What do you do if you need GPU power for AI and other compute-intensive workloads, but lack the infrastructure for liquid cooling?

Supermicro has the answer. The company just introduced a 10U server powered by AMD Instinct MI355X GPUs that’s air-cooled.

The new server, showcased at the recent SC25 conference in St. Louis, is Supermicro model AS -A126GS-TNMR.

Each server is powered by the customer’s choice of dual AMD EPYC 9004 or 9005 Series CPUs with up to 384 cores and 768 threads. The system also features a total of eight AMD Instinct MI355X onboard OAM GPU accelerator modules, which are air-cooled. (OAM is short for OCP Accelerator Module, an industry-standard form factor for AI hardware.) In addition, these accelerated GPU servers offer up to 6TB of DDR5 system memory.

While the systems are air-cooled with up to 19 heavy-duty fans, there’s no penalty in terms of cooling capacity. In fact, AMD has boosted the GPU’s thermal design point (TDP)—the maximum amount of heat a server’s cooling system can handle—from 1000W to 1400W.

Also, compared with the company’s air-cooled 8U server based on AMD Instinct MI350X GPUs, the 10U server offers up to double-digit more performance, according to Supermicro . For end users, that means faster data processing.

More Per Rack

The bigger picture: Supermicro’s new 10U option lets customers unlock higher performance per rack. And with their choice of 10U air cooling or 4U liquid cooling, both powered by the latest AMD EPYC processors.

Supermicro’s GPU solutions are designed to offer maximum performance for AI and inference at scale. And they’re intended for use by both cloud service providers and enterprises.
