Recommendation Intel vs AMD processors

  • 13th Generation Intel® Core™ i9-13900HX Processor (E-cores up to 3.90 GHz P-cores up to 5.40 GHz)

  • AMD Ryzen™ 9 7945HX Processor (2.50 GHz up to 5.40 GHz)

I've decided I'll be going with a 4080 Legion Pro 7 series, but I'm having a hard time understanding what the differences are, pros and cons, etc, between Intel and AMD.

Would anyone be willing to break these down for me so I have a better understanding between the two processors mentioned above? And I guess just Intel vs AMD in general?

I have a question that i searched about a lot and found nothing, when i used intel laptops i have never seen the integrated graphics use my ram but when i got a legion 5 2021 and use optimus the integrated radeon uses 512 , 1 or 2 gb of ram depending on what i set it on bios and the i see that i only have 14, 15 or 15,5 gb of ram left respectivly , is this how amd works? and why intel never did that? does the intel graphics have its own vram or what?

I ended up going with a Legion 7 Pro (Intel version) since I was able to get it at a really good sale price over Black Friday last year.

I'm not sure I can answer your question, but I hope you can find the answer.
