That's completely besides the point. How long does an embedded linux box need to get it's GPU up and ready for number crunching? But yes, FPGAs are best-suited

That's completely besides the point. How long does an embedded linux box need to get it's GPU up and ready for number crunching? But yes, FPGAs are best-suited for deterministic low latency stuff. With the jetsons (agx orin) I have on my desk it would take a bit of tinkering to even get it under a minute.
