Doesn't matter what they call it when you think about it, the performance and cost of the chips it generates is all that really matters.
There are professional teardown/reverse-engineer outfits out there that basically dissect every chip that gets put out on the market - ChipWorks and Semiconductor Insights are the two more well known in the business.
You can bet they will cross-section TSMC's 28nm and determine whether or not it is superior to Intel's and GF's 32nm.
But yes, at the superficial node label level TSMC renamed their 45nm process node as the 40nm node, relabeled what was to be their 40nm half-node as now their 32nm node, and relabeled what was going to be their 32nm node (w/HKMG, etc) as now being the 28nm node.
All the node labels just took a half-node shuffle down the queue, if they didn't do this then it would have seemed like they (TSMC) had a sizable 18+ month lag behind Intel on 45nm which in turn would have been to their customer's disservice in product markets where their customers parts compete with Intel and GlobalFoundries customers.
It's all marketing. Totally harmless. I could care less whether TSMC releases their upcoming Ketchup node slightly after Intel releases their upcoming Mustard node, what is relevant to you and me is how well does GT300 shrink perform on TSMC's Ketchup node versus Larrabee shrink on Intel's Mustard node. (and
when do we get to find out?)
edit: Yeah it's Fudzilla, so you know apply usual caveats:
Globalfoundries to fight TSMC on 28nm
Who can get it faster, yield better
Sources close to Globalfoundries have informed us that TSMC won?t be the only company having the 28nm half node in early 2010.
