What’s the reason for this? From my understanding of numbers, 10 is not 7
- std_throwaway 9y agoThey are measuring different things and use different transistor designs.
- raugustinus 9y agowell yeah not really. it's a bit of a long read but it comes down to whom you ask. https://www.extremetech.com/computing/246902-intel-claims-three-year-advantage-10nm-process-wants-change-define-process-nodes https://www.extremetech.com/computing/246902-intel-claims-th...
- mappu 9y ago"10nm" and "7nm" are marketing terms that are not directly comparable across foundries.
- colejohnson66 9y agoHow? I thought the number was the size of the smallest transistor?
- Valmar 9y agoThe numbers are almost pure marketing, these days. From https://en.wikipedia.org/wiki/7_nanometer#7_nm_process_nodes https://en.wikipedia.org/wiki/7_nanometer#7_nm_process_nodes > The naming of process nodes by different major manufacturers (TSMC, Intel, Samsung, GlobalFoundries) is partially marketing driven and not directly related to any measurable distance on a chip – for example TSMC's 7 nm node is similar in some key dimensions to Intel's 10 nm node.
