Do I need a dedicated GPU for 4k video viewing/streaming ?

Recommended Posts

Posted · Original PosterOP

The pc is going to be a media center in  a living room. Purely video streaming and movie viewing. It's for a senior man, so no gaming at all.

i3 9100, 16GB of RAM.

Do I need to buy a didicated gpu for 4k, or will the integrated gpu be sufficient?

Thank you.

No, the iGPU will be more than enough AFAIK.

That cpu is sufficient enough for 4k video playback, you don't need a dedicated gpu.

But in the future that might be a problem if the there's a requirements for heavier codec.

So instead of getting 9100, why not getting a Athlon 3000g or Ryzen 3200 which have a better iGpu.

And 16gb is a lot for only video consuming, 8 gb is enough.


Ryzen 2600 @ 4ghz | Radeon RX580 | 32gb HyperX 3200mhz | 500gb Samsung PM981a | 5 TB HDD | Corsair CX450

Yes and No.

 

For playback on a single screen the iGPU is capable of playback of 4Kp24 (eg film) or 4Kp30. If you do not have at least a Kaby Lake (7th generation) processor, then the capabilities are reduced.

 

https://software.intel.com/content/www/us/en/develop/articles/encode-and-decode-capabilities-for-7th-generation-intel-core-processors-and-newer.html

 

Note that VP9 (eg youtube) is decode only on the iGPU's. This is more than sufficient.

 

What will make or break a streaming box is if some future format comes down the pipe (eg AV1) and the fixed function decoder doesn't support it. As a direct example, HDR requires Ice Lake, and the upcoming Tiger Lake will support AV1. So I would probably pick an iGPU for now and use a dGPU later if something future comes down the pipe that requires more power.
