CPU Comparison
Intel Xeon 6521P vs Intel Xeon 6741P
A side-by-side comparison of specs, performance and value. The Intel Xeon 6521P is a 24-core server processor built on the Intel 3 process, featuring 144 MB of L3 cache, eight DDR5-6400 memory channels, 136 PCIe 5.0 lanes, and a 225 W TDP. Designed for single-socket deployments, it targets general-purpose data center workloads, databases, virtualization, and edge applications that demand high I/O and memory bandwidth. Launching in Q1 2025 as part of the Granite Rapids family, the 6521P lacks integrated graphics and ships in a large FCLGA4710 package tailored to enterprise platforms. It also includes modern data-center features such as Intel AMX, QuickAssist Technology, and comprehensive security and virtualization capabilities.
