I'd bet that they've moved specific video functions to fpga's (rather simple since they have all the code already) and are using generic ARM/whatever cpu's for the more mundane SoC stuff.Last edited by milkylainen; 19 March 2018, 01:11 AM.

The day I first installed Linux was the day I learned my computer actually had a 64-bit processor...

But I was talking of embedded devices, like routers and NAS and cameras and IoT and whatever. Most of these things have between 32 and 256 MB of RAM and aren't running particularly heavy software in the first place.
These devices still have and use 32-bit processors or have 64-bit processors run in 32-bit mode to save RAM and because it's just faster to keep using their legacy software stack that was 32-bit.

Is it time to stop developing Desktop systems with 32-bit CPUs? Yes. Absolutely.
