The AMD Ryzen 9 9955HX3D is an upcoming laptop CPU with 64 MB of L3 3D V-Cache paired with 16 Zen 5 cores that clock at up to a claimed 5.4 GHz. While the 995HX3D hasn't even received an official retail launch date aside from "H1 2025," tech publication Hot Hardware has published some early benchmarks of the new Ryzen 9 CPU, showing off some impressive performance chops that should translate to excellent gaming performance. The test system in question was the MSI Raider A18HX, which pairs the AMD Ryzen 9 9955HX3D with up to 64 GB of RAM and an NVIDIA GeForce RTX 5080 or 5090. According to CPU-Z screenshots taken by Hot Hardware, the 9955HX3D is configured to run at 55 W, although the CPU is capable of up to 75 W TDP. Hot Hardware noted that the 9955HX3D clocked up to 5194.88 MHz on two cores, while one core sat at 5139,98 MHz, and the rest of the cores all sat well below the 2 GHz mark when not loaded.
While Hot Hardware was unable to run direct gaming benchmarks due to release embargoes, the publication did run Cinebench, PCMark 10, and Geekbench, including Geekbench AI. While performance across the board was impressive, with the 9955HX3D scoring a massive 2094 in Cinebench 2024 multicore, which is 20% higher than the next CPU on Hot Hardware's benchmark charts, the AMD Ryzen 9 7945HX from the ASUS ROG Strix Scar 17. Geekbench 6 and UL PCMark 10 tell a somewhat different story, though, with the 9955HX3D scoring slightly behind the AMD Ryzen AI Max+ 395 in both benchmarks. Geekbench 6 was particularly peculiar, since the Ryzen AI Max+ 395 outperformed the 9955HX3D by as much as 48%. The 9955HX3D still beats out all the other chips on the Geekbench 6 test, though, especially in multicore testing, where the next-fastest chip on the chart was the Apple M3 Max. Despite the mixed results when it comes to multicore benchmarks, though, the AMD Ryzen 9 9955HX3D managed to come out on top in every test where single-core performance was directly tested.
