I just read the whole statement (previously I also commented negatively because the question was about A370M and I just focused on the "up to 2X part" of the statement)
I'll try to paint a positive picture of this:
Since the statement is in plural, it probably refers to Arc A370M/A350M/Iris Xe Max A200M products that will be launched at the same time, hence the "up to 2X" part. So essentially the message could just be 2X for A370M and less than 2X for the rest. Also I saw some fps results in Notebookcheck regarding AMD 680M and the performance is probably around -10% of what AMD's release performance slides are suggesting. Also 1280P IGP should be around 10% faster on average than Vega 8 (5900HS). If you really (I mean really) stretch it, you could end with A370M performance being 35% faster vs 680M 6800U 2.2GHz iteration. So regarding A380 you are back at -5-10% vs 1650 Super. So essentially we're back at the original performance assumptions, so I guess we just have to wait for some valid comparisons then.
