We don't. They knew about the issue pre-release and released a known lemon, plan to sweep things under the rug, and nothing short of a massive hammer by class action or regulators will change their mind.
Intel is the Boeing of the computer world.
Current theory is the ring bus is getting cooked
Quote:
MLID's sources said that the "leading theory inside Intel right now" is that the Ring Bus is "getting cooked because it's fed the by the same rail as the P-Cores and E-Cores". Intel's 13th Gen Core "Raptor Lake" CPUs needed to hit incredible high voltages in order to "be competitive" with AMD's new Zen 4 platform at the time.
The first source of MLID says that "it seems like it was just pushed too hard" continuing that this is just an "inherent flaw that would be in Barlett Lake too IF it's overvolted". The source continued, saying that Meteor Lake "isn't affected".
The second source said: "I never worked directly on Raptor Lake (Intel Design Engineer), but I did have exposure to Alder Lake, and I can confirm that they were very concerned about the ring bus getting damaged if the voltage was pushed too high. I can also confirm that Raptor Lake was rushed through the design and validation process".
MLID's third source said: (Intel Foundry Services) can tell you that Raptor Lake was rushed through our Fab in Arizona in record time, but it's also produced in other fabs. However, this location (Arizona) is notable because I can confirm that there was an Oxidation issue by some failure in our HVAC system between March & June 2023. It was so bad that Keyvan Esfarjani had to fly in to make a decision about which wafers (which cost as much as Model X each) needed to be thrown away. To be clear, I don't know what decision was made, but I do know that this event DID happen. And by the way, it affected Sapphire Rapids yields as well, although I doubt it's an issue wasn't fixed by now".

How many chips does Intel estimate are likely to be irreversibly impacted by these issues?
Intel Core 13th and 14th Generation desktop processors with 65W or higher base power – including K/KF/KS and 65W non-K variants – could be affected by the elevated voltages issue. However, this does not mean that all processors listed are (or will be) impacted by the elevated voltages issue.
Intel continues validation to ensure that scenarios of instability reported to Intel regarding its Core 13th and 14th Gen desktop processors are addressed.
For customers who are or have been experiencing instability symptoms on their 13th and/or 14th Gen desktop processors, Intel continues advising them to reach out to Intel Customer Support for further assistance. Additionally, if customers have experienced these instability symptoms on their 13th and/or 14th Gen desktop processors but had RMA [return merchandise authorization] requests rejected we ask that they reach out to Intel Customer Support for further assistance and remediation.
Will Intel issue a recall?
No.
Has Intel halted sales and / or performed any channel inventory recalls while it validates the update?
No.
