Deploying a single-socket architecture has several key advantages over multi-processor systems, including, the absence of the CPU-CPU interconnect, which frees up more of the processor’s I/O capacity for PCIe expansion and avoids latency issues related to Non-Uniform Memory Access (NUMA).

The enhanced PCIe lane availability compared to previous generations means more and faster networking, storage, and acceleration devices can be added to each system, increasing overall system compute capacity and rack density

Customers can expect significant benefits when deploying single-processor servers to run their applications. For many cloud and storage-centric workloads, performance that previously required two CPUs per system can be achieved or even exceeded with a single processor. By deploying single-socket servers, customers can realize cost savings not only on the initial acquisition of the servers, but also due to reduced power consumption, and lower thermal load reducing cooling requirements.
