AMD Ryzen 5 7535U vs AMD Ryzen 5 8640U: Comparison
What is the difference between Ryzen 5 7535U and Ryzen 5 8640U?
The first real difference is p-core boost clock: Ryzen 5 7535U 4.55 GHz against Ryzen 5 8640U 4.9 GHz. Memory type is not the same on both, DDR5, LPDDR5 on the Ryzen 5 7535U versus DDR5, LPDDR5x on the Ryzen 5 8640U.
Who each one is for
The Ryzen 5 7535U suits ultraportable laptops and business travel, though it is not the pick for gaming laptops and heavy content creation. The Ryzen 5 8640U is the one to take for midrange thin-and-light laptops and office work, browsing and video calls, though it is not built for modern games at high settings without a dedicated GPU and copilot+ PC AI features, which need a 40+ TOPS NPU. It is the wrong buy for heavy video rendering or 3D work, where 8-core chips finish much sooner. Our rating of the Ryzen 5 7535U (7.8/10): the AMD Ryzen 5 7535U is a well-balanced ultraportable chip that prioritizes battery life and everyday responsiveness. Our rating of the Ryzen 5 8640U (7.8/10): the AMD Ryzen 5 8640U is a well-balanced ultraportable chip that prioritizes battery life and everyday responsiveness.
