AMD Ryzen Z1 Extreme vs Intel Core i7-13700HX

AMD Ryzen Z1 Extreme

The AMD Ryzen Z1 Extreme is a fast high-end laptop processor of the Phoenix series and fastest model of the U-series. It offers 8 cores (octa core) based on the Zen 4 architecture that supports SMT (hyperthreading , 16 threads). The cores clock from 3.3 (base) up to 5.1 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache.

The performance of the R7 7840U is, depending on the workload, only slightly below the Ryzen 7 7840HS (higher base clock speed and TDP). Compared to the previous generation Ryzen 7 PRO 6850U, the 7840U is clearly faster thanks to the Zen 4 architecture and higher clock speeds. Compared to the similar Ryzen 7 7840U, the Z1 Extreme offers no AI engine.

The chip integrates a modern and fasts RDNA 3 graphics card (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 in the modern 4nm process at TSMC. The TDP can be configured between 15 and 30 Watt.

Intel Core i7-13700HX

The Intel Core i7-13700HX is a fast high-end mobile processor of the Raptor Lake series. Is was announced in early 2023 and is based on the desktop Core i7-13700K with combined 16 cores and 24 threads. Eight fast Raptor Cove performance cores (P-cores) with HyperThreading clocking between 2.1 - 5 GHz (4.5 GHz all core boost) and eight Gracemont efficiency cores without HyperThreading (1.5 - 3.7 GHz).

Compared to Alder Lake, Raptor Lake offers improved P-Cores (Raptor Cove micro-architecture) with bigger Caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13980HX, but only 4800 MHz for the i7).

Performance

The average 13700HX in our database is in the same league as the i7-13650HX, as far as multi-thread benchmark scores are concerned, and thus outguns the Ryzen 7 7745HX by a significant margin. This is a very fast chip, as of early 2023.

Thanks to its powerful cooling solution and a long-term CPU power limit of 122 W, the Uniwill GM6PX7X is among the fastest laptops built around the 13700HX that we know of. It can be at least 10% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

The chip's "minimum assured" power consumption sits at 45 W. Its Turbo power consumption is not supposed to exceed 157 W; its Base power consumption is supposed to be around 55 W. Most laptop makers will probably go for a value much higher than 55 W to get better performance.

This Raptor Lake family processor is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
