Yes, these are A53 cores which the RPi 3 used. The RPi 4 uses A72 cores, which are a lot faster. A53 are efficiency optimised cores and A72 are performance optimised cores.
The RPi has such a big community that I imagine performance and optimisation will quickly surpass other chips, eg. Rockchip RK3399 [1] (2xA72 and 4xA53) and will probably end up on par with an Amlogic S922x [2](4xA73 and 2xA53).

To get the full performance out of the RPi, you are going to need a beefy heatsink or it will thermal throttle very quickly.
