The AMD EPYC 9755 is a high core count server processor for data centre operators and system builders working with demanding virtualisation, cloud, analytics or compute workloads. Its 128 cores and 256 threads suit servers that need to run many concurrent tasks, while its SP5 socket identifies the platform it is designed for.

With a 2.7 GHz base clock and boost speeds up to 4.1 GHz, the EPYC 9755 combines substantial parallel processing capacity with higher clock speeds for workloads that can benefit from them. It has 512 MB of L3 cache and supports 12 memory channels with DDR5 memory speeds up to 6400 MT/s. PCIe 5.0 provides 128 lanes for compatible expansion devices and high-speed storage. AMD Infinity Architecture and AMD Infinity Guard are among its supported technologies. The processor has a 500W default TDP, so the server platform and cooling solution need to be designed to handle its power and thermal requirements.

Key features

• 128 CPU cores and 256 threads for heavily parallel server workloads
• Up to 4.1 GHz boost clock alongside a 2.7 GHz base clock
• 512 MB L3 cache
• 12-channel DDR5 memory support up to 6400 MT/s
• 128 lanes of PCIe 5.0 connectivity

• SP5 platform for compatible server systems

Compatibility

This tray processor is for a compatible SP5 server motherboard and system. Confirm that the complete platform supports the EPYC 9755, its 500W TDP, the required memory configuration and adequate cooling before purchase. The package is listed as CPU only; a cooler is not included. Good to know: tray processors are intended for system integration, so check the server maker’s compatibility and thermal guidance rather than assuming an existing server can support this CPU.

Specifications

For server builds that need a large number of cores, broad memory bandwidth and PCIe 5.0 expansion, the EPYC 9755 brings these capabilities together in an SP5 processor built for demanding data centre workloads.
