Intel Xeon 6740e Processor
Intel Xeon 6740e Processor
The Intel Xeon 6740E is a server/workstation processor with 96 cores, launched in June 2024, at an MSRP of $5265. 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 6740E CPUs can work together in a multi-processor (SMP) configuration. Xeon 6740E has 96 MB of L3 cache and operates at 2.4 GHz by default, but can boost up to 3.2 GHz, depending on the workload. Intel is making the Xeon 6740E on a 5 nm production node, the transistor count is unknown. The multiplier is locked on Xeon 6740E, which limits its overclocking potential.
With a TDP of 250 W, the Xeon 6740E 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 6740E uses a PCI-Express Gen 5 connection. This processor lacks integrated graphics, you might need a graphics card.
