Methodology
Laptops are compared on Geekbench 6 multi-core scores, processor and graphics hardware, display size and resolution, rated battery life, weight, RAM and storage across launch configurations, and list pricing (USD). Where a model spans several generations, the newest generation is shown. Battery figures are manufacturer or reviewer ratings under mixed use — sustained performance also depends on cooling, which benchmarks only partly capture.
