Question about Zen4/5 max resolutions (and Win11 AI compat, too!)

So my beloved Threadripper 1920x is still going strong but with its 7900XT GPU, its 4HDD, 2xSSD, 3x NVME and 8 RAM sticks… It’s a power-hungry chap. And frankly I no longer do the sort of hands-on development work I bought it for. I’m looking at maybe a 65W Ryzen 9 7900 or perhaps I’ll get one of the upcoming 65W 9000 series. (Or could be tempted to go up the 120W version - will still be a big saving). Mostly what I need these days is a zippy desktop experience and most of my heavy lifting and storage is in the cloud these days.

Sorry - bit of a rambling intro. What I need to know is if the onboard graphics of these CPUs will be enough to drive my 5K2K monitor (this one). It’s only 60Hz. Whether the CPU can support this is critical for me - it determines whether I can get away without a discrete GPU or not. And if it does, do I need to look out for any particular features on the motherboard to support a monitor that large as well?

And if I can sneak a side question in here as well, I’m going to put W11 on this thing. I know it’s controversial but the CoPilot AI features they’re releasing. I see on laptops there’s a requirement for a 40TOPS NPU now. The desktop chips don’t appear to have that. Does the GPU serve the same roll and are they good enough? I would like to have the option of running this feature on my new build.

Thanks for any answers, sorry for wordy post!

I never did get any answers to this. Either nobody knows or more likely I was just too wordy. :slight_smile: But with the new AMD chips released today, I’m trying to plan out my build.

The question is basically: Is the 2 core GPU in a Ryzen 9700X going to be enough to drive a 5120x2160 monitor at 60Hz. Non-gaming, desktop and office usage.

I’d love to be able to have my new system manage without a discrete GPU but it’s such an edge case for home-builders nobody seems to discuss it.

absolutely, not a problem (tested with 49" ultrawide maybe 3 weeks ago)

didn’t see it, i just lurk the top posts and try to jump on unanswered threads

Thank you so much - it’s great to get an actual verified case. Was the resolution same as mine (5120x2160) or was it (5120x1440)? So that was pure CPU, no discrete GPU? And do you recall what Hz it was running at?

just asked my lead tech
“exactly dual 2560x1440, so 5120x1440…” 60 FPS playing our demo loop which is a mix of 2k and 4k footage in VLC plus some YouTube 4k scaled at the same time.
And yeah, a 7900X we had as a demo build without a discrete GPU

Okay, so it’s a bit lower resolution, 60% of mine. The closest to a confirmation I’ve got so far, though. Thank you again.

I think you just need to check displayport versions.

According to techpowerup the 9000 series has the same iGPU as the 7000 series which supports displayport 1.4. Motherboards will also list displayport and HDMI version info on their spec sheets.

If your monitor also only supports up to displayport 1.4 then it should be supported by zen 4/5 iGPUs but if your monitor supports a displayport version higher than 1.4 then it may not be fully supported by zen 4/5 iGPUs.

And it looks like nVidia GPU support will added in the future for CoPilot AI.

@Hondo, you might consider removing Copilot and another new feature that Microsoft is forcing on its customers called Recall. From a security standpoint, installing both of these features could lead to serious security issues in the future. Copilot and Recall are why, in the future, all my Windows 11 devices will be run as virtual machines, isolated on their own network, and treated as potentially compromised environments.

I’ve actually moved on from that since posting and will probably shift back to Linux for my main system. I prefer Windows in many ways but as Wendell said recently in that video with Steve, Windows feels adversarial now. It’s sad because in many ways I find it superior (obviously not with super high core numbers, LOL!) but Microsoft are fighting me more and more.
