AMD’s Ryzen 9 7950X is 2x Efficient as the 5950X, Offering the Same Perf at 64W as the 142W 5950X

AMD’s Ryzen 7000 CPUs featuring the Zen 4 core architecture have met with a lukewarm recept from gamers. The exceptional gaming performance of the 5800X3D and the steep asking prices of AM5 boards has resulted in supply outstripping demand. As reported earlier, the sales of the Zen 4 chips dropped sharply in the second week, prompting AMD to cut production in the coming months. Regardless, the Ryzen 7000 processors remain excellent options for those looking to upgrade to next-gen platforms:

Tests conducted by @OneRaichi show that the Ryzen 9 7950X is over twice as efficient as its predecessor across various workloads. In heavily multi-threaded workloads emulated by Cinebench R23 (nT), the 7950X matches the 142W Ryzen 9 7950X at a PPT of only 78W. That’s roughly the same performance at 55% less power.

Moderately intensive benchmarks like Geekbench 5 make the R9 7950X look even more impressive. In this case, the Raphael flagship could catch up to the 142W 5950X with a PPT of just 64W. Here, the Zen 4 part is over twice as efficient as its Zen predecessor, offering the same performance within 45% of the latter’s power envelope.

Looking at these figures, it’s clear that efficiency has remained a strong focus of the latest Ryzen processors. Seeing how the Ryzen 6000 APUs already decimate Intel’s Alder Lake-P offerings in this segment, it’ll be a real treat to see how the Zen 4 mobile family (Phoenix) stacks up to the competition early next year.
