After four generations of using custom Mongoose kernels designed by Samsung, but not making much impact, in 2019, many rumors said that the company had dissolved this chip design division. But not so the company’s Exynos chips stopped growing.
A few days ago, Samsung made a comeback with the introduction of its new Exynos 2100 chip for flagships of the year 2021. But unlike previous generations of processors, the Exynos 2100 uses Cortex cores. by ARM instead of using the company’s custom kernel. Not only that, but at the heart of the all-round Exynos 2100 changes is processing performance.
19% higher single-core CPU performance, 33% higher multi-core
For power-efficient and high-performance cores, the Exynos 2100 features 400MHz higher clock speeds than its Snapdragon equivalent. This would give Samsung’s processor a significant advantage in tasks that require CPU multithreading capabilities. The improved performance numbers clearly show Samsung’s new priority. The Exynos 2100 has 19% higher single-core performance compared to the previous generation, while multi-core performance is up to 33% higher.
Outstanding processing performance compared to previous generation
Not only that, the new X1 core in ARM’s original design offers even more performance. The clock speed reaches 2.9GHz, 60MHz higher than the competitor Snapdragon. Even if it’s a small difference, it does show Samsung’s preference in the new processor. Unlike other kernels, the Cortex-X1 core on new ARM processors allows a partner to order deeper editing requirements than usual, resulting in higher performance, as well as more features.
So, although the Exynos 2100’s ARM core architecture is similar to Qualcomm’s Snapdragon 888, it is the Cortex-X1 core that makes the difference between these two ARM-based processors.
A leap in GPU performance
The new GPU performance is up to 40% higher than the Exynos 990
Not only the CPU performance, the graphics power on the Exynos 2100 will also be improved by leaps and bounds when Samsung says its GPU performance is up to 40% higher than the previous generation.
How has Samsung been able to make such a huge leap in performance? The first is the use of a new graphics core Mali-G78MP14. Although its clock speed has not been disclosed, in theory, the Mali-G78 GPU has a performance-to-power level of about 10% better than the previous generation, the Mali-G77.
However, using the new 5nm chip process on the Exynos 2100 brings the remaining improvements to the new GPU, as it delivers up to 20% more power efficiency than the previous generation. The rest responsible for this long leap in performance is probably with the semiconductor chip designs, which help the GPU make better use of the new manufacturing process and the new graphics core.
Other components in the processor
In addition, the other processor components, including the NPU artificial intelligence processor and the ISP image processor, are all greatly improved in performance over the previous generation. With the addition of a processing core, as well as a higher energy efficiency level, the new NPU on the Exynos 2100 is nearly twice as efficient as the Exynos 990.
Meanwhile, with the new ISP and DSP image processor, Samsung says the Exynos 2100 is capable of supporting up to 200MP camera sensors. Moreover, the new chip also supports connection to 6 sensors to take pictures and process up to 4 of them simultaneously.
Without using a separate 5G modem, the 5G modem is now integrated directly into the Exynos 2100
One of the other small changes that Samsung brings to the Exynos 2100 is 5G connectivity. While Exynos 990 uses the Exynos 5123 discrete modem, on the Exynos 2100, this new generation connection is integrated directly into the processor. This design may not bring much change in speed or features, but it will certainly help significantly improve power consumption as well as save space for smartphone motherboards.
A series of major improvements in the performance and features of the Exynos 2100 over its predecessor show that this is the perfect “comeback” for Samsung on the mobile processor playground. The Exynos 2100 is the reason why the Galaxy S21 is more desirable when it is the first flagship to be equipped with this high-end processor. The outstanding performance improvements on the Exynos 2100 will keep many eager to see what new features they will bring to this year’s Galaxy S21.
