Supermicro AS-4125GS-TNRT — Full Technical Specifications

This Supermicro system is a dual-socket EPYC platform built around eight double-width accelerator positions — a GPU server in the plainest sense, where the chassis, power and airflow exist to serve the cards. It is bought for inference fleets, for visualisation and rendering, and for training work that fits inside one node. Supplied new and configured with us before build.

Full Specifications

Supermicro publishes its specifications at component level, which makes this the most literal table on the site and the most useful one for checking compatibility. Read the accelerator rows as a set: the supported list, the interconnect between processor and card, and the optional bridge between cards. That third row is the one people miss, and whether it is fitted changes what multi-card workloads can do. Note the processor footnote about board revision — a platform that supports a newer processor family only on a later board is a question to settle before ordering, not after. Memory is quoted at one and two modules per channel, and the difference in speed between them is real.
