what is the consensus on how this would compare with the AMD Fusion?
Which one.? This is a stupid question with an obvious answer right now, but in a few months it wont be, when there are 2 totally different "Fusion APU's" on the market.!
The current one is a direct competitor of the Atom/ION, the next one to be released is the "average desktop chip", this is the chip that will compete with the "i3's" and "i5's".
In answer to your question, we already know how they compete with the current "E" series, but what about the "A" series. In some areas, I know for a fact that there wont be a competitor, in others there should be a great battle, and likely both sides will claim to be victorious - and often they are, it mainly depends on the testing and the system setups that are used - which again, will have to be re-written, and no-doubt will be re-skewed in favour of someone with cash in a brown envelope (not that I am suggesting that anything underhand ever goes on when performance testing computer equipment at certain websites #cough# toms #cough#).
AMD will with the graphics hands down, they will also win the price (maybe not the first month or 2, prices always need to settle), likely the price/performance will sway AMD's way, the outright performance on the CPU side is in the air, as is the efficiency - especially when the 9xx series of chipsets hit the market.
This should be interesting to watch.
