This is just comical.
You guys do realize why AMD felt compelled to report the originally higher number, right?
They made such a big deal at GloFo that their decision to go gate-first was superior to Intel's because it was going to give them superior scaling and superior transistor density.
That didn't happen, clearly. And now that the honeymoon between AMD and GloFo is over, with AMD cancelling their 28nm brazos shrink, AMD now no longer feels compelled to be the PR mouthpiece that is/was vouching for GloFo's previous technology claims.
The reality is the xtor density did not drastically improve, they made a performance trade-off to go gate-first in hopes of nailing a cost benefit in yields and die-size and they failed on both accounts.
It is funny still though that even the 1.2B number is BS as pointed out above, it falls short when accounting for the stuff we know to be there (L3$) without accounting for the other stuff we know is present (IMC, IO, etc).
AMD, please stop the facepalm train, just cry uncle and stop making fools of yourselves
