AMD Ryzen 7 PRO 7840HS vs Intel Core i9-14900HX

AMD Ryzen 7 PRO 7840HS

► remove from comparison AMD R7 PRO 7840HS

The AMD Ryzen 7 PRO 7840HS is a fast high-end laptop processor of the Phoenix series. It offers 8 cores (octa core) based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 3.8 (base) up to 5.1 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache.

Compared to the consumer Ryzen 7 7840HS, the PRO models offer additional security, manageability, and reliability features designed for professional users and workstation environments.

The performance of the R7 PRO 7840HS is only slightly below the fastest model, the R9 PRO 7940HS, as the clock speed difference is only minimal (e.g. -100 MHz / 2% slower single core boost). Therefore, the CPU should also perform slightly higher than the old top model Ryzen 9 6980HX (8 Zen 3 cores with up to 4.9 GHz) at 54W TDP and Ryzen 9 6980HS at 35W TDP. Compared to the higher end Dragon Range series, the 7840HS should be similar to the Ryzen 7 7745HX (also 8 Zen 4 cores, max 5.1 GHz, 55W TDP, 32 MB L3).

The chip integrates a modern and fast RDNA 3 graphics adapter (iGPU) called Radeon 780M with 12 CUs and up to 2.7 GHz clock speed. Furthermore, the Phoenix series include a video engine with AV1 de- and encoding, a new Xilinx FPGA based XDNA AI accelerator (Ryzen AI) that should be faster than the AI engine in the Apple M2 SOC and a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC support). The connectivity features includes 2 possible USB 4 (40 Gbps) ports and 20 PCIe 4.0 lanes for a GPU and SSDs.

The Phoenix series uses a single monolithic design (unlike the chiplet design of the 7045HX series) and is manufactured on the modern 4nm process at TSMC. The TDP can be configured between 35 and 45 Watt.

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.
