So the one in your link vs the NUC 11, I assume that is Ryzen 4800U vs Intel i7 1165G7. The 4800U is about 15% slower single core (for short workloads) and about 40-50% faster for multi-threaded workloads. Sustained performance will also be better on the Ryzen as it doesn't throttle as hard or as soon, at least in laptops. I haven't seen any specific NUC testing, so I am assuming it's similar to the laptops those CPUs are in. The 4800U actually trades blows with Intel's much higher wattage flagship 10980HK in anything multi-core.
So for short tasks in something largely single threaded like MS Office, the Intel will be ~15% faster give or take. For anything sustained or multi-threaded, the Ryzen 4800u will be faster and by a much higher margin if multi-threaded. In the Puget Systems Photoshop benchmark, the 1165G7 is a little bit faster than the 4800U as PS is mostly single threaded unless you're using multi-threaded plugins or opening/saving tons of images at once, then the Ryzen would be significantly faster. In Premiere, using a warp stabilizer (2-threads), the 4800U is about 15% faster.
On the GPU side, Intel's Xe iGPUs have caught up to Ryzen's older Vega iGPUs, so that is essentially a wash. They trade blows depending on the specific benchmark.
I'm not able to see exactly that RAM/SSD are in that Asus NUC so I can't comment there.
These guys do a pretty good overview of the 4800U but keep in mind it's comparing against Intel's 10 series rather than 11 series because the 11 series should really be compared with the Ryzen 5000 series:

Too bad the 5000 series is so hard to get, as it handily beats both the above CPUs.
