@Arachnotronic, You're again, handling Intel with credit while no other company will have the same credit from you.
14+ / 14++ are both marketing thing by definition as they describe point in time for a manufacturing process.
Any process in the past Intel used got better and better in time.
In the past since real features (CPU Features) cadence was high enough there was no need to define point in time for the process.
In our days there is nothing new to put on the table so Intel, doing right for marketing point of view as it works on you, just said let's market in time process by discrete points in time.
The real question here is has the improvements in the 14++ / 14+ are something beyond anything happened in previous processes?
I'd bet not.
But unless you have inside data (Not marketing data, as the logic of those is explained above) don't just throw Intel Marketing agenda as it was the truth, the whole truth and nothing bu the truth.
