Today is 12/7, supposedly we can order tomorrow. But I have yet to find a review, and can we order tomorrow 6am EST?

AMD has not lifted embargo of reviews yet? Looks like no one cares. But if we can get this card for $1000, it is definitely better than paying $1500 on ebay right?

OK, I give up.

My desktop is waiting for 3080 now. It is the 1st time I build a PC for past 10 years, so I don't have a spare card and can only use integrated GPU.

You gave up very quickly, exactly 2h after creating first post :) Not to mention, you gave up almost 14h before product launch, this must be some kind of a record as normally people are giving up on purchasing unobtanium some time after it 'launches' ;)
Amazing resilience and strong will to endure in this race to buy a GPU. My respect!

My 6900xt showed up today! and it works!

My questionable ideas have also worked (so far):
adding a PCIe expansion slot to my itx mainboard by sacrificing the wifi card
and running a 6900xt, Vega 56, and a 4790k off a 7 year old 650w* power supply

While I was able to eth mine with no problems on that power budget, to game & mine at the same time I had to turn power sliders to minimum**. This lost a 100 points off the 3dmark score ( 12200*** to 12100 ).


* totally recommended by everyone! I do not see how anything possibly could go wrong ... 210-GQ-0650-V1 ftw
** -50% on the vega, and -10% on the 6900
*** it is paired with a 4790k from 2014, delighted with what I have :)

lootbox!:

installed in a questionable manner:

1x wire to each card ... anyway that itx mainboard looks tiny in this considerably larger case

You might want to take a look at some data I compiled in another thread: https://forums.anandtech.com/thread...river-overhead-problem.2591624/#post-40460588

Although it doesn't include a 4790K, the 4770K is bottlenecking the 6900XT in the newest Assassin's Creed game and that's probably the case for other newer titles as well. Upgrading to a newer CPU would probably give you a 15% performance bump if that one game is a good indication of average performance.

I'd probably just suggest a new build at this point so you can leave the old one as a separate machine that can do its thing.

I agree with all of your conclusions.


However, I am not willing to spend more money on my computer at the moment*. It will likely have to wait until next year and perhaps the Ryzen 6000 series or discounted 5000 series. I want at least 12 cores, good memory, 2TB NVMe ssd, and new high wattage PS. That will likely cost more then the 6900.


*on the other hand according to the mining calculator that 6900xt makes $5.90 a day, so it should pay for itself in 169 days ...

Reviews will be out tomorrow. Current rumors suggest that supplies will be limited as has been the case for every new card launched this year, so yes it would be better if you could get the card for $1000, but most people should expect to pay $1500 on eBay. Quite frankly the reviews aren't going to matter since there are so few high-end GPUs available that this is guaranteed to sell out.

I agree reviews do not matter, but when will it be on sale? 6am EST? I still want to give a try though. Just don't want to pay for fleabay price.

I just assume reviews should be out today to prepare for lunch.

Speaking of which, @lightmanek do you feel like pushing your luck with the 6900XT as well? You seem to be quite lucky snagging these cards :D

Just in case if anyone manages to buy one, would love to see some real-world benchmarks

Reviews are up now. Here is one of them. SAM is really impressive in some titles.

I tried a bit this morning, zero luck ~ instantly gone (plus AMD site crash). AMD added some more processors to their store this morning also, had chance at 5900x, but never even saw the 6900xt much less getting it into a cart. Yields are clearly low with far less 6900 supply than 6800's, even with the extra month for AMD to build inventory.

I've only looked at a handful of reviews so far, but is it just me or does the lack of Infinity Cache overclocking appear to hold back the performance of Big Navi even when the core clocks are pushed 10% higher than stock? I feel like I'm seeing OC performance gain in the <5% range even though the core clocks are pushed beyond 2500 MHz when stock is like 2200 MHz.

I also tried 6am pacific time, no luck. Paper lunch?

Yes, RX6000 series was effectively a paper launch. Hopefully within a couple of months, supplies should improve. Rumors are that there may be some large shipments reaching retailers even by the end of this month.

No, I would go for it if it was priced at $750-$800 mark, but for $999 it is a no-go.
But I'm too interested how it's going to overclock and perform at different tasks once it land in hands of enthusiasts.

You are missing the crucial variable here - stock clock at which card is really running is not 2200MHz. By default my card can boost to 2400MHz+ and it is predominantly power limited. To be honest, performance scales really well with GPU clock when not power limited. For example, my card is set to 2727MHz GPU, but in 3DMark PortRoyale card can hit 2670MHz only with one camera angle, in a scene not longer than 3 seconds, where rest of the test GPU sits between 2360MHz and 2480MHz, constantly hitting 300W limit.
I really hope that in not too distant future someone will release BIOS'es or hacked drivers with Power Limit ideally in -/+ 50% range.

Gotcha, thanks for clearing up my misunderstanding. Well, good to know that hitting higher clocks ain't an issue with RDNA 2. Seems like the natural progression moving forward is to tweak the architecture for better efficiency and IPC since it already clocks so well.

How is the performance at 1440p? I wonder how it compares to 6800XT and 3080 there.
