AMD Ryzen 9 7840HX vs AMD Ryzen 7 7700X vs AMD Ryzen 5 7600X
AMD Ryzen 9 7840HX
► remove from comparison
The AMD Ryzen 9 7840HX is a high-end notebook processor from the Dragon Range series with 12 cores and hyperthreading (SMT), which means it can process up to 24 threads simultaneously. The CPU uses the current Zen 4 architecture for the 12 cores and clocks these from 2.9 GHz (base clock) up to 5.1 GHz (single-core boost). The CPU offers 12 MB L2 cache and 64 MB L3 cache (i.e. a total of 76 MB cache). The 7840X consists of three chiplets, two CCD clusters with a maximum of 8 CPU cores on 5nm (71mm²) and one IO die on 6nm (122mm²) which are all manufactured by TSMC.
The performance of the Ryzen 9 should be significantly faster than the old Ryzen 9 6980HX (top model Rembrandt H, 8 cores, max 5 GHz). This is achieved by the additional cores, higher clock rate and improved architecture. Compared to the one year older Ryzen 9 7845HX, the 7840HX is clocked 100 MHz lower.
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 7840HX is specified with 55 watts TDP and can be configured from 45 to 75 watts (cTDP).
AMD Ryzen 7 7700X
► remove from comparison
The AMD Ryzen 7 7700X is a fast high-end desktop processor of the Raphael series. It offers 8 cores based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 4.5 (base) up to 5.4 GHz (single core boost). Compared to the faster Ryzen 9 CPUs (like the 7900X), the R7 offers less cores and slightly lower clock speeds.
The performance of the R7 7700X is clearly better than the old Ryzen 7 of the 5000 generation thanks to the improved architecture and modern 5nm process. Compared to Intels Alder Lake Core i7-12900K the performance is quite similar but stays behind the newer Rocket Lake i5-13600K (multi-threaded).
The Raphael series still uses a chiplet design with two CCD-clusters (each with 8 possible cores, so only one used for the 7700X) in 5nm and an IO-die (including the memory controller and the Radeon Graphics iGPU) in 6nm.
AMD Ryzen 5 7600X
► remove from comparison
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.
