AMD’s Ryzen 7 6800U is 35% More Efficient than Intel’s Core i5-1260P, On Par with the Apple M1 Pro in Overall Efficiency

AMD’s Ryzen 6000 “Rembrant” processors leverage the two-year-old Zen 3 and an RDNA 2 graphics processor, yet manage to one-up rival Intel’s recently launched Alder Lake-P parts in terms of efficiency. A review of the ASUS Zenbook S 13 from NBC highlights the extent of Team Red’s advantage in this department. The Ryzen 7 6800U powering the notebook was compared to Intel’s Core i7-1260P and Apple’s M1 Pro (8-core).

Testing by NBC reveals that the Ryzen 7 6800U is an impressive 35% more power-efficient than the Intel Core i7-1260P. The former recorded a rating of 374 points per watt in Cinebench R23 (multi-threaded) while the latter was limited to just 244 points in the same. Even Apple’s M1 Pro (8-core) managed 383 points, making it just 2% more efficient than the Ryzen 7 6800U. This is rather remarkable as the M1 leverages TSMC’s more advanced 5nm node while Rembrandt is based on the 6nm process, a refinement of the 7nm node.

In single-threaded workloads, the M1 Pro reigns supreme. It’s over 100% more efficient than the latest Intel and AMD offerings. In CB23 single-threaded, it scores a whopping 219 points per watt. In comparison, the Ryzen 7 6800U and the Core i7-1260P record just 78 and 62 points per watt, respectively.
