AMD Ryzen 3 30 vs AMD Ryzen 3 7320U vs AMD Ryzen 5 40

AMD Ryzen 3 30

The AMD Ryzen 3 30 is a mobile processor for cheap laptops of the Mendocino series that was announced in late 2025. It integrates four older Zen 2 cores (similar to the Ryzen 4000 series like the Ryzen 3 4300U from 2019). The CPU cores clock from 2.4 GHz (base) to 4.1 GHz (single core Turbo) and can use 4 MB L3 cache. Thanks to SMT/Hyperthreading, the CPU can work on 8 threads simultaneously. The integrated memory controller only supports fast LPDDR5 memory (5500 MHz max.). Compared to the fastest Mendocino model the Ryzen 5 7520U, the R3 30 offers lower clocked CPU cores (400 MHz base, and 200 MHz Turbo).

The R3 30 is a rebaded version of the older Ryzen 3 7320U with the same specifications.

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

Performance

We have not tested a single system built around the 7320U, as of September 2023. Expect the chip to be about as fast as the Ryzen 3 3100 (four Zen 2 cores running up to 3.9 GHz).

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your laptop is.

Mendocino series chips are produced on a relatively modern 6nm FinFET process at TSMC and should offer a good power efficiency. The R3 30 is rated at 8-15 W TDP and therefore well suited for thin and light laptops.

AMD Ryzen 3 7320U

AMD Ryzen 5 40

The AMD Ryzen 5 40 is a mobile processor for affordable notebooks based on the Mendocino series. It integrates four older Zen 2 cores (as in the Ryzen 4000 Mobile series) with 2.8 - 4.3 GHz and 4 MB L3 cache. Thanks to SMT/hyperthreading, 8 threads can be processed simultaneously. The integrated memory controller supports dual-channel LPDDR5-5500 MHz. The integrated graphics card uses the current RDNA 2 architecture, but only with 2 CUs (128 shaders) and clocks at up to 1.9 GHz in the 7520U. Technically, the SoC does not differ from the older Ryzen 5 7520U from 2023.

The chip is manufactured in the older 6nm FinFET process at TSMC.
