture, offering 6,144 CUDA cores, 192 third‑generation Tensor cores, and 48 second‑generation RT cores for demanding compute‑intensive and rendering workflows. It’s designed to deliver real‑time ray tracing and AI‑accelerated compute in a compact single‑slot form, fitting into a wide range of workstation chassis ([nvidia.com](https://www.nvidia.com/content/dam/en-zz/Solutions/products/workstations/nvidia-rtx-a4000-datasheet.pdf?)).
It features 16 GB of GDDR6 memory with error‑correction code (ECC) on a 256‑bit interface, providing 448 GB/s bandwidth, which supports high‑precision workloads and large datasets ([nvidia.com](https://www.nvidia.com/content/dam/en-zz/Solutions/products/workstations/nvidia-rtx-a4000-datasheet.pdf?)).
The card supports up to four simultaneous displays via DisplayPort 1.4a, with maximum resolutions up to 7680 × 4320 at 60 Hz, and supports AV1 decode and HDCP 2.2 for modern media workflows ([nvidia.com](https://www.nvidia.com/content/dam/en-zz/Solutions/products/workstations/nvidia-rtx-a4000-datasheet.pdf?)).
With a total board power of around 140 W and a single 6‑pin PCIe power connector, this single‑slot card balances performance and power efficiency, making it suitable for compact workstations and energy‑conscious setups ([pny.com](https://www.pny.com/File%20Library/Company/Support/Product%20Brochures/NVIDIA%20Quadro/English/nvidia-rtx-a4000-datasheet.pdf?)).
