It will work for some time.
I mean, it will be good for runnind DR on Linux, probably this enables you to ditch Windows.
Also prepare to get storage…
What are your current video works like?
I chose that RX6400 card for that reason… low power, only one fan, less noise.
I only ever use static graphics… no games or video.
It is adequate for my needs, but I have no idea how it will perform editing video.
I do some image editing, its color control is OK
My area of photography was still photography and I always prefer candid shots. But that I have left around 4 years ago. Nowadays, photographers born within 4 hours. They buy an expensive camera with a 300mm lens. Then they see sone YouTube videos and they know everything… at least they think so and I think, why on earth I did a year long course on photography?! I give my soul this consolation that at least I learned something. Photography as a subject is like an ocean. I have just collected a teaspoonful. Currently I take videos of my Golden Retriever who is my only son and I record his running, dancing, playing and making video from those footage. I am thinking of creating his own YouTube channel.
I didn’t know that!!! How??!! Please guide me. It will make my work much easier. I mainly work with PHP, CMS like WP (I cannot take the full name or Mullenweg will send me a court notice ) , Joomla, Drupal etc.) and MariaDB. In Windows, I use WAMP or XAMP and upgrading any component of XAMP / WAMP in Linux, well I am about to figure out. If you can give me a short tutorial on this, it would be very helpful.
I bought one from Amazon in 2022 - wasn’t Asus brand (can’t remember exact brand - might have been “Sapphire”) - was around $500 AUD - lot of money - most I’ve ever spent on a GPU. It was to replace an NVidia GTX1650 “Super” (2 GB VRAM). The main reason was I intended to run 3 displayport monitors in my Linux “rig” - it worked - but was bitterly disappointed that I couldn’t run a single Steam game across all three monitors (which was something I got working in 2013/14 with an NVidia 650Ti GPU and the game “Serious Sam 3”).
Anyway - the 1650 only had a single DP port - and I needed at least 2… and that’s what I’m using…
The ‘Linuxiac’ website is showing “Sorry, you have been blocked”!!!
I just clicked the link you gave, nothing else!!! Looks like the owner doesn’t like India and blocked our country by country code.
Btw, I have installed Apache and MariaDB in Mint. Now I have to learn how to use them.
Another thing, I am really confused about choosing a GPU. I searched the internet and found that AMD RX 6400 doesn’t have any video encoder. So video editing with this GPU is not possible. On the other hand, it is also mentioned that AMD RX 6000 series GPUs support AV1 codec. So I am super confused that if this card doesn’t have any video encoder, then how it will support AV1 codec??!! Please help me as I am in a tight budget and don’t want to use Nvidia in Linux. You know why.
I am using VPN in my mobile. May be that is why it blocked me. Many websites collect user data like country, city, ip etc. and when someone uses VPN, those websites block the user. May be they fill insecure because bad players can also hide behind VPN.
By today’s rate $500 AUD = INR 28,011.76 which is absolutely out of my range. So, after asking for help here, I was searching for a GPU with hardware encoding plus decoding which will not break my bank and I think I have found one… AMD RX 550 4GB DDR5. This is the least expensive card which is capable of 4k video editing.
See the image below:
Be careful to distinguish between the GPU and the card.
I may be wrong , but I thought the RX series cards all had the same GPU chip. … the differences between 6400 and 6600 beung other components on the card.
Am I wrong, lets check?
You are probably better off looking at the newer rx7600 series.
I actually tried to use my GPU for doing x265 encoding (resample e.g. x264 to x265 to save storage space on mp4 and mkv files) - and can’t remember the result - I think it didn’t seem to go any faster (or it didn’t work?)… I just use my CPU (Ryzen 7 3700X with 32 GB DDR4) now… and set the # threads for ffmpeg… Note - my CPU doesn’t have an APU - but my Mobo does support an AMD CPU with APU (i.e. built in GPU).
I actually meant the total graphics card by the word ‘GPU’. In reality the graphics processors are different in those cards. In the 6600, the graphics processor is Navi 23 XL and in 6400 it is Navi 24 XL and there are many more diferences. 6600 is superior than 6400 but the price is also more than double. But though the RX 550 is older and much cheaper (almost INR 3000 = $53.39 AUD or $35.70 USD cheaper) than 6400 and almost 3 times cheaper than 6600, it has video encoder and decoder embedded which supports h.265, 4k h.264 and hvec encoding and decoding.
In my thought, CPU rendering doesn’t always give better results and sometimes the system hangs up when using 100% of the CPU. I have seen that. That’s why I always prefer dedicated graphics card for graphics intensive works. But I may be wrong because I haven’t use Ryzen 7 processors.
My motherboard is older, Gigabyte 970A-DS3P. It neither supports APU nor it has an onboard graphics card. It is a pure full ATX motherboard and very powerful. A new system (Ryzen 5 3rd generation, Coolermaster Hyper 410R CPU cooler, B550 motherboard, 32GB DDR4 RAM, RX 550 graphics card and a Coolermaster 600 watt SMPS) will be very expensive for me right now. So, I just want to change my graphics card for the time being and when I will change the system, I will use this card in it.
Ability to display on 4K res monitor in native resolution doesn’t mean 4K video editing capabilities…
But honestly, forget 4K anyway.
Regarding RX550 I find the 2GB vRAM is way too undersized, it will be insufficient for Davinci very soon.
Can you afford an RX 560/70/80? They seem to have 4 to 8GB which sound much better, and their expectable performance seems to be much more Davinci-friendly, if you can afford, and DR is still of interest…
Unless you give it a high priority it does not hang.
Task scheduler in Linux is not the task scheduler in Windows.
I quickly demonstrate this for you.
Here on this video:
I open Gimp with a recent edit, export it to png with the highest compression available (that tooks the most processing). Look, how slow/fast it is done.
Then I start a conversion with ffmpeg using CPU only, an encoding to h265.
Then while ffmpeg is running, taking basically 100% CPU, I repeat the former action with GIMP.
Does it look like my system was hung during ffmpeg encoding eating up 100% CPU? Not to me…
And OBS recording was active meanwhile performing the test.
I’m not afraid of a task using (near) 100% of CPU, as long as it has normal priority, it won’t cause the system hang nor make it unresponsive.
This is not Windows
