The AMD Ryzen Z1 is a mobile processor with 6 cores, launched in May 2023. It is part of the Ryzen Z1 lineup, using the Zen 4 (Phoenix) architecture with Socket FP8. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 12 threads. Ryzen Z1 has 16 MB of L3 cache and operates at 3.2 GHz by default, but can boost up to 4.9 GHz, depending on the workload. AMD is building the Ryzen Z1 on a 4 nm production process, the transistor count is unknown. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. The multiplier is locked on Ryzen Z1, which limits its overclocking capabilities.
With a TDP of 15 W, the Ryzen Z1 consumes very little energy. AMD's processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 5600 MT/s, but with overclocking (and the right memory modules) you can go even higher. 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 Z1 uses a PCI-Express Gen 4 connection. This processor features the Radeon 740M integrated graphics solution.
Hardware virtualization is available on the Ryzen Z1, 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 has added support for the newer AVX2 and AVX-512 instructions, too.
