The Samsung Galaxy Note 4 has been with us for absolutely a while now. As we know, the accessory comes with two variants afar on SoC basis. The Samsung Galaxy Note 4 comes in two variants with the Qualcomm Snapdragon 805 on one and Samsung’s centralized Exynos 7 Octa on the other. The Snapdragon 805 is apparently the aftermost acme jewel in the ARMv7 32 bit architectonics aback things are now affective to the 64 bit ancillary of things in the adaptable accouterments industry, with Apple already accepting taken the advance ancient aback and the Nexus 9 afterward suit.
The Exynos 7 Octa on the added duke is awfully altered from the Snapdragon 805 in agreement of architecture. Compared to the cloister amount architectonics of the 805, the Exynos 7 Octa comes with two sets of cloister ARM Cortex A53 and Cortex A57 cores on board, with CPU endless alternating amid the two, or utilizing them absolutely depending on the accretion ability required. But that’s not the alone affair that sets both the tablets apart. So today, we’re activity to booty a attending at things in capacity and see which alternative does end up alms up the best amount for your buck. If you appetite to see what makes both the versions beat in detail, apprehend the absolute post. If however, if you aloof appetite to see which accessory comes on top, booty a attending at the cessation at the basal of this post.
As mentioned above, the Galaxy Note 4 comes with two altered CPUs on board, namely the Snapdragon 805 and the Exynos 7 Octa. Both the SoCs are awfully altered in attributes as accent above. But lets booty a attending at what’s beneath the awning of both the 805 and the Exynos 7 Octa, and see which one should action added performance, and added importantly, ability efficiency.
The Snapdragon 805, back compared to its predecessor, the 801 sees bashful improvements in agreement of CPU performance. It is based on the ARMv7, Krait 400 CPU architectonics which is ARM’s almsman to Scorpion CPUs and is in action aback 2012. The Krait 450 in the Snapdragon 850 is a basal advancement to the Krait 400 begin in the 801.
Notable appearance of the Krait series, or the Krait 450 in accurate accommodate 2 MB of L2 cache, 3 way break and 4 way out of adjustment command execution, which basically agency that the Snapdragon 805 will be time able back active commands by active them in the adjustment of ascribe abstracts available, rather than the adjustment in which commands accept been received. The Krait alternation additionally executes added than one command per aeon through accompanying allocation of instructions to assorted CPU parts. A affection on the Snapdragon 805 which will additionally be discussed on the Exynos 7 Octa is ARM’s MPE (Media Processing Engine) which provides for able dispatch of media.
The primary advance on the 805 is the Adreno 420 GPU which offers up to 40% of added achievement back compared to the Adreno 330 begin on the Snapdragon 801. The Adreno 420 has a alarm acceleration which variates amid 500/600 Mhz. Pixel amount for the Adreno 420 comes out to be 7.2 GP/s. The Adreno 400 alternation additionally supports OpenGL ES 3.1, Direct3D 11.2, and OpenCL 1.2. A abrupt arbitrary of the Adreno 420’s alive can be gauged from Qualcomm’s diagram above.
Coming appear the Exynos 7 Octa, Samsung’s in abode alms is no underdog back it comes to CPU and cartoon performance. Featuring four Cortex A53 and four Cortex A57 cores, the Exynos 7 Octa is based on an all new ARMv8, 64 bit architecture. What this about agency is that alike admitting the college clocked cores of the Exynos 7 (A57 cores with a abundance of 1.9 GHz) accept an all-embracing lower abundance back compared to the 2.7 GHz per amount the Snapdragon 805 offers, the Exynos 7 still manages to booty the brawl back it comes to performance.
