Samsung Exynos 5 Octa  vs Qualcomm Snapdragon 600 

Maybe I have a higher binned SD600, but the APQ8064T in my Nexus 7 (2013) has a 2GHz OC, with the minimum CPU frequency undervolted to 825mV . . . . and she's been stable and smooth as buttery goodness for well over 2 years now. I use my N7 2013 as my Kali tablet, and with MultiROM on-board, I can switch over to CM 14 (Nightly) as easy as a quick reboot. In all honesty, once I flashed Flar's ElementalX Kernel, it opened up a world of possibilities that were definitely out of reach at stock speeds and settings. All of the spec pages for the N7 2013 (Flo & Deb) list the SoC as the S4 Pro, but further investigation has shown that it is indeed a Snapdragon 600, verifiable by the ability to check the binning with (after a soft reboot): su cat /proc/last_kmsg | grep acpu It seems like all HTC One M7's are SPEED BIN: 1, where all N7 2013's are SPEED BIN: 14, so it looks like they represent versions or revisions, where the PVS values are between 3 and 6, with 3 being the most common. The PVS value is how the kernel loads the voltage table, and the higher the value, the lower the stable voltage is for the CPU frequencies. So they aren't lower binned SD600's in the N7 2013, just different, and DEFINITELY UNDERCLOCKED. So don't be afraid to push her a bit.

power consumption is clearly one big point beetween the 2 of these processors, since it uses the low power A7 processor most of the time. and its 4 threads not 8, not sure if the l2 cache per core is accurate. i had the samsung galaxy s4 with S600 and now the Exynos variant and im very happy with its performance and battery use.

So did you fix it up? It's very intriguing to see it listed as a 8 core instead of a 4+4

The results are totally opposite here http://www.gsmarena.com/samsung_galaxy_s4_i9500_vs_i9505-review-930p2.php

Good point, we'll see if we can get this fixed up

It's not really an 8 core processor, it's a big Quad core Cortex A15 chip clocked at 1.6GHz and a smaller Quad core Cortex A7 chip clocked at 1.2 GHz. Note that only 1 set is active at any given time, depending on the processing load being processed.
