Advantech SKY-TESL-L40-48P NVIDIA L40 48GB GDDR6 Data Centre Graphics Card with ECC Memory and 4x DisplayPort

Virtual workstations and server-side rendering need real graphics hardware with enough memory for professional scenes. The SKY-TESL-L40-48P is the NVIDIA L40 from Advantech, a universal compute and graphics data centre GPU on the Ada Lovelace architecture with 48 GB of GDDR6. It is a passive, dual-slot PCIe card that suits video, AI, virtualised desktop and graphics applications in the enterprise, in the cloud and at the edge.

The GPU carries 18,176 CUDA cores, 568 fourth-generation Tensor Cores and 142 third-generation RT Cores, rated at 88 TFLOPS FP32, with DLSS 3 support. Memory is 48 GB of GDDR6 with ECC at 864 GB/s. NVIDIA vGPU support lets the SKY-TESL-L40-48P run mid-to-high-end design workflows on NVIDIA RTX Virtual Workstation and productivity applications on NVIDIA Virtual PC, so one card can serve several remote users. Fourth-generation Tensor Cores handle AI inference alongside the graphics work on the same card. Multi-Instance GPU and NVLink are not supported.

The card connects over PCI Express 4.0 x16 and draws up to 300 W through a 16-pin PCIe connector. It has four DisplayPort 1.4 outputs, plus three NVENC and three NVDEC engines with AV1 encode and decode for streaming and video analytics. The card is dual slot and full height, with a passive heatsink that relies on the server’s airflow.

We supply the SKY-TESL-L40-48P tested, and fit, configure and burn-in test it in the GPU servers we build, checking airflow and power across the chassis. The SKY-TESL-L40S-48P uses the same 48 GB of memory at 350 W with higher FP32 throughput, and the SKY-TESL-L4-24P is the low-profile 72 W card for inference at the edge.
