GPU Performance
While CPU benchmarks are currently a bit poor in nature, our GPU benchmarks are definitely more helpful when comparing between devices and across platforms. In the case of the Galaxy Note 4 with a Snapdragon 805 we see the same Adreno 420 GPU clocked at 600 MHz that is also used in the Galaxy S5 LTE-A so performance should be relatively similar.
Once again, the Galaxy Note 4's GPU performance line up quite closely with what we expect from the Adreno 420. However, due to the higher 1440p resolution the performance improvements from the Adreno 420 are relatively small or none at all unless the application renders at 1080p.
NAND Performance
While NAND performance is generally an area where it's important to avoid dipping too low, there's are some cases that seem to improve in responsiveness with faster NAND, such as updating apps in the background while doing other tasks or similar cases where data committed to NAND becomes relatively random. In order to test this we use Androbench with some custom settings.
As one can see in the test results, Samsung continues to stay near the front of the pack when it comes to NAND performance. One shouldn't expect storage performance to become a bottleneck on this device.

Yep, different approach to low power design.Apple use just two underclocked but very beefed up, large cores, while Qualcomm uses more small, simple, but high clocked cores.
Just think about the fact that Snapdragon 805 probably doesn't draw more power than the A8, even while being clocked twice higher and built on a larger node.
If you doubt that, the Galaxy Note 4 itself is your proof - longer battery endurance than iPhone 6+(according to every other review) despite of having a modestly larger battery, supposedly less efficient OS, triple the RAM, bigger screen and larger resolution panel.
There's probably no way it could achieve that if snapdragon 805 was any less efficient than A8

One more thing.. the CPU benchmarks posted here are nothing but a single threaded Web scripts. Which means, almost entirely dependant on software optimization and single core performance.If you want a good raw performance indication of the CPU setup itself, look up Geekbench.
There the Snapdragon 805 easily beats the A8 in overall score.
The A8 beats it even more easily in the single core part though.

Not many apps are designed for multicore support. Also, Apple chips run at top speed for longer. It's like comparing Carl Lewis to Paula Radcliffe. Lewis can run faster for short bursts but Radcliffe has more endurance and is still running at the top of her game after 26.2 miles.KPOM - Wednesday, October 15, 2014 - link
Not necessarily. The biggest drain on the battery is the screen. OLED is more efficient than LCD. So perhaps the Qualcomm CPU is less efficient but Samsung makes it up in the display. Now that Samsung seems to have solved the saturation issue perhaps the real story is that if Apple and Samsung were still partners instead of frenemies the battery life on the latest iPhones would be absolutely amazing instead of just good considering the smaller batteries they use.tralalalalalala40 - Saturday, October 18, 2014 - link
not more efficient when browsing the web (white background)tralalalalalala40 - Saturday, October 18, 2014 - link
Because you were lied to by a 100 billion dollar marketing machine. more megapixels is not better (if you don't account for pixel size etc.). more RAM is not better (if you don't account for fast memory compression techniques). more clock speed is not better (if you don't account for electromigration and current leakage, etc. in the transistors).techcrazy - Wednesday, October 15, 2014 - link
Samsung amoled display doesn't appear as sharp as other LCD display. It's because of their PenTile subpixel layout. Their PentTile subpixel layout is lower than a conventional RGB stripe, so true subpixel density increases around 20%. - So basically Samsung's QHD display only 20% sharper than FHD display which has RGB stripe where as LG's QHD display is nearly 80% sharper than FHD display which has RGB stripe. LG's QHD display is the true QHD display and Samsung's QHD is the fake QHD display.grayson_carr - Wednesday, October 15, 2014 - link
Doesn't change the fact that the G3 display isn't very well calibrated, has very poor contrast, and has a terrible oversharpening algorithm that makes things look weird.MattL - Wednesday, October 15, 2014 - link
Good review... two things though:1) Your screen analysis results differ from display mate in an oddly large way, different review unit calibrations maybe? They found it to rate much better on accuracy results than here.
2) Battery life results differ a bit than most other sites, they find the note 4 does better than the iPhone 6. In fairness the web browsing results is where it rates the lowest which is where the iPhone 6 barely beats it here, so that doesn't different too much.
Why don't you do a video battery life test? Or a mixed content test. These are areas that OLED screens should do much better due to white screen vs black energy efficiency, something display mate analyzed in much more detail.

Don't you think strange that diplaymate submit the test weeks before the launch ?Same thing with Galaxy Alpha and GSMarena review.
I really suspect Samsung chosing prototypes. Every other review after launch never meet those results.
