AMD Ryzen 9 7940HX vs Intel Core i5-12600K
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).
Intel Core i5-12600K
► remove from comparison
The Intel Core i5-12600K is a mid-range CPU for desktops based on the Alder Lake architecture. It was first announced in November 2021 and offers 6 performance cores and 4 efficiency cores. The performance cores (P-cores) support HyperThreading, leading to 16 Threads that can be processed at once. The performance cores can clock with up to 4.9 GHz, the efficiency cores can clock with up to 3.6 GHz. All cores can use 20 MB Smart Cache. The integrated memory controller supports up to 128 GB DDR5 with 4800 MT/s (dual channel).
Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficiency cores for the best performance.
The integrated graphics adapter is based on the Xe-architecture and called Intel UHD Graphics 770. It clocks between 300 and 1.45 GHz.
For AI tasks, the CPU also integrates GNA 3.0 and DL Boost. Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC and AV1 decode in hardware.
Performance
The average 12600K in our database is way ahead of the Ryzen 9 3900 and the Core i9-10900K, as far as multi-thread benchmark scores are concerned. This is a very fast CPU that should have no trouble running triple-A games for at least a couple of years.
Power consumption
This Core i5 series chip has a Base power consumption of 125 W, with its maximum Intel-recommended Turbo power consumption sitting at 150 W.
The i5-12600K is built with Intel's fourth generation 10 nm process marketed as Intel 7 for lower-than-average, as of mid 2023, energy efficiency.
