AMD Ryzen 9 7945HX3D vs Intel Core i9-14900HX vs AMD Ryzen 9 7840HX

AMD Ryzen 9 7945HX3D

► remove from comparison AMD R9 7945HX3D

The AMD Ryzen 9 7945HX3D is a fast high-end laptop processor of the Dragon Range series. It offers 16 cores based on the Zen 4 architecture that supports hyperthreading (32 threads). The cores clock from 2.3 (base) up to 5.4 GHz (single core boost). Compared to the similar R9 7945HX, the 7945HX3D offers an additional 64 MB 3D V-Cache on one CCD-Cluster. This helps in some workloads that can use the additional fast cache (e.g. some games). The guaranteed base clock however was reduced from 2.5 to 2.3 GHz.

The performance of the R9 7945HX3D is similar to the R9 7945HX in workloads that wont make use of the bigger L3 cache. Most games however can use the additional memory. AMD e.g. was advertising the HX3D with 4% to 53% higher performance in 1080p high settings.

The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU) in 6nm. The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller.

The R9 7945HX3D is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP).

Intel Core i9-14900HX

► remove from comparison Intel i9-14900HX

The Intel Core i9-14900HX is a high-end CPU based on the Raptor Lake architecture for large and heavy notebooks. The CPU was introduced at the beginning of 2024 and is a slightly higher clocked variant of the older Core i9-13980HX.

The total of 32 threads are divided into P-cores and E-cores, which we already know from Alder-Lake. Here, 8 performance cores (P-cores) with hyperthreading are used and 16 efficiency cores, so that a total of 32 threads can be processed simultaneously. The P-cores clock from 2.2 GHz (base clock) to 5.8 GHz (single-core turbo) and the E-cores from 1.6 GHz to 4.1 GHz.

Performance

Due to the slightly higher maximum clock rates, the single-core performance of the 14900HX in particular increases slightly compared to the 13980HX. Compared to AMD's top model, the Ryzen 9 7945HX or 7945HX3D the 14900HX comes in just behind (on average in our benchmarks). However, the performance depends on the benchmark and the cooling and is usually very comparable.

Graphics

Like the Intel Core i9-12900HX, the Intel Core i9-14900HX offers an integrated graphics unit. The Intel Iris XE architecture continues to serve as the basis. In terms of performance, however, not much has changed with the Intel UHD Graphics 770.

The 14900HX is manufactured on the improved 10nm FinFET process at Intel (Intel 7 process) and is specified with 55 watts of base power and 157 watts of turbo power.

AMD Ryzen 9 7840HX

► remove from comparison AMD R9 7840HX

The AMD Ryzen 9 7840HX is a high-end notebook processor from the Dragon Range series with 12 cores and hyperthreading (SMT), which means it can process up to 24 threads simultaneously. The CPU uses the current Zen 4 architecture for the 12 cores and clocks these from 2.9 GHz (base clock) up to 5.1 GHz (single-core boost). The CPU offers 12 MB L2 cache and 64 MB L3 cache (i.e. a total of 76 MB cache). The 7840X consists of three chiplets, two CCD clusters with a maximum of 8 CPU cores on 5nm (71mm²) and one IO die on 6nm (122mm²) which are all manufactured by TSMC.

The performance of the Ryzen 9 should be significantly faster than the old Ryzen 9 6980HX (top model Rembrandt H, 8 cores, max 5 GHz). This is achieved by the additional cores, higher clock rate and improved architecture. Compared to the one year older Ryzen 9 7845HX, the 7840HX is clocked 100 MHz lower.

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 7840HX is specified with 55 watts TDP and can be configured from 45 to 75 watts (cTDP).
