Advantech SKY-TESL-4500BS-32 NVIDIA RTX PRO 4500 Blackwell Server Edition 32GB Single-Slot Passive Server GPU with Multi-Instance GPU

Not every server has the slots or power for a 600 W dual-slot card, and many AI video and data processing jobs do not need one. The SKY-TESL-4500BS-32 is the NVIDIA RTX PRO 4500 Blackwell Server Edition from Advantech, an energy-efficient accelerator in a single-slot, full-height card. Advantech positions it for agile data processing, AI video and streaming in data centre, edge and cloud servers.

It carries 10,496 CUDA cores, 328 fifth-generation Tensor Cores with FP4 precision and 82 fourth-generation RT Cores, rated at 51 TFLOPS of FP32 performance. Memory is 32 GB of GDDR7 with ECC on a 256-bit interface, giving 800 GB/s of bandwidth. Multi-Instance GPU can divide the SKY-TESL-4500BS-32 into up to two instances of 16 GB each, which suits running two isolated services on one card. Fourth-generation RT Cores also give it ray-traced rendering where a server handles graphics work as well as AI.

The card connects over PCIe 5.0 x16 and draws up to 165 W through one PCIe CEM5 16-pin connector. It is headless, with no display outputs, and carries three ninth-generation NVENC and three sixth-generation NVDEC engines for encoding and decoding video streams. It relies on the server’s airflow for cooling, and the operating range is 10 °C to 45 °C.

We supply the SKY-TESL-4500BS-32 tested, and fit, configure and burn-in test it in the GPU servers we build, checking airflow and power across every card in the chassis. Where a build needs more memory and compute per card, the SKY-TESL-6000BS-96 is the 96 GB, 600 W Server Edition, and the SKY-QUAD-4500B-32 is the dual-slot workstation version of the RTX PRO 4500 Blackwell with 4x DisplayPort 2.1.
