Any GB5 scores for i7-1280P at around 1800 are just wrong.

The GB5 database is swamped by bad results obtained on misconfigured Windows computers. Now it has become much more difficult to identify the correct results than before, because the database Web site no longer allows anyone to see the complete benchmark results, for example to check the clock frequencies during the tests, but it requires a registered account for that. I will not bother to make an account at them, just to be able to see the complete benchmark results, in order to be able to filter the fake or wrong results.

Nevertheless, there is no doubt that 1800 is wrong, because that is the score that I get on a Zen 3 @ 4.8 GHz (no overclocking, no PBO, slower memory than standard; Zen 3 with standard memory gets around 1810 @ 4.8 GHz and around 1850 @ 4.9 GHz).

i7-1280P is Alder Lake @ 4.8 GHz, which must obtain a ST GB5 score higher than Zen 3 by 15% to 20%, so it should obtain a score around 2100. ST GB5 scales very well with the clock frequency, so an i9-12900HK @ 5.0 GHz must obtain a score not much less than 2200. For desktop Alder Lake there are indeed many results in the database around 2200, which must be the right ones.

That they have compared with i7-1260P is completely certain. Even when looking only at the large titles and not at the small print, the Intel CPU was identified as a "12-core laptop CPU", which matches nothing else but i7-1260P.

The benchmark published by Apple themselves tells precisely that.

It is beyond any reasonable doubt that the Apple benchmark result, obtained by professionals with perfect knowledge about M2, is much more trustworthy than 100 or 1000 GB5 results uploaded by some random dudes, who do not have the slightest idea about what programs are installed on their Windows machines, which run concurrently with the supposedly single-thread GB5 benchmark, decreasing the benchmark score.

It is beyond any reasonable doubt that Apple would have claimed a higher performance than 87% of the speed of Alder Lake @ 4.7 GHz, if that were true.
