From the table, it is seen that the odd-numbered SKUs are Lucienne while the even top are Cezanne. The top-end Ryzen 7 5800U is a Zen 3 Cezanne part with 8 cores and 16 threads performing at 2 GHz base and a 4.4 GHz increase. The Ryzen 7 5800U features an 8-CU (512 SP) Vega 8 iGPU clocked at 2 GHz. Comparable to the just recently announced Ryzen 5000 desktop parts, substantial IPC enhancements and reduced latency can be anticipated with the Cezanne SKUs owing to the new shared L3 cache and about 200 MHz much faster clocks.
The Lucienne SKUs are basically Renoir Refreshes now use synchronised multithreading (SMT) along with much faster GPU cores. The Radeon iGPU in both Cezanne and Lucienne SKUs is still GCN-based.
Like the Ryzen 5000 desktop versions, Cezanne can be anticipated to be relatively more expensive than Renoir. It most likely makes good sense to have a Renoir Refresh with SMT allowed and higher clocks to use a cost benefit to OEMs while also making full use of the 7 nm node.
That being stated, there is some possible for confusion for those looking to buy laptops powered by Ryzen 5000, and it is not yet clear how AMD and/or OEMs strategy to inform end-customers about the existence of 2 various architectures in the exact same series.
AMD is anticipated to reveal the Ryzen 5000 APU lineup throughout a virtual CES 2021 event in January.
