MTL-S got canned coz they got more performance out of RPL-R. Doubt they could've gotten more out of ADL refresh unless they ported it to Intel 3. They failed miserably with Rocket Lake in their pursuit to win benchmarks. IDF saved them with Alder Lake. Then they tried to coast along on that design by souping it up with more cache and higher clocks. That failed miserably again as we can now see. It seems Intel's desperate attempts at winning benchmarks are consistently blowing up in their faces. My advice to them would be to stop trying so hard and just do what they hired people to do in the first place.
You're missing context such as being behind in process tech. You can't design your way out of node with half the density and lower perf/watt than your competitors while keeping up in performance.

It's not as if they're pushing to insanely high clocks relative to their competitors. When RPL first launched it was competing against Zen 4 that clocked up to 5.7ghz, the 7950X fmax is actually 5.85ghz under the right conditions - this is very similar to the original RPL that had TVB boost clocks of 5.8ghz. For the lower end SKUs, they clocked lower than their AMD equivalent (The 7600X/7700X has higher clocks than the 13600K, the 7900X has higher clocks than the 13700K). My point being that it's not as if the original RPL had some unprecedented boost clocks.

Edit: A contributing factor to this fiasco could be that RPL didn't have the typical product cycle. It was cobbled together in a hurry once it became apparent that MTL wouldn't be ready for Fall of 2022. The development time for the RPL lineup was considerably shorter than it was for ADL.

That PCIe error may actually be CPU-related...
Yes, it may. But then again it seems to vanish - for some time - after a Clear CMOS even after loading my old BIOS settings afterwards. And I am willing to put all the blame for possible PCIe based BIOS corruption on Intel XTU's watchdog hard crashing the PC "as a failsafe if anything happens during tuning".

I will do another TFD tutorial run without skipping the movies now.

Watch a degraded 13900k crash running intel extreme tester in a couple of seconds. Time coded to 2m18s.
That's a very transients heavy and thus demanding test, basically as if you were switching Prime95 SFFT AVX2 on and off all the time within milliseconds. I like that and will add it to my test arsenal in the future to accompany the other transients heavy tests I like to use on top of the usual "constantly high load" suspects (P95, OCCT, Yc etc).

I looked more closely. This is run with a zero AVX offset, so you are watching a considerably AVX overclocked 13900KS crash in a very demanding test. The (BIOS on "Auto") stock AVX offset on my 13900K is -5. He is running a KS at 5.6 GHz with no offset, that would be 56 vs. 57-5=52 aka 400 MHz higher than stock.

In fact I just had to change my AVX offset from 1 to 2, because 1 didn't pass the XTU test without blue screen, despite running stable in every other test I threw at it (including ones that likely no one else does). This runs my 13900K at 54/54/55/55/54/54/55/55 for all-core load then.

"until Intel puts out a better statement, we simply do not feel comfortable recommending 13th and 14th Gen CPUs while this matter is pending"

Boom!

I asked one of Tom's writers (on Twitter) why they, as a consumer site don't take this stand, and recommend consumers to stay away from these processors. He said (at the time) they would not, but I had a feeling they have considered it.

And now, after GN statement, the dam may break.

New GN video with some more leads:

"until Intel puts out a better statement, we simply do not feel comfortable recommending 13th and 14th Gen CPUs while this matter is pending"
Tinfoil time... I wonder if Intel is keeping quiet until after the AMD 9000 series have been reviewed. Reviewers have to run the Intel cpu's at stock even if the cpu's have a known issue at that performance level. At best the reviewers can put big fat question marks next to the Intel results.

To be fair, most of Tom's writers probably don't understand CPUs well enough to give good commentary. Their latest article about the issue was the same "raptor lake mobile is affected as well" article that the everyone and their mom put out yesterday. It's clear that Tom's is copying everyone else because Alderon made the Reddit comment days ago. The article includes this nugget of wisdom.

The biggest issue with Raptor Lake instability is the randomness of the crashes; some chips might only crash in certain conditions while others crash in various other ways.

Very insightful, Tom's, thank you. It's clear that they're just trying to hit a word count.

And if you look at their CPU articles, you'll see 1) a buying guide full of affiliate links, 2) a piece about igor_kavinski's Cinebench scores that he posted here, 3) AMD's ancient 3Dnow instructions are removed from LLVM, 4) another best CPU article full of affiliate links, 5) the raptor lake mobile is affected article.

TLDW: Sending one or 2 CPUs off to a failure analysis lab. It costs 5 figures each. If the oxidation of the vias/fabrication issue is happening, the lab should confirm it. Confirmation was given that yes, the i5 K SKUs for 13th are not immune. 14th gen data hasn't even been provided yet. It is expected to be ugly.
As posted above- a strong do not buy for any 13 or 14 series until further notice from GN.
S.I.s are confirming x53-x55 multi and dog slow DDR speeds like 4800, needed to get the CPUs stable.
One OEM alone, (from the hints I think it is Dell) has up to 8 million CPUs involved, with 6 million or so sus, and between 10-25% of those defective. That is just one OEM.
Some are already ramping up Ryzen SKU as they wait on Intel for guidance.
Intel is definitely in the process of doing a replacement program for the big customers. Unlike my initial guess, this is almost certainly going to blow the Xbox RROD losses away, even in adjusted dollars.
Some of those big customers are furious with the companies that sold them the systems with the CPUs. This is the factor that puts enough pressure on Intel to practically guarantee public statements and actions soon.
If the answer is downclock the CPU significantly and XMP is ignored, you can bet the farm false advertising, as many of us have posited, is going to be real talk. Like us, GN suspects the legal implications are what is holding up the response.

Laying off tens of thousands of employees. Plus this zinger -
announcing pay cuts last month, Intel said it was suspending merit raises, bonuses and cutting its contribution to employees' retirement plans by half.
Not exactly the best motivators for your workers. Might not have anything to do with this , then again...

I watched the video and came away with a totally different take away than GN’s conclusion.

All of his quotes seem to point in the direction that Intel knows what the issue is. They’re telling their partners directly that one of the Intel 7 fabs screwed up and created this premature oxidation issue. This leads me to wonder why not put out a statement identifying the serial numbers effected and issue a recall?

If you're referring to the quote where a partner mentioned the oxidation, I assumed that was because Gamers Nexus mentioned oxidation first.

Let me guess, Paul Alcorn?

That would make me LoL. Twice that I can think of that Dell got bitten in the ass for being basically an outlet for Intel only.

There would certainly be Karma if Dell, which is very strong in US commercial desktop (Intel only) suffered from this more than any other OEM.

They should be benchmarking against the 12900K, because that's the last generation that actually functions correctly.
