AMD Ryzen 7 7840S Lenovo-Exclusive APU Benchmarked
Lenovo's newly released ultra-thin Yoga Air 14s 2023 Ryzen Edition laptop packs an exclusively tuned variant from AMD's 7040 "Phoenix" APU series—we are seeing a whole bunch of these mobile chipsets finally arriving inside portable computer hardware and in handheld games systems (Ryzen Z1 series), following several delays earlier in the year. AMD and Lenovo have partnered up on a special Ryzen 7 7840S eight-core APU, with a custom 30 W TDP profile—likely implemented to synergize with the Yoga Air's thin and lightweight design. Folks in the west have started to enjoy playing around with Ryzen 7 7840HS-equipped laptops, this particular APU has a 45 W TDP rating—also shared by China-market specific 7840H variants.
The MyDrivers review team has been taking Lenovo's Yoga Air 14s 2023 Ryzen Edition for a spin—PC Mark results suggest 10 to 11 hours of normal operation on battery, while lighter office tasking bumps that up to 14 hours. A snazzy 14.5-inch OLED screen with 10-touch support seemed to be a highlighted feature on this fancy slimline laptop. A 5% overall difference in performance (across a number of benchmark suites) was noted by the reviewer—a flagship Ryzen 9 7940HS (45 W) APU narrowly beat its less greedy 30 W sibling. The Yoga Air was judged to offer "top tier" performance that competes with a larger class of notebook (15.6-inch). The reviewer was suitably impressed by Lenovo's chassis design: "To be honest, there are very few thin and light notebooks on the market priced at 8,000 yuan (~$1095) that can surpass Yoga Air 14s 2023 Ryzen Edition in terms of appearance and craftsmanship."
