Description
Intel SRMX7 Xeon E-2478 Octa-core (8 Core) 2.80GHz 16GT/s DMI 24MB L3 Cache Socket FCLGA1700 Processor
The Intel Xeon E-2478 is a server/workstation processor with 8 cores, launched in December 2023, at an MSRP of $568. It is part of the Xeon E lineup, using the Raptor Lake architecture with Socket 1700. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 16 threads. Xeon E-2478 has 24 MB of L3 cache and operates at 2.8 GHz by default, but can boost up to 5.2 GHz, depending on the workload. Intel is making the Xeon E-2478 on a 10 nm production node, the transistor count is unknown. The multiplier is locked on Xeon E-2478, which limits its overclocking potential.
With a TDP of 80 W, the Xeon E-2478 consumes a good deal of power, so decent cooling is needed. Intel’s processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 4800 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 machine, Xeon E-2478 uses a PCI-Express Gen 5 connection. This processor lacks integrated graphics, you might need a graphics card. Inside the box you will not only find the processor, but also a Intel DVA-B cooler.
Hardware virtualization is available on the Xeon E-2478, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512
