Will this spec be OK for 4K?

PostFri Sep 24, 2021 9:01 pm

I am putting a PC together for video editing for hd and4K
So far got to this spec

Asus PROART B550-CREATOR Motherboard
AMD Ryzen 9 5950X CPU, 16 Cores / 32 Threads, 3.4 - 4.9GHz
128GB of 4x 32GB Samsung 3200MHz DDR4 NON-ECC Memory
OS on 1TB Samsung 980 PRO M.2 PCIe Gen 4 Solid State Drive
Data on 2TB Samsung 970 EVO PLUS M.2 PCIe Solid State Drive
NVIDIA GeForce RTX 3080 Ti 12GB GDDR6X Graphics Card

Questions are will this handle 4K ok?
Have I made any glaring errors or omissions?

If you're spending this much money, I would get a 3090 and not a 3080 Ti. 24GB is much more future proof than 12GB VRAM. I would also use 3600MHz RAM.

I'm no build guru Chris, but that looks alright to me.
Am assuming you've considered the limited PCI slot availability tho (2 PCIe 4.0 ... 1x16 or 2x8) and that it's likely going to be enough for your needs for its lifetime? I noted on the mobo specs that the additional PCIe 3.0 x16 slot shares its bandwidth with the Thunderbolt ports (so you can use one or the other, but not both) and the 2 PCIe 3.0 x1 slots share bandwidth with the 2x M2 slots... probably not an issue if you're only looking to add a single graphics card and maybe also a Decklink card ... worth keeping in mind tho.
Graphics card wise, an RTX 3090 would certainly be a nice upgrade for the doubled VRAM it offers... but the 3080Ti is a heavy lifter and by the time its paltry 12GB VRAM becomes a limitation you'll probably be looking for a new machine or a next-gen graphics card anyway.
Not sure you need to worry about spending extra on 3600MHz RAM... its all about latency anyway and some 3600 RAM is slower than some 3200 RAM... and I suspect either way the real world difference is likely to be intangible ie a fractional percentage point. But if money's no object then faster is faster.
You could maybe consider a SATA SSD (single or RAID) for your OS and then use the M.2 NVMe storage for cache and data... or NVMe for OS and cache and use an internal SATA SSD RAID for data. Also maybe should be considering a regular internal HDD RAID for online archive/media libraries... or an external Thunderbolt one.

Spending other peoples money is easy tho ... as is, I'd say theres nothing inherently bad about the proposed config that should prevent you from working quite happily with 4K media.
Let's have a return to the glory days, when press releases for new versions included text like "...with over 300 new features and improvements that professional editors and colorists have asked for."

That setup is overkill for 4K, but you'll be good for 6K/8K timelines for sure.

SATA SSD aren't much if any cheaper than NVME. If you have the NVME slots I would fill them first.

Right now you're stuck getting what you can find. That can mean 3600 memory might be cheaper being in stock or it might not be.

4K is just the resolution. Some formats are much harder/easier to deal with. The Nvidia decode page will show you which formats it decodes on the card. Google Nvidia decode encode matrix

PSU? Size and quality. Don't skimp. A Seasonic Prime isn't cheap but you won't regret it.

Case? Both for airflow and ports. If you're thinking of using a number of internal drives in the future make sure they'll fit.

Cooler?

Many thanks to all for the responses.

I am currently shooting 1080p 50fps for most things. As I have cameras capable of 4K as well as the HD ones I wanted to future proof this for 4k. Also software (DVR) never gets smaller or need less resources...

This will be the last computer the company will be buying me so it will have to last a decade.

Trust me, this is a never-ending process. I think at best, you can only expect a computer to last about 4-5 years. Much beyond that, they start to fall apart, projects become vastly more complicated, operating systems become more stressful, software gets more demanding... nothing lasts for ever. As the great SF author Isaac Asimov put it: "entropy can't be reversed."

I know all that but as I am in my mid-60's (11/23 months from retirement age) it is the last computer the company will be buying me. In 5 years time when I am retired in my 70's I doubt I will be doing more complex projects. However you are correct computers do slow down over time.

Spoke with the builder ( http://www.chillblast.com ) and they are of the opinion that the 3200 is stable in the system however 3600 is on the edge and may not be as reliable. Besides with other latencies you will never notice the difference and therefore not worth the cost in $$$ or stability.

The other point was It's not just the VRAM in Graphics cards. The 3080TI will handle 4K easily and start to slow down on 8K. However despite having double the VRAM so will the 3090. Therefore the extra cost is not justified.

I normally shoot1080 50fps, (it only goes on-line or local TV) but I have 4K cameras, so I might want to do 4K in the future. This set up is solid for 4K plus a bit. I won't be going to 6 or 8K.

Memory clock has a very big effect on CPU performance on Zen 3, and the reduced latency has a very big effect on performance at maximum load. Look for discussions on the REDuser forum for details. The 3090 will slow down on 8K, but it will be able to do it. The 3080 Ti will not, and you will swiftly get the dreaded GPU memory error. You may not plan on working with anything but your 4K cameras and HD deliveries now, but ten years is a long time.

If in 10 years time, having been retired for most of it I will probably want a new computer but I doubt I will have any interest in going over 4K for news, documentary and fun projects for the small screen.
