Seems like they want to lock it to their new processors as long as possible. And once Nvidia start actually supporting it, then they will open support to all CPUs.

Hopefully they'll make it available to the 3000 Ryzens. I don't see much of a reason to have it be 5000 only (if it is supposed to support Intel at some point).

I have a feeling since nvidia stated their gpus will support this as well as this is a direct x feature and they will support it on both intel and amd as far amd does not lock em out.... They are jumping ahead to show that they are the good guys and they are sharing ... Or i am too suspicious

On other hand Freesync have been proposed to both NVidia and Intel too...
None have used this opportunity.
The gain for AMD is to become standard, this way even if concurent sold more it is still a gain.
M$ have done this with Android and Apple, they were in the end wagon of the train, but still earning a lot.

If AMD think this will gain them any favour in future from intel or nvidia they are very much mistaken.
Its a foolish gesture that will not be replicated.
AMD are lacking enough features. Giving away r and d is just foolish.
Just look what nvidia did with AMD freesync. It no longer belongs too AMD.

I don't think AMD had any choice. Especially after Nvidia reported they had showed similar performance gains with their RBAR experiments and would work to enable on Intel motherboards, and if not blocked AMD motherboards. Nvidia and Intel were poised do the same lockout that AMD tried to do.

I might be wrong, but I don't think this has anything to do with DirectX. According to Nvidia, it's a PCIe 3.0 feature, if memory serves. It also requires a specific bios setting, which further suggests it's not related to DirectX.
It would be beyond funny if this feature turns out to be more widely supported by Intel/Nvidia than AMD, which actually used it in their marketing. But that only depends on if AMD keeps limiting it to the 5000 series.

Some games crashes after installing SAM beta bios MSI x570 Mag Tomahawk mobo ,after deleting the game preferences for those games they worked ok
Graphics card: GTX1660 Super OC, but i don't notice any improvement....

It should not work yet. Nvidia and AMD have not submitted their driver updates to enable the feature. So currently it will only work with RX 6000 hardware on specified motherboards.

This is a PCI express feature, everyone with a PCI 3.0 and a compatible motherboard (bios option "resizable BAR" required) should be able to use it.
Windows is compatible since WDDM v2, so Windows 10 only.

Both AMD and NVIDIA utilizing it should mean both vendors now unlock it across more hardware and the feature gets wide availability though AMD started with the whole 5000 series CPU and 6000 series GPU but at least it's picking up pretty quickly and with a few new driver revisions and possibly from AMD also further bios updates there should be some interesting results as this feature gets tested out. 🙂
Bit of a different thing but I am still curious if the ability to send more data chunks or rather larger data chunks could also benefit Direct Storage but that's not something we'll see for a while yet. 🙂
EDIT: Suppose using it as a hardware feature to promote sales is a thing from AMD plus you'd probably want to start with a small sample first although this does sound more like it's down to motherboard and PCI bridge quality and the chipset more than CPU or GPU although cache and CPU features could still play some role or certain GPU functionality for all I know.

don't get too excited or waste your time with this
check youtube video comparisons you'll see the fabled 3-5% improvements are actually 0-5fps on already 100+fps games 0 more often than 5 too
it's something that might give us an increase maybe, later...but right now it's not worth even mentioning
asturur
I think you are suspicious.
This isn't windows related library.
This enables access to the gpu memory without pagination, is a MB/CPU configuration probably in the way the address space is configured.
I think is at UEFI level and then you probably need to take advantage it in the software.
Can it be wrapped by a generic directx implementation? yes.
But that does not it mean that is a directx feature.
asturur
I still ask myself why is x570 only and not b550 too
schmidtbag
Right, I would understand why it'd be limited to the 500 series boards, but not only the X570.
Sylencer
Im down! Hopefully Intel doesn't only include this on newer board or cpus.
rl66
Freesync is AMD and Gsync is NVidia both are sync but it's the only thing they share and both are derivative from the same work that is free and neither from AMD or NVidia.
(also it's like searching phase for HiFi those who know how to do don't need an automatic tool to do it... those sync are useless)

The element behind SAM is the RX-6000 series "infinity cache," specific to the RX-6000 series. It would have been nice to see a link to the interview you cite, HH! Don't know if nVidia has an equivalent--and of course Intel doesn't make any discrete GPUs to compete with RX-6000 or RTX-3000, either--so that's going to be a bear to program for them. I am, however, conversant with nVidia's promising to include features that competitors have but nVidia doesn't...uh, about which, a long time later, nVidia sheepishly says, "We couldn't get it to work--but, but, but our new GPUs have it, yes indeed..." This goes all the way back 3dfx's use of 8-bit palletized textures with the V3 which the TNT/2's didn't have. But that didn't stop nVidia from claiming that the feature was there but they hadn't "turned it on in the drivers yet"--that makes so much sense, doesn't it? [not] After the successor to the TNT2 was shipping nVidia stated they'd been "unable to get the feature to work" with the TNT2, aw shucks. Things like that are hard to forget--at least for me. Anyway, with respect to SAM, my thought is that a bird in the hand is worth two in the bush. (Clever, eh?)
Stormyandcold
Well, I liked the idea as soon as I found out about it. Hardware is expensive as it is and tech like this helps to extract every last bit of performance.
stormy
Not that Ican make use of if, but there is a SAM enabled beta for my B550 Tomahawk.
