Samsung will use ARM Cortex-X1 for their upcoming chip, Exynos 2100

Online tipster, IceUniverse has leaked that Samsung Exynos 2100 will use ARM Cortex-X1. Further, I will be analyzing the potential performance of Exynos 2100 and how it will fare against Snapdragon 875.


Samsung’s Exynos SoC (System on Chip) has been struggling to match the performance and efficiency of Qualcomm’s Snapdragon SoCs. Their last chip Exynos 990 was a disaster with heat, performance, battery life, and camera problems.

Tech Insider, IceUniverse has strong evidence that Exynos 2100 will use ARM Cortex-X1 core. These are performance-enhanced cores and are the best cores that ARM has to offer right now. They offer much better single-core performance and Machine Learning performance over ARM Cortex-77(Used in the Snapdragon 865). For the core configuration, they will be using at least 1 ARM Cortex-X1 Core, 3 ARM Cortex A-78 cores, and 4 ARM Cortex A-55 Cores.

Both the Exynos 2100 and Snapdragon will be built using Samsung’s 5nm process. Scotten Jones of semi-wiki, who maintains the transistor density for different processes, has shown with his calculations that Samsung’s 5nm offers 1.33x density improvement over Samsung’s 7nm process. The die size of both Exynos 2100 and Snapdragon 875 seems to be the same.

There were speculations that the GPU(Graphics processing unit ) of the Exynos will be supercharged due to Samsung’s partnership with AMD’s Radeon Group. However, this doesn’t seem to be the case with Exynos 2100 where AMD’s GPU and architecture seem to be missing in Action. So, people will have to wait some more and Exynos fans will have to work with the mediocre Mali GPU for now.

A mysterious user claims to have the GeekBench result of both the SoCs. He claims to have two variants of Samsung Galaxy S21 one containing Samsung Exynos 2100 and the other one Snapdragon 875.

The benchmarks if true give a great insight as to what we can expect for the performance of both the SoCs. The Single-Core and Multi-Core performance of Exynos is better than Snapdragon. This is very weird. Both the SoC should have the same performance in GeekBench, however, the above results show something else. 100 points in GeekBench can’t be neglected as a margin of error. It could also be that the SoC being run on a Samsung smartphone is better optimized for Exynos now and further optimization for Qualcomm Snapdragon 875 can easily close the gap at launch. However, I would say you should take this leak with a grain of salt, as there has not been any GeekBench listing to prove it completely.

The core configuration matches up with the Snapdragon 875, so you can expect the same CPU, battery life, and thermal performance as Snapdragon. Though GPU and Camera performance analysis is on the fence, as the Exynos will still use Mali GPU and NPU(Neural Processing Unit) cores for camera processing. However, unlikely that both the cores will be able to match Apple Bionic A14 performance.
