Well, I imagine the numbers would be even worse on stock images, given that the vendor SDK restricted the 512-bit MXU3 instructions to only run on the first core, if I recall?

The NNA lives outside the MXU3 extensions. On the stock image, they're using 4-bit layers for a big chunk of the inference, and they're actually getting really good framerates (the actual numbers escape me atm). That was always a future work step for me.
