AMD Ryzen 5 7545U

The AMD Ryzen 5 7545U 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 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 R5 7545U is clearly faster than the old Ryzen 5 6600U (Zen 3, 6 cores, 4.5 GHz). Compared to the similar 7640U, the 7545U offers a lower base clock and a slower iGPU. Compared to the similar Ryzen 5 7540U, the 7545U offers a higher clocked GPU and uses the smaller Zen 4c cores for 4 of the 6 CPU cores.

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 new Xilinx FPGA based XDNA AI accelerator (Ryzen AI) is not included in the 7545U.

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 (28 Watt default).
