First of all GHz don’t tell the whole story. It would be better if you could mention the SoC instead.
There are many starting from the entry levelto the premium flagship SoC that operate at 2.3 GHz. Yet their performance is drastically different.
Also, there is a lot more than just processor clocks that makes a phone fast.
The storage type and RAM plays important roles too!
Now, let’s assume you are talking about a midrange smartphone POCO X3 (Snapdragon 732G, UFS 2.1 storage, minimum of 6GB LPDDR4X ram). It is a fairly capable smartphone that is plenty powerful. So, in most cases it should be good enough for light and moderate users for 3 years.
However, how your smartphone will fair over a span of 3 years depending on what exactly you do with it.
If you are someone who likes to play the latest and greatest mobile games you might see frame drops and lags in games.
This is because each year more graphically demanding games are appearing on the playstore. Along with that games like CoD mobile and Genshin’s impact are getting heavier each day.
I used to play PUBG Mobile on my now 4 year old Redmi Note 4 that comes with the Snapdragon 625 (was fairly powerful for 2017 standards).
It used to play PUBG fine up until season 8 or 9. After that the game became too heavy for my poor phone to handle.
For most daily uses my redmi note 4 works okayish. But I am starting to see more lag every day.
So, to sum it all up there is a lot more to a fast phone that meets the eye.
If you want to buy a phone today here are a few key things (strictly based on performance) that you should look for —
Buy a good phone with a good SoC and good amount of LPDDR 4X ram (6 GB should be enough)
The phone should have a fast storage at least UFS 2.1, 2.2 or 3.0 or above (don’t buy any phone with emmc5 or 5.1 storage.
And lastly don’t just look at the processor clock speed. After all you are looking for a fast phone that lasts not a bare number crunching machine!
