The AMD Ryzen Embedded 8840U is a mobile processor with 8 cores, launched in April 2024. It is part of the Ryzen Embedded lineup, using the Zen 4 (Hawk Point) architecture with Socket FP8. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 16 threads. Ryzen Embedded 8840U has 16 MB of L3 cache and operates at 3.3 GHz by default, but can boost up to 5.1 GHz, depending on the workload. AMD is making the Ryzen Embedded 8840U on a 4 nm production node using 25,000 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 Embedded 8840U, which limits its overclocking potential.
With a TDP of 28 W, the Ryzen Embedded 8840U consumes only little energy. AMD's processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 5600 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 Embedded 8840U uses a PCI-Express Gen 4 connection. This processor features the Radeon 780M integrated graphics solution.
Hardware virtualization is available on the Ryzen Embedded 8840U, 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 has added support for the newer AVX2 and AVX-512 instructions, too. This processor is equipped with a Neural Processing Unit (NPU) that comes with a performance rating of up to 16 TOPS.
