AMD EPYC 9355 Tray Processor - 100-000001148

AMD EPYC 9355 is a 5th generation server processor aimed at serious workloads – virtualization, databases, high-load services and heavy backend. It runs at a base frequency of 3.55 GHz with Turbo up to 4.4 GHz, which helps with better response during burst workloads. You get 32 physical cores and 64 threads, built on Zen 5 architecture and 4 nm technology. The processor comes in Tray variant without included cooler and without integrated graphics, so your configuration is maximally focused on CPU performance.

What you get is a serious balance between many cores and high frequencies, which is important for workloads that combine parallel tasks and single-thread sensitive applications. The huge 256 MB cache helps reduce access to RAM during complex requests and heavy transactions – especially for databases and in-memory applications. With a 12-channel DDR5 controller and support up to 6 TB RAM per socket, you can build machines with huge memory capacity for virtualization, analytics and large cache layers. TDP of 280 W requires serious cooling and well-planned airflow in the server chassis, but it gives you stable thermal headroom for long periods of full load. Socket SP5 ties you to the current AMD Epyc platform, oriented towards modern data center boards and infrastructure.

• The processor has 32 physical cores and 64 threads, which is excellent for virtualization, container environments and parallel services on a single socket.
• Base frequency 3.55 GHz and Turbo up to 4.4 GHz provide a good combination of throughput and fast response during short-term peaks in the workload.
• It uses Zen 5 architecture and 4 nm manufacturing process, aimed at better energy efficiency and higher per-core performance.
• The huge 256 MB cache reduces latency for frequently used data and is especially useful for databases and large in-memory applications.
• Support for DDR5, including DDR5-6400, with a 12-channel controller allows high memory bandwidth for RAM-intensive workloads.
• Ability for up to 6 TB RAM per socket gives freedom for massive virtualization hosts and analytical systems with huge working sets.
• TDP of 280 W means you must provide quality cooling and PSU, but you get stability during long-term 24/7 high load.

Who it is suitable for: if you build a server for virtualization, databases, heavy microservices or analytics, where the combination of many cores, huge cache and lots of RAM makes the difference, this AMD EPYC 9355 is a strong choice. It is not aimed at home or budget servers – here we talk about serious infrastructure that will work under constant load. It is also suitable if you want to consolidate many smaller machines into a smaller number of powerful servers.

The strongest in this model is the combination of 32/64 cores/threads, 256 MB cache and 12-channel DDR5 with up to 6 TB RAM per socket – a platform that gives you quite a bit of freedom to grow within a single server, instead of unnecessarily stretching the cluster.
