How to check if my phone components are what they should be (is Dual-core 1 GHz Cortex-A9 equal to ARMv7 Processor rev 3)? I've bought LG Optimus L9 P760 - it came to me from China, without the foil and with unpacked charger. There was also no guarantee included (and I was assured there will be 24-moths written one). That's why I decided to check carefully everything else too.

It should have those parameters, according to specification:

Chipset              TI OMAP 4430
CPU                  Dual-core 1 GHz Cortex-A9
GPU                  PowerVR SGX540


But when I've installed the Android System Info application and exterminated the CPU:

Proccessor:          ARMv7 Processor rev 3 (v7l)
processor            0
BogoMIPS             1592.38
processor            1
BogoMIPS             1592.38
CPU implementer      0x41
CPU architecture     7
CPU variant          0x1
CPU part             0xc09
CPU revision         3
Hardware             LGE P760 board
Revision             0007
Serial               000000000000000
Frequency range:     300.0 -&gt; 1008.0MHz
Current Frequency:   800HMz


Is that the right CPU? Because I see ARMv7 Processor rev 3 instead of TI OMAP 4430 - but maybe those are 2 different things or some alias? Or maybe I've been ripped off by the seller? Is that possible?

System Info Droid also listed ARMv7 Processor rev 3 (v7l) and I cannot find Dual-core 1 GHz Cortex-A9* anywhere (however, I see that it's dual processor).

Also, under Memory:

Download Cache Max:     194MB
data Max:               2.33GB
External storage Max:   2.33GB
Total RAM:              767MB
Threshold RAM:          64.00MB


I see 767MB RAM, where there should be 1GB RAM. Is there something wrong, or some amount of RAM is not listed somehow?
According to Wikipedia,

The ARM Cortex-A9 MPCore is a 32-bit multicore processor providing up to 4 cache-coherent Cortex-A9 cores, each implementing the ARM v7 instruction set architecture.

(Emphasis mine)
Also, from the same article,

Chips
Several system on a chip (SoC) devices implement the Cortex-A9 core, including:

...
Texas Instruments OMAP4 processors (TI OMAP 4430)
...


And with help from eldarerathis's comment

The RAM difference is because apps will only report RAM that is available to userspace processes.
