Wow, the i7 is better than AMD's i9. AMD went back to the FX ERA. Bravo Intel.

13700K has a lower MSRP and is LGA1700. 7900X has a higher MSRP and doesn't even give that much more performance and its TDP is higher, plus you have to buy an AM5 board. 13700K > 7900X

While tdp is higher, actual power consumption on the 13700k is much, much more. this would mean you could get higher overclocks from a 7900x. it also helps that zen 4 takes a lot lower voltage when overclocking.

im not givin out my name, No, the actual power consumption on the 13700k is much much less than you think. Stock all-core performance can easily be run at 170-180w. You could get higher overclocks from a 13700k within the same stock voltage, let alone higher memory OC. Btw $400 vs $550 lol

This confuses me cause based on benchmarks by different YouTubers, the 13700k total power consumption is worse than the 7900x

Whats it to ya, A lot of tech tubers are anti-Intel TBH. I use both but you can get reasonable TDP from Intel. I have a 13700kf at 5.5ghz all core 4.4ghz on E core. It totally maxed out it uses 270 watts. I have a 11900kf at 5.3ghz full load it uses up to 340watts. 12700k uses just a bit less than the 13th gen.

However AM5 motherboards will be supported, and last longer.
