This is also the only GPU that boasts 12 operating cores, making it a real beast, at least on paper. Samsung went with Mali-T880 MP12 which is a major step up over Mali-T760, and claims to be the most energy-efficient GPU out there right now. Qualcomm opted for the Adreno 530 unit for its Snapdragon 820 – one of the most powerful GPUs on mobile devices out there right now.
GPU is a major differentiator between the two variants of the Galaxy S7. This is even more significant because most real-world usage scenarios don’t rely on a single-core setup. Second, Antutu favors single core performance over multi-core results, and 820’s HC approach gives it an added edge there.

One, there’s a difference between a device benchmark and an SoC benchmark, so Antutu doesn’t tell the full story. However, take these benchmark results with a grain of salt, because there are certain facets to the Antutu test that are usually ignored. In Antutu’s official numbers from its v6 tool, Snapdragon 820 posts more impressive overall scores over the 8890 Exynos SoC. However, when you look at multi-core performance, that’s where the sheer power of the four Mongoose cores fully shines, taking an almost 30% leap over the Qualcomm processor. Thanks to its heterogeneous layout, Snapdragon 820 variant destroys its Exynos 8890 counterpart in single-core performance, and even edges past the current champion, Apple’s A9 chip from the iPhone 6s. By adopting this layout, Qualcomm has maximized the use of heterogeneous computing (HC) in Snapdragon 820, resulting in massive performance gains over last year’s Snapdragon 810 despite the latter’s octa-core setup.įor the Galaxy S7, these different approaches to processor layout translate to a major difference that we saw in the table above as well. If we look at the breakdown of the processor layout, we can see that the Kryo LP cores (1.7 GHz ones) have their own L2 cache, and the Kryo HP cores have their own L2 cache, with both of them separated by a large 元 cache cluster. While varying clock speeds is something that Snapdragon 820 borrows from big.LITTLE, that’s where the similarity ends, and the resulting setup is basically an asymmetrical 2×2 heterogeneous cluster. And that’s where the primary difference between Qualcomm’s approach and big.LITTLE architecture lies. Two of these spin at 2.15 GHz while the remaining two hum at a comfortable 1.7 GHz, resulting in a difference of merely ~450 MHz between the two. With Snapdragon 820, Qualcomm reverted to a quad-core setup, opting for almost identical custom CPU cores dubbed Kryo. The immensely powerful Mongoose cores are more than capable of outperforming even the toughest competition, but we’ll get to that later.
Hence, as you can see in the table above, Exynos 8890 has four Mongoose cores that handle the high-performance part, while the four Cortex-A53s humming at 1.6 GHz manage the low-power-consumption part of the processing capabilities.
Under big.LITTLE, an SoC is laid out in such a way that it gives a mix of low-power and high-performance CPU cores for varying workload needs.
With Exynos 8890, Samsung has followed the path of big.LITTLE architecture that ARM specified and that was mainstream last year. Why the shift? That has to do with how these microprocessors are laid out. However, do remember that Qualcomm went back to quad-core after having played with an octa-core setup with Snapdragon 810. Let’s take a look at the differences one by one.įrom the first look, it becomes evident that Snapdragon 820 and Exynos 8890 are different beasts one supports the traditional octa-core setup that became all the rage in 2015, while the other (on paper) seems to be dated quad-core setup. In comparison, even in Canada you’ll find an Exynos model over Snapdragon.īeyond this point, where we say Galaxy S7, that automatically refers to the larger S7 edge sibling as well, since the innards of both these devices are basically identical, whether it be the Snapdragon model or the Exynos one.įirst, let’s take a look at the differences at a high level before we delve into the details of these.įrom a summary perspective, it’s evident that the Snapdragon 820 variant is stronger in some areas while the Exynos 8890 tips the scale in others. This has to do with the inclusion of a CDMA radio on the Snapdragon SoC, making it the more favorable choice for these two markets. The Snapdragon 820 variant of the Galaxy S7 has been released officially in the US and China, while the rest of the world will receive an Exynos model.
