Intel 'degrades' Apollo Lake processor degradation issues - Continues to Supply B1 stepping again

Intel 'degrades' Apollo Lake processor degradation issues - Continues to Supply B1 stepping again

A short while ago Intel issued a warning about Apollo Lake processors having possible degrade issues. That's the B1 stepping of the Apollo Lake processors Celeron N3350, J3355 and J3455 as well as the Pentium N4200. All of the sudden and without any explanation, the warning has been revoked and Intel continues to supply B1 chips.

There is a catch though read it well; customers who do not require IOTG Long Life Product Availability can continue to buy the B1 stepping of the Celeron N3350, J3355 and J3455 and the Pentium N4200. Intel just started reporting this in a revised product change notice. The Internet of Things Group from Intel now delivers the revised F1 stepping to customers who need long-life availability reports Dutch-based website tweakers.

The report differs from the product change notice that Intel published on Tuesday about the F1 stepping of the processors in question. In that document Intel spoke about problems with low pin count, the real-time clock and the SD card interface that caused the signals to degrade faster after several years of use than Intel has as a quality requirement. Intel also stated that the B1 stepping was discontinued and was replaced by the F1 stepping, which can be recognized by the E-suffix in the name of the processor.

Intel does not provide details about withdrawing the earlier product notification. The company does, however, repeat the claim that both the B1 and F1 steppings have been found suitable for PC use.

Intel is literally selling garbage to their customers o_O

Ship me 5 of them for price of one and maybe then I'll be willing to consider them in product since I'll already have spare chips as they do what they are expected to do.

This always annoys me. After this long I should be used to it but I'm not. What is being called a stepping here is most likely NOT really one. It is the process revision. Intel nearly always uses a letter-number combination for the revision. The stepping is nearly always just a number. For example, on the i9 9900X I have the stepping is 4 and the revision M0. Another machine I have is a i7 3820 and it is on stepping 7, revision C2. My laptop is an i7 6700HQ and it is stepping 3, revision R0. These values are reported by CPU-Z. Revision and stepping are two different things. A new stepping usually means a new revision also but a new revision is not necessarily a new stepping. Stepping refers to the set of masks used by the lithography machines or the "steppers". A process revision encompasses all aspects of the fabrication process. There are around a hundred steps to process chips on a wafer and changing any of them constitutes a revision. Masks are rarely revised because it is a very expensive process, costing in the millions, which is why these chips have had so few of them.

Again, refer to CPU-Z. It displays the stepping and revision and you can see that :
1) they are separate values,
2) the stepping is not in letter+number format - that is the revision, and
3) the stepping is just a number.

And nobody talking about this:

Weakness in Intel chips lets researchers steal encrypted SSH keystrokes
Intel Data-Direct I/O makes servers faster. It can also allow rogue servers to covertly steal data.
https://arstechnica.com/information-technology/2019/09/weakness-in-intel-chips-lets-researchers-steal-encrypted-ssh-keystrokes/

Now, researchers are warning that, in certain scenarios, attackers can abuse DDIO to obtain keystrokes and possibly other types of sensitive data that flow through the memory of vulnerable servers. The most serious form of attack can take place in data centers and cloud environments that have both DDIO and remote direct memory access enabled to allow servers to exchange data. A server leased by a malicious hacker could abuse the vulnerability to attack other customers. To prove their point, the researchers devised an attack that allows a server to steal keystrokes typed into the protected SSH (or secure shell session) established between another server and an application server.

Last year I bought the AsRock J355B ITX with the intention of building my own NAS and a pFsense router.
Well, that project somehow never realised fully, because of strange lockups and system freeze out of the blue.
Looks like I won the bad lottery with those boards.
