AMD Ryzen 7 5800U & Ryzen 5 5600U ‘Cezanne’ APUs To Feature Zen 3, Ryzen 7 5700U & Ryzen 5 5500U “Lucienne” To Feature Zen 2 Design
A series of reports from Twitter Fellow, ExecutableFix, have emerged regarding AMD's upcoming Ryzen APU lineup which will feature the Zen 3 based Cezanne & Zen 2 based Lucienne APUs. Both lineups will coexist and branded under the Ryzen 5000 family. The latest information not only gives us new insight into the Ryzen 5000 APU lineup but also strengthens previous reports and rumors.
AMD Ryzen 5000 APU Family To Feature Zen 3 "Cezanne" & Zen 2 "Lucienne" Processors [Update]
Update: Specs for even more Ryzen 5000 APUs have been uncovered by ExecutabeFix alongside two new SKUs, the Zen 3 based Ryzen 3 5400U and the Zen 2 based Ryzen 3 5300U.
While this was already reported, the AMD Ryzen 5000 APU lineup will feature two vastly different line of chips, one will be featuring the Zen 3 architecture while the other will feature an enhanced version of the Zen 2 architecture. The Zen 3 lineup is codenamed Cezanne while the Zen 2 lineup is codenamed Lucienne or Renoir Refresh.
As per the previous and latest reports, the AMD Ryzen 5000 "Cezanne Zen 3" lineup would feature the Ryzen 7 5800U and Ryzen 5 5600U APUs. The Ryzen 7 5800U will feature 8 cores & 16 threads while the Ryzen 5 5600U will feature 6 cores and 12 threads. The AMD Ryzen 5000 "Lucienne Zen 2" lineup would feature the Ryzen 7 5700U and Ryzen 5 5500U APUs. The Ryzen 7 5700U will feature 8 cores and 16 threads while the Ryzen 5 5500U will feature 6 cores and 12 threads.
The performance differences between the lineup would be vastly different. The main reason to split the lineup into Zen 2 and Zen 3 chips is that Zen 3 is apparently going to be slightly more expensive than the Zen 2 parts and also their respective predecessors from the Renoir Ryzen 4000 lineup. The huge 19% IPC improvement and the improved cache and latency design would cover up the price difference but for those looking to get something more mainstream and budget-friendly, the Lucienne Zen 2 APUs will cover that segment.

AMD Ryzen 7 5000U Series APUs:
The top of the stack includes the Zen 3 based Ryzen 7 5800U and the Zen 2 based Ryzen 7 5700U. The Ryzen 7 5800U features 8 cores, 16 threads, and 16 MB of L3 cache with clock speeds set at 2.0 GHz base and 4.4 GHz boost frequencies along with an 8 CU (512 SP) Vega iGPU that's clocked at 2000 MHz. The Ryzen 7 5700U also features 8 cores and 16 threads but with 8 MB of L3 cache and lower clock speeds of 1.80 GHz base and 4.40 GHz boost. The Ryzen 7 5700U features an 8 CU Vega iGPU too but clocks in at 1900 MHz.
AMD Ryzen 5 5000U Series APUs:
As per ExecutableFix, one of 6 core Cezanne APU (most probably the Ryzen 5 5600U) will feature a base clock of 2.30 GHz and a base clock of 4.2 GHz. The chip will also feature an enhanced Vega 7 graphics chip with 7 compute units or 448 stream processors. The GPU will be clocked at 1.8 GHz and the TDP of the chip will be maintained at 10-25W. Compared to the Ryzen 5 4600U (Renoir-U) APU, the Cezanne-U APU comes with a 200 MHz higher base and boost clocks, 1 more compute unit (+64 cores), and a 300 MHz GPU clock speed bump.
The Ryzen 5 5500U features 6 cores and 12 threads based on the Zen 2 core architecture. It has clock speeds rated at 2.10 GHz base and 4.00 GHz boost and carries 8 MB of L3 cache which is lower than the 12 MB L3 cache featured on Cezanne Ryzen 5 part. The iGPU includes a 7 CU (448 SP) Vega chip which is clocked at 1800 MHz.
AMD Ryzen 3 5000U Series APUs:
Finally, there's the Ryzen 3 5400U (Cezanne) and Ryzen 3 5300U (Lucienne) parts which feature 4 cores and 8 threads. The 5400U features 8 MB L3 cache while the 5300U features 4 MB L3 cache. The AMD Ryzen 5 5400U is clocked at 2.60 GHz base and 4.0 GHz boost clocks while the Ryzen 5 5300U is clocked at 2.60 GHz base and a 3.85 GHz boost clock. Both chips feature a 6 CU (384 SP) Vega iGPU with the former clocked at 1600 Mhz and the latter running at 1500 MHz.

All of this including the IPC jump should lead to a vastly better product than the Ryzen 5 4600U but as I mentioned before, at a slightly higher price point which would be justified with the added perf improvement. Benchmarks of the AMD Ryzen 7 5700U "Lucienne" APU were also leaked out during the last month which you can check out over here. The AMD Ryzen 5000 APU lineup is expected to make its first official debut at CES 2021 which is a few months away now so stay tuned as more info comes.
