Thermals and Power
The Ryzen 7 7800X3D is without a doubt the most energy-efficient gaming CPU on the market. Despite crushing the Core i9-13900K by a massive margin, it sips just 59W on average. At 82C, it runs a little toasty but it’s nothing you’ll have to worry about.
The Core i9-13900K draws over 3x more power (184W) with a thermal peak of 100C. Despite the use of a 360mm AIO cooler, it averaged 88C with a CPU clock of 5.5GHz.
Conclusion
I’ve seen a lot of outlets claim that the Ryzen 7 7800X3D and the Core i9-13900K perform roughly the same. While that may be true for their set of benchmarks, our suite couldn’t disagree more. The 7800X3D bags a clear victory with 8 wins (just 4 for the 13900K) while drawing three times less power and running notably cooler.
