Ryzen 7 PRO 5850U is a 64-bit octa-core high-end performance x86 mobile microprocessor introduced by AMD in March 2021. Fabricated on a TSMC 7-nanometer process and based on AMD's Zen 3 microarchitecture, the PRO 5850U operates at a base frequency of 1.9 GHz with a TDP of 15 W and a boost frequency of up to 4.4 GHz. This APU supports DDR4-3200 or LPDDR4-4266 memory and integrates a Radeon Vega 8 GPU operating at up to 2.0 GHz.

Compared to its mainstream counterparts, the PRO 5850U includes a set of enterprise-oriented features such as Memory Guard, image stability, software stability, and manageability support.

[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.
