OK, looks like there is still lots of misinformation out there. anandtech.com has a full rundown on IB procs from the IDF last week. We can expect performance quad cores at about 40W, and i7's at 65W. Expect an approximate 10-15% increase in performance over SB as it is SB architecture but with a die shrink and some added instructions. The HD graphics should be an approximate doubling over SB as they have switched over to an architecture which (according to anandtech) is very similar to what AMD/nVidia uses.
Haswell will be a new architecture, which generally means a 20+% improvement if we compare to other new architecture releases.
The GPU on Haswell (2013) will be a rough equivalent to AMD's current (2011) on-die graphics solutions, which means Intel will still be behind, but catching up. By Broadwill (2014-5?) (the Tock of the Haswell Tick), they think they will have a comparable on-board graphics solution to AMD. Now, with that said, the current HD graphics are more than enough to run most programs, and quite a few games at decent quality, and at OK resolutions. If you want a gaming rig you will always have to buy a discreet graphics card because we should have cards capable of real time ray tracing on the high end in the next 2-3 years. None of the on-board graphics options will come close to that.
And for the Bulldozer fan boys; The reason TDP is so important for performance parts is for one simple reason: By the time Haswell comes out, you will have performance chips that can run on a netbook battery, while AMD may still be serving mainstream chips at a similar wattage. That is going to seriously cut into AMDs current mobile superiority (which really isn't that far behind Intel to begin with). I love AMD, they have been a great company in the past, but AMD is a wildcard. Intel is on a road map they have stuck to fairly well the last 3 years, and has another 2 years to go on. We know exactly what to expect, and roughly when to expect it (give or take a few months). AMD the last few years has talked big, but delivered little. Now they are not talking at all, and we don't know what is coming next. With no game plan, companies cannot make plans (kinda like economic policy), and if a company cannot make plans around your product then they will not use your product.
AMD can turn this around, but will they?
