The AMD Ryzen 7 5700U is an upper-mid-range processor for mainstream laptop computers. It is a remarkable eight-core chip, since it provides higher-end performance while maintaining low power consumption of 15 Watts. For comparison, typical high-performance processors from AMD’s Ryzen H and Intel Core H series typically consume 45 Watts. The Ryzen 7 5700U is therefore excellent for both regular day-to-day and heavy computing tasks, while preserving battery life and generating relatively low heat.
Nevertheless, the star of the show in the Ryzen 5 5000 U lineup is the Ryzen 7 5800U with even better performance-per-watt, thanks to a newer chip architecture. The 5000 series also features the slower and less expensive six-core Ryzen 5 5500U and quad-core Ryzen 3 5300U.
The Ryzen 5 5500U features an AMD Radeon series integrated graphics processor. It is good only for light gaming, just like the most of integrated graphics processors.
