IoT and super-fast 5G mobile broadband?
Hilarious. 5G doesn't really exist. Unlike 2, 3g & 4G it's more about a flexible infrastructure and higher level protocols than the "air interface" or Modem Chips.
Intel has already "lost" the IoT market, which is mostly bonkers stuff no-one wants. How many TV,s Routers, WiFi points, setboxes etc use Intel?
The power issues when there is no screen and GPU even more favour ARM in embedded computers. MicroChip bought AVR, they and NXP produce 50cents and cheaper ARM based SoC. I can't see x86 or Intel in that market.
Memory chips :) That's what they did before the 4004!
