You might know that every time Samsung makes a new flagship smartphone. They create two versions of Samsung Galaxy S20 128 GB, one powered by an Exynos chip and one powered by a Qualcomm Snapdragon chip, and on the face of it who cares but if you spend some time with both of these versions of galaxy s 20 ultras, you will have to think that the difference is so big that the Snapdragon version almost feels like a different smartphone before.
APP RUNNING SPEED
For example performance, there are so many tests of power than just seeing how fast apps open like when you run antutu on both and the Snapdragon is just way ahead of a 550 thousand versus 500 thousand it’s almost a 10% jump. That’s half a generational leap of performance.
You think that there is a big gap then it gets so much bigger see after running antutu once you decide to run it several more times without any break to see if either chip would overheat and yes after the second run this Snapdragon chip was at 40 degrees Celsius which is good after the third run in jump to 42 and actually after the final one it went down to 39. This Exynos after just two runs of the benchmark it was at 59 degrees, after run 3 it had managed to somewhat control that temperature it brought it out to 53, that last run had pushed it to 66 degrees that is not a cool temperature but ok finally the chip gets hotter, that’s not something you’re going to feel directly but what it translates to, is thermal throttling the Exynos starts dialing its performance back when it gets hot and because it gets hot so quickly it’s a problem so while the Snapdragon score fell from around 550,000 to about 545,000 over the course of these benchmarks the Exynos tanked falling from about 500,000 to around 450,000, so you’re now looking at effectively a 20% gap in performance and it gets even worse.
First, if you take a look at the performance breakdown. You can see that while Samsung’s CPU is behind right from the get-go the graphics or GPU is actually on par but this is what’s getting throttled as the temperature starts to rise the graphics performance is falling from nearly 22,000 to 15,000 but it’s ok that’s a synthetic benchmark, would an average user notice a gap in performance? well yes and no, if you look at this like for the most part of things happen out of pretty similar speed on both flicking through home screens loading up applications and so on. You probably couldn’t tell the difference, where you can though is in two specific use cases number one being prolonged gaming for short sessions. It didn’t seem to matter what game you played both phones just flew through it as you kind of expect for a firm that has ultra in its name. The issue with Exynos only started to come in with prolonged sessions so after you will carry this on for about an hour and then jumped to another heavy game. That’s when you feel it this is a resource-intensive game and the Exynos just started to bottle it, you could almost feel the chipset screaming on the inside and the frame rate tanked to something like 15 frames per second moving back to the Qualcomm no such issue it was just 60 frames per second locked the second difference you will see super minor.
In the camera UI for example shifting between the lenses is both smoother and faster on a snapdragon. Again this could improve in an update and speaking of cameras the snapdragon even takes better photos to which you might be thinking, how is that even possible? they have the exact same camera and they do. The difference between Exynos and Snapdragon it’s not just the CPU it’s the graphics. It’s the modem and irrelevant to this case the image signal processors. Well, that’s a brief performance comparison between Snapdragon and Exynos.
