Intel Haswell-E De-Lidded: Solder Is Its Thermal Interface

Sorry for being about a month late to this news. Apparently, someone got their hands on an Intel Core i7-5960X and they wanted to see its eight cores. Removing the lid, they found that it was soldered directly onto the die with an epoxy, rather than coated with a thermal paste. While Haswell-E will still need to contend with the limitations of 22nm, and how difficult it becomes to exceed various clockspeed ceilings, the better ability to dump heat is always welcome.

While Devil's Canyon (Core i7 4970K) used better thermal paste, the method used with Haswell-E will be event better. I should note that Ivy Bridge-E, released last year, also contained a form of solder under its lid and its overclocking results were still limited. This is not an easy path to ultimate gigahertz. Even so, it is nice that Intel, at least on their enthusiast line, is spending that little bit extra to not introduce artificial barriers.
