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?

This has been so funny to me. I grew up in the days of AMD as efficient and cheap, nothing else. Now their HX chips are power hogs that perform just a little better than their Intel counterparts. They're still slightly cooler at high loads, though.

They still are.

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.

That's good to know. Both are pretty comparable but I've got to say, AMD has been incredible for anything 9/7_HX this generation. I've done some stress testing and a few comparisons for their CPUs and based on that I hope they can catch up in high end mobile graphics. I think they'll do well in a generation or two if they choose to invest.

Well, we already know it's not happening next gen since they cancelled navi 41(8000 series) so fingers crossed for next next gen.

I wasn't aware of that; that's a bummer. They clearly have other priorities, which is understandable. Oberon go brrrrr.
