The AMD Ryzen 7 8840HX is a mobile processor with 12 cores, launched in April 2025. It is part of the Ryzen 7 lineup, using the Zen 4 (Dragon Range) architecture with Socket FL1. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 24 threads. Ryzen 7 8840HX has 64 MB of L3 cache and operates at 2.9 GHz by default, but can boost up to 5.1 GHz, depending on the workload. AMD is building the Ryzen 7 8840HX on a 5 nm production process using 13,140 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. You may freely adjust the unlocked multiplier on Ryzen 7 8840HX, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 55 W, the Ryzen 7 8840HX consumes typical power levels for a modern PC. AMD's processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 5200 MT/s. For communication with other components in the machine, Ryzen 7 8840HX uses a PCI-Express Gen 5 connection. This processor features the Radeon 610M integrated graphics solution.
Hardware virtualization is available on the Ryzen 7 8840HX, 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.
