AMD Ryzen 9 7845HX
The AMD Ryzen 9 7845HX is a fast high-end laptop processor of the Dragon Range series. It offers 12 of the 16 cores based on the Zen 4 architecture that supports hyperthreading (24 threads). The cores clock from 3 (base) up to 5.2 GHz (single core boost). The 7845HX is the second-fastest mobile Ryzen CPU at launch and derived from the desktop Ryzen 9 7900X.
The performance of the R9 7845HX is significantly faster than the old top model Ryzen 9 6980HX (8 Zen 3 cores, 5 GHz max) thanks to the higher core count, improved architecture and higher clock speed.
The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible 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 R9 7845HX is rated at a TDP of 55 Watt and can be configured from 45 to 75 Watt (cTDP).
