Other than the increased & ECC RAM they are the same. AMD doesn't play the same games Nvidia does with their workstation cards (gimping FP64 on consumer cards).
If anything you guys should be mad you aren't getting CDNA, which is designed for compute (OpenCL/Metal) instead of RDNA (which isn't) for the price.
Very true - I found this out the brute force method by testing the dual 6900XT vs dual Vega ii, and found the 6900XT to generally be superior
 
As it should be, Vega's are CDNA cards (old tech) and the 6900's are RDNA2 (new tech). And there is no point for anyone to target CDNA cards when programming. RDNA2/3 is what to code for, and Apple should be optimizing Metal and other GPU related code for their own silicon and RDNA functions.
Vega is not CDNA, Vega is GCN....

Yeah I agree. I went for the W6800 Duo too - but what do you think of the single W6900x? I wonder how much those 20 CU will make in terms of real world performance.

Getting two of those is a bit spicy though, even if it's technically the fastest 2 GPU solution. In Resolve, maybe 2 W6800 Duo for a total of 4 GPUs may outperform 2 W6900x, possibly.

Yeah, it kind of annoys me when people become apologists for market segmentation. Don't get me wrong, if I was the CEO of AMD I would absolutely price workstation cards higher because the market is willing & able to pay, but they're not wildly different.

Yes that is going to be a good benchmark to check; not sure if Barefeats has the pocket book to do that though.

I went for the Duo because overall as a single slotted solution, it offers more of everything.
 
My bad. So it is even older tech.
Yeah. GCN was really good at compute but not so much for rasterization. RDNA/CDNA split the focus. So I understand Apple not using CDNA purely for rasterization (since it is missing all those bits), and I get that RDNA can do compute, it just seems like it isn't ideal for it. AMD probably would have been happy to add some of the raster bits back to CDNA for Apple (for a price of course).
 
I love an upgrade, but I've only had my Vega pro 8 months, after being forced to upgrade from the shoddy 5700x basically made my Mac unusable the entire time it was installed. This is quite a fast release, given the apple silicon is also coming...

Likely it will be similar to the 6900 XT performance vs the 6800, so it is better, but not twice the price better, for sure.
 
Macrumors forum posters: "See! that proves M1 is a failure!"

It's more like what's the point in updating graphic card features for a model Apple is about to abandon (after just releasing it not too long ago)? These won't work on the M1 machines and the new Mac Pro likely will look like a toilet or something based on Apple's previous Mac Pro with nothing but a flush lever accessible to the user. That's what Apple has become. These graphic card releases just shows what Apple could have been if they maintained an Intel line as well. Not everyone wants M1, believe it or not. Some of us want Windows 11 compatibility more than what will likely only be a temporary CPU speed advantage. Apple was just getting to the point where a Mac Mini could plug in an external graphics card and be a powerhouse gaming machine in Windows mode while a quality Mac as well and Apple flushed that down the toilet too. But M1! But M1! shouts the usual Apple flavored Kook-Aid drinkers who love Apple no matter what they do.... Disgusting.

I did not say you could. I was referencing that the cost of $5,600 would be justified for a dual w6900x not for just one.

I’m not understanding your math. You say $5600 is what 2 should cost. So 1 should cost half that - $2800. Yet all indications are that if you wanted to buy just one of these things it would cost at least $5000.

Bro. a retail 6900xt is $999. a retail w6900x is $6,000. $5,000 extra price tag does not justify the minor slight increase in performance and 32gb of vram. I am simply stating that for those prices we should have seen huge increases in performance.

You know the 6900xt is not the same thing as the w6900x, right? You can’t just take the chip from the 6900xt and stick it on a w6900x board and expect it to work. AMD charges a ****-ton for that chip for the w6900x. Way more than $999. And I’m not your “bro.”

Too many people think they’re pros when all what they really want is a higher-res Lara Croft bouncing along at 200 fps. I remember when a Super Mac Thunder II card cost $2999 and topped out at 1152x870.

We shall wait for real-world performance and benchmarks. From what I have seen from the benchmarks on w6800 that have already been released. I am not impressed.
 
People, these aren't gaming cards. While they share certain elements, they are different.

You don't pay Dodge Ram 1500 pickup prices to buy a new 18 wheeler, and you don't expect the Dodge Ram 1500 to do what the 18 wheeler does.

You MIGHT be able to get the Dodge Ram to haul 100,000 pounds or you MIGHT get it to last 2 million miles, but you will NOT get it to do both without extensive modification. By the same token, the 18 wheeler won't get the fuel economy, track performance, or the same user options as the Dodge Ram. Different tools. Different Jobs. Different markets. Different price points.

That's about how similar they are, even if you get them both with diesel engines.
You’d be lucky to get the ram to go for two million feet tbh.

Are you sure they aren't both Navi21 dies?

As someone who has tested the regular dual 6900 XT vs the Vega ii duo, the 6900 XT smashed it - so I doubt the W6900X, while being great with 32GB of VRAM, will be much better than the 6900xt. In fact, in some cases it will be slower due to the clock speeds.

I mean, $999 msrp vs $6000 is a HUGE delta. There's a lot of fluff priced in this one, I don't think it will reflect in the performance. It's even more than the W6800x Duo!

If a single W6800x is $2800, the W6900x should really have been close to $4000 tops, right below the $5000 W6800x Duo.

I mean, for less than 2x W6900x you can get 4 W6800 GPUs with two duos - that's a big gap imo.

I understand that they are "pro". What I just learned is that my "Radeon Pro 5700 xt" in my iMac is indeed clocked way slower that a standard RX5700XT (1500 vs. 1755 MHz). I do not know if the additional memory makes up for much.

I just assume this will be similar for those w6x00 cards. What exactly do I get as a pro apart from more memory?
