Hey there,

we are in need of a new GPU for our main editing workstation and it comes down to the two candidates mentioned in the title, the RTX 3090 and the RTX A6000.

Usually the RTX A6000 would be too much of a price increase but given the fact that the RTX 3090
(or any performance graphics card for that matter) is heavily overpriced right now, the difference isn`t as big as it used to be.

Performance wise the RTX 3090 should be faster than the RTX A6000 but there is the obvious argument that the A6000 offers double the amount of VRAM and at least in our case resolve seems most of the time constraint by the amount of VRAM our GPU can offer.

Where do you see the biggest benefits when going with a RTX A6000? Are there any other improvements with a quadro i am not taking into consideration? Are those cards for example specifically tested with resolve and therefor supported or even recommended or would you guys go with the RTX 3090 and save quite a few bucks?

Thank you in advance for your opinions.

Cheers
Dennis

Noone that can share his/her opinion here with me?

Ok

Since GeForce line has got 10 bit enabled in professional apps, there is really not much going for a Quadro. It's probably more like you get better support when you require it. Otherwise, no benefits, especially not in resolve, anyway. The "GPU memory full" error can occur on Nvidia GPUs with really lots of VRAM so it seems to be the issue of how VRAM is managed by the driver and not how much of it there is onboard.

I found that posting on Topaz Labs Video Enhance AI forum very helpful:

The part on power consumption, temperature, and throttling.

A6000 got a score of 1553 overall and 141 for GPU

3090 was 1560 and 155

So if your job will fit in 24gb, then it looks like the 3090 will be faster. Of course if you need more than 24gb, the 3090 won't work period.

I can say with my 16gb 3080 laptop, I can export 4k with NR and motion blur on 8k R5 footage with no issues.

The bigger issue is can you get them today if you want to? In the USA, they're pretty much out of stock.

I can't say I have looked, I wish I had that money, but I thought the stupid expensive cards stayed better in stock as no one would consider them for mining.

But it may be like with the other GPU's your only option for availability is via a prebuilt machine.

They are so expensive because of the demand for mining (plus general supply chain issues).

In October they started to be available here in Europe for a while at pre-shortage prices. Looks like it dried up again though.

Hackers have recently unlocked Nvidia's enhanced anti-mining measures which might have an effect on availability as well.

Hey there,

we decided to go for the Quadro card after all.
As we have a big project ahead of us, we didn`t wanna cheap out on the most crucial part in resolve, which is the GPU. Not to say the RTX 3090, is a "cheap part" in comparison by any means, but as the card is hard to get in my region anyways and the price difference to the A6000 is at least not as painful as it used to be, we went for it, as we need the hardware soon.

Thank you for all your feedback.

If the price is close enough in your market, no problem.
Faced with the market situation, I have ordered the Quadro T600 for my small form-factor support machine as it's of slightly better performance than similarly priced GTX models and power draw is next to nothing. And I get 10-bit h265 NVENC encoding.

Got the RTX A6000 now too.
While opening the box, I almost expected to find a bottle of expensive red wine in the package

Château Mort (Tatort) ?

If one of the A6000 owners can spare the time, could you try running the benchmark we tried in this thread?

viewtopic.php?f=21&t=150120&start=50#p804323

I will, but I have to build the computer first as I am still waiting for the Fractal Design big tower case delivery.

Jack, can you guide me to the exact posting with the benchmark?

Château Décadence

It's a very simple project, just using some typical and demanding functions or effects in DR.

The project is here: dropbox.com/s/9wf1tl92bd7qq ... p.zip?dl=0
The Clips are in BM's Gallery for the 12K under "James Perse - Robertson House" (but in 8K).

Finally I was able to render that test project as the first RTX A6000 had a dead fan on arrival and today I got the replacement card. One would think for that price PNY would have better quality control...

Anyway, Uli's project rendered in

05 m 19 s for DNxHR HD out
04 m 58 s for DNxHR UHD out

on my newly build PC:
AMD Ryzen 9 5900X 12 core / 128 GB DDR4 @ 3600 MHz
Gigabyte B550 Vision GP
PNY RTX A6000 / 48 GB <- ECC ... off

Win 10 Pro 21H1
Nvidia studio driver 472.47

Resolve 17.4.2

GPU was always at 99% load, CPU at around 5%, GPU VRAM used was 17 GB for HD and 22 GB for UHD

For UHD your numbers would have been nothing short of sensational

Well, the UHD output rendered even faster.

Please post the complete link.
Thanks

I don't understand this .. are the files used 12K or are they 8K?

They are 8K since some machines we wanted to compare choked at 12K.
These were the only ones at 8K in the 12K gallery and I wanted something that's accessible to everyone.

Renders in 4:44 on a 3090 with all kinds of stuff running in the background concurrently and slow ECC memory.

So except double the vRAM it seems like a waste of money for Resolve.

Not so sure if that's actually still true. At least from the task manager screenshot I posted it seems it's swapping to system RAM just fine using a total of 29GB to render the project.

Sadly another case here.

Yesterday I bought a BMPCC6K Pro and installed Davinci Resolve Studio 8.
Imagine the excitement. 30 minutes in and I am denoising my first clip. 31 minutes in my secondary 3090 Gigabyte OC Vision dies. Exactly as you describe. Loud fans spinning, screen going black. I managed to shut down the PC in time the first time. On the second time, the card died.

I am not an editor or expert in filming just passionate about this. I have been working in CGI for 20 years and thought to add a cinema camera to my arsenal. That excitement turned into expensive damage.

I run very GPU-intensive processes and there's no one software that ever produced a hardware fault.
The feeling I had is that Davinci was overriding the safety limits for the GPU.

Resolve can't "override the safety limits", it just uses the GPU driver.

Da Vinci cannot override computer (Bios,Drivers, Power settings) , this most likely a defective GPU card.

The 3090 is comically power hungry and produces massive spikes in transient load, which power supplies frequently can't cope with unless oversized for the build. I put a 1000W PSU in my build for safety and have never crashed from load issues.

This was -NOT- caused by Resolve. If you search around you will find number of 30xx card users experienced similar issue to yours, with cards dying in similar manner, when running software that puts heavy load on the card (typically games). Many have experienced that when running beta of Amazon's New World. Issue was not isolated to any particular software nor to any particular brand of the card, and it has been traced back to design of the cards. You can find great discussions about it in EVGA forums. If I were you I would contact Gigabyte for replacement under warranty, then sell Gigabyte and get model that has solid reputation in regards to this issues (if memory serves me well Asus Strix and certain models of EVGA should be good, check more on EVGA forums and around).
