• One interesting point to note is that even though the Q6600 is essentially 2 x E6600, the TDP is not doubled, but rather sits at a comfortable 105W. The higher clocked QX6700 is 130W, however, which is why we don't see a QX6800 instead. A TDP of 130W is high to begin with, but considering the much slower 820 D we reviewed less than a year ago also had a TDP of 130W, power consumption still hasn't entered uncharted territory, and there are thermal solutions available to deal with that kind of heat.Below, you can see a highly detailed illustration of the quad-core's innards. In case you thought that two dies would be a tight squeeze, think again! Despite having four cores, there's still a reasonable amount of breathing room in there.
