Anything wrong with 14900K? I choose 14900K because the price difference between 13900K and 14900K is just less than 10 dollars. I choose the processor because I intend to do 4k video editing and it should have enough power to do the heavy lifting together with the 4070Ti.
Please kindly advise otherwise thanks.
Well, it isn't the issue with $10.
There has been a lot of misconception that doing 4k video editing means going for the highest-end CPU.
That is actually far from the truth because most benchmarks for video editing are intentionally designed to NOT fully take advantage of hardware acceleration, which means at some parts of the tests, all the load will be placed on the CPU, and this is solely for the purpose of the test.
In reality, video editors will configure their environment to fully take advantage of GPU acceleration unless the software or codec they are using does not support it. A 4000 series GPU you are using would have most of your ground covered in terms of codecs supported, and the iGPU has some as well.
Modern video editing software often supports hardware acceleration through GPUs by using technologies like NVENC. This allows the GPU to handle specific tasks related to video processing, such as rendering effects, transitions, and encoding way more EFFICIENTLY than relying on the CPU alone which SIGNIFICANTLY frees up the CPU.
The difference in responsiveness is also very obvious during editing with GPU acceleration enabled. That's why even if you have the most powerful CPU, you still want the GPU to do it whenever possible.
Lastly, like other applications, video editing applications also favour p-cores. The intel 13700k has the same amount of p-cores as 13900k/14900k, so you are actually facing diminishing returns from this point on.
In conclusion, if you're experiencing stutters and lags during video editing, the underlying issue likely lies in the underutilization of GPU acceleration. Therefore, upgrading from a 13700k to a 14900k won't significantly improve the situation. If you're working with a large 4K60 clip, your primary concern should not be the CPU, assuming it's already decent, but whether the software and codec you're using support GPU acceleration and whether your GPU acceleration supports the codec.
