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.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
