The 10nm chip Intel sold last year was bullshit -- low volume and single SKU because it wasn't anything to write home about.
People also keep trying to defend Intel by saying their 10nm is roughly equivalent to the TSMC 7nm, but that's a pretty BS defense seeing as Intel hasn't shipped a real product with it.
Meanwhile TSMC is already working out the kinks on their 5nm process for next year. No matter how you slice it, Intel has fallen behind.
