CPU-Z is basically just there to show what's running your phone. As in the processor, RAM, and other stuff. With the app, you can check the SoC (System On Chip) name, architecture, clock speed for each core ; System information : device brand & model, screen resolution, RAM, storage.; Battery information : level, status, temperature ; Sensors.
System Monitor is one of my favorite apps here. It's a great looking app that allows you to check the frequency at which the processor is running at, what apps are hogging RAM, and a ton of other things. If you're looking for the complete package, System Monitor is the one to get.
This is a pretty simple app, and the design hasn't been updated in quite a while. But it basically just shows you the speed at which the processor is running at. Including deep sleep. That's literally about all we have in this app, actually.
A pretty simple app here as well. Not the best looking app, but it does what it does, and does it well. Features include; Battery details including battery state, health, usage technology and more. CPU information including CPU usage and technology. Signal details, check your IMEI number, phone identifier and more… Network, you can check your IP configuration, MAC, access point…
CPU / RAM / DEVICE Identifier
This app literally just tells you what CPU you're running, how much RAM and what device it is. That's about all it does. So it is a pretty small app, which is expected.
CPU Spy Reborn
This is a bit more nicer version of CPU Spy, and it basically just goes and looks to see what speed your phone is running at. Which helps to see if you've got a wakelock or something like that.

With CPU Hog you can go ahead and find out what apps or processes are hogging all the processor speed and the RAM on your phone. "You can control the battery temperature threshold, in which CPU Hog starts to look for the hogging process.
Note that every device has its normal work temperature, and its important to set this temperature with accordance with your device behavior."
