Apple is likely very aware that fully supporting the potential of RDNA 2 GPU's could hurt their future Mac M-Series sales. This would mean instead of upgrading to the Mac Studio they would just upgrade to a new RX card. Personally, if had the newer Mac Pro that was insanely overpriced then i would somewhat justify the price by upgrading to a fast RX card because i use Blender and Unreal Engine.

This comment should be pinned.

Cinema 4D is the only application i think would benefit from a GPU upgrade but that's assuming its GPU dependent like Blender. The other applications are more CPU dependent (i think) so in your case you actually have over-kill hardware because the iMac is only going to utilize what its needs.

Stick with an AMD reference card manufactured by AMD, not a partner card. Nvidia GPUs ate nearly impossible to get to work as an egpu with iMacs

This isn't true at all. If your mac has an Intel integrated GPU, ANY discreet eGPU will make your system noticeably faster. Those Intel integrated GPUs are absolutely horrible. With an Intel integrated GPU on an Intel Mac Mini, you can't even run a single 4K display with scaling turned on without the user interface lagging when the UI animations are going.

@@5urg3x I'm not comparing it to an iGPU. I'm comparing it to a dGPU. All the same, it's an extremely poor performing and expensive solution. ASUS proprietary version that connects straight to the PCIe bus is different though. I'm talking about USB4/Thunderbolt 4.

@@henrikg1388 In many situations, even a 16x PCIe connected dGPU is not utilizing the full bandwidth of that PCIe link. It really depends on what you’re doing. Also, most Intel Macs sold did not have dGPUs. The Asus solution is still PCI express version 3, but it’s 8 lanes instead of 4, so instead of 40GT/s, it’s now 80. I also don’t believe it’s tapping directly into the PCI express bus, it’s more than likely simply combining two thunderbolt / USB 4 ports…which is something Intel should have allowed from the getgo, but unfortunately didn’t. I’m not sure what their reasoning was. Probably Apple had a hand in that, thinking a dual cable solution wasn’t “elegant” and not wanting to have thicker cables that were even more length limited. Anyway, the faster link speed should help, but again, it really depends on the workload. If you’ve got a workload that is GPU bound and heavily optimized, and isn’t using the CPU or system RAM at all, and is doing everything on the GPU (like crypto mining for example), 40GT/s is more than enough bandwidth. OR if you’re running CAD or 3D modeling software, it should be fine too. The problem with gaming is you’re constantly swapping data from system ram to vram, and having to utilize both the CPU and GPU together, so yeah, with that workload, it’s better to have the fastest link possible.

windows is garbage OS tho

@@hwy9nightkid , garbage? CGI, 3D modeling and video editing professionals still use Windows + NVIDIA. Apple is garbage in general when its comes to real workstation use. You are an idiot to spend +$3000 just to equal a low priced Windows alternative using a RTX 3050.

NO

Have a great weekend

Hoo wooda thunk

Nvidia 3000 series dont work in boot camp.

Yes

Could you manage to improve 4K gaming performance (fps) in bootcamp? And how did you set it up working? Most people report that as long as you use iMac internal monitor in bootcamp gaming, eGPU is just useless due to the huge performance bottleneck in loopback mode. They say that thunderbolt 3 and iMac’s internal monitor limitations kill the idea of eGPU.

I’m curious how you got it working. 5K at 60 FPS?

Hi. How do you use a 3090 in iMac Pro? Nvidia drivers are not available for Mac, right?. I´m testing a Radeon RX 6900 XT that Mac recognize ok. Thank you

Cross over? not well though I would imagine

@@TallyHoTech Yes

@@TallyHoTech Runs pretty well

Which is crazy to believe, I'm running it on my m1 chip at 30 fps
