The AMD Ryzen 9 5900HX is a mobile processor with 8 cores, launched in January 2021. It is part of the Ryzen 9 lineup, using the Zen 3 (Cezanne) architecture with Socket FP6. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 16 threads. Ryzen 9 5900HX has 16 MB of L3 cache and operates at 3.3 GHz by default, but can boost up to 4.6 GHz, depending on the workload. AMD is building the Ryzen 9 5900HX 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. You may freely adjust the unlocked multiplier on Ryzen 9 5900HX, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 45 W, the Ryzen 9 5900HX consumes typical power levels for a modern PC. AMD's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 4266 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, Ryzen 9 5900HX uses a PCI-Express Gen 3 connection. This processor features the Radeon Vega 8 integrated graphics solution.
Hardware virtualization is available on the Ryzen 9 5900HX, 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.
