I choose intel because I am not doing any task which pushes CPU to it's extreme limits Just want to do regular gaming and streaming and a bit of video editing.

I9 is an old 10nm fabrication process while R9 is 6nm. I9 uses 140-150w during peak while R9 is 40-50w. This means in the normal situation (Your laptop PC won't always use 140-150w on CPU, actually it rarely goes up to 50w), actually in most situations, R9 performs much better than I9. At the same point, I9 is way more expensive than R9. I choose AMD, as always. AND YES! Come on man, I mean Intel should just quit advertising itself, instead, just focus on your chips. Can you just accept TSMC outsourcing? Everyone knows Taiwan TSMC is number 1.

See my comment below, Intel outperforms AMD at 45 W and above, not 100 W. The i9 is more expensive because it is significantly more powerful. In addition, Intel 10 nm has the same transistor density as TSMC 7 nm, which is the main factor in determining power consumption. Intel just boosts up too high on battery which gives them bad battery life, but you can use programs like Throttlestop to stop this and get them much closer in battery life to Ryzen CPUs.

anonymous, Intel/AMD CPUs don't go beyond 45w when the GPU is active (while playing games).

While i9 outperforms r9, it's also viable to mention that i9 tends to draw about 140-150W during peak, while r9 is at 40-50w. Also, median consumption is significantly higher. So consider this to be a mobile processor, id say it's highly significant how much juice it requires to perform like this, regardless of what these paper values show. That results in shorter battery life, or, if restricted consumption, lower performance from i9 than r9. So you should take into consideration whether you'll be using the laptop more on battery or plugged in. Cheers.

There is only one laptop that can even handle 140 W on the CPU (MSI Titan GT77). At 65 W with an i7-12700H, I am still getting a better multi-core score than the Ryzen 9 6900 HX can get at 100W. You can look at the power scaling graphs by Jarrod's Tech - the i7-12700H outperforms the Ryzen 7 6800H at 45W and above - it certainly does not need to go into the 100s. Since both the i9-12900H and Ryzen 9 6900HX are only a fractional step up in clock speed alone from their 7 counterparts but are otherwise identical, the power scaling would be the same here. You can also use the Disable Turbo feature in Throttlestop to significantly increase battery life without a huge drop in performance.

Ryzen can be better if it comes for a lower price, if AMD managed to provide Ryzen for a lower price, it can be favorable by many.
