I was in the market for a new Mac to replace my mid-2010 27” iMac.
I ordered a mini days before the new iMac was released and then ordered a 2017 refurbished iMac but changed my mind and purchased a 2019 iMac.
I am keeping the 2019 and have returned the mini and 2017.
But, while I had all 3 machines, I did some benchmarking to compare them. I am not proficient with computers, just dangerous enough to wipe a machine clean by accident.
I timed the restart time and black-magic write speed of the 3 machines (also my current 2010).
Since I had some extra memory with both machines on my desk, I also added ram to the 2019 to see how the additional ram impacted the results.
See below for the results...
Note that the 2017 and mini where basically blank computers with just the operating system. The 2019, I transferred some of my data and set up a few accounts. This may be why the 2019 is slightly slower than the 2017. Or it could be the slightly lower speed of the processor as I believe the additional cores are better for complex operations but higher GHz for standard.
I decided on the 2019, mostly because for $250 I get a newer processor, slightly better graphics card and hopefully another year or two of updates to the operating system.
I know the RAM is not optimized because of the different speeds, and it looks like that when I installed the 2400 everything went down to 2400.
While I was at it, I did some speed tests with 2 external drives I have.
2TB usb a with spinning HD
1TB SSD connected via usb a and usb c.
USB C is about 12% faster than USB A.
SSD blows spinning HD out of the water.
Hope this helps anyone else trying to make a decision on what to purchase.
