    8-bits?!? Geez, that must be one crappy furnace.. I need 64-bit 8-core APU with 16GB of RAM, 4TB SSD and double-floating-point precision and temperature resolution up to 12 decimal places.. Needs to poll the current temperature 1000 times per second.. It would need its own cooling system actually and be loud as hell.. But boy would my neighbors be jealous when I can watch game of thrones at 4k on my 2-inch display..

      of course it does need 64-bit. x86_64 is faster and more power-efficient than x86. and it does not take measurable die space

          Yep. I was just making point that performance is not always top priority. There are plenty of embedded appliances that run linux and doesn't need performance of full blown x86_64 processor. For instance i work with EFT terminal verifone MX900 which is linux powered. I doubt that processing your credit card transaction takes a lot of processing power :P
