C2D faces issues with certain 4K YouTube clips, though it works for others.
I have a media PC running an i3-6100 with 8GB RAM and an SSD in a living room setting. It performs well overall, though it struggles with 4K YouTube videos. I use Windows 10 Pro and Chrome. I know the i3 can't decode video hardware, so it relies on software decoding and utilizes its cores. My newer i7 models have better integrated graphics and handle 4K at lower frame rates while idle. I see some 4K channels work fine—like Hardware Canucks or Linus—but others, such as Gamer Nexus, freeze completely when the CPU hits 100% load. I also noticed certain 4K streams that require lower resolutions to run smoothly. Those also stutter, but I can't adjust the resolution settings (unlike Gamer Nexus). I usually avoid those channels. My suspicion is that it depends on how the streamer encodes or records the content. When I keep the window small, CPU usage drops, suggesting it's about display settings rather than performance. Without hardware upgrades, what alternatives exist? One idea is that some 4K streams only run at 30fps, others at 60fps, and this variation explains why some work and others don't. Is there a way to force the slower frame rate? Another thought is that YouTube may automatically switch to lower resolutions after a short delay; it improved recently, so I might have missed a fix. I don’t see a method to set a specific resolution per stream. My other i3-3220 runs smoothly on an HD TV and won’t go 4K unless the display changes. If my TV upgrades to 4K in the future, performance could worsen further.
Youtube employs VP9 and AV1 for 4K content as far as I understand it... AV1 tends to be more challenging to decode in software, whereas VP9 is generally simpler. The decision might hinge on factors like channel popularity or how frequently the video is viewed—conversion to AV1 could influence that choice. Alternatively, it could simply be a random selection by YouTube. A clearer inquiry would be why you're drawn to such high-resolution videos? It seems unlikely GamersNexus uses a camera exceeding 1080p. Perhaps HDR considerations play a role if the video was uploaded in 10-bit color depth, though YouTube typically delivers standard SDR for broader compatibility.
I also feel this way. It seems the developers don’t alter their approach just for me. It looks like someone on YouTube or the creator made that choice about the codec, and it stays that way. I’m okay with watching all of YouTube in HD. TBH, if I want 4K content, starting with HD would be better since it automatically jumps to 4K but then stutters until it settles on HD. Beginning at HD should fix the issue. TBH, YouTube has definitely gotten better at handling the transition to HD over time. Not long ago they would always display the "test your network connection" warning when there were problems, which clearly wasn’t my situation. They’ve improved that, and now it seems they can handle it without me needing to worry.
AV1 saves space and data but requires more power during encoding. YT seems to rely on a method that estimates views, duration, and other factors to determine if encoding AV1 is worthwhile, leaving both creators and viewers with limited influence.
Adjusting it to HD appears to be the only option I can manage. Is there a method in YT to ensure a maximum resolution? If it can't be set by default, I might have to rely on switching quickly or hoping for improvements in their settings. To be honest, when I change Gamers Nexus to HD, I don’t notice any difference on a 60-inch TV. I see marketing reasons and the trend toward 4K, but for shows like this, 4K isn’t essential.
Are you wondering if your i7 is from the 11th generation or newer? Or perhaps you're curious about a new integrated graphics card inside? I know you're not looking to upgrade your hardware, but if you need to stream 4K AV1 content, here are some affordable choices: an Arc A380 Radeon RX6600 with RTX 3050, a mini PC with AV1 support.
I have two i7 processors: i7-6700 and i7-7700K. If possible, I prefer not to install a dedicated GPU. For the cost of an Arc380, I could purchase an AM4 MB and a 5600G. Choosing hardware means upgrading to a newer CPU or adding an integrated graphics solution. An iGPU appears to be the most energy-efficient option. I believe any modern CPU with an integrated graphics unit should handle YT formats natively or with software support. I also have some older GPU units from business computers that are slightly smaller and might work if I decide to try them out. They caused issues with overheating, but I’m open to testing. Thanks for suggesting the GPU idea!
