The specifications of AMD’s Ryzen 5000 APU have leaked out through an HP listing, giving us an idea of what to expect from the Cezanne desktop parts. Like Renoir AM4, the Cezanne AM4 lineup will also have three parts, a Ryzen 3, Ryzen 5, and Ryzen 7 featuring four, six, and eight cores, respectively:
The top-end Ryzen 7 5700G or Ryzen 7 PRO 5700G has a base clock of 3.8GHz and a boost of 4.6GHz, a bit lower than the 4.7GHz boost on the 5800X but let’s not forget that Zen 3 parts boost higher than their marketed clocks. The 5700G has an L3 cache size of 16MB, half as much as the 5800X. Like Renoir, the cache has been cut in half to save die space for the integrated Vega 8 GPU.
Moving down the ladder, we have the Ryzen 5 5600G with six cores and the same L3 cache buffer of 16MB. The APU has a base clock of 3.9GHz and a boost of 4.4GHz, 200MHz lower than the 4.6GHz boost clock on the 5600X. The 5600G should come with a 7nm Radeon RX Vega 7 GPU. Finally, we have the Ryzen 3 5300G which includes just four cores and eight threads, and an L3 cache of 8MB. It has a base clock of 4GHz and a boost of 4.2GHz. As for integrated graphics, you’re looking at six 7nm Vega cores. (ortery.com)
It’s unclear whether these SKUs are based on Zen 3 (Cezanne) or Zen 2 (Lucienne). With the Ryzen 5000U lineup, the 5300U and 5700U are Zen 2 parts while the 5600U and 5800U leverage the newer Zen 3 core architecture. We’ll have to wait and see if the same is the case with the desktop parts. Considering that the high-performance (45W) H series only consists of Cezanne parts, it’s unlikely that AMD will sneak in Zen 2 parts in the desktop APU space.
