AMD Ryzen 7 7700 vs AMD Ryzen 9 7940HX
AMD Ryzen 7 7700
► remove from comparison
The AMD Ryzen 7 7700 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 3.8 (base) up to 5.3 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 7700 is slightly below the higher clocked AMD R7 7700X (that also features a higher TDP).
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 Ryzen 7 7700 is rated at a TDP of only 65 Watt and therefore suited for smaller desktops (and cooling solutions).
AMD Ryzen 9 7940HX
► remove from comparison
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 made with a 5nm node (71mm²) and one IO die on 6nm (122mm²), are all manufactured at TSMC's fabs.
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).
