That's an interesting spin on the data and a peculiar way to ignore the sentiment explicitly stated by the author. That mode, the high performance one you're quoting, is going to run at 1080p or 1440p on the vast majority of consumer television sets. From Digital Foundry:
"This is great for seeing top-end performance metrics, but it's bad news for the experience - especially on PlayStation 5. This is because 120Hz output is locked to any screen that supports 120Hz, no matter the resolution. So consider a highly popular 4K screen - the LG OLED B8. PS5 sees that it is 120Hz-compatible, and overrides 4K resolution. All modes will run at a 120Hz refresh rate, at 1080p resolution - which is absolutely not ideal. Another popular screen is the Samsung NU8000. It's a 4K screen but on PS5, Devil May Cry will force through the 120Hz refresh rate instead, resulting in a downscale to 1440p that the user has no control over.
And this is where Xbox Series X has an advantage that's crucial. Users can simply dip into the video settings, select 60Hz and Devil May Cry 5 runs in a generally stable way - a locked 60 frames per second is very much preferable to the fully unlocked set-up on a 120Hz screen whether you're gaming on PS5 or Xbox Series X. We have shared our findings with Capcom a while back, and fingers crossed there'll be a solution to the issue, but the tl;dr version is simple enough on paper: allow PS5 users to select between 60Hz and 120Hz output resolution.
So a more accurate way to interpret that review would be, assuming 4k is the yardstick we're measuring next-gen titles by, is the Series X has an advantage at 4k with the vast majority of existing consumer Television sets. With the performance mode, it's not clear to anyone at this point that these gaps in performance won't disappear with future patches:
"It's conjecture on our part, but there is the sense that there's a graphics API bottleneck here that impacts performance on the Xbox side in some scenarios, while PS5 simply powers on."
