The new tri-gate transistor design is a big deal. With it and 22nm, Intel are literally doubling performance per watt in Ivy Bridge. That's staggering.
- hga 15y agoYeah, but with much the same microarchitecture there are limits to what they can do with that. The tick-tock concept is that they only try one hard thing at a time and moving to the new process node with the current microarchitecture is what's Ivy Bridge is about. If you look at what Intel did with Sandy Bridge when they obviously took advantage of what they'd learned in moving to that process node in the previous step you'll get an idea of how what follows Ivy Bridge is likely to knock our socks off. Hmmm, there's a further factor, economics: moving to a new process node is fantastically expensive and designing a new microarchitecture is not cheap. By limited how much the push the envelope in the former they can, if they get it right, allow the smaller dies with hopefully a high yield pay off the fab line investment.
