Intel is undoubtedly at the forefront of silicon processing technology these days, and has been for a long time. Being a fully integrated company from the bottom up, through the design and actual production of its silicon semiconductors, really does have a way of either paying of tremendously (as has been the case with Intel), or not at all (as was the case with AMD). That fabrication processes' nm ratings don't mean much in thhe industry right now has been the case for a while now; different companies use different calculations towards achieving a 22 nm or 14 nm claim, with some components in the same nm process having almost double the size of the same components in a competitor's equivalent. Intel has always been one of the more adamant defenders of an industry-wide categorization, both to avoid confusion and - naturally - put into perspective their process leadership.
