My RPi 3 Gives wrong Info or Not?

[AlwinHummels]

I have a strange issue, yesterday I've got my new RPi 3 and I Installed OpenElec 6.0.3. on it so far so good.
But when I'm Looking at the Hardware Information on Kodi I got This:

CPU: ARMv7 Procesor rev 4(v7.I)
BoGoMips: 76.00
Hardware: BCM2709
Revision: a02082
Serial:***************
CPU temperature: 82 C
CPU speed: 1200

CPU speed is right but CPU and Hardware NOT imo
This is what it should be:
Quad-core 1200MHz 64bit ARMv8-processor (BCM2837 chipset)
or am I wrong here?
Is this a OpenElec Issue or Do I have a wrong RPi3?

If the onboard Wi-Fi is working then your RPi must have a BCM2837.

I believe from other comments that is correct but confusing, but as long as you get Revision a02082 it is a RPi 3B

I've just dd'd 2016-02-09-raspbian-jessie-lite.img onto a MicroSD, and my Pi 3 gives:

There is an outside possibility that ARMv7 is reported as the powers that be realised that all the GPIO libraries might be broken if ARMv8 was reported.

[lb]

It is perfectly normal that ARMv7 is reported. The CPU is capable of ARMv8, but Raspbian and all other distributions still use a 32 bit ARM kernel and userland. The CPU boots up in 32 bit compatibility mode.

[IanH]

I was just reporting that I got half the BogoMIPS that @RaTTuS had, which seems a little odd. Using lscpu I get a likely looking:

Re. ARMv8, I'm guessing it won't be possible to boot a 64-bit kernel (e.g. one of Linaro's) without support from Broadcom. The start.elf has to magically set up a load of memory data structures and ARM registers before it lets the ARM run kernel.img. I don't quite understand how it does this, but it'll be different between AArch32 and AArch64 ABI's. So almost certainly 64-bit support won't be possible without a new start.elf, which is proprietary BCM code.

Hi everyone,

I just got a pi 3, my goal is to have it running nextcloud and kodi.
I was checking temperatures and found something wierd. No matter how many firefox instances I open simultaneosly cpu freq never goes higher than 800. At idle it sits at 600mhz. Temps are around 57ºC at idle ( room temperature around 32 ).

This is the output of the comands that you suggested to check the cpu.

Shouldn´t max CPU Mhz be 1200¿
Also I´m getting a maximun of 5Mbits on internet tests when my windows computer gets 15, so I´m worried that this pi 3 could be faulty.

Thanks in advance.

/proc/cpuinfo does not report the cores as ARM Cortex-A53 when running in 32 bit mode for two reasons:

The kernel is a V6 kernel; it is unaware of the V8 architecture so the CPU cores must present themselves in a way compatible with the V6 (Raspberry Pi 1)

Many drivers, libraries, services, utilities, and the kernel itself, use the information in /proc/cpuinfo to determine how to behave.
