AMD Ryzen Z1 Extreme Proves Very Versatile For Power/Performance - Benchmarks Against The Ryzen 7 7840U
In total I ran more than 260 benchmarks across this range of configurations. Those interested can see all the raw benchmark results and power metrics via this result page.
When taking the geometric mean of all 263 benchmark results, the Z1 Extreme within the ROG Ally when set to the "performance" ACPI Platform Profile managed to deliver 14% better performance than the similarly spec'ed Ryzen 7 7840U tested within the Acer Swift Edge 16 laptop. When running in the default "balanced" profile, the Z1 Extreme was at just 74% the performance of the Ryzen 7 7840U.
While the Ryzen Z1 Extreme in its performance mode was 14% faster than the 7840U, it came with a 65% higher SoC power draw than the 7840U within the Swift Edge 16. The performance mode nearly doubled the average SoC power consumption compared to the default (balanced) mode. In the performance mode, the Ryzen Z1 Extreme saw a recorded peak power consumption at 54 Watts. Meanwhile if wanting to scale down to best power efficiency, the power-saver mode with the Z1 Extreme in the ASUS ROG Ally ran with a 9.8 Watt average and peak of just 17 Watts. The power-saver mode tended to deliver the best performance-per-Watt across the hardware configurations tested for this article.
Anyhow, that's a look at how the Ryzen Z1 Extreme stacks up against the Ryzen 7 7840U laptop SoC. It's quite fascinating to see the CPU performance potential out of this SoC initially for gaming handhelds while it will be interesting to see where else it may find deployments due to its performance capabilities or can also be tailored for delivering very energy efficient use while sporting AVX-512, RDNA3 graphics, and Linux support. It would also be interesting to see how much further the Ryzen 7 7840U could be pushed but at least for the Acer Swift Edge 16 there currently isn't ACPI Platform Profile support under Linux.
