For me, Pi6 shall focus on NPU to run edge models instead of getting into minipc space, e.g. 10TOPS built-in, that will be slightly better than Rockchip 3588 which was produced 4 years back at 6TOPS, and way more powerful than NXP's 2TOPS. 10TOPS is the sweet spot for edge AI as far as I can tell.
Designing a chip for one person is doomed to fail as a business.
