AMD Ryzen 5 5600X vs AMD Ryzen 9 7940HX
AMD Ryzen 5 5600X
► remove from comparison
The AMD Ryzen 5 5600X is a desktop processor with 6 SMT-enabled (12 threads) and based on the Zen 3 architecture. Launched in November 2020, it is the fastest 6-core Ryzen desktop processor. With a TDP of 65 watts, the Ryzen 5 5600X is the least energy-hungry model in the Zen 3 family to date.
The Ryzen 5 5600X is clocked at 3.7 GHz base clock and can be clocked up to 4.6 GHz with Precision Boost 2.
Performance
The average 5600X in our database is in the same league as the Ryzen 9 4900H and the Ryzen 7 6800HS, as far as multi-thread benchmark scores are concerned. While this isn't the fastest CPU money can buy, it still rips through most workloads with ease, as of mid 2022. Find out more in our full review.
Power consumption
This Ryzen 5 series chip has a default TDP (also known as the long-term power limit) of 65 W to be in line with most desktop processors.
The R5 5600X is built with TSMC's 7 nm process for average, as of early 2023, energy efficiency.
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).
