Built in to a SoC* e.g. a 2060 from 5 years ago had double that in tensor cores it just wasn't part of the SoC. Great improvement for its type/application, dubious marketing claim with the wording.
And it's really not that great even though it's a welcomed improvement - Microsoft is pushing 45 TOPs as the baseline, you just can't get that in an APU yet (well, at least for the next couple months).
Let that sink in.
