Wow,
2800$ for a W6800X... expensive...
What would be the main difference in performance from a regular 6800 XT?
 
I mean the W6800 MSRP is $2249, what were you expecting? The MPX is a workstation card not a gaming card lol

The non MPX W6800 is already like $2200-$2400, so mostly the MPX adds some - with TB3 ports. Vs the regular 6800xt, you get 32GB of vram vs 16GB as well

If MPX or any kind of GPU works with a theoretical AS based MP8,1 / MP9,1 style machine the investment may make sense for a lot of people. Without that clarity, it is a tough path forward. Yes, you can theoretically resell but if you're upgrading from an already upgraded MPX GPU it feels a bit like a gamble.
 
Not gonna lie, am still happy with my comparatively cheap 6800 XT, however as I've got a Pro Display XDR, there's something to be said for adding the W6800X Duo and then just riding off into the sunset with all those compute units.

This. Memory bandwidth matters for crypto and the infinity cache doesn’t help.
Not that these are a good idea for this - but do you think the W6800x/6900x will perform similarly to their gaming counterparts in crypto? Any advantage memory wise that may make them closer to the Vega ii or likely not?

Looks like they have the same 512 GBps bandwidth as the consumer parts, which implies the same clock speeds and bus width for the memory.

Was able to see the cards briefly on the Australian store before it's gone to "be right back", still shows up in Google search though.

AU$4200 for the W6800X 32GB compares very favourably with the pricing for the regular AMD W6800 whivch is about $4500, with obvious benefits for Mac Pro users (TB3, MPX) plus is actually available for delivery in a few days.

AU$7500 for the W6800X 64GB Duo seems interesting too. $9000 for the W6900X is less so.

Will be interesting to see if FCP picks up any further optimizations for these new cards. With Apple's generous return policy it's tempting to see if it offers improvements in my workflow.
 
Yeah, they are all priced where I would imagine them to be, except for the W6900X. For some reason I can’t figure out why it is such a significant price difference with that one GPU as the performance doesn’t seem to justify it.

even the W6800 duo, which is likely in some cases a faster GPU, is cheaper. Can anyone theorize why the price gap?

it kind of feels a little bit like it’s just to have the most expensive GPU with a huge margin, for the few that may want to buy it.

The typical 20/80 rule.

Last ~20% performance cost ~80% more 🤣
 
I definitely dont understand why the hell you would buy a 6900 over a dual 6800 ? more power, more ram for less money? is there one professional software now that dont handle multi gpu?
then of course the debate is : are the extra thunderbolt port and tight integration worth the extra price over a PC version?
in the case of the Single 6800 or two 6800, I gess a couple of hundred to get the real deal might not be that bad…
but regarding the 6900, I find it hard to bite… unless the w6900x actually have a trick in her sleeve such as HBM2 memory instead of ddr6…. and then, still … who wants to pay several thousand more than the PC version???
those prices are probably to make as much margin on big customers… but will eventually come down after a while… unless the do it on purpose to be able to say : « seeeee weee gave you pro **** you asked for but you darn cheap bastards woooonttt pay wa we ask for dawg , we aint do dat **** no more , just buy our 3000$ m2
macmini that can do it all and shut up! »😂😂😂
 
There's no general speedup for going multi-GPU, it's all depending on what the software does with them. Multi-GPU seems to work well enough in compute mode on the Mac via Metal, however I am not aware of a single application making use of hardware-accelerated 3D graphics across more than one GPU (not on Mac and neither on PC in fact). So if you want the fastest available for that kind of thing then you are better off with the single higher end model.

Question is who does 3D on the Mac and is that hard pressed to squeeze out the maximum framerate but that's a different topic. 🤔

I dont do 3d but live broadcast requier us to sometimes export on the fly and minutes sounds like hours when the director ask « are you done exporting that clip? »😂😂😂😂

ASICS are always going to be faster in that case, right?

nah, we need out the the box widely avalaible software…
our machine need to be reliable swiss army knife workhorse.
any gamer pc or linux server on amd would be faster but to our experience nothing beat a xeon under mac os for the « plug it and get the work done » peace of mind.

I guess I just find it weird for video work to rely on compute performance when the onboard ASIC on the GPU‘s are faster.

If MPX worked with an AS "Mac Pro" machine, this is an investment. If MPX is stuck on MP7,1 this is a heavy doorstop destined to fail on sales generated because of this exact argument. A little transparency from Apple might even make them some cash... Personally would likely stick with a standard PC version unless this is clarified. (That being said, I'm largely on eGPU these days and pandemic hurt keeping me out of purchasing these short-term.)

Sounds like you are clearly in the GPU compute camp then and a case for the dual 6800, assuming exports are GPU accelerated and there's no bottleneck when writing out the files.

This is such a ridiculous argument. You're investing in equipment now that will last for many years, just because it won't necessarily work in the next machine, hardly makes it a "doorstop".

I, like many others here, have already paid for our Mac Pro's in the work we've completed since purchase, everything after that is gravy, and the suggestion that it's worthless simply because a newer model comes along is just silly.

People are still paying actually money for 5,1s :apple:

I would appreciate some information from people with 6800 or 6900 GPUs (non MPX)
I Want to have two 6900 non MPX in my machine, but I will remove all the MPX GPUs, I don't have space to have 3 GPUs.
I only have 4k monitors, so it should be ok.
How is the experience with non MPXs GPUs in the Mac Pro? Is everything normal? Booting screen, working with Adobe or Final cut? I would love to hear from someone about his or her experience.
thank you in advance.

^^^^I use a vanilla RX6800 AMD card. I also leave my Pro580X plugged in, just in case. I use it with a USB-3 cable to my LG Apple monitor. I don't use FCP, but do use PS and Acrobat. Works like an Apple GPU complete with boot screen.

Note - The specs for Apples 6800 is the same as my card except for the memory (16 vs 32GB)
Apple has nothing that match the specs of the 6800XT
The Apple 6900 card does match the specs of the 6900XT, again except for the added memory.

I ran dual 6900xt - was perfectly fine and stable in FCP and Resolve, fairly quiet too.
if I didn’t know what was in the Mac Pro, I would not be able to tell the difference between these GPUs and an mpx module.

Specifically for Final Cut Pro - do you think it will utilize 4 w6800x gpus from two infinity fabric linked duos?
usually fcp seems to cap at 2 gpus, unlike Resolve. I wonder if it will use the 4 with IF..

I don't see why Apple would sell the configuration if it didn't work.
