The Sandy Bridge Core i7 3960X Benchmarked Against Today's Six-Core / 12 Thread AMD/Intel CPUs
There was also a great deal of difference in the web browsing performance. (Note: due to timing and Chrome auto-updates, the 3960X ended up being on Chrome 76 while Chrome 77 snuck into the other systems.)
Going into this I suspected the Ryzen 5 3600X would be a great deal faster, but hadn't expected it to be so dominating in a number of the tests.
