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.

You have to love the 3DMark "onscreen" vs "offscreen" results. As long as any Android doesn't have to actually render images on the screen for the user than it is just as fast as an iPhone. ROLMAO.Announcer97624 - Saturday, November 1, 2014 - link
I don't get the point about battery life trailing behind the IPhone 6 plus? The IPhone 6 plus doesn't have a removable battery so on a 16 hour plane ride the IPhone 6 plus is a liability not an asset compared to the Galaxy Note 4's ability to have a few spare charged batteries. While I have the European Galaxy S5 4G LTE I have a battery wallet with six fresh batteries so I can go for most of a week without charging. My girlfriend has an IPhone 5 and is now going to purchase the Galaxy Note 4 specifically because of the non removable battery on all IPhones.Bikerboy89 - Saturday, November 8, 2014 - link
Wow onscreen GPU performance is laughable. Really bad vs the competition from apple and Nvidia. My LG G Flex gets better onscreen performance in gfxbench and the iPhone 6 gets double or triple Note 4. Pretty pathetic for a flagship device.MattL - Wednesday, November 19, 2014 - link
I finally realize why your color accuracy results differ so much from display mate, where you find the iPhone is more color accurate they found the Note 4 more accurate.http://www.displaymate.com/news.html#Color_Accurac...
"Recently some reviewers have published articles contradicting my Absolute Color Accuracy Measurements for the Samsung Galaxy S5. For example, see this recent review in phone Arena. The problem is that these reviewers are not scientists or display experts, and are using canned display calibration software incorrectly in order to test a display, which produces incorrect results and bogus conclusions. Below is a brief semi-technical analysis...
The Color Difference dE used by the Reviewers Incorrectly includes the Luminance: The reviewers are using retail display calibration software products that use a Color Difference measure called dE, which includes a Luminance (Brightness) Error component in addition to the Color Hue and Saturation (Chromaticity) Error component. Using the Color Difference dE is appropriate for setting the display calibration, but dE is Not a measure of Visual Color Accuracy (Hue and Saturation) because it also includes the Luminance (Brightness). The eye sees and interprets brightness and color as two separate visual issues - dE combines them together. So all conclusions based on using dE for Visual Color Accuracy are incorrect.
Our Color Accuracy only includes Color Hue and Saturation: Since the eye sees color and brightness as two separate visual issues I measure and analyze them separately. My published Absolute Color Accuracy measurements and data analysis includes only the Color (Hue and Saturation) Chromaticity Error component Δ(u'v') or d(u'v'), which evaluates just the difference in Hue and Saturation seen by the eye, and is plotted on a 1976 CIE Uniform Chromaticity Color Diagram in all of my articles. This is the correct method for evaluating Visual Color Accuracy (Hue and Saturation). Compare my very precise and detailed Absolute Color Accuracy plots with their crude figure."
Basically you're doing it wrong anandtech

this phone lags on ui and on games like deadtrigger2, don't trust benchmarks! specially when its samsung..... benchamrks are only meaningless numbers!(well useful in some cases)
