Ryzen Embedded V1605B is a 64-bit quad-core embedded x86 microprocessor introduced by AMD in early 2018. This processor is based on AMD's Zen microarchitecture and is fabricated on a 14 nm process. The V1605B operates at a base frequency of 2 GHz with a TDP of 15 W and a Boost frequency of up to 3.2 GHz. This MPU supports up to 32 GiB of dual-channel DDR4-2400 memory and incorporates Radeon Vega 8 Graphics operating at up to 1.1 GHz.

This model supports a configurable TDP-down of 12 W and TDP-up of 25 W.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

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.
