The AMD Ryzen 5 PRO 8640HS is a mobile processor with 6 cores, launched in April 2024. It is part of the Ryzen 5 lineup, using the Zen 4 (Hawk Point) architecture with Socket FP7. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 12 threads. Ryzen 5 PRO 8640HS has 16 MB of L3 cache and operates at 3.5 GHz by default, but can boost up to 4.9 GHz, depending on the workload. AMD is building the Ryzen 5 PRO 8640HS on a 4 nm production process 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 5 PRO 8640HS, which limits its overclocking capabilities. With a TDP of 28 W, the Ryzen 5 PRO 8640HS 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, 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 5 PRO 8640HS uses a PCI-Express Gen 4 connection. This processor features the Radeon 760M integrated graphics solution. Hardware virtualization is available on the Ryzen 5 PRO 8640HS, 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.
