Ryzen 5 7645HX

The Ryzen 5 7645HX is a 6-core / 12-thread processor based on the Dragon Range (Zen4) (2023) architecture, manufactured on a 5 nm process node. It reaches a maximum boost clock of 5 GHz from a base frequency of 4 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 32 MB (total) of L3 cache, plus 1 MB (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 26,097, placing it in the High-End performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,588, while multi-core reaches 11,717. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 13,985.

The Ryzen 5 7645HX fits into the FL1 socket and supports PCIe 5.0 with 28 total PCIe lanes for expansion cards and storage. It supports DDR5-5200 memory at speeds up to DDR5-5200 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 64 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: Radeon 610M — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Ryzen 5 7645HX is primarily designed for Gaming. It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: AMD-V (SVM) — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Core i5-13500HX.

The Ryzen 5 7645HX has a rated TDP (Thermal Design Power) of 45 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately. Recommended cooling: Integrated laptop cooling.

Performance ranking position: #539 out of all indexed processors.
