AMD "Lucienne" Silicon to Power Certain Ryzen 5000 Series APUs
There's been much chatter in the social media about a new piece of AMD APU silicon, codenamed "Lucienne." 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.

Edit .... T1beriu, you beat me to it
The whole point of going 5000 series with ZEN3 on desktop was to bring the same base architecture to the same nomenclature, as the mobile segment was "lagging" behind.
Fans and the press: AMD finally responded to our complains and decided to name the new CPUs as 5000 series to avoid confusing us!
AMD: hold my beer
edit: Could be that Google ordered them?

2200G/2400G: Zen
2600/2700X/etc. Zen+
3200G/3400G: Zen+
3600/3700X/etc: Zen 2
So maybe:
5200G/5400G: Zen 2
5600/5700X/etc: Zen 3
Examples:
Ryzen 9 6950X = 16-core Vermeer
Ryzen 7 6700X = 8-core Vermeer
RX 6900XT = 80CU Sienna Cichlid
RX 6700XT = 40CU Navy Flounder
RX 6500XT = 24CU Dimgrey Cavefish
Ryzen 9 6900U = 8-core Rembrandt+16-CU RDNA2. (H-model => 24 CUs + Navy Flounder) <== DDR5 DIMMs
Ryzen 7 6700U = 8-core Cezanne+8-CU Vega-H. (H-model => Paired with Dimgrey Cavefish) <== DDR4 DIMMs

Enthusiast:
4000-series/Van Gogh(RDNA2-Navy Flounder),5000-series/Mero(RDNA2-Navi Flounder), 6000-series/Rembrandt(RDNA2-Sienna Cichlid)Mainstream-Performance: 4000-series/Renoir(GCN-Vega), 5000-series/Lucienne(GCN-Vega), 6000-series/Cezanne(CDNA-VegaH)
Products being skipped are strike-through. APU Navi Flounder = One graphics pipe, APU Sienna Cichlid = Two graphics pipes.
