CPU Performance
For those unfamiliar with the Snapdragon 805, I would refer back to our previous posts regarding this SoC. This is Krait’s final hurrah in a high-end SoC, and is likely to be the best smartphone SoC available for the next 4-6 months as it’s built on TSMC’s 28HPm process, which has strained silicon and high-k metal gate at the transistor level in order to improve performance and reduce power. In order to test the CPU and general CPU-bound performance, we turn to our standard test suite of browser benchmarks. As said before, I’m not quite happy with the state of this suite but for now it can work to provide a decent relative comparison.
Overall, the Snapdragon 805 performs about as well as one might expect, although the benefit from higher clock speeds is generally quite minimal.

I think this is a US centric site and the Exynos variant will probably never be on sale in the US.gunsman - Wednesday, October 15, 2014 - link
Will you guys be getting the international version of this as well? Would love to see performance of A57/A53 compared to the 805. Would also love to see comparison of ARMv7 A57/A53 to (when it comes out) ARMv8 enabled A57/A53 to see benefits of new instruction sets and 64 bitmayankleoboy1 - Wednesday, October 15, 2014 - link
thisMost important think about the Note4 is the Exynos 5433 SOC, which is on the 20nm node. Snapdragon 805 is a known entity.

@JoshHo: You do know that the NAND performance measurements and comparisons between different OS and benchmark programs is not accurate, right? I own a Nexus 5 which, with Android L preview, achieves more than double the performance figures than with Kitkat. That same has been observed with other Android L devices: http://forum.xda-developers.com/nexus-7-2013/gener...I'm saying this because of the misleading graphs you provide, showing the iphones miles ahead of Kitkat android devices. Well, they are NOT. They are just on a different OS / benchmark. Iphones should be removed from the graph ASAP, or include some Android L preview measurements as well. Otherwise, the NAND performance graphs are highly misleading.

I don't have any particular reason to suspect Androbench pre-Android L, but I would expect some sort of compatibility issue with Androbench and Android L dev preview.NAND performance is generally not OS-dependent.

OS AND bench programI would expect a great amount of optimizations in the fs layer / kernel i/o scheduler and caching departments, together with newer controller device drivers of Android L. To make things simple: What if the compatibility issue of Androbench is with Kitkat and only with Android L will the true performance numbers show?
We will know soon enough...

LOL What are you talking about? The Galaxy Note 4 is a package of hardware and software. Your Nexus 5 has Android L Preview on it; The Galaxy Note 4 does not. It gets the benchmark rating that it gets, and the iPhone gets the rating that it gets.mpokwsths - Wednesday, October 15, 2014 - link
whatever....uhuznaa - Wednesday, October 15, 2014 - link
What's wrong with testing devices with the OS that they're actually delivered with? After all it's the performance you'll see in actual use.KPOM - Wednesday, October 15, 2014 - link
We all know that the first thing the average consumer does is root the phone and install a bootleg version of the OS.
