DC-ROMA RISC-V AI PC, RISC-V Mainboard II for Framework Laptop 13

Was really surprised to see this! Especially a vector-instruction compatible AND out-of-order processor. Does anyone have any idea exactly what chip it uses?

It's does not! RVV support is only on the DSP (I asked them), and I'm personally not sure even that is true, as the EsWin EIC7700X DSP has a cadance XTensa chip.

Heh, I just came from Reddit where I saw your post, and was about to update my comment.

Yeah, it seemed strange since to my knowledge no out-of-order vector RISC-V chip exists at the moment.

Interesting, hopefully DC can fix their advertising/clarify a bit more!

Terrible, doesn't even specify the SoC used, or the CPU core.

Thus must assume it is the K1 because that's been available for a while in other boards and meets the description.

The K1 is fairly slow (e.g. slower than even VisionFive2's JH7110), thus not very interesting.
