Athlon PRO 300GE is a 64-bit dual-core low-end performance x86 workstation microprocessor introduced by AMD in late 2019. This processor is based on AMD's Zen+ microarchitecture and is fabricated on a 12 nm process. The PRO 300GE operates at a base frequency of 3.4 GHz with a TDP of 35 W. This MPU supports up to 64 GiB of dual-channel DDR4-2666 memory and incorporates Radeon Vega 3 Graphics operating at 1.1 GHz.

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.
