We recently got our hands on a Core i7-4770K, based on Intel's Haswell micro-architecture. It’s not final silicon, but compared to earlier steppings (and earlier drivers), we’re comfortable enough about the way this chip performs to preview it against the Ivy and Sandy Bridge designs.
Presentations at last year's Developer Forum in San Francisco taught us as much as there is to know about the Haswell architecture itself. But as we get closer to the official launch, more details become known about how Haswell will materialize into actual products. Fortunately for us, some of the first CPUs based on Intel's newest design will be aimed at enthusiasts
Looking at the chart they have, it really isn't a big jump or much of a jump at all over Ivy or Sandy bridge. But then again Intel whole business plan has changed. They are no longer looking to make the most powerful CPU, instead they trying to get into the cell phone market, because as of now, they are the only CPU maker who isn't in the cell phone market. Therefore Intel is more interested in making things that use less power for it can provide a much longer battery life for smart phones and tablets.
Either way, it will just make the price of Ivy and Sandy even cheaper. Not a fan you going to need a new motherboard to run Haswell though because Haswell will use 1150 socket.
