The full specifications of the AMD Ryzen 5000U series have been revealed.
AMD Ryzen 5000U – a mix of Cezanne and Lucienne
Just a few hours after publishing the story about Ryzen 5 5600U specifications leaked by ExectutableFix, the leaker posted the full specifications of the whole series.
The upcoming mobile low-power processors (~15W, configurable TDP from 10 to 25W) will be a mix of Cezanne and Lucienne processors. These codenames refer to the Zen architecture used, thus the Cezanne is Zen3-based while Lucienne is based on Zen2. This somewhat unusual configuration has been tipped through numerous leaks for the past few weeks. Only now we have the full specifications, thanks to ExecutableFix:
I do love me some teasers. Let's talk business now. Cezanne and Lucienne ?
OPN 100-0000000285
Ryzen 7 5800U (Zen 3 Cezanne)
8 cores / 16 threads
2.0GHz base – 4.4GHz boost
8 CU @ 2.0GHz
16MB L3 cache
10-25W cTDP— ExecutableFix (@ExecuFix) October 18, 2020
According to the data published by ExecutableFix, the processors will see up to a 200 MHz frequency boosts over predecessor (Ryzen 4000 series codenamed Renoir). There is also a change coming to the GPU configuration. AMD is adding more CUs to some parts. For instance, AMD Ryzen 7 5700U which will feature the same GPU configuration as 5800U (8 CUs) along with the same compute core count (8C/16T). The only difference will be the Zen architecture used (Zen3 vs Zen2). Both Cezanne and Lucienne are to use the same GCN-based Radeon Vega graphics.
The ‘flagship’ Ryzen 7 5800U SKU is said to feature 8 cores and 16 threads. This processor will feature 8 GPU Compute Units clocked at 2.0 GHz. The CPU will have 16MB of L3 cache, a double of what Ryzen 4800U and Ryzen 5700U have to offer (both 8C/16T SKUs based on Zen2).
Interestingly, all SKUs in Ryzen 5000U series are to feature SMT, which was not the case for Renoir. The predecessor had three parts with SMT disabled.
According to the leak, AMD is set to launch Cezanne/Lucienne-based AMD Ryzen 5000U series in 2021. We might be hearing more from AMD around ‘Virtual’ CES 2021, possibly with the first laptops deploying in the first quarter.
