Does Sam work with intel

[Ebony Falcon]

Yo,

does smart acces memory work with intel cpus ? And does it work as well as it does with a amd cpu ? 
becuase from some benchmarks iv seen Sam puts the amd cards into a different tier

As far as i know... rebar "works" for all the connected graphics card that supports it. AMD, nVidia, Intel.

 

Not a thing for iGPUs

No.

 

Rebar is an Nvidia thing, but it don't have nearly the impact SAM does with Radeon.

Doesn’t rebar work with amd and nvdia ? But it’s  just better with amd cpu and gpu combo ?

That’s what I thought, but is it better with amd + amd than intel cpu+ amd

As far as I can tell, no, the performance uplift is about the same on both. 

 

As for whether you can enable it, the answer is yes:

Not true. SAM is just the marketing name for resizeable BAR, there's no "special sauce" that AMD implemented when created it. AMD's architecture was just designed around the use of ReBAR, therefore it has a bit higher performance scaling than Nvidia's cards.

 

If you want proof of this, look at Arc, it's an architecture designed exclusively around ReBAR, and when you disable it performance tanks. AMD's architecture is just in the middle, where you get a decent performance uplift by enabling it (5-10% on average, sometimes higher), but still very good and usable performance without.
