Intel BGA 2579
The Intel Xeon D-2798NT is a server/workstation processor with 20 cores, launched in February 2022, at an MSRP of $2159. It is part of the Xeon D lineup, using the Ice Lake-D architecture with BGA 2579. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 40 threads. Xeon D-2798NT has 30 MB of L3 cache and operates at 2.1 GHz by default, but can boost up to 3.1 GHz, depending on the workload. Intel is making the Xeon D-2798NT on a 10 nm production node, the transistor count is unknown. The multiplier is locked on Xeon D-2798NT, which limits its overclocking potential.
With a TDP of 125 W, the Xeon D-2798NT consumes a lot of power, so good cooling is definitely needed. Intel's processor supports DDR4 memory with a quad-channel interface. The highest officially supported memory speed is 3200 MT/s, but with overclocking (and the right memory modules) you can go even higher. 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 D-2798NT uses a PCI-Express Gen 4 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon D-2798NT, 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 has added support for the newer AVX2 and AVX-512 instructions, too.
