The AMD Ryzen 9 PRO 8945HS is a server/workstation processor with 8 cores, launched in April 2024. It is part of the Ryzen 9 lineup, using the Zen 4 (Hawk Point) architecture with Socket FP7. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 16 threads. Ryzen 9 PRO 8945HS has 16 MB of L3 cache and operates at 4 GHz by default, but can boost up to 5.2 GHz, depending on the workload. AMD is building the Ryzen 9 PRO 8945HS 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 9 PRO 8945HS, which limits its overclocking capabilities.
With a TDP of 45 W, the Ryzen 9 PRO 8945HS 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 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 9 PRO 8945HS uses a PCI-Express Gen 4 connection. This processor features the Radeon 780M integrated graphics solution.
Hardware virtualization is available on the Ryzen 9 PRO 8945HS, 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.
