AMD Ryzen 3 7320C vs AMD Ryzen 5 7520C

AMD Ryzen 3 7320C

The AMD Ryzen 3 7320C is a mobile processor for Chromebooks of the Mendocino series. It integrates four older Zen 2 cores (similar to the Ryzen 4000 series like the Ryzen 3 4300U). 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 7520C, the 7320C offers lower clocked CPU cores (400 MHz base, and 200 MHz Turbo).

The 7320C is the Chromebook version of the Ryzen 5 7320U with identical specifications.

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 slightly better than a Ryzen 4000U quad-core thanks to the faster memory and high clock speeds. Therefore, the CPU should be faster than the old Ryzen 3 4300U (4x 2.7 - 3.7 GHz, Zen 2, 7nm).

The Mendocino series are produced in a relatively modern 6nm FinFET process at TSMC and should offer a good power efficiency. The R3 7320C is rated at 15 W TDP and therefore well suited for thin and light laptops.

AMD Ryzen 5 7520C

The AMD Ryzen 5 7520C is a mobile processor for chromebooks of the Mendocino series. It integrates four older Zen 2 cores (similar to the Ryzen 4000 series like the Ryzen 3 4300U). The CPU cores clock from 2.8 GHz (base) to 4.3 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.). The 7520C is the Chromebook variant of the Ryzen 5 7520U and offers the same specifications (and therefore performance).
