Today AMD is finally lifting the lid on its long-awaited desktop Zen2 based APU family. Using the same silicon as in the Ryzen Mobile 4000 family, AMD is pumping it up into 35 W and 65 models in the same AM4 platform that is in use today. There has been strong demand from PC builders to release these chips, which were on the topics of forum conversation all the way back at CES. There's only one downside to these new processors: you can't buy them on their own. AMD states that the initial release of Ryzen 4000G hardware is for OEMs like Dell and HP only for their pre-built systems.
The new processors use the same 8-core Zen2 plus 8 compute unit Vega that we saw in Ryzen Mobile 4000 at the beginning of the year, but as with previous APU launches, the frequency and power thermals have been pushed up into more manageable desktop environments. To that end, AMD will be launching hardware in the Ryzen 7, Ryzen 5, and Ryzen 3 product lines at both 65 W and 35 W, all on the AM4 platform.
[...] Just to be clear, AMD specified OEM and not system integrators (SIs). On our call, AMD clarified that the market for its APUs is skewed very heavily towards the big mass-market prebuilt customers like HP and Dell, rather than custom home builds. The numbers quoted were around 80% of all APU sales end up in these systems, and by working with OEMs only, AMD can also help manage stock levels of the Renoir silicon coming out of the fabs between desktops and notebooks.
[...] AMD says that they are planning a consumer-grade release of APUs 'soon'. It was stated in our briefing call that there will be a launch of a future Zen2 APU for the consumer market compatible with 500-series motherboards. The company specifically did not say 400-series, but did clarify that the 4000G series announced today was for 400 and 500 series.

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.

AMD's Ryzen 4000 (Renoir) processors may be mobile powerhouses, but for reasons unknown, laptop vendors were reluctant to pair the Zen 2 chips with high-end graphics cards. Ryzen 5000 (Cezanne), on the other hand, appears to have won over manufacturers as there are already retailer postings of upcoming laptops (via Tum_Apisak) with options that span up to a GeForce RTX 3080.
[...] The Ryzen 9 5900HX broke its cover recently, but the Zen 3 chip's secret remains to be unraveled. It's plausible that the Ryzen 9 5900HX is just a faster variant of its H-series counterpart or that AMD may have finally unlocked the multiplier for enthusiasts to overclock the processor, like what Intel allows with its HK-series SKUs.
[...] No one has any idea of when AMD will release Ryzen 5000, but the sudden appearance of benchmark submissions and retailer listings point to an imminent launch. CES 2020 is coming up, and AMD President and CEO Dr. Lisa Su is scheduled to deliver the keynote speech. It would be the ideal venue to announce the mobile Zen 3 chips since the desktop counterparts are already out.
"Cezanne" is the Zen 3 version of AMD's Zen 2 "Renoir" 4000-series APUs. "Lucienne" will consist of Zen 2 APUs (a Renoir refresh) confusingly given the same 5000-series naming as Cezanne.
One of the common theories behind a lack of high-end GPU options has been that AMD's Renoir limits a discrete mobile GPU to a PCIe 3.0 x8 connection (instead of x16), which can be a slight bottleneck for higher end mobile GPUs. Others believe it's just due to OEMs cheaping out on AMD systems.
Upcoming mobile GPUs (like the mobile RTX 3080 mentioned) could bring up to 16 GB of VRAM to laptops.
