Intel Core i3-8350K vs Intel Core Ultra 7 366H

Last updated:
The Intel Core i3-8350K was released as part of the Coffee Lake S generation for desktop systems, while the Intel Core Ultra 7 366H was developed on the Panther Lake H architecture for modern notebooks.

In manufacturing, the Intel Core i3-8350K uses the 14 nm process and offers four physical cores as well as support for PCIe 3.0. In contrast, the Intel Core Ultra 7 366H is based on advanced 2 nm technology. When comparing computing power in benchmarks, the Intel Core Ultra 7 366H massively outperforms the Intel Core i3-8350K in both single-core and multi-core performance.

This trend continues in gaming scenarios, as the Intel Xe3 4 Core Graphics 32 EUs (Panther Lake) offers far higher graphical performance than the Intel UHD Graphics 630 integrated into the desktop model. Regarding power consumption, the Intel Core i3-8350K has a thermal design power of 91 watts, which requires solid cooling.

The Intel Core Ultra 7 366H, on the other hand, is tuned for efficiency, leading to optimized heat dissipation despite high performance. With a memory bandwidth of 136 GB/s, the mobile model is significantly better equipped for data-intensive applications than the desktop processor with 38 GB/s.

The price-performance ratio of the Intel Core i3-8350K is rather low compared to newer generations, while the Intel Core Ultra 7 366H represents the more modern choice. The Intel Core i3-8350K is recommended for simple office computers, the Intel Core Ultra 7 366H for powerful mobile workstations and demanding multimedia.
