Choosing Best Laptop

I am looking at buying a laptop and am interested in a "gaming" laptop so that I can utilize some flight simulation program(s).  I am considering either the 1) Dell Alienware x15 R2, or 2) Dell Alienware m15 R7 laptops.  The primary difference is one is . . .

12th Gen, i9-12900H (24 MB cach, 14 cores, 20 threads, up to 5.00 GHz Turbo) and 32 GB of RAM LPDDR5, 5200 MHz integrated, dual channel

and the other is . . . 

12th Gen, i7-12700H (24 MB cach, 14 cores, 20 threads, up to 4.70 GHz Turbo) and 64 GB of RAM 2x32 GB, DDR5, 4800 MHz dual-channel

Is one clearly better than the other for future flight simulation gaming?

Thank-you!
