What To Upgrade Next? CPU vs GPU

PostSat Sep 17, 2022 1:39 am

I'm starting to do more 4K editing and rendering in Davinci Studio and would love a hardware recommendation for my machine.

Current Specs:
AMD Ryzen 5 3600 6-core, 12 thread
Two - RX 580 8GB GPUs
32 GB RAM
970 EVO 500 GB NVMe SSD
650W PSU


Cheers

The answer is always GPU. Go for a 6800XT if you can afford it. Hands down the best value / performance. 6900XT is overpriced and below 6700XT are not really worth it imho.

Then there's nvidia but there if you don't go with a 3090 and such it doesn't really compare.
Especially if you like not getting gpu memory full errors like you currently don't have (RX580)

Then if you work with RAW footage like RED RAW or CinemaDNG -> CPU power and more cores to feed the GPU.You can plop a 5950X on your current motherboard and be good to go for a long time.

So, it depends on what type of material you work with.

That 3600 is still good.

Thanks for the tips!

I was looking at the RTX 3060 and RTX 3060ti before your post.

I feel like it would make since to take whatever new card I buy into slot 1 and have the other RX 580s running in addition right?

Next Nvidia RTX4xxx series will probably be anounced in Nvidia GTC 2022. Nvidia CEO will talk in 20 September.

Your better off selling the AMD cards. Mixing brands is not a good idea.

Selling the two RX580 and moving to a single 3060 will not gain him any significant improvement.
3060s are terrible cards. Extremely overpriced for what they offer. Waste of money.

Except the 3080 12gb and 3090, nvidias lineup is terrible. RAM wise horrible.

Good info. The RX 6800 seems reasonably priced at the moment. Would this one stack better with my RX 580s?

How things work in Resolve, if you put all three cards those will work like 3 x 580 (basically the lowest card x 3). Combine this with the low PCIe lanes on the desktop AM4 platform, those won't all work @ 16X so you'll lose performance.(Not even sure depending on your motherboard if you can even make all 3 run) Also RAM doesn't stack so you'll be limited to 8GB. (assuming your 580s are the 8GB version).

You're better off with 1 powerful card, not 3. RX580 is around 6TFLOPS (2x theoretically 12 but its less than that). 6800 is a 16TFLOPs card with 16GB. No comparison.

6800 is an insane value / performance but they're like an unicorn. I think AMD stopped making those and focused on 6700XT instead. If you could find one at a reasonable price, I'd grab it.

Also you'll need studio to leverage the h264/265 decoders.

If you still want to go nvidia, unless budget is really tight, I wouldn't go with the 3060 class. Wait for 3080 12GB to drop in price. Or the 3080ti 3090 3090ti...My 2 cents.

Thanks for the info on stacking! Sounds like a single 6800 is a safe bet like you said.

They have them on amazon for about $600 right now:

That's the 6800XT. Its a higher class than the 6800. Its much better. 6800 non XT is a unicorn.

3000 series and AMD 6000series RDNA2 should get even cheaper. If you can afford to wait for the launch...wait. RDNA3 should also bring a lot of compute power if they go chiplets like the rumors suggest.

Awesome thank yall for the help! I can wait for the launch for sure.... I'll keep my eye on the 6800 XT price.

From a power consumption perspective. Will one 6800XT consume less than my two RX580s when rendering?

It consumes about 300W-ish. Two 580 consume about 360-400W. However, with newer cards, especially with the 3000 nvidia series (but not limited to nvidia) they have what's called transient spikes. These are usually up to twice the amount the card normally sips under load for very short amounts of time.

And these can trip your PSU. 650W is on the low side. Should work with a single 6800XT but don't quote me on it.

Did you get that graph directly from Puget Systems? It appears to be out of date. Their current Resolve hardware recommendations are here: Hardware Recommendations for DaVinci Resolve. That page is a goldmine of battle-tested recommendations for Resolve hardware on a PC.

You'll note that only one AMD card is on the current list. I'm neither an Nvidia nor an AMD cheerleader, but whatever you get note that Puget recommend that 8GB VRAM is the minimum required for 4K. Personally, I'd go much higher to avoid problems. Blackmagic don't publish hard and fast rules about what is a safe minimum amount of VRAM for a given timeline resolution, but they do admit to switching off various GPU acceleration features when VRAM gets tight [source here].

And given the amount of Nvidia "out of memory" posts on here, you can be sure that more VRAM is always better, especially with Nvidia.

Puget "testing" is pretty garbage. There isn't a constant in none of their "versus". Testing systems with DDR5 vs DDR4, 32GB vs 64...and so on. Testing files that are like 12seconds long...

Intel CPUs will start to throttle under long renders where a Ryzen 5950X will win vs a 12900KS for example.

They are using 3200CL22 for all AMD systems when they should clearly know that AMD uses infinity fabric to power their chiplet cpus and that is memory sensitive while Intels are not. Why CL22 and not CL14/16 like any normal human being would use on those systems only they know.

"Intel definitely still holds an edge in DaVinci Resolve compared to AMD's Ryzen line, but the Core i9 12900KS doesn't do much to expand on it.". Since when? Before the KS when did Intel have a CPU that was anywhere close to the 5950X...But I digress...

