The ASUS Vivobook S 15 was earlier previewed to be running Qualcomm’s Snapdragon X Elite, but there was little information surrounding its performance. Fortunately, one YouTuber has discovered that whether the Windows 11 notebook is plugged in or running on battery power, the single-core and multi-core results remain nearly unchanged, which is an impressive showing and highlights the noteworthy ‘performance per watt’ attributes of the ARM-based silicon.
The performance comparison was ran by YouTube channel TechTablets, with the host genuinely impressed with how the Snapdragon X Elite performed when running on battery power. In fact, based on the latest data, Qualcomm’s latest and greatest SoC was only 3.17 percent slower in the single-core test when running on battery power and 1.75 percent slower in the multi-core test when away from the wall.
It appears that the unit running in the ASUS Vivobook S 15 is designed to run at full tilt, regardless of whether the Snapdragon X Elite gets its power from the wall or battery. Qualcomm’s partners usually have complete freedom in tweaking the power limits of the SoC based on a particular scenario, so by the looks of these scores, ASUS does not want any performance left on the table. This decision is excellent for those wanting the entire processing headroom for when they are running a taxing workload, such as rendering.
The only drawback to this approach is that the Snapdragon X Elite running at higher power limits will chew through battery life like there is no tomorrow. Additionally, the cell is required to feed the silicon a massive wattage dose each time a stress workload is initiated, which can degrade the battery’s lifespan in the long term.
