Where Each One Wins

The Intel Core i5-12400F is the clear winner for multi-threaded and integer-heavy tasks. Its 20.5% lead in Cinebench R23 and 35.6% lead in PassMark integer math make it the go-to for rendering, compiling, and other workloads that scale with cores and threads. Its 26.8% advantage in data compression and 9.2% lead in Geekbench multi-core further solidify its position for general productivity and content creation. This is the processor for a desktop system where performance per watt is less of a concern.

The Intel Core Ultra 5 226V is the winner for single-threaded responsiveness and specific mathematical workloads. Its wins in all single-core benchmarks, including a 9.4% lead in Cinebench R15 and 7.8% in PassMark, mean snappier application performance. The enormous 130.6% lead in find prime numbers and 20.5% lead in physics indicate a strong FPU and specialized instruction handling. Its 8.8% win in data encryption is also notable. For a mobile user who prioritizes battery life (17W TDP) and needs integrated graphics, the Ultra 5 is the superior choice.
