@mini-i5, MicroCenter sales guy was telling me how great of a deal this way. I nodded in agreement and said "Relatively, yes". The next lowest cost RX 6900 XT graphics card in the store was an AIB, MSI Radeon RX 6900 XT Gaming X Trio Triple-Fan for $1,919.99. The naming of these GPUs are getting ridiculous too; try saying out loud the full model name of these cards.

@itsage, Ha ha, yes. 

More savvy GPU model naming schemes, and overall company re-branding efforts seem like pressing issues for AIB GPU partners - given how they solely offer Luxury Lifestyle products. 

Below is retail store pricing in my area for a variety of coveted Luxury items you can pick up today.

Some are available at one of the US's premiere luxury-boutique-store shopping malls.

The rest are sold at the nearby 1990's era MicroCenter located in an industrial / mega office park.  

Here are the (walk in the store and lay down some cash) retail prices:

$2,100

$2,250

$2,250

$2,260

$2,300

$2,500

$2,600

Ok, so here’s the test: which prices are for RX 6900 XT graphics cards? 🤔

And which prices are for a Tiffany diamond pendant necklace, a Dior calfskin pouch, a Louis Vuitton carryall shoulder bag, and a pair of Channel calfskin knee-high boots? 🤔

Not so easy to guess the right answers.

Good afternoon. I have a Mantiz MZ-03 Saturn Pro II EGPU. Direct connection of the Apple LED Cinema Display 27 through a TYPE-C adapter to the rx 6800 xt video card does not work, the monitor does not turn on. Does anyone know what could be the matter?

@pavel, What's the specifics on the USB-C adapter you're using? The LED Cinema Display (27-inch) needs miniDP monitor input so it may be more straightforward to go with female mDP to DP adapter.

@itsage, I use the original adapter from Apple. I tried through the mDP to DP adapter, it also does not work, does not see the monitor. Monitors only work if they are connected directly to the MacBook.

What else could be the reason?

New AMD offerings on Mac Pro have gone live.

Also hammers home the previous info kicking around that there won’t be any 6700xt support.

@philw, Cannot believe prices are all the way to the SUN. Wow.

Any news about whether XTU chipset will support ?

@mkzayar, Personally I feel that unless there's a real need that its unlikley to come from Apple. Everything we get supported for eGPU is an accidental byproduct of what they need to support in the Mac Pro.

My gut feeling is that this is the last real AMD development we will see whilst they cook up an uber core M*whatever. I'd love to be proved wrong and see eGPU / PCI-e enabled in some future M-series machine but I do feel like its unlikely. The hope being it is engineering time on ARM AMD drivers required and not a marketing decision.

So I just got a RX6800 but it in the Razer Core X Croma with 750W PSU connected to my 2018 Mac Mini … previously my Radeon VII and currently until I got the new card I used a RX5500 8GB … all worked fine with no issues but with the RX6800 I have issues with reboots, kernel panic’s after restart and so on … basically I can’t restart, I have to shit down the system, power down everything, wait for a minute or so and start the system … most of the time it works fine after that … anybody else has those kind of issues or might there be a problem with my copy of the GPU

@fcpxusergermany, Certain cards hang macOS bootup if they have compatibility issues with the Mac firmware. Which brand and model is your RX 6800? Does it have a vBIOS switch you can test?
