ASUS brings Resizable BAR support to Intel 400-series motherboards - SAM on Intel?

I'm curious, If this then doesn't require a Ryzen 5000 CPU to work, Like many initially thought, I wonder if it could be implemented to work with older Ryzen CPU's and if Nvidia are working on their own implementation I wonder if it will work with both AMD and Intel or if Nvidia will end up choosing just 1 CPU vendor.

Not sure why people thought it was AMD specific, its a specification in PCI-SIG standards. AMD just have control over their hardware and are able to better implement it. Hopefully to a higher degree.

It all comes down to hardware and software validation. Poorly implementing a feature like this could result in performance reductions if the drivers and firmware are not up to snuff. That's why AMD was the only company that could create this.

Nvidia can't control CPUs and motherboard firmware and Intel doesn't have enough of a discrete GPU presence to even try this. Both are following AMD's lead here, but Nvidia will need to do a lot of driver work to make sure things work as they should.

Credit where credit is due, AMD made this happen. That said, I think AMD should have toned things down a little with their marketing. The only thing stopping SAM from coming to 400-series motherboards is firmware and the necessary validations. Not sure about 3000-series CPU though, but that could happen.

Its because AMD released slides saying that you need a 5000 series CPU, a 500 series motherboard and an RX 6000 series GPU. It paints a very specific message.

While it is an implementation of PCIe standards, AMD needed to make sure their hardware and software supported it at every stage. It's more complex than ticking a box that says "Enable Resizable BAR".

It is very easy to dismiss what AMD has done here, but could Intel or Nvidia have made this work before AMD laid the groundwork?
 
Not sure why posts were deleted here. Haven't been on in a few days.

I'll say it again.

It my paint a picture but it it's the tech media's job to inform people. Linux has had this support for a while AND amd's own drivers support it as well already on Linux. It's under the PCI specification of RBAR, and this new SAM is the same thing but works a little differently as AMD is benefiting from both of their own CPU and GPU IP. It's basically the same thing they are just rebranding their version for marketing. Never once said it's just ticking a box.


The tech media failed to do their job. Even if you did not know it was on Linux, the mere fact they mentioned breaking the current 256MB PCI limit should have prompted some research as I'm sure you didn't know of a 256MB limit hell nobody did.

Fact of the matter is the link I posted before it was deleted I found without any issue and got the answer within minutes. It's readily available information.


Amd laid no groundwork here. Nvidia need to support it in drivers. Intel needs to do all the work to get their platform to support it. Amd talking about it helps neither one out. It's a specification they all optionally choose to support or not. Now they all are because one of the 3 is. It's marketing and now they all are trying to not be last so they can market how their version is best.
 
They probably had to roll back forums due to:

But about RBAR, it has been a thing for a while, but it hasn't been stable, nor has it given a notable performance benefit. Sometimes it can even lead to worse performance. So AMD needed to iron out issues and just disable SAM from software which don't work well with the technology on driver level. And seeing that it's a tech worth ~4% perf on average, it's understandable that other vendors haven't really bothered.
 
Nothing was deleted intentionally. The forums had to be rolled back to December 2nd, as has the main website.

We will have a post up tomorrow to explain things in more detail. Long story short is that a hardware failure at the site's host took the site down for around two days. Some things still need to be fixed.

The good thing is that despite practically everything going wrong, the website is now live again.
 
Oh my apologies. I've been without power and internet in my town for a few days. I am slowly catching up to the world. Crazy how much information passes by when you aren't looking every second...
