News Ryzen 7 Pro 4750G Allegedly Shows Similar Performance As Ryzen 7 3800XT

It wouldn't surprise me at all that 8c16t Zen 2 APUs beat similarly clocked CPUs thanks to the much lower CPU-memory latency of a monolithic design despite having only a fraction as much cache - hiding chiplets' latency penalty is the main reason behind Zen 2's large L3 cache in the first place.
 
Why is this:

The Ryzen 7 3700XT (codenamed Matisse) flexes 32MB of L3 cache, a 3.9 GHz base clock and a 4.7 GHz boost clock.

Even part of the article, when before that sentence was this:

the Ryzen 7 Pro 4750G's performance is in the same ballpark as the Ryzen 7 3800XT that recently came out of AMD's oven.

And after it was this:

The Ryzen 7 Pro 4750G puts up a Processor Arithmetic score of 303.90 GOPS, while the Ryzen 7 3800XT's scores vary between 301.33 and 304.97 GOPS. It might come as a surprise that the results are so close together given that the Ryzen 7 3800XT has a higher boost clock and more thermal headroom in comparison to the Renoir APU. Regardless, there's a possible explanation.

On the Ryzen 7 3800XT, the chiplets interact with each other.................

Seems like references to the 3700xt have no place in the context of this article. Typo?
