Some sleuthing on AppleInsider.com reveals that Apple has, indeed, been meeting with AMD engineers to discuss AMD CPUs. What a prescient article this could be!
From a decade ago? Yeah, I'm sure that's totally a harbinger of things to come any second now.
The base frequency of this chip is 2.4 GHz, and it has a regular 45 W
TDP (sustained power), which can be run in cTDP up mode for 65 W. Two
other plus points on this chip is that it is unlocked, for when an OEM
provides more thermal headroom, and it supports DDR4-2933, which is an
upgrade over the previous generation. Intel's recommended PL2
(turbo power) for the Core i9 is 135 W, and Intel says the recommended
'Tau' is set to 56 seconds for the i9, and 28 seconds for all the other
CPUs. OEMs don't often adhere to these values for notebooks, but they
are provided as a guide.It does mean that in order to hit 5.3 GHz, the
Core i9 is by default allowed to take 135 W across two cores, or 67.5 W
per core. Even at 60W per core, you're looking at 50A of current per
core... in a laptop.
That was almost exactly what I've would have said if I was first to post. Apple would be foolish to market a "pro" laptop with an Intel processor these days.
