Samsung Galaxy Note 4: Exynos 5433 version apparently 64-bit capable

With the launch of the Samsung Galaxy Note 4 including its own Exynos 5433 SoC made its debut. Despite some promising benchmarks were probably disappointed by the customer to be able to place the version with a Qualcomm Snapdragon SoC-805 in Europe acquire only the Exynos version of the Galaxy Note 4 – may be completely wrong. Well revealed that there actually is a 64-bit SoC with the advanced ARMv8 architecture on the Samsung chip. Irritating fact: Samsung has nowhere out
Update. As has Samsung Mobile Germany replied in a Facebook comment in this country the version with 805 Snapdragon SoC and 2.7 GHz seems actually to be sold, and not as anticipated, the variant with Exynos processor.
expressed Officially Samsung has so far not yet, but the present state of knowledge according to the Snapdragon 805 variant of the Samsung is Galaxy Note 4 come in North America, South Korea, China and Japan on the market, while in the remainder parts of the world the version with Exynos 5433 SoC will be available. Samsung has this handled similarly in the past, the designs with the in-house processors among customers usually enjoyed a less good reputation – sometimes due to severe vulnerabilities. But who needs whom to be jealous in the case of the Galaxy Note 4, in the light of the new findings difficult to say: As evidenced by some users on XDA Developers by means of a statement in Geekbench, is the Exynos 5433 SoC with a new ARMv8 architecture. And that would be at least this SoC 64-bit capable.
For the study, the processor ID of the listed as SM-N910U in Geekbench Galaxy Note 4 was considered that “ARM 65 architecture implementer 7 variant 1 part 3335 revision 0″ is. In comparison with the data at other devices where you knew the better processors, the identifier “Variant 1 part in 3335″ was identified as coding for the 64-bit-capable Cortex A57 processors. Again, this was not too easy to see, but with a view of the ARM documentation was found for the A57 chip encoding 0xD07, which corresponds to the decimal system of number 3335 – that this is not a coincidence, was a corresponding identification of the Cortex A15 chips (or 0xC0F 3087) ensured.
Pretty much effort for a not really new knowledge: Up to Introducing the Samsung Galaxy Note 4 one went really firmly believe that it would be an octa-core SoC with four ARM Cortex Cortex A53 A57- and nuclei, whereas the Samsung Galaxy Alpha nor the Exynos 5430 with four Cortex A7 – and four Cortex A15 cores is installed. In Geekbench, the performance differences show with an enormous gap in the Mult-core benchmark with 3228 to 4036 points – not surprising because of the new ARM Cortex CPU cores. Uncertainties concerning the composition of the Exynos 5433, however, arose when Samsung announced at the launch of the Galaxy Note 4 no details about the built practically processor. The Exynos order number 5433 actually does not fit the 64 bit compatible ARMv8 architecture, also implied that exhibited at IFA 2014 devices, that in them the Snapdragon 805 ticked – although even before it was clear that it again different hardware variants should provide for different markets.
The reason for the secrecy is probably in marketing. Although Qualcomm is a renowned developer of processors for many users, the Snapdragon SoC-805 is not 64-bit capable and probably also less strongly benefit from similar improvements in the upcoming OS version, Android L. Moreover revealed already in the AnTuTu benchmark of Galaxy Note 4 that the Exynos 5433 SoC even without 64 bit optimization leaves the competition from Qualcomm in performance behind him. We can assume, therefore, is that Samsung does not have enough capacity, the Exynos 5433 to obstruct global and to potential buyers of the Galaxy Note 4 with Qualcomm CPU does not deter, completely refrained from referencing the somewhat zukunftssichereren 64-bit compatibility.
