Just a few hours ago we wrote about the AMD Ryzen 5 APU specification 5600 U that appeared on the web. I am talking about 6-core and 12 – a threaded APU processor for laptops, based on Zen 3 cores and integrated Vega graphics chip. Now we come back to the topic, because the same source also presented the specification of the other APU processors from the Ryzen series 5000-AT. Some of these units belong to the Lucienne-U series which is just a streamlined version of the Renoir. In turn, some of the processors in question are new designs based on the Zen 3 architecture. However, all the upcoming APUs have a common denominator, which are graphics systems based on the Vega architecture.

all AMD Ryzen APUs are specified 5000 – U – some of them belong to the Lucienne series , others for Cezanne.

AMD Ryzen 5 5600 U – Cezanne APU specification

AMD is working on a total of six APU Ryzen processors 5000 – U – three of them will use Zen cores 2 (Lucienne-U), three more will be based on the Zen 3 (Cezanne-U) architecture. We expect Cezanne-H processors to have a similar block configuration, but with correspondingly increased core clocks and higher TDP. The processors to be allocated to the Lucienne-U series are: AMD Ryzen 3 5300 U, AMD Ryzen 5 5500 U and AMD Ryzen 7 5700AT. AMD Ryzen 5 5400 U, AMD Ryzen 5 5600 U and AMD Ryzen 7 5800 U are Cezanne-U circuits based on the newer and improved Zen 3 cores.

As you can see, AMD has completely ditched units with no support for multithreading in its upcoming series of low-voltage processors. All upcoming units will support SMT, thus offering even higher efficiency. So far, laptop manufacturers have used APU much more often, i.e. Ryzen 5 4500 U or Ryzen 7 4700 U that did not use SMT. Particular series of processors also received Vega graphics chips with more CU blocks. The exception is the Ryzen 7 5800 U, which still has the Vega 8 graphics chip, but with the highest clock 2000 MHz (the current Vega 8 has a clock 1750 MHz). Ryzen 3 processors will get Vega 6 instead of Vega 5, Ryzen 5 processors will get Vega 7 instead of Vega 6. Ryzen 5 5700 U will also receive iGPU Vega 8 (instead of Vega 7), but with a slightly lower clock reaching the maximum 1900 MHz. Looking at the clocks in Turbo mode, we can expect that AMD Ryzen 5 processors will receive similar values ​​5600 H and Ryzen 7 5800 H, 4.2 GHz and 4.4 GHz respectively. The manufacturer will certainly introduce the top Ryzen 9 units with even higher clock speeds. In addition, we know from the leak that the top AMD Ryzen 7 5800 U will receive twice as much L3 cache – 16 MB instead of 8 MB. Smaller units will also get more L3 caches. The premiere of APU Lucienne and Cezanne is expected in January. Perhaps then we will also know the details of the third series of Van Gogh (Athlon 4000).

I do love me some teasers. Let’s talk business now. Cezanne and Lucienne
