AMD Ryzen 5 PRO 7640U vs AMD Ryzen 5 7545U
AMD Ryzen 5 PRO 7640U
► remove from comparisonThe AMD Ryzen 5 PRO 7640U 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 3.5 (base) up to 4.9 GHz (single core boost). The processor includes 6 MB L2 cache and 16 MB L3 cache.
Compared to the consumer Ryzen 5 7640U, the PRO models offer additional security, manageability, and reliability features designed for professional users and workstation environments.
Thanks to the new Zen 4 architecture and higher clock speeds, the R5 PRO 7640U is clearly faster than the old Ryzen 5 6600U (Zen 3, 6 cores, 4.5 GHz). Compared to the similar 7640HS, the U-series offers a lower TDP and slightly lower core clocks.
The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 760M with 8 of the 12 CUs and 2.6 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 35 and 45 Watt.
