YouTube primarily relies on CPU for processing tasks due to its current architecture and resource constraints.
Hello, I was checking 4K videos at 60FPS on YouTube to assess my computer's performance. I have a secondary monitor to track hardware activity. One observation is that when using Chrome and Firefox, YouTube primarily utilizes the CPU rather than the GPU. Is this typical? Others have reported similar experiences. According to a forum post, CPU usage is around 99% while GPU usage remains minimal (0-10%), not engaging. I’m not used to how hardware handles video playback, but could it be the GPU isn’t decoding the content? It seems inefficient if the GPU isn’t doing anything. I turned on hardware acceleration in Chrome, Firefox, and Internet Explorer. My PC specs match the details provided. FX-8350, R9 290. I also tested Internet Explorer, which uses 50-80% CPU but very little GPU usage (<10%). EDIT: I disabled hardware acceleration and noticed the performance dropped even more. 4K playback is still smooth overall. I’m using this as a reference example.
Yes, my GPU occasionally spikes to 50% for a brief moment before dropping back to 10% or zero. I suspect YouTube isn't causing this, it might be linked to my mouse cursor and the hardware monitor on the secondary screen. I've also tested fullscreen and non-fullscreen settings.
YouTube doesn't rely on your GPU for processing. These browsers typically don't utilize it.
It seems the system doesn't utilize my GPU, but it does engage a small portion of the CPU. Only about 8% of the CPU was used when running at full screen in 4K resolution.
