Agree, people see ‘10’ and think it must be better for all situations, I wish it were so simple. As has already been outlined, various applications rely greatly on clock speed as they’re yet to be optimized for multithreaded processing, and some processing requires a greater clock speed over more cores. An audio application such as Ableton Live benefits equally from clock speed and multithread processing, depending on how a session is routed. If someone is using heavily bussed channels with many plugins, clock speed is more important. If someone is using many independent channels more cores will be beneficial. Like you say, it’s not a binary situation because one is more expensive, but a fairly complex and nuanced one depending on the use case. I dare say for most cases the i9 will be better, but for some the i7 will be, or will be so close the difference is moot.
