Benchmark tests compare Snapdragon 820 with various chipsets including the A9, SD-810 and Exynos 7420

The first test measured CPU performance thanks to Geekbench. Eight tests were run back to back to stress and heat up each device. The Apple iPhone 6s Plus, powered by the A9 chipset, had a remarkably consistent score throughout all of the CPU tests (as did the SD-820 on the Galaxy S7 edge). The A9 had the highest single-core score among the chips tested, putting up numbers in the 2512-2529 range. That was followed by the 2307-2341 range of the Snapdragon 820. The latter, packed inside the Samsung Galaxy S7 edge, put up the highest multi-core scores proving that it isn't the number of cores that is important, it is the power of the cores that matters.
While the Exynos 7420 showed a large drop in single-core results (1472-1480), the multi-core scores (5018-5148) were high enough to challenge the Snapdragon 820. The Snapdragon 810 showed signs of throttling as the benchmark scores declined over the course of the eight tests.
During the CPU testing, the iPhone 6s Plus and the Galaxy Note 5 were both cool under pressure at 83°F. The Galaxy S7 edge reached 84°F. The Moto X Pure Edition hit 88°F on the thermometer while the Nexus 6P was the warmest with a reading of 95°F.
Testing the GPU of each phone using 3DMark, the iPhone 6s Plus and the PowerVR GT7600 GPU started with the highest score, faltering a bit over the five back-to-back tests. The phone also was the warmest after testing, hitting 104°F. That was an increase of 16% from its temperature at the start of the test. The Adreno 530 GPU running graphics on the Galaxy S7 edge also showed some stress over the course of the test, but ended up with the highest score, edging out the A9 at the end. The temperature gain after the fifth test was 10%. The Adreno 418 on the Moto X Pure Edition has been criticized and it did finish last in the test. At least there was no rise in the temperature of the device after five rounds.
XDA did note that despite the increase in performance brought by the Snapdragon 820, it still found that the UI on the Galaxy S7 edge suffered from lags, stutters and frame drops. During GPU testing, more frames were skipped while browsing through the Google Play Store when compared with a pair of near stock phones powered by the Snapdragon 810 (Nexus 6P, OnePlus 2). Another issue found the screen randomly freezing, preventing any input from being read in the settings and camera apps. Keep in mind that different handsets could produce different results with the same chipset inside.

This is why I'll be getting the Exynos variant instead of the sd820 powered s7

This is a click bait for fanboyism wars.. While in reality, all these chips deliver on day to day uses

Not click bait for fanboyism wars Its a great investigation into if these phones can sustain performance, particularly important for gaming/VR This article is better than any of the other articles posted here this month Problem is this site is full of fanboys To be fair the rest of the internet is too But this site is particularly bad

Not sure how your comment correlates to the data shown from xda's tests. 530 doesn't do anything other SoCs don't, but works better than a number of them. What one can see from the 810/808 comparison here, is that the extra A57s are the source of the throttling. GPU is so much more important for fluidity. An underclocked 530 should prove to be sufficient for anything today short of the most demanding 3D games. I'm looking forward to what Meizu and HTC produce this year. Samsung's out for me. LG is still a possibility depending on the cam and the battery.

The Sd820 is better than the E8890 tho...... Based on benchmarks and not RL testing of course.

I have the SD820 S7 edge and i wish if i waited and got the E8890 because i used samsung phones before and they all et hot under some situations including the S7 edge. and note 5 is my first exynos phone that i had never experienced the heat problem. i don't know why samsung went with SD for us this year. beside e8890 hasn't been but in a test yet

Ok, I'll take your word for it. You can always sell and buy the international version, I guess it would be better to buy the international version first before you sell because it could be worse lol. Honestly getting hot isn't really something that should be a huge problem......Put a case on it lol. There are some benchmarks on the E8890.

It is being built on 14nm labs from Samsung. The note 5 and s6 were samsung's sole customer for the tech until now. The iPhone 6s, Snapdragon 820, and even the upcoming Polaris gpus from amd are all being made at Samsung's fabs

No matter what... thwre are still stutters! Why? I dont think its the hardware issues. I had Note 2, S5, and S6. S6 had most stutters! Well, both Note 2 and S5 were rooted with custom ROMs. Hopefully S7 variants can be rooted.

This post should silence all those who say Exynos 7420 throttles as much as 810. Also to those who say A9 doesn't throttle( it does under GPU load).

Still, no diff in real world usage

If you play "intensive" games on your phone, then there is potentially a real world difference But that would need another investigation since each game performs different Eventhough I dont play "intensive" games, this article is still interesting IMO

What about this most recent test using the S7 vs iPhone 6S? Some throttling was done, or below par RAM management. /shrug

test like that is just useless -_- open 30 chrome tab, minimize it, do speedtest, and return to chrome to see it reload or not, that will be more like RL case, lol (it also have better camera, microSD, and water resistant)

Is it Benchmark tests? XDA Forum- Ahaha, biased and dumb ass site. This site is a joke, Look that - xda-developers.com/xda-external-link/s7-edge-teardown-reveals-no-liquid-in-the-liquid-cooling/ It's a best fake test. Checkout, AnTuTu’s Report ：TOP-10 Performance Smartphone Chips 2016 - antutu.com/en/view.shtml?id=8200

Claiming XDA to be dumb and antutu to be reliable! Boy, you must be smart.

So far, so good. The fingerprint scanner is much quicker, the overall phone is just a tad snappier, but nothing to write home about. I haven't done a full wipe yet, I'm trying to work up the ambition to set everything up again. But very stable, still speedy. The FingerSecurity.app isn't working entirely correctly, I'm not sure if it's M ready. I think I'll uninstall/reinstall it. But for an OTA installed on top of the old version, it's about the most stable I've seen. Oh, and the touchscreen seems more responsive.

I currently have no thoughts. But the initial impressions of 820 don't look good for the sustained performance( the GPU clock seems a little too high, CPU seems fine). About the s7, I don't have a high regard for any Samsung phone right now. I'd suggest to keep away from Samsung. The initial software is near perfect, then they ruin it with an update and don't fix the issues. Add to the fact that the s6 doesn't have marshmallow yet and you get a disgusting experience. Samsung doesn't know how to run software. You always think they'll fix it, but they never do. I'm surely not buying their phones again.
