Oddly, the CPU never actually reports 6 that it is an “Engineering Sample” or “Qualification Sample” CPU, and you have to compare it to another CPU or prior knowledge in order to figure out that it’s not a retail chip. To be clear, this isn’t a guide to identifying an Engineering Sample CPU - it’s just picking apart some discrepancies that I could find by comparing my ES CPU to a similar CPU in an instance I rented on AWS.
