AMD’s 8 Core Ryzen 9 6900HS Consistently Beats Intel’s 14 Core i7-12700H at a TDP of 45W: Destroys Alder Lake in Efficiency

AMD’s Ryzen 9 6900HS turned out to be a surprise contender to Intel’s higher-end Alder Lake-P processors, most notably the Core i7-12700H. In addition to being highly competitive in content creation and gaming workloads, the Rembrandt chips are incredibly power-efficient. AMD’s Zen 3 core was the most efficient x86 core, to begin with, but when paired with TSMC’s N6 node, it utterly destroys the Core i7-12700H and its Alder Lake brethren.

Looking at the benchmarks from ComputerBase, you can see that the Ryzen 9 6900HS (an 8-core CPU) manages to easily outperform the 14-core i7-12700H when the TDP of both the chips is set to 45W. In Cinebench R20, the former scores 4,873 points, beating the latter by roughly 100 points. In CB R23, the Alder Lake part fares a bit better but still fails to establish a meaningful lead.

The same can be witnessed in Blender, another heavily threaded rendering application. At 45W, the Ryzen 9 6900HS finishes well ahead of the Core i7-12700H. The former takes 1,029 seconds to finish the render, beating the latter by 124 seconds. Remarkably, even with the boost (PL2) power set to 60W, the 14-core Alder Lake-P SKU fails to catch up with the Rembrandt flagship.

All this makes you wonder about the impact of the efficiency cores on the Intel Alder Lake mobile SKUs. Not only are these chips slower than AMD’s Ryzen 6000 offerings at 45W and below, but they also happen to be far less power efficient.
