AMD Ryzen 5 7645HX
The AMD Ryzen 5 7645HX is a fast high-end laptop processor of the Dragon Range series. It offers 6 cores based on the Zen 4 architecture that supports hyperthreading (12 threads). The cores clock from 4 (base) up to 5 GHz (single core boost).
The performance of the R5 7645HX should be significantly higher than the fastest 6-core CPU of the Ryzen 6000 mobile series the Ryzen 5 6600H . Especially single threaded performance should be very good thanks to the new Zen 4 cores and relatively high clock speeds. This means even the old Ryzen 9 6980HX (also 5 GHz, but Zen 3) should be slightly slower in single threaded workloads.
The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores, the 7645HX only uses one CCD with 6 of the 8 cores) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU ) in 6nm. The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller.
The R5 7645HX is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP).
