Is there an app for checking what cpu is in your tab?

[opti]

Hi,

As the title says.
I can only find apps that show me the current / max speed of the cpu.

Also i found the following info: "cpu: ARMv7 Processor rev2 (v7l)

The tab I'm checking this for is advertised with a Cortex A8 1.4Ghz. All apps show me the max cpu speed as 1.2Ghz,
If I use some of these apps to overclock to 1.4 the tab instantly crashes.

Is there any app that shows if the cpu is an A7 or an A8? Or is there another way to check this?

Thanks in advance.
