Snapdragon 8xx 7xx 6xx what’s the really world difference?

[mrchow19910319]

What’s the real world performance difference between these chips. I think that benchmarks do not reflect the real performance of these chips. 

 

Also so if I don’t game at all , just reddit , web browsing , normal usage which chip is “good enough”?

It really depends on what device you're using them with. If the manufacturer did a decent job with their customization of Android, you'd probably be fine with even a 6xx level of SoC (look at the Pixel 3a, google did a solid job on the software side and it performs fine). Modern 6xx SoC's perform like a Snapdragon 835 from 2 years ago, which still holds up pretty well compared to the snapdragon 855 in real world performance. As a quote from Anandtech's Pixel 3a review:

Overall I was very satisfied with the performance of the Pixel 3a XL. It was extremely snappy in everyday usage, and if all you do on a smartphone is social media-like activity, then you’d be hard to press to find any differences between the 3a and other flagship devices.

 

Where the Pixel 3a more notably fell behind in was web browsing and loading of heavier pages. Here it was evident that there is indeed quite a generational performance gap and the mid-range SoC isn’t quite able to give the same experience.

 

One thing to note and again we can’t accurately measure with existing tools is the storage performance of the eMMC module of the phone. I did notice quite significantly slower installation speeds compared to newer phones. It’s not a total deal-breaker as some eMMC implementations of years past, but again it’s a compromise Google had to make to reduce the costs of the phone.

In terms of performance, everyday usage and CPU bound tasks perform very well thanks to the Snapdragon 670. The chipset performs at around the level of a Snapdragon 835, which while isn’t the best experience by now, it’s still extremely respectable.

 

Google’s choice of going with eMMC isn’t quite a dramatic as one would think, thanks to the filesystem optimisations and relatively good quality NAND, there’s only limited scenarios where the downgrade is noticeable. Still, yes it’s a tad slower on application installations, however I do find it as a reasonable compromise.

I'd also argue that there's a lot of other factors you should look at, e.g. amount of RAM and storage type (usually UFS storage is going to be a fair bit better then eMMC and result in quicker application load and install times).

 

So you'd mostly be fine with a 6xx or 7xx device as long as the software isn't too bloated. As an owner of a snapdragon 835 Pixel 2 XL, who's SoC has similar CPU performance to modern 6xx and 7xx SoCs, it mostly is still very snappy, and only occasionally do I encounter small bits of slowness. Something with an 8xx will be a little better, but the difference will be small

I own a SD821 device with LineageOS. Speed is quite fine. Photo editing in Lightroom isn't appreciably slower than on my desktop either (though Mobile Lightroom may actually be using the GPU compared to PC). The GPU of even (within reason) older 8xx SD chips tend to exceed newer 6xx and 7xx chips by a fair margin as well, though for 99% of stuff, this is hardly relevant.

 

My complaints about my phone is entirely unrelated to the SoC. Really hate my display when the dynamic contrast is throwing a hissy fit, for example.
