Athlon PRO 300U is a 64-bit dual-core value x86 mobile microprocessor introduced by AMD in early 2019. This processor is based on AMD's Zen+ microarchitecture and is fabricated on a 12 nm process. The PRO 300U operates at a base frequency of 2.4 GHz with a TDP of 15 W and a Boost frequency of 3.3 GHz. This APU supports up to 32 GiB of dual-channel DDR4-2400 memory and incorporates Radeon Vega 3 Graphics operating at up to 1 GHz.

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.
