Intel Core i3-9100 vs Intel Core i7-6700K

Last updated:
The Intel Core i7-6700K was released as the flagship of the Skylake S architecture for demanding users.

Manufactured in a 14 nm process, this processor has four cores and eight threads. Thanks to Hyper-Threading technology, it shows higher efficiency in applications that utilize many computing cores. In benchmarks, the performance in multi-core scenarios in certain tests is significantly higher than that of its competitor.

In the gaming sector, the unit benefits from the higher thread count, which ensures more stable frame rates in modern titles. The integrated Intel HD Graphics 530 handles basic graphical tasks. With a thermal design power of 91 watts, the processor requires powerful cooling, but offers high clock speeds in return.

The memory bandwidth of 34 GB/s reliably supports the data flow within the system. The Intel Core i3-9100 belongs to the Coffee Lake S Refresh generation and targets budget-conscious users in the entry-level segment.

Also produced in 14 nm, it offers four physical cores without Hyper-Threading. In single-core performance, it achieves values that compete with the i7 model in some tests, but falls behind in parallel calculations. For simple gaming scenarios, the computing unit is sufficient, but reaches its limits more quickly in CPU-intensive games.

With a TDP of 65 watts, it works more efficiently and generates less waste heat than the comparison model. The integrated Intel UHD Graphics 630 provides a basic solution for image output. The memory bandwidth of 38 GB/s ensures a rapid data exchange. The price-performance ratio is advantageous for simple office applications, while the Intel Core i7-6700K is more recommended for computationally intensive tasks.
