As announced by Nvidia, here:
https://www.nvidia.com/en-us/geforce/news/geforce-rtx-30-series-resizable-bar-support/
 
So it's launching in late February, only on the 3000 series GPUs
They specifically mention Intel 11th gen and "select" 10th gen CPUs, and only a generic statement that they are "working with AMD". Hopefully it will come for Ryzen systems as well, and not like AMD did, on 5000 series only. 
 
It would seem Motherboard bios update is required (already got that) but also video card bios update as well. Hopefully EVGA will supply that :)
 
Free performance boost is always welcomed.

It seems there is a lot conflicting information about this.
On one hand there is the hardware limitation thing on AMD side mentioned on tecpowerup . On another, there are screenshots floating around on the feature working on 1st and 2nd gen Ryzen systems on motherboards from Asus and MSI.
I also recall an article somewhere with a board integrator saying that it is in fact possible, can't recall where.

My particular board (Asus x570 tuf) already has the feature integrated and functional for AMD cards. I just hope it will work with Ryzen 3000.

Right now, considering the said conflicting information, I start to wonder if it's not in fact artificial limitations imposed by marketing teams, in order to further differentiate product stacks.

I guess we'll find out soon enough.

we all gonna be forced to switch to 11 gen sadly, my 9900k will probably dont get support

10th gen bios has already been updated, so you probably assuming wrong. 11th gen will have better support, for sure, but multiple motherboard manufacturers already enabled in on their z490 boards, so now it requires Nvidia to send out a new bios and new drivers.

if he has a 9900K then he’s likely screwed. NVIDIA was very clear only 10th and 1th gen support from Intel. He’s got 9th gen so he’ll have to upgrade.

i wouldnt worry about it to much. it probably wont give you much more performance. i wouldn't sell a 9900k setup over 1 or 2% more performance in some applications. even amd has said there infinity cache only gives an extra 1-3% in most scenarios. gamersnexus has tested this if im not mistaken and only got 1fps more in some games but it didnt matter because 1fps is within margin of error. with a solid overclock you would gain much more 

Will they add support for workstation chipsets like the C621 and WRX80?

I totally agree. Also, you got to wait for that feature to come into place and see exactly how it performs, you might not see a whole lot of gains and you'd be surprise how many things can get broken along the way before it gets to full maturity.

From free performance boost to bricking card and mobo with questionable RMA results its only one power cut or other accident away. I would be very very VERY cautious esp after what I went through with my first 3080. What are you playing anyway that you need further boost?

 is the Resizable BAR really effective？
