Intel Core i5-8265U vs Intel Core i5-6600

Last updated:
The Intel Core i5-6600 was released in 2015 and is a desktop processor of the Skylake S architecture, developed for classic office computers and gaming systems.

Manufactured in a 14-nanometer process, this processor has four physical cores and four threads, as well as a Level 3 cache of 6 MB. In synthetic measurements, the Intel Core i5-6600 shows higher computing power compared to the mobile model, both in single-core and multi-core loads.

The integrated Intel HD Graphics 530 provides a functional basis for graphic tasks. In gaming scenarios, the Intel Core i5-6600 benefits from a thermal design power of 65 watts, which enables more stable clock rates. With a memory bandwidth of 34 GB/s and PCIe 3.0 support, this processor is aimed at users who prefer a stationary system.

The price-performance ratio is stable for the second-hand market. The Intel Core i5-8265U was released in 2018 and is based on the Whiskey Lake U architecture.

It was primarily designed for use in mobile devices such as notebooks. Despite the 14-nanometer manufacturing process, the focus is on energy efficiency with a thermal design power of 15 watts. It has four cores, eight threads and a Level 3 cache of 6 MB. In multi-core performance, the Intel Core i5-8265U falls behind the desktop model, which is due to the limited energy consumption.

The integrated Intel UHD Graphics 620 is optimized for office applications, but offers little room for demanding games. With a memory bandwidth of 38 GB/s, it offers a good data transfer rate for compact devices. This processor is ideal for users who prioritize mobility, while the pure computing power is lower compared to its stationary counterpart.
