kada smo vec kod exynosa
uticaj na bateriju :
The Galaxy S7 does fairly respectably here, although the Snapdragon 820 version is definitely showing either architectural or implementation inefficiency here when compared to the Exynos 8890.
A delta of about 10% means that the Exynos 8890 GS7 uses about 1.38W average here while the Snapdragon 820 GS7 uses about 1.51W in this test assuming that the battery capacity is nominal. If you subtract out an estimated display power the delta that can be attributed to non-display factors is something like 30% here. Interestingly, the HTC 10 is mildly more efficient here with its higher density LCD, with the AMOLED display consuming something like 10% more power despite the presence of dark-themed webpages to try and bring some balance here.
However, for whatever reason it looks like the Galaxy S7 edge ends up with similar oscillating throttling behavior. Interestingly enough, even though the Galaxy S7 spends more time at higher performance states than the HTC 10, it manages to last longer, which is likely due to the lower APL of this content in conjunction with forced power save modes, and higher sustainable skin temperatures due to the glass back with heatpipe cooling to help distribute heat.
The improvements here aren’t necessarily going to blow you away unless you get the Exynos 8890 variant, but it’s good to see that we’re finally back to improving on battery life with the launch of the Snapdragon 820 compared to the Snapdragon 810 and 808’s rather disappointing power efficiency due to the use of a high-power implementation and process node. I’m not sure the Snapdragon 820 is really the best design we’ve seen on 14LPP when it's more on par with 14LPE SoCs for efficiency, but it’s good enough that it doesn’t fundamentally compromise a device.
performanse:
As hinted by the PCMark results, the Galaxy S7 with the Snapdragon 820 is really nothing to write home about when it comes to actual software optimizations, while the Exynos 8890 version is significantly faster in comparison. The fastest devices by far here are still the Kirin 950-equipped phones, but even from cold start launches the HTC 10 is comparable, and pulls ahead slightly when the applications are pre-loaded into memory. The OnePlus 3 and Xiaomi Mi5 are closer to what the S820 GS7 should be achieving, which is really more a testament to just how strangely slow the Galaxy S7 with Snapdragon 820 is.
Overall though, the Galaxy S7 in both iterations are acceptably fast for general purpose tasks. However, with that said the Snapdragon 820 variant is noticeably slower, and the software stack seems to be less optimized for whatever reason even after multiple post-launch OTAs and all the latest app updates. Given that these devices have locked bootloaders
it's difficult to really go deep and try to figure out exactly what's causing these issues, but it's likely that Samsung Mobile has the engineering staff to do this and resolve these issues as a 600 USD phone really shouldn't be performing worse than a 400 USD phone. On the bright side, the Exynos 8890 variants perform quite well here, with performance comparable to top devices and often beating out Snapdragon 820 devices, although usually not by a huge margin.
SoC performance, as well as storage performance are all commendable, but in general I don’t think there’s really been an appreciable change in the landscape with regard to SoCs. Snapdragon 820 and Exynos 8890 are both decently fast, but their speed is not really all that notable compared to Apple’s A9 SoC, especially when you consider things like browser performance which is heavily reliant on single-threaded performance. Kyro/Cortex-A72 is as good as you can get in the Android ecosystem at this time, so among Android phones this is top-tier performance, but in the broader landscape it's going to be overshadowed by what Apple has done.
The Galaxy S7 with Snapdragon 820 is also strangely slow in real-world situations as seen by Discomark, which is honestly somewhat puzzling. Samsung needs to put some real optimization effort into their Snapdragon devices as they actually trail the competition here to some extent, although if you aren’t that observant it’s unlikely you’ll notice a huge difference. Storage performance is great, but not really comparable to the iPhone 6s. This isn’t really a function of NVMe or UFS, but the design of the storage system itself. Given that Samsung is developing fairly small BGA SSDs already, I suspect the delta will go away soon. If you take away Apple devices, Samsung continues to ship some of the best storage on the market.
displej:
On the display side, Samsung continues to ship great AMOLED displays. While efficiency is not appreciably improved relative to the Galaxy S6 I would say that the best AMOLED panels now are greater than or equal to the best LCD panels. If Samsung can figure out how to reach efficiency parity with the best LCDs regardless of displayed content I would say that high end smartphones should really only be shipping AMOLED, but this is conditional upon whether OEMs can actually source these panels. Regardless, the Galaxy S7’s display is pretty much the best you can get in an Android device.
