I've had the opportunity to test a bundle of CPUs of the same model (from Ivy Bridge E series), and have found a very odd variation in stock thermal performance when running Prime95: the average CPU is running about 55C maximum (most of them are around this), while one hot one was in the low 60s, and one extremely cool one was running mid 40s. I realise there is a silicon lottery, but this seems like a crazy variation: the hottest chip has almost double the deltaT of the coolest chip.
I thought the cool chip might be running crippled somehow, but it gets more or less exactly the score it should get on Cinebench.
Any ideas what's going on here?
