AMD Ryzen 9 7945HX3D vs AMD Ryzen 5 7600X vs AMD Ryzen 9 7940HX

AMD Ryzen 9 7945HX3D

► remove from comparison AMD R9 7945HX3D

The AMD Ryzen 9 7945HX3D 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 2.3 (base) up to 5.4 GHz (single core boost). Compared to the similar R9 7945HX, the 7945HX3D offers an additional 64 MB 3D V-Cache on one CCD-Cluster. This helps in some workloads that can use the additional fast cache (e.g. some games). The guaranteed base clock however was reduced from 2.5 to 2.3 GHz.

The performance of the R9 7945HX3D is similar to the R9 7945HX in workloads that wont make use of the bigger L3 cache. Most games however can use the additional memory. AMD e.g. was advertising the HX3D with 4% to 53% higher performance in 1080p high settings.

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 7945HX3D is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP).

AMD Ryzen 5 7600X

► remove from comparison AMD R5 7600X

The AMD Ryzen 5 7600X is a fast mid-range desktop processor of the Raphael series. It offers 6 cores based on the Zen 4 architecture that supports hyperthreading (12 threads). The cores clock from 4.7 (base) up to 5.7 GHz (single core boost). When all 6 cores are fully loaded, 5.3 GHz is the max. clock speed. 

The performance of the R5 7600X is clearly better than the old Ryzen 5 5600X thanks to the improved architecture and modern 5nm process. The single core performance is very good thanks to the high turbo clock speed (-400 MHz compared to the high end CPUs like the Ryzen 9 7950X). The multi-threaded performance is of course not that competitive due to only 6 cores.

The Raphael 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 Graphics iGPU) in 6nm.

The R5 7600X is rated 105 Watt TDP and Raphael is rather power hungry compared to the 5000 series.

AMD Ryzen 9 7940HX

► remove from comparison AMD R9 7945HX

The AMD Ryzen 9 7940HX is a high-end notebook processor from the Dragon Range series with 16 cores and hyperthreading (SMT), which means it can process up to 32 threads simultaneously. The CPU uses the current Zen 4 architecture for the 16 cores and clocks these from 2.4 GHz (base clock) up to 5.2 GHz (single-core boost). The CPU offers 16 MB L2 cache and 64 MB L3 cache (i.e. a total of 80 MB cache). The 7940HX consists of three chiplets, two CCD clusters with 8 CPU cores each in 5nm (71mm²) and one IO die in 6nm (122mm²) which are all manufactured at TSMC.

The performance of the Ryzen 9 should be comparable to a Core i9-13900HX (24 hybrid cores, max 5.4 GHz) in the top range of mobile processors from 2024. AMD itself advertises a clear lead over the old Ryzen 9 6900HX (8 Zen 3 cores, 4.9 GHz), which can be explained by the additional cores, improved architecture and higher frequencies. Compared to the top model, the Ryzen 9 7945HX, the 7940HX is slightly lower clocked.

The chip also integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB 4), 28 PCIe 5.0 lanes (for GPUs and SSDs), a dual-channel DDR5-5200 memory controller and a small AMD Radeon 610M graphics card (2CUs, 400 - 2200 MHz).

The R9 7940HX is specified with 55 watts TDP and can be configured up to 75 watts (cTDP).
