AMD vs Nvidia power draw? Is my power supply good?

[ChungKingCanSuckIt]

My system:

i7 11700kf
64GB DDR4
m.2 drives x 2
360mm AIO liquid cooler
Besides the keyboard, mouse, and headset, I have a joystick and 3 external hard drives plugged in

I have problems with Adobe Premiere.. they're telling me my video card isn't supported, so I have to buy a card.

If I'm comparing both brands with cards in similar performance area, which brand generally has less power draw and will my power supply be enough?

I kind of want to go AMD because it's cheaper.. I am looking at an RX 6700 XT.. they're under $400. I don't think I want to go any higher.

What is your power supply?

Also how many monitors do you run?

 

[SpellowHouse]

All video card manufacturers specify a minimum power supply that is recommended for the card, with the exception of cards that use so little you can use even the smallest power supply. Beyond that it's best to just search for a review of the particular card, which will give you an idea of the power it consumes. Having said that, most cards consume a pretty trivial amount for office work. It's only with games the power ramps up. But you can even download utilities that will limit the power they take, if you are concerned about cost per hour or your power supply.

The specs of a reference 6700XT suggest you will need a 650W PSU. You may be OK with a high quality 550w, but I am never going to suggest cheaping out on a PSU if you can possibly have the budget for it, especially the way things are going now.

Really? What video card do you have?

From the benches that I saw on puget, recent AMD cards seem to work surprisingly well in the tasks that are GPU accelerated, but NVIDIA do have an edge and in other workstation apps they tend to have better support and optimisations. I know there have been a lot of driver updates lately (for both), but the 3060 Ti seems to generally perform better than equivalently priced AMD cards, though it does have less VRAM than a 6700 XT.

Sorry, reading the original post, I left out the power supply. I had started typing it, but must have erased it. I see the G there.

I have a G.Skill 850 watt 80 plus gold.

Someone asked.. I run dual monitors and someone asked about my current GPU. Dual 27" 1080p monitors, one is 120hz. Video card is AMD RX 480 8GB. System runs perfectly fine right now except video encoding with Premiere.

 

[ICDP]

That PSU is fine for your needs.

I'd want to confirm this with some other reviews, or benches, but in the puget link I gave above:

"The chart above is not an official part of our Premiere Pro benchmark at the moment, but is a calculated score from the H.264 export tests. As we showed in our recent Premiere Pro 14.2 H.264/H.265 Hardware Encoding Performance article, the amount of speedup you can see by utilizing the recently added hardware encoding feature varies greatly depending on your source media and export settings. In this case, we are exporting 4K media to UHD H.264 40mbps, which, coincidentally, is where we saw the largest performance gains.

Here, NVIDIA tends to have a solid performance advantage, which results in even the lowest-end NVIDIA GPU we tested (the RTX 3060 Ti) out-performing the Radeon 6900 XT by a solid 15%. The performance difference is even larger if you compare it to the RTX 3080 which is just over 25% faster than the Radeon 6900 XT when exporting to H.264."

This. You should be absolutely fine with that PSU.

Just to check, does Premiere tell you what's wrong with the current GPU? I'm pretty sure the 480 is capable of doing HEVC encoding and decoding... unless Premiere is now looking for AV1 support, or just started to drop the 480 due to its age.

Had to dig around a fair bit, but on their website it appears that they only support RDNA and the Radeon VII, but if you have a Polaris based workstation card it's still supported

Don't know if that's just the gpu-accelerated part, or if it literally won't run.

I don't think it did.. the 480 is definitely able to encode. The first time I started up premiere I did a test in code on one of my old videos and it went smoothly. The next few times I tried it froze up. That is when I contacted Adobe support. If it were up to me I'd have been using black magic davinci resolve but my friend is paying for it. Even though resolve is free I was going to buy the $300 bundle which gives you one of those editing consoles as I have always wanted one of those.

Thanks for all the replies. I still may buy another power supply someday. I am curious if they make any with longer cables. Every power supply I have ever owned doesn't have cables long enough if you want to do nicer cable management hide the wires.

I did recently watch a YouTube video that says you shouldn't use wires from different manufacturers and even the same manufacturer or aftermarket.

Every time I've ever built a computer the power cord is a little too short to go under the motherboard and up the other hole and plug in.

You can get extension cables with an added bonus of looking even nicer: https://www.overclockers.co.uk/cases-and-modding/modding/sleeved-cables

As for power supply, at 850w you're already future proof, it'll handle any mid range card and maybe even a high end card with a sensible power draw.

If you're swapping cables from the PSU end, then it's a very bad idea (can fry your hardware), but from the device end it is usually alright to use an extension cable, though it does add additional resistance (and cable clutter) which is best avoided if you can. That said, tight or bent cables aren't a great idea either, so if it is a stretch I'd rather use the extension. You can usually find the cable lengths stated in the manufacturer specs, or in the early reviews.

I'm running an overclocked 12700kf, 32gb 4133 DDR4 (4x8gb sticks) 360 AIO, 6800xt strix with the AIO also overclocked on a 750w strix PSU and it hasn't even burped.

It was only some of the older inferior PSUs that couldn't take the rapid sag, and that is mostly a Ampere issue any way.


Am just about to upgrade my away rig with a 6700xt strix running a 3950x on a 650w EVGA supernova. It too is overclocked using PBO and has had a 2080ti on water running at over 2100mhz for over a year.

Nice. I had a good feeling my power supply was good, so it's from an older system. The motherboard was aging (about 7 years old) so I suspected it was the issue, but the power supply was fairly recent.

Well, I just all of the sudden "stepped" into some money. A class action lawsuit I kind of forgot I entered. I'm not going to get the 6900 xt, although I could if I wanted.. I think the 6800 XT is a better value.. I might even go for a 6700 XT and 2 new monitors.

At that point I would wait on the 7000 series to release, it's just a few more weeks (13th Dec). Even if it ends up costing more than your new budget, it would hopefully cause the 6000 series to drop in price.
