*** it, getting a haswell i7 and new mobo. -.- The fx series has been nothing but a nightmare. Here's to hoping broadwell wasn't worth waiting for anyway.
from what we know so far, they'll have a more efficient TDP by a magnitude of 4 times; ergo, they'll run much cooler with much less heatsink capability... exactly four times less heat dissipation required. it's also going to be using a more efficient transistor arrangement in order to meet the requirements of a 14nm manufacturing process, and on a less interesting note, will reduce motherboard sizes by about 25% or allow motherboard manufacturers to pack in more goodies for almost the same cost as current boards.
they'll be similar to Kepler -> Maxwell; far more power and heat efficiency in addition to much higher overheads on performance. also cheaper DDR4 support
