If you are thinking about CPU in the PC field, maybe you think Intel or AMD. These two companies produce almost every PC CPU.
But in mobile, It is a little different.
In the mobile sector, various companies manufacture their own APs.
For Example, Apple's A series, Samsung's Exynos, Huawei's Kirin and Qualcomm's Snapdragon.
Among them, Samsung announced a new Exynos , which is called Exynos 9820.
Compared with Exynos 9810, of course the Exynos 9820 has more powerful performance.
Typically, it was fabricated with an 8nm FinFET process, which was further refined when the 9810 was fabricated at 10nm.
Thanks to that, It can do more something.
It is an octa-core AP with two custom cores, two Cortex-A75 cores, and four Cortex-A55 cores.
Performance per single core (single core) has improved by about 20%, power efficiency has improved by 40%, and multicore by 15%.
It has also NPU for artificial intelligence calculations. This results in a 7x improvement in AI computation performance compared to 9810.
This is not to say that Apple has done a fair amount of performance on the A11 Bionic with a neural engine, and I can see that performance improvements have been made in the Exynos 9820 as well.
What is good when AI performance more powerful? If you ask, you can do various things using AI nowadays.
First, you can get a lot better performance when running apps that use Augmented Reality (AR) and Virtual Reality (VR).
For the second time, AI is applied to cameras. When the camera catches a subject, it automatically calculates the relationship with the surrounding environment so that the subject can be photographed more clearly or automatically finds the optimum value. With NPU , you can do it faster and more accurately.
It is good news for users because there are many things that can be done if AI operation is fast.
The communication speed theoretically supports the downloading speed of up to 2Gbps and uploading speed of 316Mbps.
Next is GPU. GPU is graphics performance.
The Exynos 9820 is equipped with the Mali G76 MP12 GPU.
we can understand that "Mali G76 MP12 GPU" is named 'Mali' and has 12-core GPU.
The performance is up to 40% better than before, 35% improvement in power consumption, 8K 30fps or 4K 150fps encoding, 10bit H.265 is also supported.
There are a lot of things that have improved, but again, it is quite unfortunate that the GPU is Mali.
Even though gaming performance is also important, but Mali is worse than Qualcomm Snapdragon's Adreno or its own GPU on Apple A Series.
Therefore, it is a very unsatisfactory part that the Mali GPU is mounted again.
It seems that Samsung has adopted the Mali GPU because they don't have skills ... Samsung have a good skills to make CPU but GPU is not maybe....
When you see upward picture, Exynos 9820 is many changed compared to Exynos 9810.
However, since the 9810 was already performing well, it is also true that it is difficult to differentiate by raising the performance that is even more visible.
This is because the performance of APs has been standardized upward. This is not uncommon when you consider that the iPhone 6s released three years ago is still quite capable.
The Exynos 9820 has also boosted performance, but at the same time, it has focused on additional performance.
Specially, Samsung is interested in AI computing ability. So that's why Exynos 9820 has NPU.
It is estimated that the Galaxy S10 will include more and more new features not available in the S9.
I am looking forward to seeing what extraordinary features will be included. Oh, of course, not like Anime emoji....
