AMD’s Ryzen 7 5800X3D Draws Less than Half as Much Power than the Intel Core i9-12900KS and Yet Faster in Gaming Workloads

AMD’s Ryzen 7 5800X3D is now available for purchase at retailers across the world. Pairing 64MB of 3D stacked L3 cache (overall 96MB) with the mature Zen 3 CCD results in the fastest gaming processor which beats not only Intel’s Core i9-12900K but the recently launched $749 i9-12900KS as well. Igor (Igor’s Lab) tested the final AM4 chip recently and found it to be an absolute efficiency king.

In gaming workloads at 720p, the Ryzen 7 5800X3D draws just 56W of power when paired with the Radeon RX 6900 XT and a bit more when coupled with the GeForce RTX 3090 Ti. At 1080p with the same GPUs, the average power consumption drops to just 51.6W with the former and 57.4W with the latter. That’s pretty incredible.

In comparison, Intel’s Core i9-12900K draws an average of 130W and 141W at 1080p and 720p, respectively. The higher binner i9-12900KS, on the other hand, consumed 134W and 143W of power at the two resolutions.

This is a rather pathetic showing from Intel’s Core i9-12900K/KS. Despite drawing over 2.5x more power than the Ryzen 7 5800X3D, both chips lose to the sole Zen 3D part across most games.

Overall, this results in an average watt per FPS ratio of 0.2 for the Ryzen 7 5800X3D and a rather embarrassing figure of 0.5-0.6 water per FPS for the Core i9-12900K and 12900KS.
