A few benchmarks for a low-power AMD Zen 4 laptop CPU have appeared on Weibo and things are looking good.
AMD’s Zen 4 processors can display remarkable performance-per-watt once they’ve been manually tuned, or if you enable ECO mode in the system setup. You lose some multi-core performance, but the power consumption of the chip drops drastically. That could explain what we’re seeing with some leaked benchmarks for what is purportedly a Ryzen 7 7840U laptop processor.In the main benchmark, Cinebench R23, the leaker on Weibo dropped a single image showing a multi-core score of 14,825 points for the eight-core CPU. By our reckoning, that comes in just behind a Ryzen 5 7600X, and indeed slightly behind the eight-core Zen 3-based Ryzen 7 5800X. While that might not sound impressive, remember that those desktop processors have beefy cooling and 105W or higher power limits.Image: Weibo user 果壳中的空间, by way of HXL (@9550pro on Twitter)
Meanwhile, this mobile processor with its «U» designation should have a power limit of 28W or less.
