The AMD Ryzen 4000 APU processors for laptops have already arrived this year, but according to reliable sources, these “Renoir” processors could soon arrive on the desktop with the Zen 2 microarchitecture.
Ryzen 4000 ‘Renoir’ APU models discovered running on a desktop
The current AMD desktop APUs (codenamed Picasso) are still in the Zen+ microarchitecture and 12nm manufacturing process of GlobalFoundries. The transition to Zen 2 and the 7nm process node would bring some significant improvements for the segment.
The unidentified processor core and number of threads are currently unknown, but they are reported to operate within a 35W TDP. Given the TDP classification, it could be an Athlon or one of the efficiency-optimized parts of the GE series of Ryzen 3 or Ryzen 5. For contextual reasons, Ryzen’s existing desktop APUs include up to four cores, while Athlon chips only work with two cores. This suggests that they could be Ryzen 3 4200GE or Ryzen 3 4100GE.
According to the tweet, the CPU has a 3 GHz base clock with a performance between a Ryzen 5 4600U and a Ryzen 7 4700U. The @_rogame source did not share the exact design of the iGPU; however, it seemed to run at a clock rate of 1.2 GHz. The graphics performance was reportedly slower than a Renoir chip with 6 Vega CUs.
It was reported that the AMD Ryzen 4000 desktop APU was tested with a system using an AMD motherboard codenamed “Artic”, which could indicate an unapproved chipset.
The processor was combined with a DDR4-3200 RAM, so there is no doubt that this is a desktop processor. In any case, the APU should be compatible with AMD 300 and 400 series motherboards with a simple firmware upgrade.
