The AMD Ryzen 3 5400U is a mobile processor with 4 cores, launched in January 2021. 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 5400U has 8 MB of L3 cache and operates at 2.6 GHz by default, but can boost up to 4 GHz, depending on the workload. AMD is making the Ryzen 3 5400U on a 7 nm production node 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 5400U, which limits its overclocking potential.
With a TDP of 15 W, the Ryzen 3 5400U 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, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer, Ryzen 3 5400U 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 5400U, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
