Both Samsung Galaxy S6 and Galaxy S6 Edge are powered by the company's latest Exynos 7420 64-bit octa-core processor. This is the first mobile SoC build on a 14nm manufacturing process, and is 30-35% more efficient than most processors out in the market at the moment. Various benchmarks and performance of the two devices show that this is a true powerhouse of a processor. It remains to be seen if Samsung will deploy it in any additional devices by the end of the year, but that's highly likely. Samsung still has to release quite a few high-end products by the end of 2015, Galaxy Note 5 and the new Galaxy S tablets are good examples. The company will quite probably include this SoC in some of those devices, if not all of them, we'll see.
It seems like Samsung is cooking up a new SoC for the future. According to this new report, Samsung might opt for Cortex-A72 cores this time around, but develop a custom processor core. The aforementioned core is currently codenamed "Mongoose" according to the report, and will be built on a 14nm FinFET manufacturing process. ARMv8 architecture will also be a part of the picture, which basically means we're talking about a 64-bit architecture here, which is kind of logical at this point. The report also states that the Mongoose's maximum clock speed will be 2.3GHz. Another thing that was mentioned by the source, is the Geekbench 3 benchmark results for this processor. The Mongoose allegedly accounted for a single-core score of 2,200, which completely shatters the results of Exynos 7420 (1,495).
Keep in mind that this is just a rumors at this point, there's no proof that this processor actually exists, but the info seems somewhat legit though. Either way, this sounds really interesting. If this information is true, this processor will perform significantly better than the Exynos 7420, and it seems like Samsung's latest offering basically destroys every other mobile processor out there. We'll let you know as soon as we get some more information regarding "Mongoose", so stay tuned for that.
