Microarchitecture

Ryzen 9 4900H 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 4900H operates at a base frequency of 3.3 GHz with a TDP of 45 W and a Boost frequency of up to 4.4 GHz. This APU supports up to 64 GiB of DDR4-3200 or up to 32 GiB of quad-channel LPDDR4x-4266 memory. The 4900H integrates a Radeon Vega 8 Graphics operating at up to 1.75 GHz.

The 4900HS is a lower-power version of this processor, featuring slightly lower base and turbo frequencies.
