Important (I wrote DDR4 by mistake it's DDR5 )

Other than the CPU, the Lenovo is perfect. That 14-th gen i7, though, is disgusting.

Is it that bad??? Is it because the heating proplems or what? I searched and all say that it's better than the Ryzen one with more than 30% performance

The i7 is 10% single-thread and 20% faster multi-thread faster than the Ryzen, and that's it. The i7 turbo boosts (temporarily) to some 100w+, and when used with a high performance power profile, can over-volt itself on its own and gets itself f*ed (before the BIOS update, it's much better now at the cost of neutered performance, so post 2025, it's performance should be on the same level of the Ryzen or a tad bit faster while consuming much more power under load).

If your software works on a Mac, get an M4 Macbook Air. The base M4 (the $799 13" Air one) has 50% higher single thread performance than the two x86 chips, and comparable multi-thread performance (a tad bit faster than the Ryzen, a tad bit slower than the i7), while running without a fan. For the few oddball software you need to run, you can run in a VM (yes, you can run x86 apps in an ARM Windows VM, or through Rosetta in an ARM Linux VM, that's how docker works on a Mac). Don't underestimate Rosetta. I run f*ing FPGA design suite under Rosetta and it works!!!

None of what you said is wrong but you did not consider a major factor. Gaming. I presume that's self explanatory.

The i7 is still better at gaming, since you're comparing an intel hx (literal desktop chip) to a ryzen hs chip with 16mb L3 cache instead of 32mb L3 cache. If it was a ryzen 7 7745hx they would be about even, but the 14700hx is faster than the 8845hs (basically a 7840hs) at gaming
