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.
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).
