I3 vs. I5: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 11, 2024
i3 processors are entry-level, offering basic performance, while i5 processors are mid-range, offering better performance and higher speeds.

Key Differences

i3 processors, designed for basic computing tasks, offer moderate performance and are typically dual-core. i5 processors provide higher performance, suitable for more demanding tasks, and are commonly quad-core.
i3 is ideal for everyday tasks like web browsing and document editing. i5 is better suited for more intensive tasks like gaming and multimedia editing due to its superior speed and processing power.
Generally, i5 processors have a larger cache memory compared to i3 processors, which helps in faster data access and improved performance in multitasking and complex applications.
i3 processors are usually more energy-efficient with lower heat output, making them suitable for small form-factor PCs. i5 processors, being more powerful, can consume more power and generate more heat.
i3 processors are more affordable, catering to budget-conscious consumers. i5 processors are priced higher, targeting users who need more processing power for advanced computing tasks.
