AMD Ryzen Z1

AMD Z1

The AMD Ryzen Z1 is a fast mid-range laptop processor of the Phoenix series. It offers 6 cores (hexa core) based on the Zen 4 architecture that supports SMT (hyperthreading, 12 threads). The cores clock from 3.2 (base) up to 4.9 GHz (single core boost). The processor includes 6 MB L2 cache and 16 MB L3 cache.

Thanks to the new Zen 4 architecture and higher clock speeds, the Ryzen Z1 is clearly faster than the old Ryzen 5 6600U (Zen 3, 6 cores, 4.5 GHz). Compared to the similar Ryzen 5 7540U, the Z1 offers a higher boost clock, lower (optional TDP) and no AI accelerator.

The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 740M with 4 of the 12 CUs and 2.5 GHz clock speed. Furthermore, the Phoenix series include a video engine with AV1 de- and encoding 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 35 and 45 Watt.
