The AMD Ryzen 9 7945HX offers double the primary threads over the Intel i9-14900HX. However, the Intel chipset has eight more cores and double threads, when we combine the power and efficiency cores and threads. It also has a higher turbo boost clock frequency and was launched a year later.

Features	AMD Ryzen 9 7900HX	Intel Core i9-14900HX
Architecture	Zen 4 (Dragon Range)	Raptor Lake
Cores	16	24 (8 performance, 16 efficient)
Threads	32	32 (16 performance, 16 efficient)
Base Clock Speed	2.5 GHz	2.2 GHz
Boost Clock Speed	5.4 GHz	5.8 GHz
Cache	64MB	36MB
Thermal Design Power (TDP)	55 W	45 W
Maximum Turbo Power (MTP)	75 W	55 W

As you can see, the AMD Ryzen 9 7900HX is very different from the Intel i9-14900HX when it comes to the cores, threads, and boost clock speeds. However, they have a very similar power demand as well as similar clock speeds when unlocked.

Both the AMD Ryzen 9 7945HX and the Intel Core i9-14900HX are currently the best CPUs for gaming. Most manufacturers ship laptops featuring these chipsets with high-end Nvidia RTX GPUs. This makes these laptops the best for gaming.

The following framerates have been sourced from YouTube channels like Jarrod's Tech and Digit with machines being powered by the latest Nvidia RTX 40-series graphic cards at Full HD resolution.

Games	AMD Ryzen 9 7945 (Average fps)	Intel Core i9 14900HX (Average fps)
Cyberpunk 2077	110 fps	111 fps
Shadow of the Tomb Raider	226 fps	239 fps
Microsoft Flight Simulator	55 fps	63fps
Red Dead Redemption 2	69 fps	78 fps

As you can see from the table, the extra efficiency cores on the Intel chipset give it a performance boost in most games. Hence, a laptop with the Intel Core i9-14900HX would be the better buy for gaming, especially for users who like to game at Full HD or 2K resolution.
