Re: “So, i understand you correctly that on MacBook Pro 13inches 2020, Apple put older CPUs then on MacBook Air 2020?”
On the 13” 2020 Intel-based Two Thunderbolt Port MBPs, yes. The 13” 2020 Intel-based Four Thunderbolt Port MBPs got processors from the same generation as the ones in the MacBook Airs.
From MacTracker:
2020 Intel MacBook Air: “Processor: Intel Core i3, i5, or i7 (1000NG4, 1030NG7, 1060NG7) ("Ice Lake")” Processor Speed: 1.1 or 1.2 GHz
2020 Intel 13” Two Thunderbolt Port MBP: “Processor: Intel Core i5 or Core i7 (8257U, 8557U) ("Coffee Lake")” Processor Speed: 1.4 GHz (Core i5) or 1.7 GHz (Core i7)
2020 Intel 13” Four Thunderbolt Port MBP: Processor: Intel Core i5 or Core i7 (1038NG7, 1068NG7) ("Ice Lake") Processor Speed: 2.0 GHz (Core i5) or 2.3 GHz (Core i7)
If I am not mistaken, “Coffee Lake” processors are 8th generation Intel Core processors. “ice Lake” processors are 10th generation Intel processors.
It looks like all of these processors had 4 cores, except for the Core I3 in the cheapest MacBook Airs. It had only 2 cores.
Despite having older-generation CPUs than the Intel-based MacBook Air, your machine turned in somewhat better GeekBench CPU scores. I don’t know how their GPU performances compared. But neither made the cut.
