I know this is a weird request, I have 1 rtx-a4000 for my up and coming workstation.
What is better than 1 rtx a4000… well two 
A quick and lazy google I cant pickup any benchmarks when running 2 of these cards, anybody have any thoughts or experience with this ?
has anybody here done it?
I know the rtx-a4000 does not support nvlink, so memory wont be pooled/combined…
but the nvidia driver is clever enough to use both cards right ? as in from a processing point of view
?
The applications has to be able to utilize them both, this is a typical thing for renderers.
I observed something that i thought interesting, my daily work pc is a lenovo thinkpad p15 gen2, 11850h cpu, nvidia quadro t1000 graphics, obviously has onboard cpu graphics also.
if the laptop display is the primary display, i get a 2dscore in passmark of about 500points…
which is about right for the card.
when i make the asus proart monitor (connected to t1200 via hdmi) my main monitor. I then get a 2dscore of just over 1000points. which is pretty good.
on another machine I ran the nvidia a4000 and 2dscore is 600-or so…
When i do the above, i suspect the benchmark is using the onboard graphics + the t1200 which combined give the 2d score.
we know theoretically somethings what should happen, but in practice its sometimes a bid different.
pretty sure blender and the likes will beenfit from 2 x a4000 cards, but itd be interesting to see realworld how all sorts of other stuff benefit or not…
e.g would my timespy score improve ?
someone with access to 2 x quadro cards… can be a6000 or a5000 also, let us know realworld what happens
I don’t have such a setup with dual nvidia cards, but I know blender can do multigpu and scales quite well at that, with the limitation being the ram.
In luxmark where both my radeon viis can be utilized, I get a score comparable to a 3090. I do realtime stuff though, so I utilize the cpu mostly.
I’m not sure if allowed to post a video from another channel, in this case I think the information given is beneficial.
