Comparison of the two processors

This comparison focuses on two mobile processors, both of which were released by their respective manufacturers in the second quarter of 2021. The Intel Core i7-11800H is still manufactured with a structure width of 10 nanometers, whereas the AMD Ryzen 9 5900HX is already manufactured using the smaller 7 nanometer process.

Both processors have 8 physical cores and support Hyperthreading technology, which means that they each have 16 threads (logical cores) at their disposal. The Intel Core i7-11800H has a base clock frequency of 2.30 gigahertz and a maximum turbo clock of 4.60 gigahertz. The AMD Ryzen 9 5900HX has a significantly higher base clock frequency of 3.30 gigahertz, but the maximum turbo clock is identical at 4.60 gigahertz.

In our benchmarks, the processors are sometimes on par and sometimes one or the other is a bit faster. From this we conclude that the processors have approximately the same performance.

The Intel UHD Graphics of the eleventh generation with 32 EUs (Execution Units) is used as the internal graphics unit in the Intel Core i7-11800H. This iGPU clocks at up to 1.45 Gigahertz, has 256 shader units and achieves an FP32 computing power of 742 GigaFLOPS with single precision. The AMD Radeon 8 Graphics (Renoir) is integrated in the AMD Ryzen 9 5900HX. This graphics unit clocks at 1.90 gigahertz and has 8 execution units and 512 shader units. The iGPU, manufactured using the 7-nanometer process, achieves 1946 GigaFLOPS, which is almost three times the graphics performance of the Intel graphics unit.

The Intel Core i7-11800H has 2 memory channels and thus supports the use of up to 128 gigabytes of DDR4-3200 RAM. The AMD Ryzen 9 5900HX also has 2 memory channels, but can only be operated with a maximum of 64 gigabytes of RAM. In addition to the DDR4-3200 modules that are also supported, the AMD processor also supports the LPDDR4-4266 main memory type.
