Spin and bullcrap
I think the problem here is that the word "Core" is actually a marketing term. What is a "Core"? - if someone says "It can process 2 thread simultaneously" then that's a specific, testable claim. But since the term "Core" doesn't have a specific technical meaning, it's a little harder to test the claim since the speaker is allowed to define what a "core" is in terms of the product under discussion.
