Showing Ivy Bridge this early is a bit silly in my honest opinion. There are people out there who don't believe Sandy Bridge is a big enough improvement over Nehalem and they're only going to wait for Ivy Bridge before parting with their money.
If AMD's on the ball, Bulldozer will have been on the market for a few weeks before the demonstration. If not, well... never mind.
Ivy Bridge looks to be just a way of getting 6 or more cores into the space formerly afforded to 4 cores on the 32nm node. Aside of having extra cores and a lower manufacturing process, the CPU side of Ivy Bridge doesn't sound any more powerful. If they want to keep power and heat under control with the additional cores, they can't realistically clock it too highly.
I'd like to know what Intel are doing to increase Ivy Bridge's performance on a per-core basis, if they are at all. They're also probably not worried about Bulldozer as concerns the desktop space; even if it ends up being an integer crunching monster, that's not so useful on the desktop, and as it doesn't appear to offer a significant floating point boost over Stars, it's likely to fall short on that side of things, at least with the first generation. It's the server market that may just provide AMD with the most wins.
I hate waiting for Bulldozer. I just want to see how it stacks up with Sandy Bridge.
