Until I see benchmark results, I call BS on all those rediculous RPi OC results. There was a guy at OCN claiming 5GHz on ln2 too, but obviously tha's BS too.
So far, most cap out at 1200-1250 on air cooling with overvoltage=8.
The Odroid-U2 is indeed an awesome little thingie, with a lot of performance and only consuming max. 10W! I haven't figured out how to 'OC' it beyond 2GHz.
Hardkernel now also has an ODROID-XU with Samsung Exynos5 Octa big.little design (4x Cortex-A15 @1.6Ghz + 4x Cortex-A7 @1.2Ghz). It starts shipping in September and is now $149 pre-order. Unfortunately you can only use 4 cores at the same time.
It would be interesting to see the performance differences between the ARM architectures (ARM6, Cortex -A7-A8-A9-A15)
Phone is Lenovo A820 with Quad-core ARMv7 MT6589 chipset + SGX544MP video. What is the correct category to submit?
Unfortunately MTK-based phones can't be overclocked yet, so I'm stuck at 1.2GHz.
BTW, it's using 2 threads only, don't know why - maybe it's because I'm running it chrooted (as a slave OS).

Anyone having fun yet?
Me! Awesome little thingie.
yeppers!!!
I'm gonna update the article with some information on 3D benching and influence of PSU.
Awesome guide!
And yes, the JDK8 1.8.0-ea-b100 is very good on ARM devices. I think it is because of the VFP support.
On my ODROID-U2 (4x ARM Cortex-A9 @2,0) I got a score of 2419,06 with Ubuntu 13.04
But the CPU needs to be added to the database before I can submit, so just a link for the time being:
Awesome, is that Linux on your Galaxy Note?
//edit: just figured out it's an Odroid Hardkernel. Nice. Couldn't help myself and just bought one as well
I have been playing quite alot with it now. Still having a hard time getting Java 1.8 to work on Arch linux
Just ordered 2 more units after I found this person: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=51119&p=395436
running 1400mhz arm_core
My first unit are having problems with higher than 1165 mhz arm_core and that only gives me 540 points

Hey, I get it working like this:
pacman -S vim
(I'm used to working with vim to write/edit txt files)
wget http://www.java.net/download/jdk8/archive/b100/binaries/jdk-8-ea-b100-linux-arm-vfp-hflt-24_jul_2013.tar.gz
(or go to the oracle java 8 website and download from there)
tar -xzf jdk-8-ea-b100-linux-arm-vfp-hflt-24_jul_2013.tar.gz -C /opt
export PATH=$PATH:/opt/jdk1.8.0/bin
(link Java to system variables, you have to do it each time you reboot)
java -version
(check if Java is working)
wget http://downloads.hwbot.org/hwbotprime.jar
java -jar hwbotprime.jar
Set this in ~/.bash_profile and you don't have to type it after reboot.
echo "export PATH=$PATH:/opt/jdk1.8.0/bin" >> ~/.bash_profile

Got it working on my smartphone. First I tried Debian, but couldn't solve the java command symlink.
Although there was a symlink in /usr/bin, it was still reporting that there's not.
So I've installed the Raspbian.
Here's my first run: http://hwbot.org/submission/2412106_i.nfrar.ed_hwbot_prime_4x_arm1176_s_1360.94_primes_per_second

Use this category: http://hwbot.org/hardware/processor/mediatek_mt6589/
You can manually increase the threadcount with hwbot prime. Or do you think the OS is only using two either?
I'll check when I install it again, but I think it's due to the virtual machine mode.
And I'm Linux noob
You and me both, hehe. At least I now found out how to read a kernel, and I think with the right guide I'll be able to "update" an existing one.
