Cinebench R23 single-core shows a 32.6% gap, and Cinebench R15 single-core shows a 100.7% gap. The Intel part's single-core performance is respectable, but the AMD part still leads consistently. For everyday tasks like web browsing, office applications, and light productivity, both processors would feel responsive, though the AMD part holds a measurable edge.

The Intel Core 3 100U has no benchmark wins against the AMD part. However, its data does show competitive single-thread performance relative to its own multi-core results. The 10.3% gap in PassMark single-thread is the smallest margin anywhere in the comparison. This indicates that for lightly threaded workloads, the Intel part is closer to the AMD part than for heavily threaded workloads. The Intel part also has a lower thermal design power (15 watts versus 28 watts), which suggests it could be suitable for fanless or passively cooled designs, though the database does not include thermal or power efficiency benchmarks to confirm this.
