A few (1-2) 4k>1080p transcodes at once or multiple (5-7) 1080p>720p transcodes at once
@staknhalo thats cool, also links. thanks
just wondering ppl are using transodes in plex mostly for streaming to ipad/android … or whats the main point of transcoding in practice?
in case i want to stream 1080p->1080p then no gpu is needed?
Remember – in iOS / tvOS, the app is smarter. You get more DirectPlay so there’s less video transcode.
Same with Nvidia Shield except even better. Shield can DirectPlay everything.
It’s so good even an ARMv8 CPU can keep up with DirectPlay for multiple streams
what do u mean by DirectPlay - you also need network bandwidth… right?
then whats the point of the transcoding ?
Oh… now you have network restricftions? 
My point here is that iOS/tvOS/Shield will offload a lot from the CPU.
They are starting to get to the point of ‘balancing’.
I have 4k if in 4k and then only 4k so I use transcoding for HDR tonemapping to some devices non-HDR capable (my HDR capable devices can tonemap locally if need be) - and then for as you mention mobile device/out of home streaming for both me and people I share with - I only have 10 up and my 4K movies are on avg 45Mbps/45GB a movie I’m not trying to send that all out lol - but even when I only had 1080p my titles were on avg 15Mbps/15GB so I still was not trying to send all that out
I just looked at P400 vs P2200
Memory type GDDR5 GDDR5X
Maximum RAM amount 2 GB 5 GB
Memory bus width 64 Bit 160 Bit
Memory clock speed 4008 MHz 10008 MHz
Memory bandwidth 32.06 GB/s 200.2 GB/s
The limit here of 2GB RAM is going to get you.
4K with tone mapping is about 600-650 MB each. That gives you a memory cap of 3 transcodes.
means 3 simultaneous 4k tone mappings?th x
Yes that’s what fits in 2GB
I can’t speak to whether or not it has ample memory bandwidth but at 23.97 FPS, it should work.
I wouldn’t try 59.94 in it
well i am fine with 1-2 streams/ transcodes at the time.
can u use 59.94 fps?
thx
On the P2200, I can transcode multiple streams of Gemini Man (BluRay)
59.94 fps, 187 Mbps
(I bought the BluRay to use as a stress test video)
yes but is 59fps really possible to render on TV/projector etc?
Don’t know about projectors but in the US, normal broadcast television is 59.94 fps which matches A/C power frequency of 60 Hz (less vertical retrace blanking time from the old vacuum tube days)
why? 2gb ram is not enough?
i am still confused here … does it matter if u have 30 or 60fps?
Yes FPS does matter (of the source).
The doubled frame rate requires more processing on the card to get it all done in time without being jerky (similar to what’s seen in video games)
The 2GB of RAM isn’t the issue.
Look at the benchmark shown.
(I think I initially wrote of ram limit… it’s the processing limit… apologies )
yes but where do u render 60fps ? on 4k TV?
Most common (for me) is to render 59.94 fps on 1080p television; specifically a 2010 Vizio.
When I put the 47" Vizio and the 48" LG OLED side by side, I see:
- Crisper image
- Richer color HDR vs SDR
- Better saturation (OLED vs LED)
whats that? well but if u use projector/ ipad / laptop i dont think 60fps is possible?
well so that card p400 wont handle even 59.94 fps on 1080p tv?
I don’t know what the P400 will handle; I don’t own one nor do I know anyone who does.
According to the specs, the P400 will handle 1080p transcodes.
If I may be bold here.
You’re trying to figure out what works.
I know the GT-1050 Ti works for multiple HEVC HDR 4K streams – We use it in our Lab
Prices in Euros
The P2200 is twice the price or even higher if it’s even in stock/available.
Summary:
-
P400
– is questionable at 2160p with multiple streams -
GT-1050 ti
– is known to work at 2160p with multiple streams
– is a a reasonable price
– Can be mounted with the adapter you show. -
P2200 is known to work
– The favorite because it has more memory and more processors (more streams)
– Costs 2x as much
– can be mounted with the adapter you show.
Good GPU card acceleration is not cheap.
@ChuckPa thanks for sump up, makes sense.
just one more thing … i still dont get … that gt1050 is produced by multiple vendors as msi, gigabite … so does it also matter?
for example it can be used for 115euro
