Back in the day, CPUs were sold to run at an optimum work point, meaning a compromise between silicon wafer yield, power consumption and performance. Some of the chips were so good, they had the potential for overclocking, meaning they are stable enough to be clocked higher and to handle the heat. (But at no guarantee from the manufacturer, I presume. So if you grill it, it’s your loss.)
I remember one supplier, can't remember exactly the details, but it was something like "we supply overclocked chips to save you money. If you fry your chip within (18 months it might have been) we'll replace the chip with one spec'd at the higher price".
They'd done the maths, and it was something like the chip would probably survive the warranty, and once the warranty expired, chip prices would have fallen to the point the customer could use the savings and replace a failed chip. Win win ...
