TYAN B8033G70E4HR-CGN-1C-B-7C13 rack server, 64-core EPYC, 16 GB DDR4, 1 TB NVMe, 100 Gb NIC

1U rack server for compute density

The TYAN B8033G70E4HR-CGN-1C-B-7C13 is a 1U rack server built around a single 64-core AMD EPYC processor running at 2.4 GHz with 128 threads and 384 MB cache. It ships with 16 GB of DDR4-3200 memory installed across one of sixteen total DIMM slots and a 1 TB NVMe M.2 boot drive. Dual 800 W 80+ Platinum hot-swap power supplies provide redundancy in a chassis measuring 43 mm high, 440 mm wide and 697 mm deep.

Upgrade from smaller core counts

This system replaces platforms limited to lower thread counts or slower fabric links when workloads scale beyond 128 threads or demand 100 Gb networking throughput. The jump is worth it when memory capacity must grow beyond the single installed module using the fifteen vacant DDR4 slots, or when local NVMe storage must be added through the two empty U.2 hot-swap bays with tool-less trays. Buyers who need more than one CPU socket or integrated GPU acceleration cannot be served by this single-socket design.

Practical limits of OCP 3.0 and single-socket memory

Network throughput is bound to the single-port Broadcom BCM95750-N1100G OCP 3.0 card rated at 100 Gb, so aggregate bandwidth cannot exceed that link without additional adapters. Memory expansion stops at sixteen DDR4 slots with no support for newer memory types, capping total capacity and speed at the DDR4-3200 standard. The dedicated 1000Base-T IPMI port handles out-of-band management separately from the data plane.
