Additional graphics card - works or stupid?
Something just occurred to me (possibly because it is almost 5 a.m. And I should go to bed), but I don't yet know whether that works or was just a stupid thought.
I have two graphics cards on my old laptop. The weak one regulates, for example. Internet and the better then the games. Then performance is actually good.
I have a GTX 1080Ti in my computer and wanted to install a second, albeit weak, graphics card, similar to the laptop.
I found the GT1030 with 2GB DDR5, it only has a heat sink - no fan. Heard that these use practically no electricity.
I can connect a second card to my mainboard. Does that work at all, that is, that I have the 2GB more and at the same time use it for simpler applications and the 1080ti for games… Or am I just stupid straight?
A few more general information about my PC:
B450 motherboard A.
AMDRyzen 5 5600X 6x 3.70GHz
GTX 1080Ti MSI Aero 11GB
be quiet! Dark Rock Pro 4
be quiet! Shadow Wings 2
1000GB M.2 SSD
32GB DDR4-3200
700 watt power supply
You can install it if you have a 2nd Pci Express 16-way connector on the board. However, a separate monitor is then necessary. Internal monitor switching such as dedicated GPU to onboard graphics does not work
The 1080Ti needs less than 15 watts when surfing or watching videos… There's not much potential for savings anyway
The 1030 actually does not need a power cable - only the graphics card slot on the mainboard. It's plug-and-play, so to speak.
Does this information make a difference? Can they then run for all applications at the same time or these 2GB as a "reserve" for the PC?
Yes, but you shouldn't do it with 2 different GPUs. You don't get any extra performance and your VRAM won't work anymore either. It can even be more likely that you will get a loss of performance because your CPU has to take care of a GPU more.
I also don't see the point in how a cheap GT1030 could relieve the strong 1080ti of any loads.
I actually don't care about power consumption, it doesn't matter at the moment. Do I have more graphics memory then? The real question is:-)
Take a look, the 1030 also needs about 11 watts when surfing and the like.

The cards can't be completely deactivated. And switch off as long as it is plugged in.
Thus, even if you only select the 1030 as the active card, you would come well above the 15Watt of the 1080Ti…
If the 1080Ti only has 2D applications running, e.g. B. No power at all via the separate power plug because the Pci 3xpress port can deliver up to 75 watts of power…
Thanks for the information!
So would such a project only work with 2 identical cards, if at all?
Ne the graphics memory of two cards can't be combined… The performance also not with 2 different cards
I'm so tired I just don't understand how many watts what has and needs…
Take the better GraKa. Then you don't need the cheap one anymore.
This is also unnecessary, because here with 2 1080Ti, the performance does not double but in the best case only increases by 1/3 and this so-called SLI is no longer supported by games.
Basically, this could work, even if you then combine an iGPU with a dedicated GPU, like with a laptop.
But doesn't make a lot of sense, since the 1080 Ti also clocks down while idling and then doesn't use as much power as it does under load.
The constellation would make more sense if you were to play many games that have PhysX support. Then the GT 1030 could function as a pure PhysX accelerator and relieve the 1080 Ti.
Or if you have many screens, you could of course connect additional screens to the GT 1030.
However, nothing more is possible with the constellation. So neither can the two cards work together, nor can the GT 1030 somehow pass its VRAM through to the GTX 1080 Ti.
