AMD Ryzen 7 7840HS
Benchmarks & Specs

The AMD Ryzen 7 7840HS is an 8-core mobile processor from AMD. The CPU architecture used here is AMDs Phoenix, which combines Zen 4 CPU cores with a fairly powerful RDNA3 iGPU. Both the CPU and GPU performance are very good for a mobile processor. In addition, the AMD Phoenix architecture currently has one of the best energy efficiencies.

The eight equally sized CPU cores support AMDs simultaneous multi-threading technology. This enables two threads to be processed simultaneously per CPU core, which enables the AMD Ryzen 7 7840HS to process a total of 16 threads at the same time. This CPU is therefore also suitable for more computing-intensive applications and computer games.

The clock frequency of the AMD Ryzen 7 7840HS is 3.8 GHz, in Turbo mode the processor can increase the clock frequency to up to 5.1 GHz. For the first time, a dedicated NPU (Neural Processing Unit) for processing AI code is also on board. The XDNA technology, known as AMD Ryzen AI, achieves 10 TOPS in the AMD Ryzen 7 7840HS.

The AMD Ryzen 7 7840HS uses the currently strongest AMD iGPU as integrated graphics. The AMD Radeon 780M has 12 execution units and 768 texture shaders. With a clock frequency of up to 2.7 GHz, up to 4.2 TFLOPS of FP32 computing power is theoretically possible.

The RDNA3 architecture can theoretically process two FP32 commands at the same time, which explains the quite high FP32 performance. In practice, however, applications and games only very rarely manage to fully utilize the graphics card, so the performance in practice is somewhat lower. In 3D Mark TimeSpy, around 3000 points are possible, which is currently enough for the top spot among the iGPUs.

The AMD Ryzen 7 7840HS is manufactured in 4 nm and is very efficient. The processor is very economical, especially in low TDP ranges up to 40 watts, and below 30 watts it is currently the most efficient mobile processor on the market with the Apple M3.
