Advantech SKY-QUAD-4000A-20 NVIDIA RTX 4000 Ada 20GB Single-Slot Workstation GPU with 130W Power Draw

In multi-card GPU computers, the width of each card often decides how much fits in the chassis. The SKY-QUAD-4000A-20 is the NVIDIA RTX 4000 Ada from Advantech, a single-slot, full-height workstation GPU with 20 GB of GDDR6 and ECC at a 130 W maximum. Advantech lists the RTX Ada family for rendering, AI, graphics and compute, with professional application certification from independent software vendors.

The Ada Lovelace GPU has 6,144 CUDA cores, 192 fourth-generation Tensor Cores and 48 third-generation RT Cores, with single-precision performance rated at 26.7 TFLOPS. Memory runs on a 160-bit interface at 280 GB/s. Family features include AV1 encode and decode for video pipelines, NVIDIA GPUDirect RDMA support for moving data directly between network adapters and the GPU, and NVIDIA Mosaic for spanning several displays as one desktop.

The SKY-QUAD-4000A-20 connects over PCI Express 4.0 x16 and has four DisplayPort 1.4a outputs, driving four 4096 x 2160 displays at 120 Hz, four at 5120 x 2880 at 60 Hz or two 7680 x 4320 displays at 60 Hz. It supports DirectX 12, Shader Model 6.6, OpenGL and Vulkan 1.3, with CUDA, DirectCompute and OpenCL. Power comes through one PCIe CEM5 16-pin connector, with a 1x PCIe 8-pin adapter cable included. Active cooling keeps the card to a single slot, which leaves room for capture, network or further GPU cards.

We supply each card tested, and we fit, configure and burn-in test the SKY-QUAD-4000A-20 in the GPU computers and servers we build. For low-profile chassis, the SKY-QUAD-4000SA-20 uses the same core count at 70 W. The SKY-QUAD-4500A-24 adds memory on a dual-slot card, and the SKY-QUAD-4000B-24 is the Blackwell generation single-slot card on PCIe 5.0.
