AMD Ryzen 9 9850HX vs Intel Core i7-14650HX vs AMD Ryzen 9 9955HX3D
AMD Ryzen 9 9850HX
► remove from comparison
The AMD Ryzen 9 9850HX is a high-end notebook processor from the Fire Range series with 12 of 16 cores and hyperthreading (SMT), which means it can process up to 24 threads simultaneously. Unlike the Ryzen 9 9955HX3D, the chip does not offer a 3D V-Cache. The chip was presented at CES in early 2025 and is intended for fast and expensive gaming laptops.
The CPU uses the new Zen 5 architecture for the 12 cores and clocks them at up to 5.2 GHz (single-core boost).
Thanks to the 12 fast Zen 5 cores, the performance should be excellent and well suited for all demanding applications. We assume that the performance will be similar to the old Ryzen 9 7845HX (12 x Zen 4 with up to 5.2 GHz) is similar. The faster Ryzen 9 9955HX and 9955HX3D should be able to set themselves apart significantly due to the higher number of cores (with multi-thread performance).
The 9850HX is intended for large and heavy gaming notebooks and is therefore configurable from 45 - 75 watts TDP (default 55 watts). The SoC is manufactured in the modern 4nm FinFET process at TSMC (both compute dies, I/O die in 6nm) and should therefore have very good energy efficiency.
Intel Core i7-14650HX
► remove from comparison
The Intel Core i7-14650HX is a high-end CPU based on the new Raptor Lake architecture for large and heavy notebooks. The CPU was introduced at the beginning of 2024 and is similar to the older Core i7-13700HX except for slightly higher CPU clock rates (max 200 MHz).
The total of 24 threads are divided into P-cores and E-cores, which we already know from Alder-Lake. The 13700HX offers 8 performance cores (P-cores) with hyperthreading and 8 efficiency cores (E-cores) without hyperthreading. A total of 20 threads are therefore supported. The P-cores clock from 2.2 to 5.2 GHz (single core) or 4.5 GHz (all cores) and the E-cores from 1.6 to 3.7 GHz. The integrated memory controller supports a maximum of DDR5 with 4800 MHz (and not 5600 MHz like the i9 HX models).
Compared to Alder Lake, the new Raptor Lake architecture offers improved P-cores (Raptor Cove architecture with more cache), more E-cores (same Gracemont architecture) and higher clock rates thanks to the improved Intel 7 process. Furthermore, Intel now supports faster DDR5 main memory in the top models (up to 5600 MHz in the i9).
The performance should be slightly above the older Core i7-13700HX (with the same TDP settings and cooling). This makes the CPU ideal for demanding tasks and games.
The 14650HX continues to be manufactured using Intel's improved 10nm FinFET process (Intel 7 process) and is specified with 55 watts of base power and 157 watts of turbo power.
AMD Ryzen 9 9955HX3D
► remove from comparisonThe AMD Ryzen 9 9955HX3D is a high-end notebook processor of the Fire Range series with 16 cores and hyperthreading (SMT), which means it can process up to 32 threads simultaneously. The CPU uses the new Zen 5 architecture for all 16 cores and clocks them at 2.5 to 5.4 GHz (single-core boost). As a special feature, the HX3D has an additional 64M 3D V-Cache on a CCD. This means that the CPU offers combined 128 MB L3 cache and 16 MB L2 cache. The chip was presented at CES in early 2025 and is intended for fast and expensive gaming notebooks.
AMD claims that the Ryzen 9 9955HX3D is the fastest mobile gaming CPU. Based on the experience with its predecessor, the Ryzen 9 7945HX3D, this is quite realistic. The 3D V-Cache in particular can accelerate demanding 3D games. However, the 16 fast Zen 5 cores should also provide enough power for all possible demanding applications.
The 9955HX3D is intended for large and heavy gaming notebooks and can therefore draw quite an amount of power (configurable from 55- to 75 watts TDP, default 55 watts). The SoC consists out of three dies on a package where the processor dies are manufactured in the modern 4nm 4nm FinFET process at TSMC (I/O die in 6nm) and should therefore still have a good energy efficiency.
