What a waste, 1GB lan. Why does Asus, Gigabyte and Asrock keep missing the mark on these.
Edit: On closer inspection, there appears to be unpopulated pads for a PHY and a gbic module. So its product segmented, and this is the one without. Wonder if the other one would be OEM only.

There are preliminarily two other models listed on their website:
B650D4U-2T - 2x broadcom 10gb rj45
B650D4U-2L2T/BCM - 2x broadcom 10gb rj45 in addition to the 2x 1gb, but this one is listed as built to order so I'd guess OEM only on that one.
I'm not sure how much of these will end up making it to market as they've had several Intel W680 based boards listed for months and only one is available now.

It's for pro use, it exist in many "flavor" due to what OS will be used on it (as an exemple intel 10Gb and 2,5Gb have compatibility issue with some OS and program on pro side).
A bit like when you have ASPeed graphic instead of using IGP/APU that are more powerfull, pro search compatibility 1st.
Also when you buy many board at once (mean a lot) and your infrastructure is 1Gb max, the price compared to upper version can be a sale argument.

It depend on the use, for some even the B650 is too "powerfull" for their need, but they need a pro quality standard with less expensive and/or economic chipset than the W680.
It's for this reason that you have even lower version than this one, with everything that a pro need (24/7 use, many lan, PCIe X8, U2, SAS/SATA controler build in... and so).

This is some really anemic looking vrm .... I seriously doubt this thing can handle 170 watts with out throttling .... Maybe is fine on a rack with the tourbine sounding fans that push a ton of air over em, but a normal desktop case I would not trust it ... Ever!

It's not for OC...
So it's really fine for what is onboard with the right PSU (if you remove the cute radiator on other brand's B650 you find most of the time the same)

4 phase vrm can not handle the stock rated 170 watts with out a lot of airflow cooling it , witch on server racks sure is there but on desktop I will say 90% of the time is not , 4 phase vrm if those are 70 amps phases it will be able to handle 120 watts most likely but if they are 50 amps .... 65 watts rates CPUs is the max I would give it if I was building a desktop system out of this .

Where do you locate the VRM on this board?
Venix
The 6 gray squares under the CPU socket , they are most likely 4+1+1 phases 4 CPU 1 igpu 1memory I am not sure if zen 4 has dedicaded vrm for the igpu like Intel so if they use the same vrm then they are either 5+1(memory) or 4+2 .
Here is msi's mpg b650 edge

16+2+1 This is on the other end complete and uter overkill ! Most likely this can handle 400 watts with the aluminum slabs MSI stuck on top !
And gigabyte's cheapest a320 mb

4+1+1 50 amps phases ... This one can handle a 65 watts CPU ... But 105 watts and over throttles to hell and back if they where 70 amps phases would have been most likely 'ok' for 105 watts stock.

Ok so it's 6+2 then, the igpu isn't used on pro board (the output are for the aspeed, not for the rdna) the vrm are on the "wrong" side due to rack use.
CPU on internal face and other between CPU and slot, and dual P8 to power it.
Venix
Oh I totally missed the other2.phases over the pcix , so I guess the vrm is 5+2+1 2 for the igpu 1 for the ram and the 2 separate ones are most likely for the zen4 igpu and the board support the igpu else they just put one HDMI and display port ... And the mesozoic era d-sub. (still widely used on s ever space so makes sense).
The I/o pic is in the article ...5 phase with adequate
Cooling like air-conditioned room + ton of air should be 'ok'
