> Both AMD and Intel are competing for bragging rights, but they are both pushing the power envelope to accomplish it. Yes and no. AMD just released the 5800X3D which is just a teensy bit slower than Intel's top-dog...but it uses a bit more than one third the power the I9-12900KS and 13900K do. Right now you can get a blisteringly-fast (for gaming and other certain specific workloads) AMD CPU with power consumption a skooch over 100W. It yields a nearly 25% increase in framerate on some games, which is huge, and does it at less power usage than the non-stacked-cache variant: https://youtu.be/hBFNoKUHjcg?t=515 https://youtu.be/hBFNoKUHjcg?t=515 You're right about the next generation of Ryzen processors using more power, but nobody knows how much, partly because AMD using some silly nonsense to calculate "TDP", and review units aren't out yet: https://youtu.be/hVnJbiYOCq4?t=363 https://youtu.be/hVnJbiYOCq4?t=363

The Ryzen 7 5800X3D was released in early April 2022. It's rated for a 105W TDP, and draws up to about 190-195W depending on workload[0]. In 1080p gaming (useful for exaggerating the CPU bottleneck), the 13900K outperforms the 5800X3D by about 11%[1]. Review units of "next generation of Ryzen processors" have been out since late September when they became available to buy, so you can read reviews and find out their actual power usage[2]. The Ryzen 9 7950X is shown to push system power consumption up to 355W while running Blender. (TechSpot reviews linked simply because they include power consumption in their reviews.)

  if youre buying a 13900 for 1080p gaming youre throwing away money anyways. ltt includes the 5800x3d in their numbers for comparisons at resolutions people buying super high end cpus actully want to drive. At idle, where the cpu spends most of it's time, the Intel chips are winning significantly.

    >At idle, where the cpu spends most of it's time, the Intel chips are winning significantly. Well, by 3W for an entire system. Which isn't worth worrying about in my opinion. So personally, I'd be looking at other specs to help me decide between them. https://www.guru3d.com/articles_pages/intel_core_i9_13900k_review,6.html https://www.guru3d.com/articles_pages/intel_core_i9_13900k_r...

I put a 5800X3D in my gaming PC. It actually runs kind of hot and draws more power than I expected from the reviews, especially at idle. For day to day use (including non-gaming work) my old Intel CPU consumes less power overall because the idle power was so much lower. Peak TDP isn’t everything.
