What is Xeon CPU?
The Xeon CPU is a line of high-performance processors from Intel Corporation, designed for server, data center, and enterprise computing applications. Xeon is a direct competitor to AMD’s EPYC series, and is widely used in high-end servers, data centers, and cloud computing environments.
Architecture and Design
Xeon CPUs are based on the 10th Gen Core architecture, which is a continuation of the earlier Ivy Bridge, Broadwell, and Skylake architectures. The Xeon CPU lineup includes a variety of processors, from low-end, entry-level models to high-end, top-of-the-line models. Each Xeon processor has a unique name, codename, and pin configuration.
| CPU Name | Codename | Pin Configuration |
|---|---|---|
| 3rd Gen Core | Nehalem | 25 pins |
| 4th Gen Core | Sandy Bridge | 28 pins |
| 5th Gen Core | Ivy Bridge | 25 pins |
| 6th Gen Core | Broadwell | 35 pins |
| 7th Gen Core | Skylake | 32 pins |
| 8th Gen Core | Rocket Lake | 30 pins |
| 9th Gen Core | Lakefield | 28 pins |
| 10th Gen Core | Emerald Lake | 32 pins |
