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.
