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 All of the sudden and without any explanation, the warning has been revoked and Intel continues to supply B1 chips.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.
