Even if they claimed that, it seems highly doubtful based on their results here. There is nothing in the specs that suggests that the gap in performance on a multiplat should be in favor of the PS5, the latest stats have the Series X beating the PS5 in just about every on-paper metric, CPU speed, RAM speed, bus width, pixels per second, texels per second, triangles per second, rays per second. At the very least Series X and PS5 should have near identical performance. The only thing that can explain a performance gap like we're seeing on these launch games is simply bad optimization on Series X, and the best explanation for poor optimization, on games like AC and Dirt 5, which Microsoft had the marketing rights on, is that dev kits and dev tools released too late for developers to optimize properly ahead of release.

Well saying 'nothing' isn't really accurate. PS5 has a higher clock speed for the GPU while SX has more CU's instead. If a game takes full advantage of both, then you'd expect an advantage for SX. But if a game makes use of fewer CU's, then it would be in favor of PS5.
There are some other noteworthy differences between them, like dedicated DMA controller and decompression chip, and the SSD controller is designed to offload large assets like a super fast RAM.
So depending on how games are designed, can't rule out that SX and PS5 may go back and forth on different categories. But I think overall I'd expect SX to generally be ahead by a bit for the most part. The differences shouldn't be as big as we're seeing with Dirt though.

Perhaps they're using the profile of Xbox One or something. Would like to see what it looks like on the old consoles for comparison.

Some fair points, but most game engines can handle more CU's than Series X has, Series X has 52 CU's, all 3 of the newly announced Radeon RX 6000 series GPU's have more CU's than that, with 80 CU's on the flagship 6900 XT, and the early benchmarks for those cards show that games seem to be benefitting from the extra CU's. 

It's certainly possible that things like the SSD controller and decompression chip could lead to better performance on PS5, but you would typically only expect 1st party studios to properly make uses of such things, not 3rd parties, which tend to be somewhat lazy with optimizations. In most cases the obvious on-paper advantages directly translate into better performance on 3rd party multiplats. For a 3rd party multiplat dev to put in the work needed to really take advantage of PS5 to boost games above Series X, it just seems unlikely to me. It just feels more likely to me that the rumors about MS sending out their new Game Core dev tools and dev kits to devs pretty late into the year are true, which would of course lead to devs not having the time to get used to the system before launch. I could be wrong of course.

Either way, we will know within a few months at least. If the delayed tools and dev kit rumors are true, we should see some performance patches for these launch games over the next few weeks that close the gap with PS5, with newly released 3rd parties over the next few months starting to show a smaller gap between PS5 and XSX and an eventual performance lead for XSX as time goes on. If things stay the way they are for the next few months in terms of 3rd party multiplat performance, we'll pretty much know that MS made some kind of bottlenecking design blunder.
