AMD Ryzen 9 7845HX vs AMD Ryzen 9 7945HX

AMD Ryzen 9 7845HX

► remove from comparison AMD R9 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).

AMD Ryzen 9 7945HX

► remove from comparison AMD R9 7945HX

The AMD Ryzen 9 7945HX is a fast high-end laptop processor of the Dragon Range series. It offers 16 cores based on the Zen 4 architecture that supports hyperthreading (32 threads). The cores clock from 2.5 (base) up to 5.4 GHz (single core boost). The 7945HX is the fastest mobile Ryzen CPU at launch and derived from the desktop Ryzen 9 7950X.

The performance of the R9 7945HX should be similar to a Core i9-13900HX (Raptor Lake, 24 Hybrid cores, 5.4 GHz max) in the high end segment of mobile CPUs for gaming laptops. AMD advertised the R9 7945HX as significantly faster than the old Ryzen 9 6900HX (8 Zen 3 cores, 4.9 GHz max) which makes sense due to the higher core count, clock speed and improved architecture.

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.
