Deskside AI supercomputer

The Supermicro Super AI Station ARS-511GD-NB-LCC-01-G2 is a tower workstation built around the NVIDIA GB300 Grace Blackwell Ultra Superchip. It integrates a 72-core Grace CPU with a Blackwell Ultra GPU that provides 252GB of HBM3e video memory. The system delivers up to 20 PFLOPS of AI performance in a liquid-cooled chassis designed for quiet office use.

Coherent memory and local NVMe limits

The platform unifies 496GB of LPDDR5X system memory with GPU memory for up to 748GB of coherent capacity. Local storage consists of two 1.92TB and two 960GB M.2 NVMe PCIe 4.0 drives. This fixed configuration suits large-model workloads but cannot be expanded with additional drive bays or memory modules.

Replaces rack AI servers for desk development

Teams moving model training and agentic AI development out of the data centre gain a plug-and-play system that runs from a standard NEMA 5-20 outlet. The jump is worth it when data privacy, low latency iteration, and native NVIDIA software stack support outweigh the need for multi-node scaling or hot-swap redundancy.

Questions sur cet article

Which memory configuration should I select for the 496GB LPDDR5X system?

The workstation ships with four 128GB LPDDR5X SOCAMM modules totalling 496GB; this is the only memory configuration offered for the Grace CPU superchip.

What does the 20 PFLOPS AI performance figure mean when the system is running locally?

It represents up to 20 petaFLOPS of AI compute from the integrated GB300 Grace Blackwell Ultra superchip, enabling trillion-parameter model work on the desk.

What interface do the four M.2 drives use and what speed does it cap at?

Two 1.92TB and two 960GB M.2 drives run on PCIe 4.0 NVMe, limiting each drive to the 4.0 lane bandwidth.
