Methodology
Processors are compared on Cinebench 2024 single-core and multi-core scores from published leaderboard results, alongside core configuration (performance + efficiency cores), base TDP, L3 cache, PassMark CPU Mark, 1080p gaming scores and street pricing where measured. Cinebench reflects rendering-style workloads; gaming performance depends heavily on the GPU and the specific title, so treat single-core standing as directional. Figures reflect the leaderboard snapshot on the page date.
