yes chrome as browser., and playback is quite choppy

will better gpu help?

That depends. What is your current GPU, OS, Browser (version)?

Not really, a better GPU isn't going to help you much if the CPU is being a bottleneck, some video streaming platforms are more CPU intensive and don't use that much GPU. Would consider upgrading your CPU if you are looking for better video playback, there are some streaming platforms which can take advantage of GPU decoding, although most tasks in your browser will be dependent significantly on your CPU.

 

Have you enabled hardware acceleration in your browser, if not try enabling hardware acceleration in your browser and see if that helps your playback performance?

I5-2500 does not have hardware decode support for modern Youtube videos (VP9 decoding), so it has to use "brute force". An AMD Polaris or newer (ie RX 480), or an NVIDIA Maxwell or newer (ie GTX 960) GPU will provide the hardware decode support that you lack.

sapphire 6850 1 gb, windows 10, lastest chrome i think

 

had got the gpu to run 4k 30fps  unnatively using quite some mods

Youtube does use VP9 when it can, which can be accelerated by supported GPU's. This will offload the CPU workload substantially.

 

This is exactly how cellphones play extremely 4K youtube, while having a much inferior processor than a 2500K.

Definitely you could improve the scenario by getting a GPU that can decode VP9 natively.

 

RX 400 series or newer (Polaris (GCN 4th gen), not GCN 1/2 gen arch.)

NVIDIA 900 series or newer (Maxwell, not Keplar arch.)

 

I include the arch, as some GPU's from those series (particularly low-end) use previous gen architectures, and do not support it.

The processor of a smartphone is based on a different instruction set architecture that a computer processor (ARM instead of x86 that computers would use) since less power consumption, less heat, fewer transistors needed, smaller die size, etc. Smartphones usually have some graphics accelerators, although it is much easier to drive a high-definition video on a small tablet/phone screen than it is to do that on a larger monitor/s or TV. For these reasons, you can't really compare the 2500K or other laptop/desktop CPU to a smartphone's processor in it's ability to playback video at a certain resolution (screen size varies and more pixels need to be controlled on larger displays, different processing architecture that is efficient for the workloads that it can run, although which are more limiting in terms of what software can be run, etc).

4k60 is still 4k60. That's the signal. The display size has no affect on how easy or hard that is to process, in fact it should be easier for larger displays, as they have their own processing for the signals to drive whichever technology they use. x86 and ARM can be compared by the results they produce: 4k60. Dedicated hardware to decode is what we are talking about, and that's included in more modern GPU's than the HD 6850, and is also included on the SoC's of smartphones.

This is only true if the aspect ratios of the displays are kept the same. If you are keeping the refresh rate, resolution, and aspect ratio consistent then it won't require more processing power for larger displays, although if you are watching from the same viewing distance then the picture quality will appear worse. Having a larger display does not necessarily mean that it will have its own processing for received signals if we are speaking of tablets/smartphones, for computer monitors that is controlled by drivers for your monitor which run off the connected computer (depends on the monitor but most modern digital monitors have their own processing for received video signals), and modern TVs mostly need to have their own processing to display signals since the possibility of being connected to display outputs which don't support decoding (an antenna for example).

i got  a rx570 into the same sys, cpu usage is still high, 60~80% in most 4k youtubes, 100% in gamernexus and lags....

[TheTechguy1]

Hey! I also have the i5 2500k but with a GTX 1060 6gb

I get stuttering and basically unplayable HDR 4k videos on YouTube, I enabled hardware acceleration on Microsoft edge, but my GPU is not being used at all and the CPU is at 100% 

 

What am I doing wrong?
