Benchmark results
The benchmark results for the Raspberry Pi 4 B (Broadcom BCM2711) have been carefully checked by us. We only publish benchmark results that have been created by us or that have been submitted by a visitor and then checked by a team member. All results are based on and fullfill our benchmark guidelines.
Geekbench 5, 64bit (Single-Core)
Geekbench 5 is a cross plattform benchmark that heavily uses the systems memory. A fast memory will push the result a lot. The single-core test only uses one CPU core, the amount of cores or hyperthreading ability doesn't count.

Description of the processor
The Broadcom BCM2711 is soldered on the Raspberry Pi 4 B mainboard and has 4 CPU cores. The clock frequency is itself for ARM processors at low 1.5 GHz. By configuration file, the processor on the Raspberry Pi 4 B can be overclocked, with good cooling usually 1.7 - 1.8 GHz are possible. The CPU cores are based on the Cortex A72 design, the command set is ARMV8-A64 (64 bit).As an internal graphic, the SOC brings a Broadcom VideoCore VI with which has 4 execution units and 64 shaders. This is not suitable for games or other more demanding tasks, but should only take over the image or video output of the Raspberry Pi.
The Broadcom BCM2711 SOC is manufactured in an older 28 nm manufacturing and can therefore only be operated with relatively low clock frequencies before the SOC is heavily heated. Modern video codecs as well as H.265 / HEVC can decode the Raspberry Pi 4 b by hardware and usually play reasonably fluid. Therefore, it is also suitable with restrictions as a media player, at least when the 1080p resolution is sufficient. 4K contents can also be played in part also liquid, but this does not apply to all 4K content.
The Raspberry Pi 4 B can be purchased at 1.2.4 or 8 GB LPDDR4-2400 memory, with only one memory channel being used. The memory bandwidth is accordingly not very high. The Broadcom BCM2711 comes with a TDP of 7.5 watts, but can also be operated with less energy (and then with less power). The SOC has a 1 MB Level 2 cache.
For a price from current from 35 euros (1 GB version) to 75 euros (8 GB version), the Raspberry Pi 4 B is a good entry-level solution and a significant upgrade to the predecessor model. Smaller network solutions Like a small NAS, e.g. Ideal with the Raspberry Pi 4 B can be realized.
