an interesting test that compares the Snapdragon 820 in the Galaxy S7 Edge with its predecessor S810 Nexus 6P, but also with the Apple A9 (iPhone 6S Plus appeared on the XDA forums) , the Exynos 7420 (Galaxy Note 5) and Snapdragon 808 (Moto X). The Snapdragon 820 wins the war on just about every front.
The test considers Geekbench (CPU) and 3DMark (GPU) , and were also measured the temperatures reached by the various devices after several sessions of the benchmark. In this regard, it should be noted that the thermal performance does not depend directly on the processor, or at least not only, but especially from the smartphone’s design took into account.
Predictably, in the single-core Apple A9 test confirms the first of the class, closely followed by the Snapdragon 820. The latter, however, is the first in the multi-core test , which is also a predictable outcome, while the Apple chip ends up third from bottom also passed by Notes 5 (Exynos 7420) and Nexus 6P (S810).
The Samsung processor last year, by the way, is not far from the Snapdragon 820 in this specific area. The Snapdragon 820 instead shows an ‘ impressively consistent results , surpassed only from the A9 Apple – which shows virtually a straight line even in the multi-core test.
The smartphone tested were fresh relatively , with a maximum temperature of just under 40 degrees – which may seem a lot but we must consider the extreme conditions of the test, far from a situation of actual use. The Snapdragon 810 is the model that shows the most obvious drop in performance with increasing temperature (throttling).
| 3D Mark | Initial T (F / C) | 1 | 2 | 3 | 4 | 5 | Final T (F / C) |
|---|---|---|---|---|---|---|---|
| iPhone 6S + | 90 / 32.2 | 2759 | 2561 | 2469 | 1900 | 2076 | 104/40 |
| Galaxy S7 Edge | 90 / 32.2 | 2511 | 2519 | 2480 | 2103 | 2090 | 99 / 37.2 |
| Note5 | 90 / 32.2 | 1258 | 1246 | 1244 | 1199 | 1232 | 97 / 36.1 |
| Moto X Pure | 91 / 32.8 | 1023 | 973 | 995 | 1001 | 968 | 91 / 32.7 |
| Nexus 6P | 95/35 | 1330 | 1180 | 1283 | 1185 | 1141 | 97 / 36.1 |
| HTC M9 | 93 / 33.9 | 1401 | 1266 | 1338 | 1144 | 1082 | 97 / 36.1 |
The tests show that the GPU all smartphones have a drop in performance more or less pronounced gradually rising temperature. If the iPhone part in the first place, in fact, in the long run GS7 can keep a higher score. Others in the party smartphone remain significantly behind the top two. They thus confirm what has been said in the past by Qualcomm: the new S820 has performance much higher than ever before, and easily beats all other Android smartphones taken into account.
The measure also shows an increase in temperature for all smartphones, but more accentuated in the case of the product Apple , which rose from 32.2 to 40 degrees. The Galaxy S7 goes from 32.2 ° to 37.2 °, and Notes 5 from 32.2 ° to 36.1 °.
The numbers confirm then again the ‘ Excellent performance level to be reached with the Qualcomm Snapdragon 820. The conclusions of the tests, however, point out that the results should not be taken as an absolute indication concerning this processor, because there are many variables that could lead to different results.
The authors also claim that in spite of everything “we still managed to see the lag UI , including stuttering and random frame drops. Blame the software developed by Samsung, which from this point of view it does go Snapdragon 820 also worse than the Snapdragon 810, which is coupled to the interface on Nexus 6P stock Android. They were also detected real interface blocks, where for a few seconds was not can do anything.
