The 2019 smartphones are coming up with more power and speed packed up in a more compact device. There are so many processors today that it becomes challenging for the buyer to decide which smartphone will be the best according to the requirements. Processors play a significant role in the performance of a smartphone.
Here, we have compared the processors, which commonly power mid to high range smartphones based on some essential aspects.
Fabrication process
While Snapdragon 660 and Exynos 7904 still sport a 64 bit – 14nm CPU architecture, Snapdragon 675 wins this race by a considerable margin on paper as it uses a 64 bit – 11nm CPU architecture. When the fabrication process is smaller, it can fit more transistors, and thus, we can experience better and more efficient performance.
CPU
We can see two different types of cores in the Exynos 7904 processor: Cortex-A73/-A53 CPUs. Samsung has started using octa-core CPUs, which give a much-optimised performance. Cortex CPUs are not generally seen on Samsung processors, but Samsung has decided to implement these in their newer processors by getting rid of the old Moongoose CPU cores.
On the other hand, Snapdragon processors also use octa-core CPUs, but instead of Cortex, they use Qualcomm Kryo CPU cores. Snapdragon 660 uses Qualcomm Kryo 260, and Snapdragon 675 uses Qualcomm Kryo 460, which is a much-advanced version of the previous one. Qualcomm cores are considered to be more optimised and better-performing CPUs than Cortex. Snapdragon 675 again wins the competition because of its more efficient and fast CPU.

GPU and Storage
In terms of GPU, Snapdragon 675 takes a giant leap over the other two processors. It uses Adreno 612, which is much smoother than Adreno 512, used in Snapdragon 660. Exynos lags as ARM Mali-G71 MP2 performs slightly less efficiently than Adreno 512.
Exynos can be slightly superior to the Snapdragon as the storage is better optimised as far as storage is concerned, and it provides better reading and writing speeds.
Camera and Connectivity
Snapdragon 675 wins the camera and connectivity segment too. It supports up to 16 MP dual camera and up to 25 MP single camera and has the fastest LTE connectivity amongst the three. Snapdragon 660 is the first runner up with Exynos 7904 still maintaining the last position.
Charging
Exynos 7904 supports the essential adaptive charging while Snapdragon 660 supports Quick Charge 4.0, and Snapdragon 675 supports Quick Charge 4.0+, which makes it the fastest charging processor amongst the three.
Benchmark scores
Snapdragon 675 leads the benchmark table with a fantastic score of 174,402 points (on Samsung Galaxy M40), with Snapdragon 660 securing the second position having 135,068 points (on Redmi Note 7) and Exynos 7904 at the third position having a score of 108,712 points (on Samsung Galaxy M20).

Very nice blog on Exynos 7904 vs Snapdragon 675 vs Snapdragon 660. Thank you for such an informative article. And I fully agree with your statement that which smartphone will be the best. Well, what I have observed Snapdragon 660 is one of the best processors as it enhances the power efficiency and thus it’s one of the most powerful mid-range processors in the company’s 600-series.
Thank you for your comment Priyanka!
I completely agree with you on this, Snapdragon 660 is undoubtedly one of the most powerful mid-range processors. Qualcomm has much more to offer. Let’s see which processors they come up with in future.