They also mainly push what they sell, which is Nvidia. Which is fine if that's your thing.

I wouldn't base my purchase on their "tests" though. A 6900XT is definitely not slower than a 3060Ti/3070/3080 no matter what they say. A Radeon VII (which for some reason disappeared from their tests is hilariously faster than a 2080Ti when working with RAW and NR).

And when you have graphs with scores that are like 1220 and 1230 it should raise a red flag to anyone. Means the tests is kinda meaningless...Its like when people test GPUs with premiere in non gpu accelerated tasks and go "a 3090 is as fast as a 1060 in premiere"...

Who to trust? An independent company who:
  • freely publish a Resolve test suite
  • regularly test all manner of hardware in large numbers
  • freely publish detailed test results
Or your opinion based mainly on brand loyalty. I bet you've even got the AMD mountain bike:

I gave you my reasons above...How is my opinion based on brand loyalty? Just because I have an AMD system at this moment? I buy whatever works best. That was the point of my post above.

Also define "independent company". They SELL you stuff. Its normal to push on to you whatever they want to sell. Its hilarious that you don't read between the lines.

Also what does that video have to do with our discussion? Feeling a little insecure or something? Are you a Puget employee that you feel threatened by my post?

Not a Puget employee, shareholder, nor have I ever bought any of their stuff. I just happen to believe they are at least as honest as anyone else out there. You obviously disagree. The AMD bike dig was uncalled for - I apologise for that.

But why are you thinking this? For me personally when I see a test where a bunch of CPUs do
90.18fps 91.02 fps 90.06 fps in some test and they tell you the .18 one is the best ...that's insanity...It clearly signals me that their test doesn't scale with anything. How do they even measure .02 fps?

Here's the benchmark I was talking about in my earlier post.

https://www.pugetsystems.com/pic_disp.p ... &width=800

Here the Radeon VII is faster than 2080Ti.

https://www.pugetsystems.com/pic_disp.php?id=53796 (just look at the NR results...)

In the posts above a 6900XT is much slower than a 2080Ti. That's a 2 generation flagship difference.
If you call this honest...I don't know what to think.

AMD cards don't show up in their graphs because they don't sell them. That's why I personally think no one should base their purchasing decisions for AMD parts based on Puget.

Maybe people like their customer service. The computer they build are probably fine. But again, I personally would stay away from anyone that builds computers in 2022 with CL22 memory. Especially with AMD cpus.

If you can direct me to a better resource out there who do large scale independent Resolve-specific tests on GPUs and CPUs then I'm all ears. I think this is my last word on the subject here as we clearly have very little we can agree on.

I'm sorry but I'm not here to guide anyone to "better resources". I really don't have time for that.
I shared my experience. I shared a technical reason why I think their test sucks. You haven't said anything to even change that other than "I trust them I don't trust you random guy on the internet". That's ok, you don't have to agree with me. I'm just curious to why you think everything I said above is wrong. I'm always eager to learn stuff.

And regarding better resources, you could always use google: https://www.richardlackey.com/best-gpu- ... vidia-amd/

Igor's Lab is also a good resource.

The Lift Gamma Gain Resolve Candle Test is even better.

https://www.pugetsystems.com/labs/artic ... olveStudio



Its not faster. How can you even take that test seriously? 3060ti is faster than 3070? Really?
Also why doesn't anyone who keeps bringing Puget here read the graph for the individual tests. I mean seriously no one questions these?

RED 4K to h264 has the 3060Ti beat the 3070 3080 and 3090. 73fps vs 59 for a 3090.
8K media score : 210 vs 207 for the 3090...

And many more : https://www.pugetsystems.com/pic_disp.php?id=66142
Come on...

It is faster than one 580, not sure if its faster than 2 of them in Resolve. FP32 wise they're about equal.

Apology to the FT for riding on this thread.

I am undecided on RTX 4060 vs RX 6950 from DR's CUDA requirement. Is GPUFORT in AMD now comparable with Nvidia CUDA for DR?

Thanks.

Doubt anyone here can answer that for you regarding GPUFORT.
One can only hope DR will implement HIP at some point instead of OpenCL.
HIP is great in Blender.

If you need debayer power...RX6950. If you need to develop for CUDA then go for a 3060.

I looked at the comparison between the 3060ti and 6800XT on userbenchmark.com and it does have the 6800XT winning... however I feel like that site's testing is geared towards video game performance... I don't know enough to know if that differs greatly from video editing performance.

I will say the 3060ti is alluring due to the price point of $450 vs the $580 6800xt :lol:

Userbenchmark is a joke of a site. They are banned in all reddit forums r/amd r/nvidia r/intel...That should tell you all you need to know about that site:


The thing that differs in video editing (Resolve) is compute power and / or hardware decoders.

6800XT is a better compute card than a 3060Ti. There's no doubt about that. It also has H264/H265 decoders (albeit maybe not as good as nvidia) but they're there...16GB of VRAM vs 8...No GPU memory full errors either.

