There's been much chatter in the social media about a new piece of AMD APU silicon, codenamed "Lucienne," (possibly after the French singer Lucienne Boyer). It's being rumored that "Lucienne" is a refresh of the current-generation "Renoir" silicon, and is an APU with eight "Zen 2" CPU cores and eight "Vega" NGCUs. One of the first SKUs based on the die is the Ryzen 7 5700U, which surfaced on the AoTS benchmark database.

The 5700U is possibly a 15 W ultra-portable processor, and according to the AoTS benchmark screenshot, it comes with an 8-core/16-thread CPU (the 4700U is 8-core/8-thread). The addition of SMT helps the 5700U shore up much of its performance lead over the 4700U. It also turns out that the Ryzen 5000 will see two APU dies driving AMD's product-stack, with "Lucienne" powering the Ryzen 5 5500U and Ryzen 7 5700U; while the newer "Cezanne" die, which introduces "Zen 3" CPU cores, powers the Ryzen 5 5600U and the Ryzen 7 5800U.
