- Snapdragon 865 for Samsung Galaxy S11 Could Be At Least 20 Percent Faster
The South Korean company has unveiled another system-on-chip, the Exynos 9825. Samsung is manufacturing the SoC in its own fabrication facilities with the 2nd generation 7nm process and EUV technology. It’s now possible for Samsung to fit more processors into the new chip, compared to the Exynos 9820 that uses 8nm process. The extra miniaturization allows the Exynos 9825 to consume up to 50 percent less power and it could have up to 30 percent improvement in performance. The 2nd generation 7nm chip manufacturing process revolves around the EUV (extreme-ultraviolet lithography) technology. With highly accurate computer-controlled ultraviolet beams, Samsung can etch silicon in finer details. With better precision, Samsung can add more transistors into the chip.
Samsung confirms that the Exynos 9825 still has the same basic design with the Exynos 9820, despite the much improved miniaturization process. It’s still an octa-core design with two Cortex-A75 cores for high-performance tasks, four low-power Cortex-A55 for less intensive tasks and two Samsung’s custom cores. The GPU is still the same, which is the ARM Mali-G76 MP12. However, the two Cortex-A75 cores and the GPU for the Exynos 9825 run faster, due to the improved miniaturization. A new addition is the NPU or Neural Processing Unit that enables AI technology for smartphone cameras. The AI technology is useful for accurately recognizing objects, learn user patterns and optimize photographs for better results. The NPU also includes the Augmented Reality feature.
There’s support for the UFS (Universal Flash Storage) 3.0, that uses less energy and twice the bandwidth, compared to the UFS 2.1. It could also withstand higher temperatures, because modern smartphones are getting hotter at full performance, due to more powerful processors. Another crucial component is the integrated 4G LTE-A Pro modem, which is fast enough for average smartphone users. If smartphone manufacturers want to add 5G capability, they could pair the Exynos 9825 with the Exynos 5100 5G modem, that supports sub-6GHz and mmW 5G airwaves.
