Exynos

Since then, Samsung has used Exynos as a representative brand name of their SoC, based on Arm Cortex cores.

In 2017, Samsung launched their proprietary Arm ISA-based customized core designs, codenamed "Exynos M".

The driver code for the Exynos 4210 was made available in the Linux kernel[5] and support was added in version 3.2 in November 2011.

Samsung Exynos 5 Dual has been used in a 2015 prototype supercomputer,[11] while the end-product will use a chip meant for servers from another vendor.

[15] The SARC develop high-performance, low-power, complex CPU and System IP (Coherent Interconnect and memory controller) architectures and designs.

[17] After a three-year design cycle, SARC's first custom CPU core called the M1 was released in the Exynos 8890 in 2016.

[18] In 2017 the San Jose Advanced Computing Lab (ACL) was opened to continue custom GPU IP development.

In Hot Chips 2018, Samsung announced a new custom core named Exynos M3, codenamed Meerkat.

However, Samsung Galaxy S9 with Exynos 9810 was criticized in early period of their release due to the poor CPU core scheduler settings.

[23][24] On 1 October 2019, rumors emerged that Samsung had laid off their custom CPU core teams at SARC.

[33] The first SoC to use Radeon GPU were Exynos 2200, introduced in January 2022, with a custom Xclipse 920 based on AMD's RDNA 2 microarchitecture.

[34] In June 2021, Samsung hired engineers from AMD and Apple to form a new custom architecture team.

[205] However, the majority of people faced the issue after the 12 month warranty period, mostly starting 1.5 - 3 years after purchase.

Most users resorted to risky yet cheaper 3rd party repair that required re-soldering (also called reballing) the CPU & RAM PoP (Package on Package) which managed to solve issue according to dozens of user reports on said forums.
