AMD Ryzen 3 4300U vs Intel Core i3-8100B

Last updated:
The AMD Ryzen 3 4300U was introduced as an efficient solution for mobile devices and is based on the Renoir architecture.

Manufactured using the 7-nm process, this processor offers four cores and four threads. The integrated AMD Radeon RX Vega 5 graphics unit enables basic image output, although overall gaming performance remains limited. With a memory bandwidth of 51 GB/s, the data throughput is well-positioned for this class.

The thermal design power is optimized for mobility, resulting in moderate energy consumption. In benchmarks, the AMD Ryzen 3 4300U delivers solid single-core performance. The price-performance ratio is advantageous for entry-level users. This processor is particularly recommended for users looking for a balanced system for everyday tasks and simple multimedia applications where energy efficiency plays an important role.

The Intel Core i3-8100B is a processor from the Coffee Lake S generation designed for compact desktop systems.

It utilizes a 14-nm manufacturing process and features four cores and four threads. The architecture offers a Level 3 cache of 6 MB. In terms of computing power, this model shows advantages in multi-core performance as well as in specific single-core scenarios compared to its AMD competitor. The integrated Intel UHD Graphics 630 handles the graphical display but offers lower performance in graphically demanding scenarios.

With a memory bandwidth of 43 GB/s, the data transfer rate is lower than that of the comparison model. Power consumption is designed for operation in desktop environments. For users who need higher multi-core performance for office applications in small cases, the Intel Core i3-8100B represents a practical choice.
