Late 2012 i7 CPU vs Mid 2017 i5 CPU performance?

[jmpage2]

I currently have a late 2012 27" iMac with the i7 CPU. The machine performs well but is over 5 years old now and with the recent introduction of new models that meet my needs might be a good time to upgrade.

I primarily use the machine for light tasks but I do use it a bit for handbrake video encoding and am interested if anyone can share benchmarks on how the i7 CPU I have now would compare to the 3.8ghz i5 in the newer machine... specifically for multi-threaded CPU intensive tasks like video encode.

Thanks.

Heres benchmarks for the 3.5ghz i5, and honestly it performs very well! I do video editing and photo editing

Thanks for sharing this. I've been trying to find scores that would be directly comparable such as handbrake encode times, since that would be of the most interest to me.

I don't want my encode times to go up by dropping from the 8 threaded i7 to the i5, but I don't necessary need faster video encoding than I have with my current set up.... the faster GPU and 5K display along with other improvements would be worth the upgrade as long as CPU performance for intense tasks like video encoding didn't get any worse.

I keep wondering this too. I use Lightroom, Photoshop, and Bridge all at the same time and don't want any decrease in performance. Lightroom is my most intensive program when I export a batch of files, but I can also work in PS with documents that have 20-30 (or more) layers.

From what I'm seeing in other threads/benchmarks the i7 is about 35% faster than the i5 in video encoding on the 2017 iMacs. Probably for the $200 I would be stupid not to get the i7 again, just like I did last time so that's probably what I'll do.

SSD too.... because spinning drives are so last decade.

When it comes time to sell the used iMac, an i7 with adequate memory always seems to go much faster and for more money bhan an i5..

I will only know when I try to sell my i7 2012 iMac!

I will likely go with the i7 and an ssd to keep heat down and performance up.
