Exynos is a processor brand designed and developed by Samsung Electronics based on the ARM architecture. It was launched in February 2011. Exynos is a combination of two Greek words: Exypnos and Prasinos, which stand for “smart” and “environmental protection” respectively. Exynos series processors are mainly used in mobile terminals such as smart phones and tablet computers. On July 13, 2018, the official website of Samsung semiconductor Exynos was launched.
For Samsung, its self-developed CPU not only can’t give up, but it also continues to be entrusted with important tasks. This is the driving force for them to continue to fight for and compete with Apple. According to the latest news from the upstream supply chain, since TSMC has priority over Apple, Qualcomm will continue to cooperate with Samsung for the sake of safety, and both flagship CPUs will use Samsung’s 4nm process. It was reported not long ago that Samsung will use its 4nm technology to mass-produce the next-generation Snapdragon X65 5G modem in Snapdragon, so only this partnership can prove that Snapdragon 895 will be manufactured on the same node. In addition, it is said that Qualcomm paid Samsung US$850 million for the mass production of Snapdragon 888 earlier, so they may have reached an agreement at the moment.
A few days ago, foreign media exposed the relevant information of Qualcomm’s next-generation flagship SoC SM8450, which is said to be officially unveiled at the end of this year.
According to reports, the internal code name of SM8450 is Waipio, which is the name of the Waipio Valley on the north side of the Big Island of Hawaii. It continues Qualcomm’s tradition of using Hawaiian place names as the code name of its flagship chip, and its final consumer-oriented model is Snapdragon. 985.
In terms of specifications, the SM8450 will be built on a 4nm process, the CPU will use the Kryo 780 based on the ARMv9 instruction set, and the GPU will be the Adreno 730 with a new architecture, but the performance improvement is still unclear. The integrated baseband is the Snapdragon X65, which still takes all millimeter wave and frequency bands below 6GHz.
As for which foundry the 4nm process used is from, there are still divergent opinions. Although netizens hope that TSMC can manufacture the Snapdragon 895, because Samsung’s 5nm process is really not excellent, but from the current situation, The odds of Samsung foundry are greater.
At the same time, Dr. Inyup Kang, president of Samsung’s semiconductor LSI business, also revealed that the next-generation mobile GPU jointly created by Samsung and AMD will be used in Samsung’s next flagship product. The same semiconductor giants, what surprises will these two companies bring us? According to the news, Exynos 2200 will be equipped with a brand new GPU-built on AMD RDNA architecture, and has 1 Cortex-X1 super core, 3 Cortex-A78 large core, 4 Cortex-A55 small cores.
RDNA2 is the latest graphics architecture of Team Red, and it is also used in AMD’s new Radeon 6000 series graphics cards, and even PS5 and Xbox Series S/X GPUs. In the keynote speech, it was also announced that “AMD has been cooperating with industry leader Samsung for many years to accelerate graphics innovation in the mobile market.
In terms of performance, compared with the previous generation Exynos 2100, this processor will have a 25% increase in CPU performance and a 2.5 times increase in GPU performance, which is expected to surpass the Apple A14 bionic chip.
Under normal circumstances, Samsung products equipped with Snapdragon processors equipped with Qualcomm platforms are more favored by the market. This is because Samsung’s previous processors adopted a self-developed CPU architecture, but the problems of heat generation and power consumption cannot be optimized for a long time. , Has been widely complained by users, and even caused the reputation of their products to become worse and worse. However, it has improved in recent years. Samsung abandoned its self-developed CPU architecture and permanently closed its CPU core R&D department. Later CPUs also adopted the mature ARM architecture. In terms of GPU, this time we have cooperated with AMD again, and power consumption and performance should be guaranteed.
Su Zifeng said that the Exynos mobile phone chip that Samsung is cooperating with is sure to adopt the RDNA 2 architecture, which greatly improves GPU graphics performance, and even supports ray tracing, VRS variable update shading rate and other technologies. These top Display adapters will have technologies that will Attacking the mobile phone platform, detailed chip specifications and functions will be disclosed by Samsung in the future.
As the world’s only manufacturer with independent design and independent production of semiconductor chips, Samsung is obviously more eager to join the battle for 5nm chips.
Speaking of 5nm first, Exynos 1080 is Samsung’s first flagship mobile processor using the most advanced 5nm EUV FinFET process in the industry. Compared with Samsung’s 7nm process, Samsung’s 5nm process has increased the number of transistors by more than 80%. Bring stronger performance and lower power consumption. In addition, Exynos 1080’s EUV (Extreme Ultraviolet Lithography) has a 14% increase in performance and a 30% reduction in power consumption compared with 8nm LPP (mature low power consumption). Compared with 7nm DUV (Deep Ultraviolet Lithography), the performance has increased by 7 %, the power consumption is reduced by 18%.
The advanced level of the process is one of the important basis for judging whether a chip is a flagship, and another important basis for judging is the architecture. Like the previous generation of Exynos 980, Exynos 1080 chose the ARM public version solution, and the A78 was first released (for example, last year’s Exynos 980 also first released A77).
Samsung announced the new Exynos 2100 flagship chip again in the new year of 2021. This chip is also the fifth 5nm process chip after Apple A14, Kirin 9000, Qualcomm Snapdragon 888, and Exynos 1080. According to Samsung, the Rxynos 2100 uses Samsung’s 5nm EVU process. The improvement of the process allows the performance to be increased by 10% compared with the previous generation, and the power consumption is reduced by 20%.
In terms of network, Exynos 2100 also supports Sub-6GHz and millimeter wave 5G. The fastest download speed under Sub-6GHz network is 5.1Gbps, and millimeter wave can reach 7.35Gbps. At present, Exynos 2100 has begun mass production, and there is a great probability that it will appear on Galaxy S21 products in the future.
The performance of Exynos chips in the past has always been slightly inferior to that of Qualcomm’s Snapdragon in the same period. Through cooperation with AMD, the main hope is to improve the performance of mobile GPUs in order to provide players with a stronger gaming and audio-visual experience. It may also imply the performance of the next generation of Samsung’s flagship mobile phones. Functional direction.
According to the latest news from the supply chain, Qualcomm will continue to cooperate with Samsung, and both flagship CPUs will use Samsung’s 4nm process.
It is reported that the biggest highlight of Samsung Exynos 2200 may be the GPU part, AMD RDNA2 is integrated into it, and the performance is worth looking forward to. Samsung’s next-generation flagship SoC will be equipped with custom graphics IP provided by AMD, supporting ray tracing and VRS variable shading rate.
