Advantech SKY-QUAD-A4000H16B NVIDIA RTX A4000H 16GB Single-Slot Workstation Graphics Card with 140W Active Cooling

Some GPU workloads are pure compute: inference on stored data, simulation or numerical work where the card never handles a video stream. The SKY-QUAD-A4000H16B is the NVIDIA RTX A4000H, a single-slot workstation graphics card supplied by Advantech, and its datasheet lists media acceleration and VR as not supported. That makes it a compute-focused build without NVENC or NVDEC, listed as an NVIDIA long-life SKU with product life extended until 2029.

The NVIDIA Ampere GPU carries 6,144 CUDA cores, 192 third-generation Tensor Cores and 48 second-generation RT Cores, for 19.2 TFLOPS of single-precision performance. Memory is 16 GB of GDDR6 with ECC on a 256-bit interface at 448 GB/s, which helps keep models and datasets resident on the card. CUDA, DirectCompute and OpenCL are supported for compute, with DirectX 12.07, Shader Model 5.17, OpenGL 4.68 and Vulkan 1.2 for graphics.

The SKY-QUAD-A4000H16B connects over PCI Express 4.0 x16 and draws up to 140 W, with active cooling in a single-slot design. Even without media engines, the card still carries four DisplayPort 1.4a outputs, driving four 4096 x 2160 displays at 120 Hz, four at 5120 x 2880 at 60 Hz or two at 7680 x 4320 at 60 Hz, so local displays remain available.

We supply the SKY-QUAD-A4000H16B tested, and we fit, configure and burn-in test it in the GPU computers and servers we build, with power, cooling and drivers checked as part of each build. Where video encode or decode is needed, the SKY-QUAD-A4000E16B is the same GPU with one NVENC and two NVDEC engines, and the SKY-QUAD-A5000E24B steps up to 24 GB in a dual-slot card.
