The Android smartphone Samsung Galaxy Note 4 cuts in graphics performance and playing significantly worse than Apple’s iPhone 6 Plus. Demonstrate new benchmarks that Samsung only on paper has benefited from a display with higher resolution, a processor with more cores and higher clock rate, but which can not absolutely confirm in practice.
Specifications unequal power
Samsung Galaxy Note 4 is a variant powered by Samsung’s own Exynos 5 processor with 1.9 GHz clock speed and 8 cores, but of which only 4 are simultaneously active have. That’s why the Samsung’s advertising for “Octa Core” is more a marketing ploy. In addition, the smartphone is installed a GPU Mali-T760 type. Both the CPU and in the GPU uses Samsung Standard-chip designs from Apple’s iPhone ARM technology 6 Plus has Apple A8 CPU, which only has 2 cores and is only operated at 1.4 GHz. The Grade 4 also offers a resolution of 2560 × 1440 pixels and 3 GB RAM, while Apple’s iPhone uses 6 Plus with a resolution of 1920 × 1080 only 1 GB RAM.
In fact, the Galaxy Note 4, in the practice but working with photos and video or 3D graphics that are used in games, not keep up with graphics-intensive with the iPhone 6 Plus, as a series of benchmarks shows. Both devices are to be located due to their size with a display diagonal of more than 5 inches in like device class.
design flaw in Samsung CPU?
Current benchmarks from the GFXBench for OpenGL ES 3.0 and OpenGL ES 2.0 show that Apple’s iPhone 6 and iPhone 6 Plus land in any case before Samsung Galaxy Note 4 and, accordingly, before the Galaxy S5, which already could not compete with the iPhone 5s in the graphics benchmarks itself.
Samsung has a model with Qualcomm CPU available on the market in North America and Europe in Note 3. That will be just in Note 4. However, the CPU of the rod could only achieve a little more power than Samsung’s own Exynos solution, but not be faster than Apple’s iPhone 5s. It is assumed that this will be no different in Note 4. Now both Apple and Samsung are working (the Exynos) from the chip design itself. While Samsung decided to integrate an increasing number of CPU cores, the performance of the unit has not brought any significant improvements.
GFXBench – Results show inter alia Galaxy Note 4 and iPhone 6 Plus
The “Battle of the specifications” as Daniel Eran Dilger puts it, began in 2010, when still under Steve Jobs iPhone 4 with retina display was presented. Samsung was at that time very little experience with extra-large display and high resolution. But the Koreans have at least every year, if not more frequently, it is set in both the design and in the resolution up a notch. However, the processor design could not keep up with that speed. Apple only every 2 years was increased the resolution of the smartphone.
“Samsung Has pushed screen technology ahead of its own processor capabilities, Resulting in extremely poor performance in high definition. “
Daniel Eran Dilger
In theory, could Samsung CPUs offer more power, they will not need additional pixels operate in practice for the user show little qualitative benefits.
Why Samsung manufactures its own chips?
Although Samsung produces its own chips, the manufacturer relies on design of the rod with the Mali GPU and the “big.LITTLE” -CPU design that operates 4 cores with more power and 4 more cores are used only in standby. Other manufacturers such as Apple and Qualcomm (Snapdragon) operate their own chip design, which does not (more) based on the standards of ARM technology. As a result, the chips from Samsung are not very optimized.
This begs the question, why Samsung produces ever own chips. The manufacturer has collected certain know-how, as it has for years worked with Apple. But Apple began more than five years ago to work on the Apple A4, which was used in the iPhone 4 and the iPad first to implement its own chip design and since you have the manufacturer of chips for mobile devices in terms of performance behind left. Samsung could have emulate Apple, but has not made so many efforts. In fact, it sold its own Exynos chip is very limited in a few markets and sets the rest of the world in chips made by Qualcomm.
Samsung may Metal API not copy
Samsung can the software side not lend any option in many ways that optimizes the graphics performance, as does Apple with the new API for iOS Metal 8. Provided appropriate optimization, almost twice the performance advantage is even larger.
In particular, Samsung is doing yourself any favors so that they do not put on comparable hardware, even within a single product line or adjacent Prdoukt types. The Galaxy Note 3 and 4 respectively with two different CPU and GPU shipped (Exynos and Snapdragon). Taking the current S-series just adds even comes yet another graphics unit to (ARM Mali, PowerVR and Adreno).
