I'd like to know how two 22nm processes(IBM's SOI and INTEL's TriGate) on the market compare, as far as I know those are the only two high performance 22nm nodes on the market.

Namely 22nm IBM SOI node it builds its Power 8 CPUs VS 22nm Tri-Gate Intel node

How do those node compare in terms of performance, density and power?

I think performance goes to IBM, why? Because the performance of 22nm process actually get worse compared to 32nm at the expense of power.
Density? I don't know
Power? Intel, due to its usage of Tri gate transistors.

What do you think? And how does TSMC's 20nm compare? Performance-wise it should lose to both and by a large margin. Is the drive current and other data available for those nodes?

Intel should be well ahead of IBM when it comes to performance and power. Intel has always lead... by a significant margin. Not quite so much against IBM's SOI, but the advantage is still there.

Density I'm not sure of. Usually IBM's a bit denser.

This is of course just speaking from historic trends. I don't know IBM's actual numbers for 22nm.

My reasoning for why IBM should have faster transistors at 22nm is that they would have to be somewhere around 5 years behind Intel earlier if they still didn't catch up. They would still have to be behind Intel's 32nm process which was released in January of 2010. Power 8 was made available 4 and 1/2 years later. Because with 22nm Intel took a step backwards in terms of performance that would mean Intel had an over 5 year lead in terms of transistor performance.

They're something like a year behind Intel for transistor performance. The other foundries are about 3½, IIRC.
