    I am planning a new build, and shopping for CPUs. I will be using my computer for general office work and video editing (non-professional), no gaming. I am brand new to video editing.

    I’ve narrowed my choices down to a Ryzen 2700X (3.7 GHz base, 4.3 GHz max boost) or a Ryzen 2700 (3.2 GHz base, 4.1 GHz max boost). Both are 8-core, and they both have similar max boost speeds.

    I was wondering how the CPU rated boost speed relates to video editing? Do certain operations in video editing utilize the CPU max boost speed? If so, which operations, and will I notice much difference between a 4.1 GHz and a 4.3 GHz max boost speed? Also, will I notice much difference in video editing between a 3.2 GHz and 3.7 GHz base clock?

    Thanks.

    For video editing, IF you're not overclocking, you definitely want the 2700X for its higher boost clocks.

    It's rare to see, if at all, base clocks on any modern CPU unless your cooling is extremely inadequate which would cause thermal throttling, and/or your video editing in the middle of Death Valley at high noon.

    In addition to that, it is extremely rare to see, if at all, the CPU's maximum boost speed unless the program that you're running utilizes only a single CPU core. But all recent video editing programs utilize all available cores, so you'll see less than the maximum boost speed. In fact, there are a few CPUs whose maximum all-core clock speed IS their base clock speed.

    This is true for instance, Pentiums and i3's since they have no turbo bins.

    The difference between the 2700 X and the 2700 is only 200 MGHz at the boost max. The difference at the base is 500 MGHz

    Will I notice either difference when video editing?

    Fyi, a 2700X will run at 4Ghz with all 16 threads loaded on the included Wraith Prism cooler.

    I mean, it's only a $30 difference....

    If you have a Microcenter within driving distance, you can get the 2700X for $280.

    Thanks. I guess I'm thinking that if there's not much actual difference between the 2700 X and the 2700, then I'd rather get the 2700, which is only 65W compared to 105W.

    That's why I'm interested in the differences, so that I can decide if the differences are worth it.
