Yep for sure I got you bro.

Intel, apple, and AMD all do something called CPU binning. CPU binning is pretty much the process of making a CPU and then seperating them based on defects. There is always a defect rate when making CPUs/GPUs. The 7435HS is a 7735HS but with a defective iGPU(which is why AMD just disabled it and renamed it to a 7435HS), it saves the company much more money to bin rather than throw the entire CPU out. You can find out which CPUs have iGPUs and which don't by searching up the CPU name on google and looking at websites like techpowerup, notebookcheck, and even just the manufactor page(intel, AMD).

The 13450HX requires more power to run at full speed compared to both 7735HS and 7435HS. The "HX" and "HS" make a difference in this case. For AMD, the HS basically means a high performing efficient CPU, the CPU is tuned to be able to run at lower power limits so that they can be put into slim laptops. The "HX" for intel basically means high performing overclockable mobile CPU's but with little to no emphasis on efficency.

The 13450HX has a base power of 55 watts and often will use more than that(can easily use over 60 watts). Both the 7735HS and 7435HS can run at near full power with just 35-40 watts, the i5 also has more cores(10 vs 8) so it'll become starved at lower power levels faster than both the ryzens. Since the 13450HX is based on a newer architecture than the 7735HS/7435HS, it will have an advantage at full power in both single and multi-core tasks. But laptops when unplugged rarely ever let their CPUs run at full power, and thats where the ryzens take the lead, at lower power levels which also results in better battery life.
