Performance Compared

Productivity

Intel Core i5-3470T20

Handles basic office applications and web browsing but struggles with heavy multitasking or large datasets.

Intel Core i5-2400SBest25

Handles basic office tasks but struggles with heavy spreadsheets or modern web apps.

Gaming

Intel Core i5-3470T12

The HD 2500 integrated graphics and dual-core design make it completely unsuitable for modern gaming.

Intel Core i5-2400SBest15
