AMD has positioned itself as the maker of premium notebook processors. The Ryzen 9 7945HX is the fastest mobile processor ever launched. In gaming workloads, it’s 10% faster than Intel’s Core i9-13950HX and more power efficient while packing fewer cores. The Ryzen 7045HX lineup is based on the Ryzen 7000 desktop “Raphael” family, repurposed into BGA notebook parts.
Codenamed Dragon Range, the Ryzen 7045HX series is the first notebook processor lineup to leverage a chiplet architecture. With up to sixteen Zen 4 cores, it offers premium notebook performance with ample battery life, trumping Intel’s hybrid core architecture in every segment.
Compared to its predecessor, the Ryzen 9 6900HX, the Ryzen 9 7945HX is a whopping 78% faster in multi-threaded workloads with an 18% uplift in single-threaded workloads. After losing to Alder Lake-HX for a whole cycle, it also retakes the mobile gaming crown.
Dragon Range notebooks are already out, but you’ll pay a pretty penny to get your hands on one. Even the cheapest Ryzen 9 7945HX notebook (with a GeForce RTX 4070 mobile GPU) costs nearly $2,000, with the RTX 4090 variants going as high as $4,000. You’re better off with a Ryzen 7 7745HX or a Ryzen 5 7645HX alongside an RTX 4070 or a 4080 for optimum gaming grunt. Anything higher up isn’t worth your hard-earned money, as gains will be minimal.
