Today Samsung Semiconductor released the Exynos 8890 eight core processor in South Korea. This is Samsung's second SoC based on the 14nm FinFET process. Different from Exynos 7420, this Exynos 8890 is a true whole chip solution, integrating CPU/GPU/ISP and the latest LTE Cat.12/13 baseband. Samsung's first 64 bit ARMv8 architecture CPU is used, which is also the Mongoose architecture rumored before.
The CPU part is composed of 4-core mongoose+4-core A53, which strengthens the multi-core scheduling capability, enhances the multi task/process performance, and can better improve the utilization efficiency of 8-core.
Although Samsung did not mention the GPU, it is Mali-T880 The specification of MP12 is extremely furious. It has 12 graphics cores and hits Mali-T880 MP4 of Kirin 950. Officially, this is to prepare for immersive 3D games and virtual reality experience.

The baseband also catches up with the baseband crazy Qualcomm. The downlink Cat.12 has a maximum download speed of 600Mbps; Uplink Cat.13, the maximum upload speed can reach 150Mbps (the download speed is the same as that of domestic 4G...), which is the same as that of Snapdragon 820. Samsung said Exynos 8890 plans to start mass production at the end of 2015.
performance analysis
The performance of the official Exynos 8890 is 30% higher than that of the 7420, and the efficiency ratio is 10% higher. Note that the official text is power efficiency rather than power consumption. Considering the performance improvement, the actual power consumption of the CPU should be higher than that of the 7420.
With the Geekbench score running information previously exposed on the Internet, the Exynos 8890 (i.e. Exynos M1) scored 2294 for single threads and 6908 for multiple threads at the preset frequency of 2.3GHz. Compared with Apple A9, single thread is 1.1 times weaker and multi thread is 1.57 times stronger. It has maintained the previous situation of weak single core and strong multi-core Android platform.
However, the GPU part is more advanced. Compared with the Mali-T760 MP8 of the 7420, the GPU architecture is upgraded with four more cores. Even if Samsung lets it run low frequency, the performance is also very impressive. However, the author is more concerned about how Samsung controls its power consumption. Even if the manufacturing process is slightly improved and runs at low frequency, there will be 50% more cores. Once it runs at full speed, the power consumption and heating will be exaggerated.
The power consumption of CPU and GPU is likely to increase. In addition, Samsung baseband has made a great leap forward this time. The power consumption may be difficult to control. The three are mixed together, which makes the author worried about its heating and power consumption.

From the information leaked now, the Exynos 8890 is compared with the Qualcomm 820/Kirin 950 of the same generation. CPU part:
Exynos 8890 temporarily leads with a single core close to 2300 and a multi-core close to 7000;
The Kirin 950 has a single core of 1700 and a multi-core of 6300;
The Snapdragon 820 has a single core 1900 and a multi-core 4000 points.
GPU part:
The strongest Android platform of the previous generation is Qualcomm Adreno430, while Adreno530 on 820 claims to be 40% higher than that of the previous generation.
Samsung and Kirin are both Mali-T880, but Kirin 950 is Mali-T880MP4. The number of cores is much less than Samsung's violent Mali-T880MP12, and the performance is not very good.
Samsung's T880MP12 frequency is unknown. If it can maintain the frequency close to that of the previous generation, 50% of the core number growth and architecture upgrade will definitely bring more than 50% of the increase. It can compete with Adreno530, and perhaps win a small victory.
Despite the power consumption problem that cannot be judged at present, Samsung's SoC is likely to continue to be the strongest name of Android, and this generation also has the strongest baseband of Qualcomm's peers. However, like the Samsung Shannon baseband this year, the Exynos 8890 baseband is estimated not to support the CDMA network of Telecom
Time node
It is worth noting that Exynos 8890 announced that the mass production time was at the end of this year. The Qualcomm 820 and Kirin 950, which were released several days earlier than Exynos 8890, did not seem to mention their own mass production time. The S7 of the next year may be released in advance in March or March, as rumors have said.
In terms of Snapdragon 820, no manufacturer has come out to compete for its first round. However, there was a rumor yesterday that the SoC carried by Samsung S7 would be split half and half between 820 and Exynos 8890. The mass production time of Snapdragon 820 should not be too much behind Exynos 8890.
Kirin 950 is likely to be launched by Mate8, which is rumored to be released on November 26. The Kirin 950 will be the first to come out, but if Huawei learns from Xiaomi's initial habit of PPT, the machine equipped with the Kirin 950 may wait until the beginning of 2016.
