Number of cores vs. speed

[freeradical]

I have a 2010 iMac with a quad core i7 with hyperthreading. It has a spinny drive and 12 GB RAM.

I have a 2015 MBP with a dual core i5 with hyperthreading. It has a SSD and 16 GB of RAM.

The Geekbench 4 score for multi core is 7050 on the MBP, and 8449 on the iMac.

In reality, when doing something processor intensive, the iMac is at least twice, and maybe even three times faster than the MBP.

Architecture baby, architecture...
