AMD Ryzen 7 7840U Benchmark, Test and specs

The AMD Ryzen 7 7840U has 8 CPU cores and can calculate 16 threads in parallel. The clock frequency of the AMD Ryzen 7 7840U is 3.3 GHz and turbo frequency for one core is 5.1 GHz. The number of CPU cores greatly affects the speed of the processor and is an important performance indicator.

The AMD Ryzen 7 7840U has integrated graphics, called iGPU for short. Specifically, the AMD Ryzen 7 7840U uses the AMD Radeon 780M Graphics, which has 768 texture shaders and 12 execution units. The iGPU uses the system's main memory as graphics memory and sits on the processor's die.

A photo or video codec that is accelerated in hardware can greatly accelerate the working speed of a processor and extend the battery life of notebooks or smartphones when playing videos.

The processor supports a maximum memory capacity of 256.0 GB distributed across 2 memory channels. It offers a peak memory bandwidth of 89.6 GB/s. Both the type and quantity of memory can have a substantial impact on the overall system performance.

The processor has a thermal design power (TDP) of 28 W watts. TDP indicates the cooling solution needed to effectively manage the processor's heat. It generally provides an approximate indication of the actual power consumption of the CPU itself.

The AMD Ryzen 7 7840U is manufactured using a 4 nm process. A smaller manufacturing process indicates a more contemporary and energy-efficient CPU. In total, this processor boasts a generous 16.0 MB cache. A substantial cache can significantly enhance the processor's performance, particularly in scenarios like gaming.
