It's better to avoid all RPL. FTFY. Especially since Intel thinks price increases on them were a good idea.
I was listening to the hardware unboxed podcast and Steve has re-tested raptor with a bios from before the mitigations started rolling out, against the latest. 10% performance loss in cinememe, 5-10% in games for an average of 8% performance loss compared to launch. He pointed out, that's sometimes a generation worth of performance loss.

I'd also like to know how that degraded CPU made it to being for sale at CEX. Was it a (broken) pull from a trade-in PC?

Of the components CEX buy and sell (so CPU, RAM, GPU, SSD etc. but not motherboards, PSU and similar), they seldom do much testing. Sometime even zero testing.

I guess historically, CPUs seldom failed so this is a bit new for them. I guess this a good way to tell how much their 5 year warranty is actually worth, though!

Edit: added "buy" to make it obvious that cex4 basically but and sell used parts etc.

But are 2nd hand CPU are in warranty?
If you had watched the video 📺 Iceberg shows that CEX offers a warranty on everything they sell.

Thanks for the info. Makes sense that if it made it past POST they'd check the box for working/good or whatever. The warranty is there for if the defect is less obvious, like in this instance.

The way CEX operate is to buy things from the public - either for cash or CEX vouchers and they offer quite a bit more in vouchers to get you tied to them - and sell that back to the public in their shops.

While they're are pretty good at testing and grading phones and other electronics, for computer parts they sometimes don't even have a test rig.

For anyone who has ever been in their shops, their whole test area is usually a small corner with shelves and a bench which is at most 1m wide. And that space is for testing everything.

Still they've been in this business for ages so they most have some procedures just sometimes things fall through. Plus some shops are theirs while some are franchises AFAIK - unsure whether that too affects testing.

3 strikes, you're out. Client had better at least be agreeing to swap boards to a retail model that is fully mitigated for yet another replacement 14900K.

Corsair wants to quit the market, no? Like Asrock they tends to fry processors and ruin the builds.

Hmm, while Corsair should have most blame (for not providing mitigation updates) it seems the root here is still that the CPUs need mitigation updates to survive (on basically every board).

While this is completely true that it needs mitigation, intel has supposedly provided the mitigation. So, at this juncture, I put the blame on Corsair. If they provide it and the CPU still degrades, we're back to intel. The supposed mitigation has been available for a while now. There's no excuse for a BIOS provider to have not provided it.

Intel for now is saved since they gave the mitigation tools, the issue is Corsair. They had a LOT of time to implement the change, not giving the solution, makes them really the culprit.
