Few questions about ma35d
I thinking about buy one for home media server and streaming as hobby. But it's little too expensive for just buy and toying with it. I've done some reseach by my side but still there is few things I don't know or understand.
1. It support YUV420 / RGB Planar and 8 / 10 bit. H264 / H265 / AV1 on spec sheet.
Then is it support AV1-RGB-10bit?
And how about H265-RGB-10bit?
while every gpu encoding only support 4:2:0 on AV1 and H265/AV1 looks mainly YCbCr, I'm not sure it technically supported or not really.
2. Can it encode 120hz single stream?
Well, this one looks not possible on spec sheet but like GPU media core, might there is possibility to work 2 core together, perhaps?
3. How it works on high bitrate? Is it worth quality-wise?
I use custom streaming server for DotA event to broadcast in my local language,
and there's just 10-50 people watch it, so I put more bitrate to better quality. I understand that strengh of AV1 is high quality while low bitrate but like for 4k video 50%more bitrate than youtube, still has advantage? or focus on save bandwidth is the key?
Thanks for any help 😃

Let ask some clarifying questions
1. You're using this server to stream to 10-50 individual users? Is there a reason you can't use something like enhanced RTMP to encode the video once and then just send out those streams to the 10-50 people?
2. Do you NEED it to support 10bit for AV1 or HEVC? Why or why not?
3. Technically yes but I don't think even Addie tested that specifically. Is 120 necessary for DOTA?
I ask all these questions because you could theoretically get something like an RTX 4070ti or RX 9070 that can handle AV1, and then have that stream replicated through RTMP to multiple clients without re-encoding each single stream
You are right in every perpective.
It not really needed, not really effective in real situations.
Just mainly media server card + extra as hobby.
Main concern is should i use hevc4:4:4 10bit from gpu record for post edit or ma35d also can handle it by hevc or av1.
I'm sure I'll get 40 or 50 70ti for main card, thinking get extra in another slot is reduce some encoding steps.
Only reason I recommend the 4070ti and above is that it comes with 2 hardware encoder chips, where as the regular 4070 and below have only one encoder chip (at least for the 40 series)
5070 has 1 encoder, 5070ti and 5080 have 2, and the 5090 has 3
The main benefit (at least with OBS and FFmpeg) is that you can split the work of an encode across the encoder chips, letting you encoder higher resolutions and FPS at the same time
AMD doesn't have that but their AV1 quality and performance good regardless
Yea, I used secondary arc gpu as budget 2 media core for a while.
Point for now is, I might buy media card at some poont, but if those key above can achived with ma35d, I'd buy one soon.
But if not, buy it later like build home server lack later this year or next year.
And YES if you ask, server is also not really needed, just hobby. 😅
I search my archive once per year or 2. Just for 1 video.
The fact of the matter is that you're looking to get an $1800 USD card that has little to no support in most operating systems or software
Whereas you can get 99% of the functionality and quality for like $700 that will work with any OS and software
I use arch as main os, so os won't be matter.
Maybe only real matter for now is number 1 question.
It's might more like 'I want to record full color (4:4:4 or rgb), can I use ma35d for that? If I can't, I would use 4:4:4 hevc from gpu encoder.'
cause no 4:4:4 for av1 gpu encode now.
And also that's why I confuse, ma35d spec sheet looks little weird somehow.
RGB is not main color format for any of 264,265,av1.
