3 Quick Questions About AMD 5350

[Justinbaileyman]

Does this APU support 4K playback?? I tried a 2K video trailer and it worked perfect but when I tried the 4K version it started flickering and stuttering. I tried this on Ubuntu 14.04 64bit in VLC using the latest Catalyst 14.9. Would Windows be a better choice??Or does it not matter which OS is used??

 

[monstercameron]

no 4k playback and the cpu is too slow to decode 4k. I believe intel atom parts can support 4k.

Are you sure about this.?.
Not sure that Intel support 4K, Haswell Celerons have no support for it.

baytrail supports 4k video decode

baytrail supports 4k video decode

Possible but the question was about AM1 having support or not, i dont think that MB manufacturers would point this feature if it wasnt supported.

GIGABYTE AM1 series motherboards provide native 4K support with AM1 APU integrated graphics via HDMI port.

Besides a J1800 is at about Sempron 2650 level in this matter, i dont think that a J1900, wich hasnt exactly double the throughput of a J1800, would be better than a 5350 wich has 3x the throughput of a Sempron 2650.

Then why do many (all?) N2830 laptops, stutter playing back 720P and 1080P YouTube?

I couldn't even imagine trying to play back 4K on one of them. I doubt that their HDMI port even supports a 4K display.

MAYBE its done using QS

"Drive a UltraHD display" != 4K video decode, it does not say anywhere that indeed supports 4K decode.
Guru3D link says it cant too.

unless there is a limitation on the UVD engine it may be a driver issue or something to be added later.

4k video output and 4k video playback are 2 different things, kabini and beema can support 4k30 output. Also the athlon part maybe faster than baytrail doesnt mean they can stutter free decode 4k video[not even kaveri can do it, I've tried]

My z3740d doesnt stutter on youtube or hulu or crunchroll so I dont know your situation.

I havent tried it my self but some reviews tested 4K youtube video playback and it was fine. Perhaps it is a Linux problem or something else.

 

[ShintaiDK]

Only GCN 1.2 supports 4K hardware decode from AMD. And the only product with that is Tonga aka R9 285 and M295X.

 

[Techhog]

baytrail supports 4k video decode

What the heck? My i5-4210U crashes any video above 1080p!

Sounds like software issue. Because it supports 4K decode as well.

It s on the right of the slide, video player like Media player classic will use only CPU to decode, as you point it theses must be updated to take full advantage of the UVD.


ShintaiDK, GCN has nothing to do with video decode, there s a dedicated engine for this task.

 

[Justinbaileyman]

Well I have only used Ubuntu 14.04 64bit with VLC for testing 4K video's do you thinking Ubuntu is just not far along enough to support 4K yet?? Should I ditch Ubuntu and head back to windows?? I see windows 10 is free right now for like a 6 month trial,so that would be plenty of time till I am able to go out and purchase a retail or OEM version.
I am guessing here that windows will have better support for 4K?? Dont bite my head off guys I am just guessing and dont really know thats why I am asking the pro's..!!

Kaveri can decode H265, let alone H264...

Kaveri supports hardware decoding of H.264 and VC-1 video codec standards.

Kaveri will support h265/hevc as well. The new video codec is up and coming thanks to the rapid adoption of Ultra HD and thus the sheer need to preserve costly bandwith.

Seems that no one know exactly the situation, there s claims on slides and sites that say that there s support, i ll also give it a try though..

Well it kinda does. Since all the UVDs previous to GCN 1.2 is broken in relation to 4K.

First and foremost then, with GCN 1.2 comes a new version of AMD’s video decode block, the Unified Video Decoder. It has now been some time since UVD has received a significant upgrade, as outside of the addition of VC-1/WMV9 support it has remained relatively unchanged for a couple of GPU generations.

New to UVD (GCN 1.2) is full support for 4K H.264 video, up to level 5.2 (4Kp60). AMD had previously intended to support 4K up to level 5.1 (4Kp30) on the previous version of UVD, but that never panned out and AMD ultimately disabled that feature

 

[Shivansps]

H265 support on OpenCL by Kaveri has nothing to do with the UVD block, its a Hybrid CPU/OpenCL decoder, Intel plans to do the same thing as well.

As for 4K, if the driver and UVD block supports it, you need to check if the decoder is enabled to use it, for example i had nothing enabled in the LAV codec so CPU was used.

As for Bay Trail, i can confirm it.

At last to 30fps it works, 60fps is broken, it will lag terribly even trought it does not use more than 5% cpu.

i can assure you that h.264/5 1080p60 works but 4k playback is a no go.
yeah shintai got it right (what a strange day, shintai says something right )

Seems that few sites did test the thing, Xbit labs did but with MPC wich use mainly the CPU for decoding, Legitreviews did also a test although i have trouble understanding why a 4K video was rendered at 1080p.

How does the AMD Athlon 5350 APU do when it comes to Youtube video playback? The first 1080p clip we tried was Marvel’s Captain America: The Winter Soldier – Trailer 2 and we had around 22-35% CPU usage during the playback of that movie trailer.


The next clip we ran at 1080P was called WILDLIFE IN 4K (ULTRA HD) 60FPS and we found that the CPU was at 50% load.

Guru3D take on the thing :

We also tested Ultra HD video acceleration. Above the 4K resolution Elysium Trailer, here we have an MP4 H.264 file and you can see that the CPU load is 52% with one core topping out performance. Unfortunately Ultra HD videoplayback resulted into stuttering. For both content we have additional shaders enabled like image sharpening and darkened black levels.​

The reason why we noticed stuttering seems to be that the trailer is not DXVA encoded. meaning of you where to RAW decode video streams over the CPU, it would not be powerful enough. The GPU at DXVA will take care of you on that here though.​

I tried playing that back on this E1-2500 Kabini / Win8.1 64-bit / Waterfox 32.0.3 / newest Flash Player 64-bit plugin / 1600x900 screen, and YouTube auto-selected 720P for me, and if I had to guess, it was running around 8-10 FPS full-screen. It would pause briefly at times. Didn't seem like buffering, I have a 30Mbit internet connection.

 

[Abwx]

With a E1 2500 CPU load should be at...150% extrapolating from the 5350 s 50%, must admit that i didnt pay attention to 4K since it s not widespread.

my c-50 could handle 1080 flash but an update borked it in chrome and firefox, only IE works. v-larry can you try in IE?
