Even then, won't this be of little impact to practical performance benchmarks?

We are not talking about bypassing the limitation imposed by slow interconnect busses.

I've been out of the hardware scene for a while. Someone more-knowledgeable please correct me or back me up.

well, it's also going to save some power and allows larger amounts of memory. I'm just wondering why they would put it on the market in a month when nobody outside R&D labs has the hardware to use it yet.

Altera at the very least has FPGAs you can buy right now that offers DDR4 interfaces [1]. Also, I imagine a lot of this is directed towards OEMs who can get the early silicon samples of Haswell-E chips so they can start testing with them.

integrated gpus should benefit from additional bandwidth.

Anandtech has some fantastic articles on memory speeds and the impact on applications, such as http://www.anandtech.com/show/7495/adata-xpg-v2-review-2400-.... There are measurable differences, though they are "slightly pushing the edges" rather than being make or break.
