>> I was thinking AMD Renoir but Zen 2 and RDNA 2 is an odd combination. Is it custom?

I don't recall any APU with that combination. The 5700G which is due next month is Zen 3 with Vega graphics.

Personally I don't care much about RDNA 2 but I would like the hardware AV1 decoder.

This seems like the rumored AMD Van Gogh for low power configurations: Zen2 CPU + Navi2 GPU. Essentially it's AMD's stop-gap solution before the launch of Rembrandt (Zen3 + Navi2). https://www.tweaktown.com/news/78815/amd-van-gogh-apus-zen-2...

Also agreed that this looks very price competitive. Given storage is SSD-expandable, $399 gives you a fairly powerful mobile gaming platform and PC.

SSD is soldered in

I've heard it is then later I heard it's actually expandable somehow. So who knows.

From the hardware section on the website.

Yeah, probably. Kinda like a Xbox Series/PS5 CPU lite.
