NO! The i3 is a quad core chip! Historically quad core was only for i5's. In fact, this is the first generation that the i3 has ever been a true quad core chip. So, for example, if we were still using 7th gen intel terminology, this would be an "i5".
This i3 is clocked the same as the i3-8100 @ 3.6GHz a quick search would show:
Passmark of: 8095 and single thread rating of : 2103
The best quad core ever offered previously was the i7-3720QM.
Passmark of: 8123 and single thread rating of: 1817

https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-3720QM+@+2.60GHz&id=895
So you are at worst equal to the previous best processor ever offered and your single thread power would be 14.59% better.
For a base CPU, its pretty damn good.
