    So, how much faster is a 2018 MBP with 2.8GHz Core i9 (32GB RAM) than a 2014 MBP with 2.8 GHz Intel Core i7 (16GB RAM) in editing 4K video files?

    How about other things like... editing photos in photoshop/lightroom etc..?

    Would the 2018 model be a LOT faster than the 2014 model? Would there be a considerable difference?

    Thank you very much in advance!

    I’m posting from mobile, so don’t have any benchmarks to hand, but I’m sure that the 2018 i9 would be a very significant upgrade.

    We’re talking at least 50% faster for video encodes, since they scale very well with CPU threads and clock speeds; the i9 (or both i7s in the 15-inch) have six cores with hyperthreading (vs four with HT), plus much higher boost clocks. Additionally, you’re comparing quite different architectures, so the 8th generation Intel chips will be significantly faster at the same clock speeds vs the 4th generation (I think?) from the 2014.

    Beyond the CPUs, the newer models have much faster storage and graphics, and the additional (faster) RAM will help in memory-dependent loads.

    It depends on the type of workload, but you can potentially see a big difference going from a high-end 2014 MacBook Pro to a high-end 2018.

    6 core vs 4 core, but under sustained loads it’ll throttle heavily. From what I recall, under sustained loads it was around 25% faster. In short bursts it would more than 25% I suspect

    Well when ever you add more RAM it will help performance. So just 32 vs 16 will be an increase.

    You are not going to find a 2018 2.8Ghz Core i9.

    But the 2018 2.9Ghz 6 Core i9 shows significant speeds over any MBP 2014/2015/2016/2017 model.

    Don't know much about video, but Lightroom is notorious inefficient. There are massive complaints about how poorly Adobe is handling the complaints about the performance. But that aside an i9 would always be faster than an i7, how much I do not know.

    I've actually been curious about this as well. Editing 4K footage on my base 2015 rMBP is pretty difficult and the playback is very choppy in FCX. I assume going from a base quad i7 with integrated graphics to something with dedicated would be a massive jump. I don't really care as much about the export times as the smoothness of the editiong process (which honestly seems way more important that the export times, never really understood the obsession with those times as you can just go do something else, but I do get that it adds up).
