The AMD Ryzen 3 5425U is a mobile processor with 4 cores, launched in January 2022. It is part of the Ryzen 3 lineup, using the Zen 3 (Cezanne) architecture with Socket FP6. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 8 threads. Ryzen 3 5425U has 8 MB of L3 cache and operates at 2.7 GHz by default, but can boost up to 4.1 GHz, depending on the workload. AMD is building the Ryzen 3 5425U on a 7 nm production process using 10,700 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. The multiplier is locked on Ryzen 3 5425U, which limits its overclocking capabilities.
With a TDP of 15 W, the Ryzen 3 5425U consumes very little energy. AMD's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 3200 MT/s. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the machine, Ryzen 3 5425U uses a PCI-Express Gen 3 connection. This processor features the Radeon Vega 6 integrated graphics solution.
Hardware virtualization is available on the Ryzen 3 5425U, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
