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 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.
Performance
The average 7845HX in our database is in the same league as the Core i9-13900HX, as far as multi-thread benchmark scores are concerned. This is a super-fast chip, as of mid 2023; of course, your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.
The R9 7845HX is rated at a TDP of 55 Watt and can be configured from 45 to 75 Watt (cTDP).
The AMD Ryzen 7 7745HX is a fast high-end laptop processor of the Dragon Range series. It offers 8 cores based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 3.6 (base) up to 5.1 GHz (single core boost).
The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores, the 7745HX only uses one CCD) 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.
Performance
The average 7745HX in our database is in the same league as the Core i5-13500HX and the Core i7-13705H, as far as multi-thread benchmark scores are concerned. This is a very fast chip, as of early 2023, and it will make both content creators and gamers happy - for the next two years or so, at least. Your mileage may vary depending on how competent the cooling solution of your system is and how high the CPU power limits are.
The R7 7745HX is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP).
