Yeah it would be awesome to get a PC with DDR4. I jumped in on DDR3 at the beginning of its lifecycle and wouldn't mind doing so again for 4 :P

One downside - we'll need new motherboards for these rams. For people who are still with Ivy Bridge, Sandy, or even more Nehalem, a change to new Broadwell cpus (when they come) from Intel + new motherboard and ddr4 ram, it would be awesome and well worth.

Not really a problem considering Intel makes a new socket every other year and Steamroller might be AMD's last DDR3-only architecture. Personally, I think the move to DDR4 is dumb - we might as well skip to DDR5, seeing as how we have the technology to do it and the move is inevitable. I guess companies moving to DDR4 helps increase sales of products. What I think would be nice is if they only made SO-DIMMs for DDR4. It'd save room on full-size motherboards and RAM could be more easily interchangeable. Lets also hope AMD moves to triple or quadruple channel. I think they lose a lot of potential by sticking with dual channel.

Hey maybe i will upgrade my aging build when DDR4 hits I should see huge leaps in performance by then. DDR3 is lower timing and GDDR5 is much much higher timing and higher bandwidth and I guarantee DDR4 still have much lower timings then GDDR5 the 2 cant be compared for same purposes. GPU benefit from the higher bandwidth more then then the lower timing and system benefit more from lower timing then the bandwidth which why its dont use gddr5. GDDR5 is off variant of DDR3.

DDR4 won't allow multiple DIMMS per channel as I understand it, at least not in the traditional sense, so expect A) more channels and B) larger DIMMS (capacity wise). 128 GB RAM please 😀

in the future we're gonna look back at all this motherboard swapping and realize how ****ed we've been getting. new cpu? better get a new mobo! new ram? better get a new mobo! zzz