In areas of RAM and ability consumption, the allegory amid the two SoCs after-effects in no bright winner. The Exynos 7 Octa with its 20 nm HKMG accomplishment action is added ability able back it comes to the Snapdragon 805, which is bogus on the 28 nm HPM process. The anamnesis controllers for the Exynos 7 Octa appearance 825 MHz of bifold approach 32 bit LPDDR3 with a GBPs amount of 13.2. The Snapdragon 805 on the added duke appearance a hardly lower clocked 800 Mhz of 64 bit bifold approach 64 bit LPDDR3 anamnesis with a college GBPs amount of 25.6 GBPs. ARMv8 additionally appearance annex affirmation for avant-garde apprenticeship administration and avant-garde SIMD which is agnate in attributes to the Snapdragon 805’s MPE mentioned aloft but additionally uses 128 bit registers for bigger media processing.
The GPU for the Exynos 7 Octa is the latest in ARM’s Mali ambit of GPUs with a absolute amount calculation of 16 cores on board. Back it comes to frequency, both the Adreno 420 and the Mali T760 accomplish toe to toe with the best abundance for the T760 actuality 600 Mhz as well. The Mali T670 comes out on top in pixels rendered, with a account of 9.6 GP/s. For amphibian point scores, the Mali T760 has a account of 20.4 GFLOPS per core.
Compared to this, the Adreno 420 has absolute GFLOP array alignment amid 330-388. While these ability complete complicated at first, a criterion assay for both the GPUs helps put their about achievement in a abundant bigger perspective. The Mali T760 additionally supports OpenGL ES 3.1, OpenCL 1.2 and DirectX 11.1.
Now that we’ve apparent what makes the Exynos 7 Octa and the Snapdragon 805 different, its time to see how these stats are adapted into absolute activity performance. We’ve been able to get our easily on some all-encompassing CPU, browser and GPU benchmarks of both the variants of the Galaxy Note 4, so lets booty a attending at these below.
Processor benchmarks for the Galaxy Note 4 appearance alloyed results. The Snapdragon 805 manages to flash confidently in the majority of Antutu’s altered tests agitated out. The areas area the Exynos 7 Octa Galaxy Note 4 manages to flash are all-embracing RAM achievement and multi-thread CPU accumulation and amphibian point. RAM array for the Exynos 7 Galaxy Note 4 can be explained somewhat through the stats mentioned above. Multi-thread after-effects for Antutu are absolutely cocky allegorical back it comes to the Exynos 7 with its eight cores. Booty a attending below. In all-embracing Antutu scores, the Exynos 7 Octa manages to booty a slight lead.

Coming appear the GPUs on the Galaxy Note 4, it is actuality we see the accurate ability of the Adreno 420 GPU advancement begin on the Snapdragon 805. As mentioned above, the Adreno 420 appearance as abundant as 40% added GPU achievement over its predecessor, the Adreno 330. ARM’s Mali T760 absolutely is no bout for its Qualcomm counterpart.
Another acceptable indicator of a device’s achievement back it comes to benchmarks are browser benchmarks in accession to all-embracing CPU benchmarks. Browser benchmarks for the Exynos and Snapdragon Galaxy Note 4 appearance alloyed results, with the Exynos 7 Octa already afresh demography the advance in multi-core achievement in accepted and additionally in several added aspects including memory, arrangement and overall. But already again, back it comes to graphics, there is no assault the Adreno 420, as can be apparent in the benches below.
Now for the moment of truth. After attractive in abundant detail at both the Exynos 7 Octa and the Snapdragon 805, and their about achievement on the Samsung Galaxy Note 4, its time to acknowledgment our aboriginal question. Which accessory is bigger ill-fitted to your needs and ends up carrying college amount for your money? Well, like all questions accompanying to accessories and devices, it appealing abundant comes bottomward to what your requirements are.
If you appetite your Samsung Galaxy Note 4 for raw accretion ability and processor resources, your best should be the Exynos 7 Octa adaptation of the tablet, easily down. Not alone is Samsung’s in abode SoC 64 bit, but it additionally end up carrying bigger accretion back it comes to administration ample amounts of loads. If, however, you charge your book for gaming and added multimedia purposes, the Snapdragon 805 Galaxy Note 4 is the one for you, with its above cartoon address of the Adreno 420. And if you’re a photography lover, break acquainted for our additional allotment on the Galaxy Note 4 analysis, which will awning the device’s accurate capabilities in detail. Cheers!
