Ryzen 9 4900HS is a 64-bit octa-core high-end performance x86 mobile microprocessor introduced by AMD in early 2020. Fabricated on TSMC's 7-nanometer process based on AMD's Zen 2 microarchitecture, the 4900HS operates at a base frequency of 3.0 GHz with a TDP of 35 W and a Boost frequency of up to 4.3 GHz. This APU supports up to 64 GiB of DDR4-3200 or up to 32 GiB of quad-channel LPDDR4x-4266 memory. The 4900HS integrates a Radeon Vega 8 Graphics operating at up to 1.75 GHz.

This processor is a lower-power version of the 4900H, featuring slightly lower base and turbo frequencies.

Cache

Main article: Zen 2 § 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.
