    4K Overclocking Benchmarks Run: No fps Gain in Video Games

    Edit: May-5, 2017 I asked if anyone has any 4K Gaming benchmarks, testing if Overclocking has any effect at 4K Gaming, eventually I decided to test it myself and publish the results for others.

    To make my story short: There is absolutely no benefit Overclocking your CPU if you use your PC for Gaming in 4K or Gaming in less than 4K with 60Hz Monitor/TV.
    As you will see the single lower result is in CPU based Physics benchmarks, even API Overhead test has almost identical results.
    The reason I decided to do it is because I got tired of heat, its hot 9 out of 12 months over here so getting "free" heating is unnecessary, also I bet that my Overclocked PC with 1080ti, WC kit, 4 HDDS and 4 SSDs electricity costs are not cheap either and for nothing since I only game from time to time.

    My Next benchmark run will be testing if there is any Performance degradation under Windows 10 Pro when running with Hyper-Threading Enabled.


    Test System:

    Mobo: Asus Sabertooth X99 (Newest Bios:3505)
    RAM: 32GB 2666Mhz Enabled through XMP
    GPU: Gigabyte Aorus GTX1080 Ti
    Games and Benchmarks Installed to separate SSD
    Windows 10 Pro Creators Update, Game Mode Off, High Performance Power Plan.
    Before running the tests I used Display Driver Uninstaller v17.0.6.4 to clean up nvidia drivers and installed Driver v378.92
    Display resolution and Benchmarks set at 3840x2160


    GPU overclocked during both benchmark runs: Power Limit: 135%, Temp:90, Core: +60, Mem: +400, FAN: Locked @ 100% (Found out that keeping fan at 100% locked allows for cooler GPU and less/almost no throttling)
    During benchmarking the GPU was locked at 2000Mhz most of the time, sometimes doing 2025Mhz and sometimes 1985Mhz



    Intel 5820K @ 4.5Ghz, Hyper-Threading:OFF, CPU Cache @ 45, C-Staes Off, all Power Efficiency features Off in Bios.

    VS

    Intel 5820K @ Default Clocks, Hyper-Threading:OFF, CPU Cache @ 31, Processor Integrated VR Efficiency Mode: ON, C-States up to Including C6: ON, ASUS EPU Power Saving Mode: On, Enhanced Turbo Boost: ON (I enabled this to get proper all core boost while gaming.)

    Fire Strike Ultra (Default 4K Test)

    5820K @ 4.5Ghz = Graphics: 7253, Physics: 12788, Combined: 3943
    Graphics Test 1: 41.99FPS, Graphics Test 2: 26.32FPS, Physics Test: 40.60FPS, Combined test: 18.34FPS

    5820K @ Default = Graphics: 7579, Physics: 1840, Combined: 1955
    Graphics Test 1: 42.91FPS , Graphics Test 2: 26.75FPS , Physics Test: 5.84FPS, Combined test: 9.10FPS



    API Overhead Feature Test (Default 4K Test)
    [​IMG]

    5820K @ 4.5Ghz = DirectX 11 single-thread: 1421011, DirectX 11 multi-thread: 1314870, DirectX 12: 6592312, Vulkan: 25879380
    5820K @ Default = DirectX 11 single-thread: 1344875, DirectX 11 multi-thread: 1128938, DirectX 12: 5713722, Vulkan: 24059458


    Edit:

    Based on these Benchmarks from Techpowerup, even at FHD and 2K, Modern CPUs no matter its speed or amount of cores (if you above 4) has no effect on game FPS.

    I'd say to try to get your overclock stable with SpeedStep enabled. Even with a GPU bottleneck at 4k, I'd bet you can still get a smoother experience with the CPU bumped up.

    You could go a bit further and set up a somewhat aggressive power plan in windows too. Power management is flexible enough that you can get the best of both worlds now.

    My chip jumps between 1.6 and 4.6 no problem. I'm pretty sure I could eek out a bit more framerate with the OC pegged at 4.6 but its not enough for me to abandon the power and heat savings.

    My CPU was OC to 4.5Ghz since day one, with dual 140mm radiator.
    The Heat is real :(

    Generally I would assume no.

    However that doesn't mean that in cpu intensive games at certain points there won't be slight slowdowns, I wouldn't generally say that it is useless 100% of the time.

    That's all what I would assume though, I can't give you any numbers or values out of experience.

    I tested it myself, see first post.