3060Ti has better h264 encoder for low bitrates (nvenc). H265 high bitrate AMD is superior.

None of them have H265 4:2:2 decoders.

So depending on your footage, pick your poison.

Or if you think the puget benchmarks (where they have a 3060 beating a 3090 in 8K...) are great...go with that.

And if you want Nvidia, at least go for a 3080 12GB (not the 10GB one). Not a 3060Ti...

Many videos against Nvidia 4000 series now. Though Nvidia has the CUDA advantage, I am considering moving to AMD if its performance is comparable at the same model level (price, performance, etc).

Here is the Official Blender benchmark. Erase option Optix( Optix give a great advantage to Nvidias and i am not sure there is something equivalent in Resolve) Let only CUDA and HIP and click Search.

https://opendata.blender.org/benchmarks ... sion=3.3.0

Note there are a very limited number of Nvidias in CUDA since pretty much anyone now uses Optix. So the sample is not ideal.

Maybe OP may ask someone here with a 3060 and also a 6800 to make a test. I have only 3060 6Gb 130w laptop so i am not an ideal person to do it.

HIP-RT should be implemented in Blender 3.5 I think. That would give AMD the equivalent of Optix.

The way the prices are and them including the 3000 series as the budget option in their 4000 series presentation you'll be waiting a while for that 4060.

It sure looked to me there's a lot of unsold 3000 series that they need to move. That and the 4080 12GB that looks like a 4070 in disguise.

So in layman's terms does this sum it up?

"While the AMD cards may have more horse power; NVIDIA's implementation of CUDA allows less powerful cards to out perform for 4K video rendering. Thus the "weaker" 3060ti will likely outperform the 6800XT in Davinci Resolve."

Then

"The AMD 6800XT (12gb) will likely out perform the 3060ti (8gb) when it comes to vram intensive activities like 8K rendering"

No, has nothing to do with CUDA. AMD gpus are using both OpenCL and Metal on Apple systems which are 2 different things as is CUDA. For how Resolve works they're basically the same. All leverage FP32 compute to do various tasks.

A 3060ti doesn't outperform a 6800, even less a 6800XT. Only way it outperforms it might be when using nvenc which might be faster. For RAW and other things nope.

Even your second quote is supporting this, as 4K and above is VRAM intensive. And AMD memory management is much better. You wont get GPU memory errors.

FP32 compute and memory bandwidth (and quantity) is all that matters.

As an example, working with 4.6K CinemaDNG and 4K DCI BRAW on the same timeline, GPU uses about 14.6GB of VRAM...

Congrats on having a worse 1080ti for almost the same money 5 years later...Truly price / performance exceptional!

I stand by what I wrote above. Just like with the new 4090 being a good investment, the 4080 12GB is an atrocious value and it only exists to push 3000 series sales.

Interesting, thanks. I was trying to encompass why the 3060ti beats the 6800XT on some 3rd party tests... I feel like I need to get both of these and run a test render to really answer the question....

It depends on the workload. In Resolve, maybe in nvenc. In stuff like Blender and 3D rendering, it beats the AMD cards because they use OptiX for ray tracing which AMD doesn't currently have.

All should change when HIP-RT will be implemented. But software adoption is slow, AMD has much lower marketshare. And every one got used on using CUDA since its somewhat a plug and play thing, vs OpenCL where you actually have to optimize. Kinda got used to the "it just works" crap mentality Jensen Huang pushed for years. Doesn't matter if it works worse...Coders are lazy...

New ones are still over $900.

Same CUDA cores, smaller bus, more VRAM, faster clocks...less than half the price.

If I may just interject a little advice regards timing of your purchase of a new GPU as quite a few things are about to take chunks out of the price of any existing cards and maybe make waiting a couple of months worth doing.

1. NVidia is getting slated for its 40 series launch and only has the high end units on sale at time of writing. They also have a lot of 30 series stock still to sell so they're waiting to release more modest GPUs in the 40 series lineup (or at least that's the suggestion from more knowledgeable hardware nerds than me).

2. AMD are about to launch their new CPU and then GPU lineup and it's already purported to be quite eye opening in terms of performance (at least for the CPU's so far).

3. The cyrpto changeover for Etherium from mining to ownership has (so far) made mining uneconomical so the expectation is for a lot of used GPU's to hit the market.

So, even if the GPU's are the NVidia killers that some think/hope/pray it might be, the knock on effect of all the above factors plus better supply chain performance, post Covid should mean cheaper GPU's and possibly better bang for buck releases too...

Short version is that I'm kicking myself for upgrading my PC's 8 months ago... but hey, my 6700XT and 5900X combo is working quite nicely so I'm not complaining too much. Anyway, hope that's some useful food for thought.

So what? Makes absolutely no difference. Every improvement I've seen (including the new RTX4000 series presentation where the 4090 was 70% better than a 3090ti in "Ai") comes from extra CUDA cores. 70% more CUDA cores --> 70% more performance.

As far as I know Resolve is FP32...and the tensor cores are ...NOT.

Since Etherium mining ended...there aren't 900...You can get 3090s for 800usd...
Also 1080ti was 699...I wouldn't call 400 less than half the price...
