AMD Ryzen 7 4800H vs Intel Core i3-8100B

Last updated:
The AMD Ryzen 7 4800H is based on the Renoir architecture and uses the 7 nm manufacturing process. This processor is aimed at users of high-performance notebooks who require high computing capacity.

With eight cores and sixteen threads, it offers a strong basis for parallel processes. In relevant benchmarks, the AMD Ryzen 7 4800H is significantly ahead of the comparison model in both single-core and multi-core performance. Thanks to Zen 2 technology and a memory bandwidth of 51 GB/s, data is processed efficiently.

The integrated AMD Radeon RX Vega 7 graphics unit enables smooth display in moderate gaming scenarios. With a Thermal Design Power of 45 watts, the system works efficiently and offers a balanced ratio between energy requirements and computing power for mobile use. The Intel Core i3-8100B comes from the Coffee Lake S family and is produced using the 14 nm process.

It is designed for compact desktop systems and has four cores and four threads. In direct comparison, it is clear that multi-core performance is limited due to the lower number of cores. The Intel Core i3-8100B also achieves lower values than the competing product from AMD in single-core performance.

The Thermal Design Power is specified at 65 watts, while the maximum memory bandwidth is 43 GB/s. The integrated Intel UHD Graphics 630 handles image output, but is primarily intended for office applications and simple graphic tasks. In gaming scenarios, this processor offers fewer reserves. It is primarily suitable for users looking for a solid basic solution for everyday tasks in stationary environments.
