Xeon E-2278G is a 64-bit octa-core high-end performance x86 workstation microprocessor introduced by Intel in early 2019. This processor, which is based on the Coffee Lake microarchitecture, is manufactured on Intel's 3rd generation enhanced 14nm++ process. The E-2278G operates at 3.4 GHz with a TDP of 80 W and a turbo boost of up to 5 GHz. This chip integrates Intel's UHD Graphics P630 GPU operating at 350 MHz with a burst frequency of up to 1.2 GHz and supports up to 128 GiB of dual-channel DDR4-2666 memory.

Cache

Main article: Coffee Lake § Cache

[Edit/Modify Cache Info]

Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes.
