Ryzen 7 3780U Microsoft Surface Edition is a 64-bit quad-core high-end performance x86 mobile microprocessor introduced by AMD in October 2019. This processor is based on AMD's Zen+ microarchitecture and is fabricated on a GlobalFoundries 12 nm process. The 3780U operates at a base frequency of 2.3 GHz with a TDP of 15 W and a boost frequency of 4 GHz. It supports up to 32 GiB of dual-channel DDR4-2400 memory and incorporates Radeon Vega 11 Graphics operating at up to 1.4 GHz.

This model supports a configurable TDP-down of 12 W and TDP-up of 35 W.

Cache

Main article: Zen § 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.
