Based on Intel’s 14nm FinFET process technology, SC9853I features 1.8GHz 64-bit octa-core Intel Airmont microarchitecture and Mali-T820 MP2 GPU. As for its modem, SC9853I supports LTE (Long-Term Evolution) Cat-7 downlink and Cat-13 uplink for 5-mode communication standard (TD-LTE/FDD-LTE/TD-SCDMA/WCDMA/GSM), which can reach downlink speeds of 300Mbps and uplink speeds of up to 150Mpbs to achieve a true 4G+ on-line surfing experience.

In terms of its parameters, SC9853I is quite competitive in the mid-range market. At Spreadtrum’s Global Partners Conference 2017, Spreadtrum pointed out that SC9853I SoC, although targeting at the mid-range and entry-level phone, has the flagship performance.

In order to illustrate SC9853I’s real performance, a comparison analysis is made among Spreadtrum SC9853I, Qualcomm Snapdragon 835, Huawei Kirin 970 and MTK Helio P23.

Because these SoCs have huge difference in CPU and GPU, the comparison is mainly focused on their modem performance in terms of download speed and voice calling performance.

Researchers tested the above SoCs by downloading 800+ GB files and making 3000+ minutes voice calls and the test results are as follows:

1. Download Speed

In low-speed driving, SC9853I’s download speed is close to Kirin 970 and Snapdragon 835; in high- speed driving, SC9853I’s download speed is higher than the other three SoCs.

Overall, the average download speed of SC9853I is as good as other flagship SoCs.

2. Voice Calling Performance

In high-speed driving, the average voice calling performance of SC9853I is better than Snapdragon 835 and Helio P23 by a long shot, equivalent to Kirin 970. The HD voice percentage for SC9853I, however, has room for improvement.

In low-speed driving, SC9853I’s average performance is similar to Helio P23, lower than Kirin 970 but superior than Snapdragon 835. Meanwhile, SC9853I’s HD voice percentage is lower than Helio P23 and Kirin 970 but superior than Snapdragon 835.

In conclusion, SC9853I’s performance is good enough to match a flagship SoC in terms of modem performance. Sources show that SC9853I has adopted the latest V2 architecture and made full-scale optimizations on radio frequency and baseband algorithms, which greatly improve its mobile communication performance no matter you are working, shopping or driving.

    Great breakdown in broad detail.

    Our Nigerian brethren hardly check the processor types nor even performance for that matter.

    First is the Camera, second battery, third ram size, 4th other esthetics.

    The high tech aspect hasn’t fully dawned on us and I believe to many, ignorance is bliss when it pertains to this. Lol.

    I admire the dedication bro. Kudos

    This article is absolutely lovely, you simply break it down for us to understand, job well done. This is what most of us don’t know about our Smartphones, what comes to some people’s minds when getting a phone are the Big screen size, good camera, big battery capacity, some don’t even care about “RAM” size, and they will later complain about their phones been Slow and getting hot. That is why every phone users should see this article.
