RTX A4000

The RTX A4000 is a mainstream member of NVIDIA's Ampere-generation RTX A-series professional lineup, the workstation counterpart to the consumer GeForce RTX 30 series. Built on the Ampere architecture, it sits two generations before the current RTX PRO Blackwell professional cards and serves as an efficient single-slot option within this professional generation.

The card carries 16GB of GDDR6 memory with ECC support, paired with a 256-bit memory bus delivering 448 GB/s of bandwidth. It features 6144 CUDA cores for 19.2 TFLOPS of FP32 throughput, along with 2nd-generation RT cores and 3rd-generation Tensor cores. In a compact single-slot form factor on a PCIe 4.0 x16 interface and rated at just 140W, it runs NVIDIA's ISV-certified professional drivers.

The RTX A4000 is designed for professional visualization, CAD/CAE, 3D rendering, real-time ray tracing, simulation, AI/ML development and inference, data science, and video production. Its single-slot design and modest power draw make it well suited to compact or multi-GPU workstation builds where space and efficiency matter, while its 16GB framebuffer handles a broad range of professional projects.
