I read it as the Intel has the AIO. In the x470 review the Wraith was mentioned but I didn't see it mentioned in the x570 review.
Okay, I see in the X470 it says that "we have used the reference heatsink" in the Temperature and Consumption section. While in the X570 article there's a block of text under the Test Equipment that said "Equipment used for this comparison with the Intel Core i9-9900K".
Now we don't know which version of Wraith, but as the R5 2600 and this is a 65W part it probably the Wraith Spire. So as a Core i9-9900K doesn't include a stock cooler we have no idea what Intel would have to actually limit that chip to if they had to box it with some prohibitive lub of aluminium. See if they said this is all the cooler/cost we can stomach to give would they still be able to infer the same performance/clocks/TDP at only about $500? That's what I'm getting at, the Core i9-9900K is great because they can un-hinder it from any base required cooling system. If AMD said this part not held to 65W, say more like the Core i9-9900K and you find you own cooling, what would AMD be able to bin parts at and what would that be able to offer? Sure the way AMD provides the clocks/TDP it's copacetic with the Wraith Spire we believe they will provide. CPU spec's in many respects are tethered to what the cost (and total price point) that a cooling solution can support.
Edit: I have two 2700Xs and they don't start to lose all core boost before start/mid 70 C so if the same is the case here then the stock cooler is sufficient/fair for a review.
Are both running with a completely different Wraith Prism? As that a better and more costly cooler, even demanding tests it will do decently in permitting a 2700X provide it's rated stock configuration.
For a supposed $200 CPU +Cooler to present what is said here is just crazy competitive.
