I think I know the answer already, but I can't find any benchmarks to confirm. Unless I just don't understand the benchmarks that I've seen - which is possible. Basically I'm trying to decide if the 4.2 i7 vs the 3.8 i5 will give me noticeable, time saving differences for my use. I've been doing more video editing and encoding lately. Lot's of time taking clips from friends and family from weekend trips, parties, backyard fun, etc. and mashing them into something watchable and catering to everyone's formatting needs. I probably mess with a few hours worth of video, editing and encoding, per week. I'm wondering if anyone can tell/show me what sort of time savings I could expect with the i7 over the i5. I know that can be vague, so maybe the following chart will help give you an idea of what I'm looking for. In their example the i7 was only only 11 seconds faster at the conversion. Since it was only a 6gb 4k file, I'm guessing it was only a 60 second clip or something small.

But if were talking maybe a minute or 2 tops, then it's not. I'm not looking for someone to give me an exact amount of time savings, I know that's not possible, I just want to know really if it's noticeable. I'm just guessing, but I'm guessing that hyperthreading of the i7 will be noticeable the longer and longer it goes. So while this small file didn't have much of a difference, when we're talking hours worth of video, the difference will start to be more and more noticeable, but I'm not sure.
