Graphics Card to drive *SIX* 4K monitors

Hardware Hub GPU

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 (3DP, 1HDMI), 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)

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: 1HDMI (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)?

Good first post from a strange username

A pair of 60watt workstation cards would easily handle what you are describing, but if you start needing higher refresh or offloading decompression a pair of 4060/RX6000 cards will happily do you.

For configuration:

These are at odds with each other.

Mixing integrated graphics and discrete GPU’s seldom works the way you want it to and just results in missing system RAM.

Get a pair of cards with 4 outputs and move on.
Could be done for a few hundred $ brand new.

Sounds like a 2x3 Video wall + 1 auxillary.

Matrox.
They specialise in Video-walls for controll rooms and the like. Can’t have your control-room go blank, ever!

No, Quadro, Radeon Pro or Matrox would be the right choice.

I only used a Matrox TripleHead once, was a solid bit of kit.

I didn’t even consider this in an enterprise environment as he was tryin to utilize onboard

If Enterprise,
then
