Coffee Lake (rev.B0) (rev.U0)

[Ice Tea]

Asus support is showing two revisions of the latest releases of the Coffee Lake CPU's , Anyone know what this is about?

Intel's U chips are normally low power, so maybe it's that? Can't imagine a stepping jump from B0 to U0, that makes no sense.

Pentium G5400 (3.7GHz, 2C, L3:4M, 54W, rev.B0)
Pentium G5400 (3.7GHz, 2C, L3:4M, 58W, rev.U0)
Pentium G5400T (3.1GHz, 2C, L3:4M, 35W, rev.B0)
Pentium G5400T (3.1GHz, 2C, L3:4M, 35W, rev.U0)

Maybe it's webpage mistakes where they are updating information as i'm sure there was more than that a couple of hours ago.

Definitely two steppings around now:

Thanks Armageus.

Does that mean the B0 stepping is the latest?

* Processors Core i3-8100 and Core i3-8350K with stepping B0 actually belong to "Kaby Lake-S" family

Yes, the Core i3-8350K is just a rebranded i5-7600K.

I guess the difference between the two revisions is the usage of different steppers. Stepping comes from steppers. Revision is the actual version of the printed die.
It starts with A0, with 0, 1, 2 designation can mean which steppers are being used.

My cpu (840) according to CPU-Z has stepping of "4" and revision of "A0"? Can anyone explain to me what are these?
