Possible AMD Ryzen PRO 4000G Series SEP Prices Surface, Incompatible with 400-series Chipset
AMD's recent announcement of its Ryzen 4000G and Ryzen PRO 4000G series desktop processors lacked a key detail - pricing, possibly because it's irrelevant to end users as the processors are sold only in the OEM channel. momomo_us secured a slide (possibly by AMD's channel marketing), which puts out SEP (suggestive) pricing per chip in n-unit tray quantities. Apparently, the Ryzen 7 PRO 4750G, and its energy-efficient -GE variant, are priced at USD $309. The Ryzen 5 PRO 4650G/GE comes with a $209 price, and the Ryzen 3 PRO 4350G/GE at $149.
Prices of the other parts in this slide appear to be stuck at their respective launch-time SEP pricing, since all of the price-cuts AMD implemented appear to be unofficial, and specific to retailers and regions. AMD also updated its familiar-looking processor-to-chipset compatibility slide with the inclusion of the new 4000G series. Apparently the new processors only work with AMD 500-series chipsets, such as the B550, X570, and the commercial-segment exclusive PRO565 chipset. This is strange since "Renoir" is now confirmed to lack PCIe gen 4.0, and only spares gen 3.0 x8 for PEG, which means 400-series chipsets are excluded due to ROM size limitations to squeeze in AGESA microcode supporting several generations of processors and microarchitectures. Interestingly, AMD assured customers of Ryzen 4000-series compatibility with 400-series chipsets. Perhaps they were only referring to the "Zen 3" based "Vermeer" processors, as the slide shows.

Since i have X570 with the latest (stable) BIOS that specificly states support for new CPU's with Radeon Vega Graphics it should work.
IMHO, if they were decent human beings, Zen+ should have been Zen 2 and so on to match their CPU prefix number naming which would have made Zen 3 = Ryzen 3000 CPU's, BUT NO! The mobile variants just released (Zen 2 I believe) would be Ryzen 3000 series instead of the 4000 series? This whole naming scheme is making me dizzy and sick.
The only confusing part will be the APU which is always 1 generation slower in terms of architecture, but yet having the same model number as the newer CPUs (no iGPU). I feel AMD made the decision to give it this confusing naming convention because if they name it as Ryzen 7 3700G (instead of Ryzen 7 4700G), it would seem like an older model. It is partially correct to say that it is based on an older CPU architecture, but I cannot deny that it is a new product because it is not 100% the same as the chiplet design on the older Ryzen 3xxx series.
If the new APU's can save me $250AUD not buying GPU for office/audio/image/stream/etc/noGames then it still sounds good to me. Based on previous experience, it's going to be a long wait (ie. about 12 months) before the Zen3 based APU's arrive to the desktop.
This is what an OEM would want.
Also, pushing these chips on OEMs, they can claim to offer 4000 series CPUs with brand new chipsets. Which is exactly what they want. And if the DIY market have no 4000 series, the more the bait for them.
if i give my customers "usb stick" flash posibility, like on boot hold clear cmos while on one specific port is an usb fat32 drive with ./update/bios.bin
Then i could do a specific bios file for every 'series' of cpu and have enought space for the rest modules, or support strange models by cutting features.. No Software Raid with CPU XYZ model..
but no sell the customer new boards ;-(
