Why is Handbrake so slow?

[Gjwilly]

I changed from the 2014 rMBP with a 3.0Ghz i7 to the 2017 MBP with the 3.1Ghz i5.
Both have 16GB RAM.
Everything I've found says that these two processors (I7-4578U) (I5-7267U) should have similar performance. Same number of cores, same number of threads, and same frequency.
If anything the newer i5 should be the winner.
But encoding with Handbrake seems to take forever with the new MBP.
What am I missing?

It's hard to compare Handbrake's performance when you're dealing with different files all the time. Do you have a single file that can act as a benchmark?

Could be thermal throttling, Handbrake is a beast it will suck up all the system has to offer, in my experience for effective, as in fairly fast encoding you need tone dealing with a Quad Core i7 and or dGPU

If you have different versions of Handbrake on the different MBP's, the default settings may have changed. I did notice that in the latest version I installed, there was a default setting changed compared to an older version which made it slower (the preset "faster" to "fast").
