The AMD EPYC 9755 is a server processor from the AMD EPYC 9005 series designed for very high compute density in data centers, virtualization environments, cloud infrastructure, container platforms, data analytics, and enterprise workloads. It features 128 Zen 5 cores and can process up to 256 threads simultaneously using Simultaneous Multithreading (SMT). The base clock speed is 2.70 GHz, with a maximum boost clock speed of up to 4.10 GHz.

The processor uses the SP5 socket and can be used in server platforms with up to two processors. It offers twelve DDR5 memory channels with ECC support and supports memory speeds up to DDR5-6000. This makes it suitable for systems with a high core count, high memory bandwidth, and extensive I/O connectivity.

Up to 128 PCIe 5.0 lanes are available for expansion cards, NVMe storage, network adapters, and accelerators. The AMD EPYC 9755 features 512 MB of L3 cache and a TDP of 500 W. Operation requires a compatible SP5 server platform, as well as cooling and power supplies designed for high power consumption.
