AMD has announced "Cezanne" desktop APUs with Zen 3 cores and Vega integrated graphics:

AMD has officially launched its next-generation Ryzen 5000G APUs codenamed Cezanne which features the brand new Zen 3 core architecture. The AMD Ryzen 5000G APUs are aimed at the consumer segment with an initial supply coming to OEM PCs first and later heading out to the gaming & mainstream DIY segment.

The AMD Ryzen 7 5700G will be the flagship offering within the lineup. It will feature 8 cores and 16 threads. The clock speeds are reported at a 3.8 GHz base and a 4.6 GHz boost. The CPU will carry a total of 16 MB L3 and 4 MB L2 cache with the TDP being set at 65W. The APU will also carry a Vega integrated GPU with 8 CUs or 512 stream processors running at clock speeds around 2.0 GHz. The 35W Ryzen 7 5700GE will feature the same specs but reduced core clocks of 3.2 GHz base and 4.6 GHz boost. The CPU should retail at around $350-$400 US.

Unlike the previous-generation "Renoir" desktop APUs, these processors should eventually see a retail release, but will only be offered by OEMs for now.

AMD has also launched OEM-only Ryzen 9 5900 and Ryzen 7 5800 CPUs with lower TDPs and clock speeds than their X counterparts.

    I use an RPi 4 as a desktop. It's overclocked to 2 GHz. Still sluggish when playing a video + doing other stuff (definitely a valid use case considering dual display output is a selling point), opening multiple tabs at once, etc. Graphics performance is low compared to other ARM SoCs. Renoir/Cezanne will run circles around it, obviously at a 65 Watt TDP, but also at the 15 Watt TDP of the 'U' mobile chips (although total system power consumption will be higher). Is it a waste? You are getting pretty good alien technology in a $500 Renoir system that could last for several years. Even a computer 10x more expensive than the Pi4 is cheap.

    Clusters are memes. Using two Pi4 next to each other on separate displays is a possibility. Using scrcpy [] to mirror a powerful Android phone on the Pi is also a good choice.

    RPi 5 is likely to be 4x Cortex-A75 on the same "28nm" node, which should be a straightforward 30-50% improvement that will make the system feel more responsive. Beyond Pi 5, we could use some small Cortex-A55 cores.
