Blame Apple. They didn't leave enough available capacity for anyone else. And they drove the N3 prices up too!
Nah, this is on AMD. AMD chose to pay for N3E only for Eypc as that’s where the $ is. Qualcomm and MediaTek also get N3E this year. N3E is actually cheaper than N3B.

It could be a very simple oversight due to lack of communication between departments.

Lisa Su (memo to TSMC contact): Ship the review samples ASAP to us!

Shipment arrives and it is addressed to Lisa Su and contents written as "TOP SECRET review samples!". There is only a single "new" guy in the Inbound Logistics department that is supposed to take deliveries from TSMC. Everyone else is out for some important meeting. Wanting to impress Lisa Su, he sends it out to marketing because obviously they will send these samples to publications, right??? Marketing receives these and the single employee there hurriedly sends them out, without noticing that there is no QA inspection stamps on the review sample boxes (everyone is out partying too coz that's what marketing does most of the time).

QA team reads the news that reviewers have samples in hand.

Their head sends memo to Lisa Su: "Seems we were bypassed. Did you give the authorization for that?".

Lisa Su reads the memo and goes: "WTF??? Those morons!" and urgently calls everyone into a meeting where it's decided that the risk of bad publicity is just too high and

Lisa Su orders the recall of the review samples.

The Inbound Logistics Head has a really bad day.
True, never underestimate the most common sense topics when dealing with tech junkies.

Excuses. They could choose some important benchmarks and do a quick "preview". And they could certainly complete all the benchmarking for the comparison/competing CPUs that they have in hand already.
And AMD could skimp on quality control, to release the CPUs 2 weeks sooner, oh wait... And you mean those competing CPUs that are waiting for microcode fixes ?;P

The more I read up about this the more suspicious I become. What we know so far:

1/ Zen 5 is a new uarch, taped out early.
2/ Some reviews samples date way way back.
3/ Amd have already delayed official launch twice.

This screams bugs, bugs and more bugs. I have a feeling now they will do it once more. 3rd's time the charm.

If some of the smaller websites received properly QC'd chips, but the "big boys" didn't, I could see AMD implementing a longer embargo for everyone to get reviews out on the same day, and not p155 off their larger "partners". You could make the argument that reviews over the course of 2 weeks would give them longer in the news, but it doesn't always work like that. Many less people would go to a comprehensive review like Anandtechs (hahaha, I couldn't resist the joke) if 2bitshop released a lesser, but still had graphs, review 2 weeks prior.

It's not as if a lot of these youtube reviews do not wait for legit reviews and create charts that are inline with the legit review numbers without ever testing the CPU's themselves. Then they release their own youtube videos that show almost identical performance numbers.

5.95GHz stock would have been possible with N3E thanks to FinFlex. Sucks that desktop won’t get 3nm anytime soon.
Lots of early batch 7950x3d samples could do 6 ghz boost on ccd1, alas this didn't last for long and at least since march 2023 amd fixed it by replacing good quality cacheless chiplet with something like I have (reboots if fmax is raised above 5.8)

With regards to recall / delay - what might have happened is that AMD noticed some sort of SHA3-like instability that many x3d dual-ccd chips have - they simply crash or reboot in one specific AIDA64 test. Someone might have noticed that while testing CPU for review (or in some sort of pre-review analysis) so they decided to scrap whole batch to ensure this thing does not happen again.

HW Unboxed video has info about AMD's Computex Demo system that had a low performing 9950x ES (early ES), which underperformed even vs 7950X in Cinebech... When they called it out, AMD scrambled and removed the demo systems. That was 8 weeks ago, crazy.

This brings Raja's Vega Frontier launch memories.

What is more hilarious showing of incompetence are those two dates 1 week apart with the flagship being in the later one... Do they really need to take care of the 2*CCD models? Ok, postpone the 1*CCD too to prevent the "Zen 5 slower than 12900K!!!" publicity.

So who wants to be guinea pig and buy a CPU from the first batch now, unless AMD discloses what the actual problem was and how well it could be fixed?
Well, I figure there are two takes one could reasonably have from what AMD said.

1) Launch CPUs should be avoided for risk of getting a defective unit if AMD hasn't fully rectified the issue/QA process to identify it

2) Since AMD recalled all potentially defective CPUs and sent out a wave of "fresh stock" then launch CPUs will be fine, until AMD reevaluates the questionable stock and starts sending those units back out again.

On one hand, take 2 means buying launch day is a good thing. On the other hand, take 1 means it would be prudent to wait it out.

Reviewers need the time to test the cpu, many said it would not be possible to make it in time for 31st if they got CPUs now.
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.

Lmao. Both to the actual issue but also the doomposters everywhere regarding a 2 week delay (lol)
So they push back reviews due to that?? Just instruct reviewers to not show photos of the typo and let them review what they have, then just focus on recalling typo SKUs and shipping corrected ones to vendors-- this didnt have to affect review times whatsoever. And still no official word on pricing. smh.
