The BBAI doesn't count?

Sort of, but they tripled the price to take the CPU cores from 2010 (single A8) to 2012 (dual A15). I know the whole point of the BB is the real-time capabilities and the two DSP cores, but I do wish the application CPUs were faster. Now that there's compute support for the GPU in the Pi4, I wonder what the performance difference is (in AI stuff).

That's all fair. I love that the BB platform is so stable, I can design around it with reasonable confidence that my gizmo will still work in _another_ decade, which is a perspective only recently coming to the Pi world. But there are certainly sacrifices made in that approach.

Beaglebone AI was released: April 23, 2013.

Considering we're in early 2022, no. I wouldn't call that a refresh.

That's a typo, where did you find it? The BBAI announcement was February of 2019, and shipped in September of that year.

You are right, I was wrong. My apologies.

It looks like the date I quoted was the release date for an older variant of the beagle.
