This might be a great board to run Frigate NVR on.

I recently purchased an Intel N100 mini PC with a Coral TPU. Its performance with Frigate has been fantastic.

The major difference is the NPU in this RISC-V chip is much more powerful than the Coral TPU. It's NPU has the same TOPS as the latest AI hat for Raspberry Pi 5, but unlike the Raspberry Pi 5, it also has H.264 and H.265 video transcoding. The larger form factor might be a downside, but maybe not if expanded storage or reusing old hardware is a priority.

Note that on general code this should come in a little faster than a same-MHz (1.8 GHz) Raspberry Pi 4 / 400, or other Arm A72 board.

Unless your code makes use of NEON (or SSE/AVX on the N100). This CPU has no SIMD capabilities. The next generation of (not yet available in hardware) SiFive cores (P670, X280) do, as does the SpacemiT K1/M1 chip that is in a number of boards now e.g. Milk-V Jupiter, but has a lower-performance in-order core similar to Arm A55.

It's not going to be anywhere near the speed of a Pi 5 or the RK3588 boards such as Rock 5 or Orange Pi 5.

On my Primes benchmark (https://hoult.org/primes.txt) a 1.4 GHz P550 machine came in at 11.54s, half a second faster than a 1.5 GHz Pi 4 running 64 bit code. I'm expecting the 1.8 GHz boards to come in around 9.0s.
