While INTC ceratinly isn't wanting for challenges, and TSMC is producing smaller die chips that Intel now (finally, hopefully) says it's 10 nm chips will be available by the holiday season of 2019, there was a story today about INTC making some breakthroughs in 'stacking chips', which they've been working on for 20 years which, if successful, would catapault them into being the leading-edge chipmaker again, given the versatility of the hardware. At least, so they say.
