AMD Athlon Silver 7120U

The AMD Athlon Silver 7120U is a mobile processor for cheap laptops of the Mendocino series. It integrates two older Zen 2 cores (similar to the Ryzen 4000 series). The CPU cores clock from 2.4 GHz (base) to 3.5 GHz (single core Turbo) and can use 2 MB L3 cache. The Athlon Silver does not support SMT/Hyperthreading and therefore can only work on 2 threads simultaneously. The integrated memory controller only supports fast LPDDR5 memory (5500 MHz max.). Compared to the faster Mendocino models like the Ryzen 5 7520U, the 7120U offers only two cores, no SMT, less L3 cache and reduced clock speeds, leading to a clearly lower CPU performance.

The integrated graphics card (Radeon 610M iGPU) uses the modern RDNA 2 architecture, but only 2 CUs (128 shaders) and clocks with up to 1.9 GHz.

The CPU performance should be to the fastest Ryzen dual-core (Ryzen 3 3250U, 2.6 - 3.5 GHz, Zen 1) but clearly stay behind modern quad-core CPUs (in multi threaded tests).

The Mendocino series are produced in a relatively modern 6nm FinFET process at TSMC and should offer a good power efficiency. The Athlon Silver 7120U is rated at 8-15 W TDP and therefore well suited for thin and light laptops.
