Path to 2 nm May Not Be Worth It
What &quot;exactly&quot; is the reason that road to 2nm may not be worth it? I don&#x27;t see the article makes any answer to it.<p>Qualcomm are comparing 10nm and 7nm, and those figure are not as high as a generation node should be, and that is perfectly fine because 10nm from TSMC are half node. They should be comparing 14&#x2F;12nm with 7nm, and there are multiple iteration of 7nm. Does it scale as perfectly as before? No.<p>It isn&#x27;t about the complexity and design rules. It is about all about cost, and it only means chips are going to be more expensive going forward and only few companies will be able to afford it, but there are nothing on the roadmap suggest 2nm isn&#x27;t worth it.<p>This article reminds me of the old days 10 to 15 years ago when they keep saying the end of Moores law.
