I disagree with this bit:

Realistically, retention is not a problem for Intel since Haswell is a client chip that is unlikely to reach junction temperatures much above 80C, whereas IBM’s server processors must operate at far higher temperatures.


Client chips on the desktop seldom reach high temperatures, but mobile is a different story. I have temperature monitoring software on a 2011 MacBook Air (Sandy Bridge), and I've seen 90C or higher readings from CPU on-die sensors during heavy CPU load. (The i7-2677M CPU is rated at Tjmax=100C.)

SNB/IVB ultrabooks and other slim/light designs depend on permitting the delta-T between silicon and ambient air to grow as high as it can without exceeding Tjmax. I expect to see Haswell systems doing exactly the same. Nobody would be very happy with Haswell portables needing a significantly larger and/or noisier thermal system to keep GT3e eDRAM cool.
