Advantech SKY-QUAD-A4000E16B NVIDIA RTX A4000 16GB Single-Slot Workstation GPU with 4x DisplayPort 1.4a

Video analytics, inspection and visualisation systems often need a capable GPU in one slot, with media engines for the camera streams and a supply life that matches the equipment. The SKY-QUAD-A4000E16B is the NVIDIA RTX A4000E, a single-slot workstation GPU supplied by Advantech and listed as an NVIDIA long-life SKU with product life extended until 2029. It suits industrial GPU computers that combine video, AI inference and display work.

The NVIDIA Ampere GPU has 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. One NVENC encoder and two NVDEC decoders, with AV1 decode, take video work off the CPU, and VR is supported. CUDA, DirectCompute and OpenCL cover compute, with DirectX 12.07, Shader Model 5.17, OpenGL 4.68 and Vulkan 1.2 for graphics.

The SKY-QUAD-A4000E16B connects over PCI Express 4.0 x16 and draws up to 140 W, with active cooling in a single-slot design. Four DisplayPort 1.4a outputs drive 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.

We supply the SKY-QUAD-A4000E16B 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. The SKY-QUAD-A4000H16B is the same GPU without media acceleration or VR, the SKY-QUAD-A5000E24B steps up to 24 GB in a dual-slot card, and the SKY-QUAD-4000EA-20 moves to Ada Lovelace with 20 GB in a single slot.
