Samsung Galaxy S 6 and S 6 Edge: Previewby Joshua Ho on March 26, 2015 9:00 AM EST

Yesterday we received our Galaxy S6 and S6 edge review units. We’re still working on the final review but I wanted to share some early results from both devices. For those that are unfamiliar with these two phones, the Galaxy S6 range represents the result of Samsung’s “Project Zero”. In fact, the phones seem to have the internal name of Zero, which can be seen in terminal, and the build properties of both devices. For Samsung, these phones represent their attempt at completely rethinking how Samsung makes phones. There is a strong emphasis on a new unibody design, which has no visible gaps or screws. Rather than the plastic that previous Samsung phones have been known for, the new design is composed of metal and glass. Samsung’s design team has been given unprecedented control throughout the process of making this phone and the result of this is a Galaxy phone that looks unlike anything else they’ve ever released.
Even if design is important, it isn’t enough to make the phone. Samsung has also outfitted the Galaxy S6 and S6 edge with their latest technologies, from a new AMOLED display to a new camera module. The specs for both phones can be seen below.

Both the Galaxy S6 and S6 edge have Samsung System LSI’s newest SoC, the Exynos 7420, which has a cluster of four Cortex A57s clocked at 2.1 GHz, and four Cortex A53s clocked at 1.5 GHz. Compared to the Exynos 5433 of the Galaxy Note 4, this brings a new 14nm LPE (low power early) process, an upgrade to LPDDR4 memory, and a Mali T760 GPU with two additional shader cores. Outside of the SoC, the new display is advertised to bring a higher 600-nit brightness and a higher 1440p resolution. The front and rear cameras are both different from the Galaxy S5 as well, although the rear camera sensor may be shared between the two as the camera sensors are of similar spec. For this preview, we’ll focus on the system performance and display of these new devices, but as one can see from the specification table there is far more to look at for the full review.
For our system performance benchmarks we’ll start with our browser tests which can give a rough proxy for overall CPU performance.
The Exynos 7420 is about on par with the Snapdragon 810 in these benchmarks. Strangely enough both tend to do worse than the Huawei Honor 6 in these tests, which clearly can't be correct. As we've previously discussed, the stock browser will often give far better results due to OEM and SoC vendor optimizations. As a part of our updates to the benchmark suite for 2015, we'll take a look at Basemark OS II 2.0, which should give a better picture of CPU performance in addition to overall device performance.
The browser benchmarks seem to hide some pretty enormous variability as the Galaxy S 6 edge (which is comparable to the Galaxy S 6) sets a new record among Android devices. The only challenger is the iPad Air 2, which uses the A8X SoC with three Enhanced Cyclone cores and the semi-custom GXA6850 GPU.
This system test contains a floating point and integer test, in addition XML parsing, which means that this test mostly stresses CPU and RAM. Interestingly enough, the Exynos 7420 pulls far ahead of both the Exynos 5433 and Snapdragon 810 in this test, and approaches the A8X. The difference between the 5433 and 7420 is likely a combination of the higher clocks on both the A57 and A53 clusters for the 7420 (1.9/1.3 on the 5433, 2.1/1.5 on the 7420), in addition to the ability to stay at a high 'overdrive' clock due to reduced leakage from the 14LPE process. The One M9 likely falls a bit short here due to HTC's governor settings restricting the use of all 8 cores simultaneously.
While one might guess that the memory test of 'Basemark OS II 2.0 - Memory' is of RAM, this is actually a test of the internal storage. Once again we see the S6 edge come close to leading the pack due to the use of the new UFS (Universal Flash Storage) standard. Casual examination reveals that the S6 edge has a queue depth of 16, and that it identifies itself with the rather cryptic model name of KLUBG4G1BD-E0B1.

JeffFlanagan - Thursday, March 26, 2015 - linkHaving to unscrew something isn't a problem for most of us, but it's more likely to be a situation where you have to heat the phone and pry it apart, which I'd be hesitant to do. Of course upgrading phones every year solves this problem, and all I really need is three hours of battery life since I have power at home, at my office, and in my car.
sleepeeg3 - Thursday, March 26, 2015 - linkYou have to heat the phone to pry it apart and several other things. It's a major ordeal.
Poik - Thursday, March 26, 2015 - linkYou haven't seen the S6 teardowns have you? There's no screws just hidden fasteners and a shit ton of glue. I don't know about the new iPhone6 and 6+ but by comparison an older iPhone is very simple with those 3 screws.
nathanddrews - Thursday, March 26, 2015 - linkNon-removable battery and lack of SD are deal-killers, unfortunately. The integrated wireless charging is wonderful, but being forced into a service contract just so I can get a new battery in a year is not happening. My S3 has seen two battery replacements in its lifetime. If not for the option to install a Qi charger, my buggy USB charging port would have killed it as well. As for the missing SD slot... just no.
Oh well, a used S5 will be a decent upgrade when it comes time.
hrrmph - Friday, March 27, 2015 - linkMy thinking exactly. This S6 is so bad that when it comes time to upgrade, the S5 might be the logical choice.
Novacius - Thursday, March 26, 2015 - linkDisplaymate already tested the display of the S6. It needs 20% LESS power at the same brightness than the S5's display, despite it's higher resolution. I think it's awesome.
Novacius - Thursday, March 26, 2015 - linkThe SoC should also be much more efficient (14nm) and they use LPDDR4 now, which uses lower voltages. I'm not very concernced with battery life.
Thermogenic - Thursday, March 26, 2015 - linkMy understanding is that Samsung's 14nm is not comparable to Intel's 14nm. It should still be better than what they were doing, but not quite as impressive as Broadwell's gains were/are on the PC side of the house.
Novacius - Thursday, March 26, 2015 - linkYou're right, but it's still better than every other ARM chip at the moment in terms of production process. And it's also pretty close to Intel I guess. Compared to Samsung's 20nm Exynos 5433, the GPU now needs up to 300mV less. That's HUGE.
Azurael - Thursday, March 26, 2015 - linkMaybe, but every past Samsung SoC has run far hotter than comparables from other manufacturers, so I'll believe it when I see it.
