Intel Core i5-8265U vs Intel Core i3-10300

The Intel Core i5-8265U is a processor of the Whiskey Lake U architecture, primarily developed for mobile devices such as compact notebooks.

In comparison, the Intel Core i3-10300 is a desktop model of the Comet Lake S architecture for home users.

Both models are manufactured using the 14 nm process and feature four cores and eight threads. While the Intel Core i5-8265U has a Level 3 cache of 6 MB, the Intel Core i3-10300 offers a higher capacity with 8 MB. In terms of computing power, the desktop chip is significantly ahead.

In synthetic tests, it outperforms the mobile model in both single-core and multi-core performance by more than ten percent. In gaming scenarios, the Intel Core i3-10300 provides a better foundation due to the Intel UHD Graphics 630 and higher clock speeds. The Intel Core i5-8265U reaches its limits more quickly here, as its thermal design is geared toward energy savings.

While the mobile processor was optimized for low power consumption, the Intel Core i3-10300 requires a stationary power supply and active cooling. The price-performance ratio is advantageous for the Intel Core i3-10300 in stationary systems. However, those who need a lightweight device for on the go should choose the Intel Core i5-8265U.

For more demanding applications and more stable frame rates, the Intel Core i3-10300 is the recommended choice.
