EPYC 7763 is a 64-bit 64-core x86 server microprocessor designed and introduced by AMD in March 2021. This multi-chip processor, which is based on the Zen 3 microarchitecture, incorporates eight Core Complex Dies fabricated on a TSMC advanced 7 nm process and a large I/O die manufactured by GlobalFoundries. The 7763 has a TDP of 280 W with a base frequency of 2.45 GHz and a boost frequency of up to 3.5 GHz. This processor supports up to two-way SMP and up to 4 TiB of eight channel DDR4-3200 memory per socket.

Cache[edit]

[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.
