However I would honestly like the 1800X to ship with a 120W+ TDP. It is hardly unreasonable for a high-clocked octacore CPU, especially when AMD will also offer more energy efficient options. Although having said that, it remains to be seen what the actual power draw of these chips are; TDP is barely more than a marketing number these days.
