Intel Xeon 6766e Processor
Intel Xeon 6766e Processor
The Intel Xeon 6766E is a server/workstation processor with 144 cores, launched in June 2024, at an MSRP of $10257. It is part of the Xeon 6 lineup, using the Sierra Forest-SP architecture with Socket 4710. To further increase overall system performance, up to two Xeon 6766E CPUs can link up in a multi-processor (SMP) configuration. Xeon 6766E has 108 MB of L3 cache and operates at 1900 MHz by default, but can boost up to 2.7 GHz, depending on the workload. Intel is building the Xeon 6766E on a 5 nm production process, the transistor count is unknown. The multiplier is locked on Xeon 6766E, which limits its overclocking capabilities.
With a TDP of 250 W, the Xeon 6766E is extremely power hungry, which means you need top-notch cooling. Intel’s processor supports DDR5 memory with an eight-channel interface. The highest officially supported memory speed is 6400 MT/s. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the computer, Xeon 6766E uses a PCI-Express Gen 5 connection. This processor lacks integrated graphics, you might need a graphics card.
