We’re not likely to be running DDR4 any time soon on desktops, and even most laptops are probably over a year away from getting the upgrade, but now is the time to prepare for the shift. To that end, Micron (Crucial) has a DDR4 demonstration running at CES 2013. The system is an Intel test platform with undisclosed internal hardware, affectionately (or perhaps not) referred to as the Frankenstein Box. My guess is that there might be an Ivy Bridge, Sandy Bridge-E, or current-gen Xeon running in the box with a converter board of some sort to allow the DDR4 to talk to the DDR3 on-die controller (similar to the RDRAM to SDRAM converters we saw back in the Pentium 4 Rambus days), but how they’re running it right now isn’t particularly important so much as the fact that they are able to run Windows. It’s just as possible that the box has an unannounced next generation Xeon with a DDR4 controller.
