You seem to be trying to litigate this on Hacker News, which is does not have the authority to issue you a refund. If you feel strongly about this, sue Intel. Most of us will not be joining you because we either rent CPUs from Amazon or are out a tiny amount of money for our personal rigs. Yup, this is "how they get you" and someone should be a check and balance on a defective product. But, most of us have no appetite to spend years or decades litigating this. We accept that our $200 wafer of silicon with 13nm features that can execute billions of mathematical operations is "good enough". Sometimes there are bugs. But we don't know how to make these things ourselves, so we deal with them and aren't really looking for a pound of flesh from Intel because the billions of instructions their CPUs can execute per second is a slightly lower number of billions.

Part of the initial stages of a class action is verifying that there does indeed exist a class.

There's value in him talking about his grievance publicly and not just rolling over when he gets screwed by a corporation, just because that can beat him one on one in a legal brawl.

I also can't build a modern car. Or insulin. Or a million other devices in my life. The bar isn't "you can only complain if you can make it yourself better", it's "you can complain if what was sold to you didn't meet it's advertised specifications".
