Kris, many devices are tested 100% at their hot temp spec. I don't know if AMD does this for this particular product, but I am sure that they would have charactized it at hot temp. This problem may have occurred due to a bad thermal design of the laptop computer. I doubt that the chip does not meet its temperature specs. Reliablity is looked at as a long term effect. You may have one or two fail out of a million but only after many hours of use. This sounds more like a systemic issue that causes all of the devices to fail.
How do you test for heat tolerance? You can take a sample from a lot but you are not going to test every one...none of the IC sold can be viewed as 100% reliable in general, there is no such thing as certainity in silicon! Kris
Yes, you would expect to see one other OEM chiming in if AMD made a defective CPU product. Then again, if Quanta "under-spec'ed" their thermal requirements, AMD may have sent them exactly the chips that binned out to Quanta's specification.
Blog Doing Math in FPGAs Tom Burke 14 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
