Since what you seem to really be after is benchmark results. I ran Cinebench R23, the Windows version, using Proton GE in Desktop mode.
I got a multi-core result of 4196, placing the multi-core CPU performance between the Intel Core i7-1165G7 which scored 4904, (1.17x faster than the Deck) and the Intel Core i7-4850HQ which scored 3891 (1.08x slower than the Deck).
I got a single core result of 968, placing the single-core CPU performance between the Intel Xeon W-3265M which scored 1058 (1.09x faster than the Deck) and the AMD Ryzen 7 1700X which scored 959 (1.01x slower than the Deck.) Remember both of these comparisons are single core only. The Xeon is 5.78x faster with the multicore and the Ryzen is 2.12x faster with its multicore.
Keep in mind, the GPU in the Deck will outpace many iGPUs in most laptops, but not a dedicated laptop GPU. And this can be relevant for some high load compute workloads tasks even though it’s not the CPU.
Hopefully that helps.
ReactOS, Haiku, ArcaOS, Icaros Desktop, and the like, I’d imagine.
