These people are braindead though.
Literally getting a new technology and going pompously pointing fingers and throwing shade at the creator of the new tech for "not mitigating" well enough.
Hey genius, that's what being NEW is. We don't know the mitigations because they're new. That's the entire concept of "new", or "unknown" or "innovative" or really anything that isn't just walking the same inroads we've been doing for 15 years. Ignoring instruction sets, 3D Vcache is probably the first very big CPU improvement since multi core.
And here we have these Holy Judges passing their Holy Judgement on AMD for their users playing around with a completely new tech and not somehow magically guessing how to stop them doing something stupid before they even do any of these things.
Well, that is quite boring.
I mean it's safe and all, sure. But boring.
if you make a widget that i buy from you then my expectation as the consumer is that it should perform as advertised meaning any feature that i as the consumer have access to can be used unless otherwise spelled out as a warning.
If you squeeze in some feature that i am not supposed to use because it blows up your product and you dont label it appropriately then its not my responsibility as a consumer to figure this out for you. My responsibility ended when i paid you the money. It is yours as the vendor to properly advertise your product and take all the safety precautions needed to minimize issues . Its as simple as that.
Things like XMP/EXPO, performance tunning features, etc should be clearly labeled as warnings that your chip can blow up if thats the case. On the right hand side in the description section, every of those features should state "WARNING - may cause permanent damage to the hardware if enabled" . So that i as the consumer can make that decision - do i wanna risk blowing up my chip for 5% perf? Yes/No.
But no vendor does it and you know why? Because not worth the potential loss in sales due to less than advertised performance, not widespread, and probably requires too much time to proofread (looking at you gigabyte).
So if this person enabled EXPO and blew up his chip....i dont see how thats the consumers fault. Has nothing to do with being new or innovative or being braindead whatever...it is an additional cost/investment with very little return that manufacturers deemed not worth it at your expense as the consumer.
