L'image du jour : il installe une GeForce RTX 3090 dans son Mac Pro 2019
Techniquement, rien n'empêche les propriétaires de Mac Pro d'installer une carte NVidia dans leurs machines : elles possèdent des ports PCI Express…

Mostly rumors, but second batch is supposedly coming mid October, which is great since AMDs, Big Navi seems around the corner as well, so its good to have a little Bit of extra time to see what happens
Today i installed the EVGA RTX3090 FTW3 Ultra GPU into my Mac Pro , there is much better Performance.
Compared
3090 FE = 2.2 Kilogramm Massive Build Quality looks very Stylish inside MacPro
3090 EVGA FTW3 Ultra = 1,8KG also Massive Build Quality but very Good AIR COOLING
3 x 8 PIN POWER Plugs = upto 470WATT Possible
Extreme Stable Overclock Possible
aRGB Light = can be complete Turned Off via X1 Software.
Max TEMPS under OC Full LOAD = 73 Celsius
No SAG
The EVGA is worth the Costs.

With an RTX 3090, will I be able to drive a Pro Display XDR with a Moshi DisplayPort to USB-C bidirectional cable?
@smgfreak thanks for your various posts on the 3090s. Going to try out the FE myself when it arrives on Tuesday, but was curious if you had done any tests on various output video options? I'm curious how the RTX handles Thunderbolt 3 displays mainly, and if you had tried the built in ports for video outputs. With the AMD cards, there seems to be some rerouting support in both Windows and MacOS, so you can plug in a Thunderbolt 3 display into any available port (on the top of the case, the built in card, etc.).
Did any of these tests work for you?
Thanks!

RTX doesn't have Thunderbolt so it won't work with Thunderbolt displays unless the display supports non-Thunderbolt connection (such as latest LG UltraFine 4K and 5K displays) or if you pipe the DisplayPort output of the GPU to DisplayPort input of Thunderbolt 3 add-in card.
No. Only MPX cards have the connector that allows DisplayPort output from GPU to the two built-in Thunderbolt controllers in the Mac Pro (top and I/O card).
I suppose it could be possible for a third party to make an MPX slot adapter to allow a normal GPU to send DisplayPort to the Thunderbolt controllers so you wouldn't need to use a third party Thunderbolt 3 add-in card.
Ok so If I get an RTX 3090, will the Belkin Charge and Sync Cable for Huawei VR Glass theoretically XDR display?
One thing is that the RTX 2000 series have Virtuallink however there is no USB-C on the 3000 series which makes me wonder.
I'm very much interested in this cable:

Hopefully this will eliminate all the headache with the Nvidia cards without sacrificing XDR control.

^^^^As I posted Waaaay back in Post #97, I'm running this cable with my Aorus RX5700XT to my LG UltraFine:

No longer will you be limited by the direction of your cable! This Bidirectional USB-C? to DisplayPort? Cable allows you to connect your legacy DisplayPort devices to your newest USB-C enabled display

The Belkin cable uses DisplayPort as the source - doesn't need Virtual Link. These cables work to allow 6K because the GPUs support DSC.

These cables don't give brightness control, presets, audio, camera, etc. because they do not have USB.
Hi @joevt, thanks for the reply. I've followed many of your technical posts in other forums re: add in cards and such, your advice is very helpful. I am trying to research a way to display Windows on my LG Ultrafine 4K (the new model which I believe supports USB-C alt mode) while retaining speakers/brightness control/usb hub on the monitor if possible. Would the Titan Ridge card + display port cable connected to a 2080/3080/3090 DisplayPort output and the Titan Ridge, along with a thunderbolt 3 cable from the Titan Ridge to display, allow me to achieve this?
this would be awesome, though I doubt there'd be much demand for such a card. IMHO, rerouting video signal throughout the machine's available ports would be a massive enhancement for case design/options.
It might work if the Titan Ridge is flashed. The connection would be Thunderbolt instead of DisplayPort Alt Mode, so it may be problematic. Using DisplayPort Alt Mode with USB would have no issue. In Windows, you can install the Boot Camp drivers for brightness control. Normal USB audio drivers will work for audio.
