I work in (way smaller) embedded development, so I was curious about the low-level I/O capabilities. If you say "this SoC is for embedded", I am going to wonder about the SPIs, I2Cs, UARTs, and GPIOs.

I surfed up the "product brief" [1] which states:

• Up to 4x USB 3.1 (10Gb/s) / 2x Type-C® with ALT. DP power delivery capable

• 1x USB 3.1 (5Gb/s)

• 1x USB 2.0

• Up to 2x SATA ports

• NVMe support

• eMMC5.0, SD3, or LPC

• Up to 16L of PCIe® Gen3 (8 lane GFX, 8 lane GPP) and 7 link max

• 2x 10 Gigabit Ethernet

• 2x UART, 4x I2C, 2x SMBus, SPI/eSPI, I2S/HDA/SW, GPIO

So ... that's pretty good, then. No clear number on the GPIOs but I guess it will be at least "a handful" since these are no small packages.

My guess is the GPIO is similar to the 16 bits of the older G series SoC. I think it's more for led indicators, chassis intrusion, and the like. But the SPI and I2C make that kinda moot with all the GPIO and PWM or interface to a micro/cpld/fpga. In the end it's still more PC than microcontroller.

Side note: I've yet to see anyone using AMD's 10GbE ports nor any driver support in any OS for any existing AMD SoC board. Anyone know what's up with that?

I also found it odd that nobody ever talks about the NICs. I wonder if they're buggy or deficient in some way. STH said "We were able to pass 10Gbps of traffic through the NIC" so there is some software support. https://www.servethehome.com/amd-epyc-3251-benchmarks-and-re...

I wonder when we'll get a SBC with it.

"Ryzen-pi" sounds like fun!

Or Raspberry Rye.

Ryzeberry Pi

Ryzenberry has even better ring to it

Ryzberry Pi sounds even better IMHO

To me this (and the other ones) just sound too similar to Raspberry. You shouldn’t choose a name that could sound like a typo of something else.

Ryzenberry adds a sylable, so there is no ambiguity and the hard Z makes it sound more powerful, which it is.

The only issue I can foresee is you might need AMD’s permission for the name, because it includes protected trademark.

In Canadian, that sounds like a cursed beverage.

...said scooby doo?

plenty in pre production phase, including scam Atari VCS (R1606G)

The Udoo with Ryzen has been around for 2 years now. https://www.udoo.org/udoo-bolt-the-amd-ryzen-based-maker-boa...

It's not with this ultra low power embedded APU though.
