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.

These parts look identical in TFAs table to the non-"PRO" parts.

Answering my own question, the Anandtech link reveals they're simply mislabeled OEM parts because "marketing genius".
Anyway, I'm sure this basket of apples will make quite the impression.

These are currently targeted at special corporate businesses, not typical consumers. Ryzen PRO CPUs have certain uncommon most modern security features not available in previous common market grade CPUs. Encrypted memory, for one.

Feature like this may debilitate typical hardware DMA attacks via peripheral channels, by gadgetry of agencies.
I consider it a huge step forward.

Get RPi4 or one of its cousins. At peak load 15W works just great for desktop needs. If I need more than cluster is cheap to build and scales easily.

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
alientechnology 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 [wikipedia.org] 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.

Considering a GT 1030 is over 100USD on Amazon today, the 5700G might be a reasonable purchase with the plan to upgrade in a year.
I'm quite confused on pricing. The 5800X is MSRP $449 8C/16T base 3.8GHz, while 5700G is MSRP $350 8C/16T base 3.8GHz. Looking closer the L3 Cache is cut in half to 16MB... I wonder how that will impact the performance of these chips.

They are just guessing the prices, they don't know for sure. But it's entirely possible that the 5700G CPU performance will be almost as good as the 5800X (lower TDP and clocks, but it's a monolithic die instead of chiplets).
The amount of L3 cache a core can access is quadrupled from Renoir. Renoir (except for quad-core 4300U/4450U Pro) has 8 MiB of L3 cache, but it's split into half by the two core complexes (CCXs). The 5700G and most of the Cezanne lineup have 16 MiB of L3 cache and each core can access all of it. Desktop Vermeer: 5800X has 32 MiB shared by 8 cores, 5900X and 5950X have 64 MiB split on two chiplets.
If you were to buy a pre-built desktop with the 5700G (the only way you can buy it for now), you might be hobbled by a low wattage power supply (e.g. ~180 W) not suitable for adding a GPU, and a proprietary power supply that is not feasible or cheap to replace.

Damn,
I want one.. or two . (and likely it will be nearly impossible to find on the market at a decent price due to recent chip shortages.)
The 5700G have similar stats to my 18 month old Ryzen 7 3800X... 8c/16t; 3.8/4.6GHz. Except only 65TDP (compared to my 110TDP) and with an integrated GPU that my 3800x lacks.

If you already have a 3800X and a GPU, you might want to stick with that until the AM5 socket appears. Zen 4 is widely expected to include RDNA2 integrated graphics instead of eschewing graphics:

Zen 4 Ryzen will have DDR5, probably PCIe 5.0 (SSDs are already maxing out PCIe 4.0 x4 [pcgamer.com]), iGPU somewhere (maybe on the I/O chiplet), likely 24 cores maximum (some fear it will max out at 16 cores again, as if that isn't enough). I'm hoping to see gigabytes of DRAM (L4 cache) stacked on the I/O chiplet. Finally, it could have AVX-512 support, maybe only on Epyc.
The reason for adding graphics cores, other than matching Intel's wider availability of integrated graphics, could be to add machine learning acceleration to more products. AMD roadmaps show "CVML" which is likely a reference to "computer vision and machine learning". If "Van Gogh" (~9W TDP mobile) gets announced soon, we could learn more about it then.

Thanks for the info.
And yes, you are correct, I am better off waiting. Between the current shortage and the fact that I have a great gaming machine built around that 3800x (nVidia RTX 2070Super w/8GB VRAM, 64GB System RAM, 1 TB nVme drive) I am likely to wait at least another 18 months to build a new rig, if not 24-30.
These new processors do sound sweet; they do sound drool worthy.
But, I have been building my own PC since college (and those were PC-XT compatibles) I have learned that next years components are always better, and usually cheaper too (though not this year with the chips shortage). So, I will likely wait until one of my games actually take a meaningful performance hit on my machine. I end up making a new gaming rig every 3 years or so.
