Exactly-- but my point is, if it was just a packaging issue, it wouldnt matter if some typo was on the box or the IHS of the review samples. They are saying that not only did they hold off on sending more out, they are recalling all of the ones that were sent out. They would not need to do that if the problem was errors or typos in packaging or IHS.

The box or inscription on the IHS is not what people are referring to when they say packaging issues. In the IC world, packaging means the placing of the die on the substrate and making all of the electrical connections needed.

Many less people would go to a comprehensive review like Anandtechs (hahaha, I couldn't resist the joke)
I don't know why Gavin Bonshor doesn't do some antics on official Youtube channel (if there is one?) to attract more attention to our most illustrious website. He can do so much by donning our official mascot dress (remind me what that is?) and doing some hoopla dancing.

I mean, THIS IS ANANDTECH! *kicks effigy of MLID into the bottomless pit*

Or they forgot to put "," into boosting frequency, so it says it boosts to 57 GHz :-D
They should've left such a typo in. Would've been fun for enthusiasts to chase that elusive speed with all sorts of crazy cooling solutions

57 GHz isn't a lot. If you add up the GHz of all the various on-die structures, maybe the sum of all those exceeds that figure.

They could easily fix a hardware issue within a week or two. Just look at Intel, they didn't need a respin they're able to solve it with a firmware update (at least to the extent of preventing future degradation, they can't undo potential past degradation)

AMD could have looked at Intel's troubles, done some internal reviews "are we vulnerable to the same sorts of problems", found they were, and are making changes to insure voltage levels are kept within bounds to prevent similar issues. By recalling before release they avoid the risk of having chips out there that are operating "unfixed" for months/years by the sort of people who never update their firmware.

Now I have no idea what AMD's problem really is, but the timing of this given Intel's announcement seems a little suspicious to me. A couple week delay to cut the possibility of such issues off at the pass would be well worth it, if it means being able to sit back with a smug grin on your face while Intel deals with the fallout for their problems for the next year or two.

I think the jury is still out on whether Intel is able to fix their issues in microcode or not, but in regards to AMD, I highly doubt this is the case. I did say that it had to be either a QA thing or a microcode/firmware issue. If Intel is telling the truth about their problem, it is a microcode issue and can be fixed in microcode. If it were a microcode issue for AMD, they wouldn't need to recall the CPUs, they could just push the microcode update out through the OS and tell reviewers to be sure they have the latest BIOS/microcode before testing. That would be a lot simpler and cheaper than recalling all of the CPUs that have already shipped and sending out new units.

I also doubt AMD knew about this several weeks ago, as some have said, because in that time frame they have released units to retail. They only recalled them very recently. If they had known about this that long ago, they would never have gotten on store shelves to sell.

No matter the issue, it is much better that AMD is being very proactive and cautious in making sure good working units go out to reviewers and customers. While it kind of sucks that it happened, IMO, they should be judged more on how they handle their mistakes rather than if they make them to begin with, because every company makes mistakes but few handle them well.

"I don't think performance is a concern here" Aussie Steve @ ~8:27 on latest HWUB video.

I listened to that this morning while walking my dog. Steve seems to believe it is a QA thing as well, or at least that is what he gathers from his communication with AMD. One nugget I gleaned was that if he compares his 7900x results to the Italian guy's gaming numbers, the 9900x would be about 18% faster in gaming. Obviously there is a huge caveat there that there is zero control over testing conditions between the two so it's not a reliable figure, but he did say the 7800x3d results between the two match up well, FWIW.

Normally, yes, but when Ian Cutress says "due to a typo" that would be box packaging and labeling, not what you are speaking about.

Is there a chance Strix Halo would outperform 9950X for membw bound workloads?

Does anyone happen to have numbers for theoretical membw for Strix Halo vs 2:1 DDR5 ~8000 on Zen5 DT?

My best guess is that the Yields just aren't there. 5.4 and 5.5GHz kinda works, so the 2 small SKUs can Release on 8th, but the number of 5.6 and 5.7GHz CCDs is so low that it would've been a paper launch.
Going from how omnipresent the 9900X is in marketing and product listing leaks, and the first early review also being on a 9900X, I very much doubt that.

That’s not what hardwareluxx is reporting. It’s also a hardware issue.
They are guessing. They see AMD recalling all units and announcing that they're replacing it with a fresh batch and jump to the conclusion that it must be a hardware issue.

But that's not necessarily the case. The "didn't go through QA" explanation works just as well. It's simply faster to recall and send out the next batch of products, which this time already went through QA. They can then without pressure reopen the recalled units and do the QA for them, which certainly takes more time.
