Intel · Xeon 6 · 2024 · LGA4710
The Intel Xeon 6756E is a server processor with 128 cores, released in 2024 at an MSRP of $6,300. It is part of the Xeon 6 lineup, using the Xeon 6 platform, and fits the LGA4710 socket. Internally, it is built on the "Crestmont" architecture. The Xeon 6756E has a base clock of 1.8 GHz and can boost up to 2.6 GHz depending on workload and thermal headroom. Intel manufactures the "Crestmont" silicon on a Intel 3 process node. This processor supports DDR5 memory across 8 channels, up to 1TB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 88 lanes of PCIe 5.0 available for storage, networking and accelerators. With a TDP of 225W, the Xeon 6756E runs hot and requires a capable cooling setup. The cache hierarchy consists of 96KB/core of L1, no dedicated of L2, and 128MB of L3 cache — a substantial cache pool well suited to memory-bound enterprise and virtualization workloads.
E-core 'Sierra Forest' SKU built entirely from efficiency cores for maximum thread density per socket and per watt. No hyperthreading — thread count equals core count. Targets cloud-native, hyperscale and microservices workloads over single-thread performance.
