The Amlogic S905X3/4 are "jelly bean" chips under this definition - you can buy full computers with those including a motherboard of sorts, RAM and standard USB/HDMI/Ethernet/eMMC/Wifi for under $30 bulk in China. They're branded as "TV boxes". The S905X3 is also the SoC of the $55 Odroid C4 SBC.
Yet those chips are apparently made on either TSMC's or GloFo's 12nm nodes (which one I can't find). Whilst Intel's 14nm is still superior to either TSMC/GloFo 12nm by all accounts, they're definitely the same ballpark. Competition for Intel even looks rough for cheaper high volume chips. You'd need to consider that Intel still needs some time to adapt to being a third party foundry too.
