Ryzen Embedded V1780B is a 64-bit quad-core embedded x86 microprocessor introduced by AMD in December 2018. This processor is based on AMD's Zen microarchitecture and is fabricated on a GlobalFoundries 14 nm process. The V1780B operates at a base frequency of 3.35 GHz with a TDP of 45 W and a boost frequency of up to 3.6 GHz. This model supports a configurable TDP-down of 35 W and TDP-up of 54 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.

Expansions

This processor supports up to 16 PCIe Gen 3 (8 GT/s) lanes, 8 GFX and 8 GPP lanes in mixed x8/x4/x2/x1 configuration with a maximum of 7 links total. Two GPP lanes can be configured as SATA 3 (6 Gb/s) ports, other alternative functions are 2 × 1/2.5/10 Gigabit Ethernet and NVMe. Six USB ports are available. Four ports support USB 3.1 (10 Gb/s) speeds, two of these support Type-C connectors with DisplayPort Alternate Mode and Power Delivery capability. Two additional ports are USB 3.0 (5 Gb/s) and USB 2.0 compliant, respectively. The following low speed interfaces are available: eMMC 5.0, SD/SDIO 3.0, 2 × UART, 4 × I2C, 2 × SMBus, LPC, SPI/eSPI, I2S/HDA, GPIO.
