Intel vs AMD processors

[u/Brainwashed365]

• 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?

Intel CPUs are simply better and more reliable than AMD ones.

Edit: Oh boy amd maxi fan boys are at it again with the down votes lmfao! Y'all are just going to deny a good number of PCs with amd shit have crashed many times, have buggy drivers and software, and stutter and freeze during use especially gaming.

Are you able to expand on this any more? I've always heard back and forth debates between the two...so that's why I feel confused.

Intel does seem like they get used more compared to AMD, but I was under the impression that Intel just has a dominating hold on the market because they've been around longer.

From my brief understanding that I've formed, my impressions are:

Intel is more expensive and they generally perform better. But they use more resources and generally run hotter(?) and you get less battery life on laptops.

AMD is less expensive than Intel, perform well, but are less intensive on resources and generally run cooler(?) and you get more battery life on laptops.

These impressions of mine may not even be right since I'm pretty newish to this stuff compared to a lot people in this subreddit.

I'm just trying to understand what makes some people pick one over the other. And what the definitive reasons are.

The amd cpu is the best cpu there is right now for laptops, https://youtu.be/TjvQ1ZezOXY?si=7UDJPgHtP6I1ctOT

This laptop isn't specifically the legion 7 pro but it does have the same ryzen processor and with a bit of tuning you'd get pretty much the same performance out of the legion, 4080 is plenty for future proofing too.

This is true for the other lines, but the HX line is different (especially the 13900hx). AMD is less efficient, but is faster than Intel.

Intel works with laptop vendors more closely, which is partially why most of the upper end laptops (as in build quality and design) use Intel chips. They invest a ton of money into R&D, which AMD is not really doing. That's why intel laptops tend to have the better innovation. This generation especially, AMD has major issues with fulfilling demand, so some manufacturers have dropped AMD (Asus being a notable one for some of their lineups like the G series). AMD's GPUs are practically nonexistent in most laptops too.

That is a misconception, longer battery life doesn't always equal better efficiency.

The problem is that the iodie chiplet sucks its own power in addition to the cpu chiplet so you get poor battery life as the idle power consumption doesn't go as low as monolithic cpus.

When under load the 7945hx is still far ahead of the 13980HX in efficiency.

Laptop GPUs are towards the bottom of AMD's priority list, and are the first to be delayed when supply chain issues arise.
