    Can your PC handle 4K 60fps in YouTube? TEST IT!


    Hi, a lot of people ask what are the minimum requirements to handle 4K 60fps video playback, specially in YouTube and other online media sources, to check if their PC is good enough for a Home Theater PC (HTPC), or if it will instead lag and freeze. We are about to find out!

    Today, in 2019, a FullHD resolution is good enough to really enjoy a very high quality video, but the 4K resolution has been around for a while, and to make a PC "future proof", I think it's better to have something that can handle 4K resolutions easily.

    OK, 4K is the "future standard", but then, why the 60fps?
    Good question, same reason: it looks like 4K 60fps is the most demanding video quality you can ask for today, without going overkill. And I believe it's going to be that way for a while (many years). Sure, YouTube might end up adding 8K resolution in a few years, but, in my opinion, that's simply overkill.

    Now, the test. Online video decoding is handled mostly by your CPU, so it's the CPU the one that must be powerful. Your GPU can help if your browser or app has hardware acceleration, but keep in mind it's a CPU intensive task.

    What you are supposed to have before the test:

    1. Internet Speed: at least 50Mbps, if you have low internet speed the video could be freezing because your speed, not your hardware.
    2. A clean PC without malware or bloat ware: no apps consuming resources, no virus, malware crap, etc... if your PC is in poor condition, that could be the reason why it's not capable of playing back fluently the videos.
    3. Latest version of Chrome (version 77) or Firefox (version 69). We don't want to test this under old software or browser. Windows 10 x64 if possible.
    4. Your screen resolution also affects the performance. If you are using a 4K monitor and Windows is set to 4K resolution, your hardware will have to work harder. So, when you post the results, you must tell us what resolution you are working with in Windows settings.

    How to proceed?
    1. Open Chrome or Firefox, and go to this 4K 60fps video:
    YouTube
    2. Set the quality to 4K 60fps.
    3. Right-click on the video and click "stats for nerds"
    4. The second line Viewport/frames tells you if any frame was dropped, that means, if your hardware couldn't handle the video anymore and started to drop frames. If your hardware can handle 4K 60fps like a champion, you will see a 0 value over there during the whole video. If just 4-10 frames dropped, it is OK, but if you get like 100, 200 or 400 frames dropped, your hardware can't really handle it. Not all parts of the video are equal: the most demanding scenes are around 3:00 and around 4:40. That means that your hardware might handle the video OK (0 frames dropped) but when a demanding scene comes, it will freeze and start to drop frames. Is that a win or a fail?
    I'd say a fail, you don't want to watch a movie with some scenes frozen and laggy, do you?

    Post your results!

    Here's your template
    CPU:
    GPU:
    Screen resolution:
    OS:
    Browser:
    Frames dropped at 4K 60fps:

    - - - Updated - - -

    My results:

    CPU: i7-4700MQ (laptop)
    GPU: nVIDIA GT755M 2GB GDDR5
    Screen resolution: 1920x1080 (Full HD)
    OS: Windows 10 x64
    Browser: Firefox 69.0.1
    Frames dropped at 4K 60fps: about 1500 during the whole video

    ...which means, the video is completely fluid most of the time but it lags and freezes in demanding parts.

    Conclusion: not really capable of doing it, my laptop really lags at minute 3:00 and 4:40.

    Wow, with screenshots and all, you guys are awesome. I'm trying to find out the sweet spot in order to tell the hardware required to get nearly 0 frames dropped, but it's quite complicated since the screen resolution affects, and also you have to count CPU and GPU. If it works with an i5-6400 and a GTX 1060... Will it work with am i7-6700 and a GTX 1030? How can we sort that out?
    I don't know neither how much impact could the browser have, because in my notebook, Firefox works better than Chrome (yeah, I'm surprised, it's always the opposite what happens). I have more drops with Chrome than with Firefox, I mean.

    I would think that hardware should cope, I did notice that the network activity showed a max of 2.5Mb peak traffic, average of 800k, so as long as your internet connection and PC's network hardware can process around 2Mb per second you should be ok. It seems this peak speed is needed to keep the buffer full, if the buffer starts emptying you will see stutter.
    Just a side note, if you are watching 4k on a 4k monitor there is a lot more work demand on the GPU as it has to push around, what, 4 times the amount of pixels?
    Both of our results are 4k at 1920 x 1080 res, a lot less demanding on the GPU, but the streaming, decompressing etc of the video was handled ok.

    What are you guys counting FPS with. My CPU, GPU and RAM are hardly bothered at 2160p60 resolution but internet is barely 20Mbps capable so I can see loading circle every 15 seconds. This is in Firefox.

    If you right-click the video and choose stats for nerds it shows an fps count overlay on the video.
    The display is frames dropped out of total played, sorry, not fps as in a games fps...if that makes sense.

    Hmm...

    "Online video decoding is handled mostly by your CPU, so it's the CPU the one that must be powerful. Your GPU can help if your browser or app has hardware acceleration, but keep in mind it's a CPU intensive task."

    Actually, the GPU is the game changer. 4K video is nice, but sitting right in front of a display is a bit overkill if it is too expensive. Just like a good 4K television - distance is your friend.

    In my experience with this 4K video, it's yes and no...

    In my own system:
    CPU: i5-3350P
    Video: Radion HD 7800
    Mem: 16GB
    Monitor: BenQ 2,560 x 1,440

    Can your PC handle 4K 60fps in YouTube? TEST IT!-i5-3350p.jpg

    CPU temperature increased 33 --> 54 degree Celsius
    Radeon temperature increased 33 --> 45 degree Celsius

    Other system:
    CPU: i5-8400
    Video: Geforce GTX 1050
    Mem: 16 GB
    Monitor: Samsung UHD TV 3,840 x 2,160

    Can your PC handle 4K 60fps in YouTube? TEST IT!-i5-8400.jpg

    The CPU temperature increased from 29 --> to 36 degree Celsius.
    GTX temperature increased 44 --> 46 degree Celsius

    It seems that the CPU does impact the video performance, even if it is related to the CPUs age.

    Note about the the picture quality...

    Both system did a smooth playback. My system did hiccup on the 8K video, while the other had no issues with it.
    With the BenQ 32" PC monitor the 4K video image is sharper, than in the Samsung 40" TV. I contribute this to the DPI difference between the two.
