Description of the processor

The AMD Ryzen 7 7840U is a mobile processor from AMD that has 8 CPU cores. It supports AMDs Simultaneous Multi-Threading Technology and can therefore process up to 18 threads in parallel. This means that the frugal mobile processor is also suitable for more demanding applications, such as graphics or image processing, if you need mobility there.

The 8 CPU cores of the AMD Ryzen 7 7840U are based on AMDs Zen 4 technology (Phoenix). The CPU cores follow a normal core structure with cores of the same size. The clock frequency of the eight cores is 3.3 GHz, in so-called turbo mode up to 5.1 GHz are possible. The use of Turbo mode mainly depends on the heat of the CPU, which in turn depends on the cooling solution of the notebook used.

The AMD Ryzen 7 7840U is AMDs first U-CPU to be equipped with its own AI processing unit (AMD Ryzen AI). This computing unit can significantly speed up certain work processes, e.g. in image processing, and also saves energy.

The AMD Ryzen 7 7840U doesnt have to hide behind the integrated graphics unit either. AMD installs the AMD Radeon 780M graphics here, which is equipped with 12 processing units (768 texture shaders) and can also play modern games in FullHD resolution (1920x768) or below smoothly.

Modern video codecs such as the happy AV1 codec are supported by the graphics of the AMD Ryzen 7 7840U and accelerated in hardware. In addition to a faster rendering speed, this also has an effect on video playback. The battery life of the AMD Ryzen 7 7840U when playing videos is significantly extended thanks to the codec support.

The AMD Ryzen 7 7840U supports up to 256 GB of DDR5-5600 or LPDDR5X-7500 memory. 16 to 32 GB of working memory is currently absolutely sufficient to calculate even more demanding tasks smoothly. The maximum memory bandwidth is 89.6 GB per second.
