Question Graphics Card to drive *SIX* 4K monitors

[ballerboy]

I am planning to build a new AMD system (CPU: AMD 7900X, Mobo: X670E Steel Legend, 64GB RAM)

The system will drive *SEVEN* 4K displays (SIX 32” 4K monitors with DP inputs, and ONE 75” 4K TV with HDMI input)

Here are my requirements:

1) The system won’t play games, is mainly used for productivity / web browsing / financial markets trading / light video editing.
2) System should be as “low power” as possible, therefore would prefer card with low power usage
3) Hopefully looking for cheaper priced graphics card (whilst still being able to output to *SIX* 4K displays)
4) Most important is RELIABILITY, system must to be STABLE with low risk of crashes


I already understand the below:

-I will be able to drive at least one (likely two) 4K monitors directly from the iGPU in the AMD 7900X, from the DP / HDMI ports on the X670E Mobo. Therefore, the Graphics Card will need to drive the remaining *FIVE* or *SIX* 4K monitors.
-Maximum of two displays via HDMI, the rest must all use DP
-I understand that most graphics cards only have 4 outputs (3*DP, 1*HDMI), therefore I will need to purchase two MST hubs to drive 5th and 6th monitor
-Likely Radeon RX 6000 series would be a good choice, I understand they can output to a maximum of *SIX* 4K displays?


Here are my questions:

1) Is Radeon RX 6000 series best choice for my needs?
2) What is the cheapest / lowest spec RX 6000 card which is capable of driving *SIX* 4K monitors? For example, would RX 6600 be “good enough”, or would a higher spec card such as RX 6800 be needed?
3) Any other requirements which I should watch out for? For example, for graphics card memory, is 8GB enough, or would need 12/16 GB?
4) For MST hubs, any recommendations for stable, reliable, relatively low-priced model? (which can split a single DP input into two, to drive two 4K monitors)

You should be able to drive one display at 4K res at 120Hz, per the motherboard's specs. You could be able to drive two displays at lower frequency but at 4K res at 60Hz.

You might want to explore workstation cards, with mini display ports for your needs.

Thanks for the replies everyone. I would prefer to rely on integrated graphics as much as possible (I want system to be super stable and low power)

I was searching around on Google and saw that AM5 (Zen 4 and Zen 5) CPU integrated graphics can support a maximum of FOUR displays, can anyone confirm if this is correct? (I will likely buy either 7900X or 9900X CPU)

Of course, another problem is motherboard also needs to have enough ports to connect the displays (using integrated graphics).

I see that X870 motherboards will likely be released around 30th Sep, I would be happy to wait around until X870 release.

(No particular preference for Gigabtye, would be happy to consider any Mobo manufacturer)

I see that most Gigabyte X870 boards have 3 ports for onboard graphics: 1*HDMI (supports 4K @ 60Hz), and 2* USB4 Type-C ports, supporting DP (supports 4K @ 240Hz).

I wonder if it would be possible to use MST Hubs to connect *TWO* 4K monitors to each of the USB4 Type-C ports? If so, it might be possible to run a total of FOUR 4K monitors directly from AM5 integrated graphics?

Or if not, worst case scenario could run THREE 4K monitors directly from AM5 integrated graphics? (2 from USB Type C, 1 from HDMI)?

Just a thought for you:
Consider using three 48" 4k tv's.
The display space would be the equivalent to two 32" monitors.
That would require only 4 connectors, and perhaps make mounting such a wall of displays easier.
Using integrated graphics, you might be reduced to 32hz and not the 65hz or greater that gives a good image.
Before buying all parts, you might want to test buy one unit.

Just get a pair of these and DP to HDMI cables. You just need a board with a few PCIe x16 slots.

There are a few cards that have more connections, but they are more expensive/older and lack VRAM.
