AMD EPYC 9634

The AMD EPYC 9634 is a high-core-count server processor based on the Zen 4 architecture, built on a 5nm process. With 84 cores and 168 threads, it delivers exceptional multi-threaded performance while maintaining a lower TDP (290W) compared to its higher-end siblings. It features a base clock of 2.25 GHz and a boost clock of up to 3.7 GHz, along with a massive 384MB of L3 cache.

• Memory & I/O: Supports 12-channel DDR5-4800 RAM and 128 PCIe 5.0 lanes, ensuring high bandwidth for storage and accelerators.
• Use Cases: Ideal for cloud computing, virtualization, and enterprise workloads where a balance between power efficiency and performance is critical.
• Socket: Uses the SP5 (LGA 6096) socket and is compatible with dual-socket (2P) configurations.

AMD EPYC 9654

The AMD EPYC 9654 is AMD’s flagship 96-core processor in the Genoa lineup, offering 192 threads with a 2.4 GHz base clock and up to 3.7 GHz boost. It has the same 384MB L3 cache but operates at a higher 360W TDP, making it a powerhouse for HPC, AI, and data center workloads.

• Memory & I/O: Like the 9634, it supports 12x DDR5-4800 and 128 PCIe 5.0 lanes, maximizing throughput for GPUs, NVMe storage, and high-speed networking.
• Use Cases: Optimized for dual-socket (2P) servers, it excels in scientific computing, database servers, and large-scale virtualization.
• Competitive Edge: Offers the highest core density in AMD’s lineup, competing directly with Intel’s Xeon Platinum CPUs.

AMD EPYC 9654P

The AMD EPYC 9654P is essentially the single-socket (1P) version of the EPYC 9654, featuring the same 96 cores, 192 threads, 2.4 GHz base clock, and 3.7 GHz boost. It also retains the 384MB L3 cache and 360W TDP.

• Key Difference: Unlike the 9654, it is restricted to single-socket systems, making it ideal for workstations, edge servers, and high-performance single-node deployments.
• Use Cases: Perfect for rendering farms, AI inference, and memory-intensive applications where dual-socket setups are unnecessary.
• Cost Efficiency: Eliminates the need for dual-socket motherboards, reducing overall system costs while maintaining extreme core counts.

Model	Cores/Threads	Base/Boost Clock	TDP	Cache	Socket Support	Best For
EPYC 9634	84C/168T	2.25 GHz / 3.7 GHz	290W	384MB L3	2P (Dual-Socket)	Cloud, Virtualization
EPYC 9654	96C/192T	2.4 GHz / 3.7 GHz	360W	384MB L3	2P (Dual-Socket)	HPC, Databases, AI
EPYC 9654P	96C/192T	2.4 GHz / 3.7 GHz	360W	384MB L3	1P (Single-Socket)	Workstations, Edge AI

Final Recommendation

• For maximum scalability (2P): EPYC 9654 (96 cores, dual-socket).
• For single-node performance: EPYC 9654P (same as 9654 but 1P-only).
• For power efficiency & high core count: EPYC 9634 (84 cores, lower TDP)
