AMD is better as Intel CPU lacks L3 cache and has problems on 13th/14th Gen CPU.

Intel's one is better in almost every aspect in this comparison. More RAM support, 3nm process, more cores, faster RAM, etc. Hate on intel is just forced.

Intel is always good on paper, but in real-life tests it's shit. look at benchmarks in YouTube.

Yea but 96GB is more than enough and the AMD actually performs better in real life and makes the 5090 far more justifiable. The Intel though makes a lot more sense than the amd ai hx 370 in these kind of configurations with powerful GPUs. Not looking great for Intel though if they already need a smaller node, faster ram and more cores to add up to a CPU that still get outperformed by one with slower ram, fewer cores and an older process.

The Intel 285HX has good single core performance, but that does not translate into good gaming at all.

OVO, The AMD 9955HX3D is definitely more powerful than anything from Intel. So is the 9955HX. You need to compare them properly and explain your criteria for defining "better"
