No GB5 processor (averaged in whatever they do it, across the corpus of results) gets close to eve 2100 let alone 2200.
https://browser.geekbench.com/processor-benchmarks

I'm guessing there aren't enough i7-1260P results to get a solid value on that page, but just scanning the list of result,
https://browser.geekbench.com/search?q=i7-1260P,
I find it very unlikely that a reliable "average" value for this chip is 2100, given that most numbers I see seem to be clustered around 1670.
