Ryzen Threadripper 3990X is a 64-bit 64-core high-performance x86 desktop microprocessor introduced by AMD on February 7, 2020. The 3990X, which is based on their Zen 2 microarchitecture, is fabricated on TSMC's 7 nm process. The 3990X operates at a base frequency of 2.9 GHz with a TDP of 280 W and a boost of up to 4.3 GHz. This MPU supports up to 512 GiB of quad-channel DDR4-3200 memory.

[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.
