Hello Broadwell
 

Interesting read if you are so inclined. ;)

Introducing Intel's 14nm Node and the Broadwell Processor - tom's HARDWARE

Also covered on Anandtech, which I tend to prefer for this sort of thing:

Still just in previews, so no real benchmarks, and the big push is on power consumption and thermals, not on new performance.

For those looking at super-skinny hybrid systems, worth waiting for. For general use, or power users, probably not worth waiting for.

Word is that DDR4 is waiting for Sky Lake so practically inexpensive 16GB dimms probably are delayed for that for those who need 32GB and don't want a tank like the W540/E4800 (or want a tank to be able to take 64GB) and I doubt we're going to see a major bump in performance (either IPC or clock speed) or a 6-core laptop in the Broadwell generation.

Could be wrong; the Sandy Bridge->Ivy Bridge bump was expected to mainly be about power/thermal and the performance bump was pretty dramatic for a tick (frankly, more so than the "tock" to Haswell, given the bump down in clock speeds on a lot of the Haswell parts.)
