X20 with A72 is more efficient than SD625. A72 is efficient core while A53 in SD625 is slow core. So what happen is SD625 is using 14nm process. So its more power saving because it is slow.

SD625 take 10 minutes to do a task while X20 use 5 minutes.

Although SD625 is power saving, but because it is slow, X20 more than make the power saving in SD625.

In the end, both Note 4 X20 and Note 4X SD625 will last 1 day until you charge. Basically whether you want slow phone or fast phone, you decide.

I m already invested on X20 rather than SD625 due to performances.

Good choice.

How's the camera performance compared to Redmi Note 3?

Camera output are much improved compare to RN3, based on my personal opinion.

By saying 10 mins and 5 mins comparison is not entirely true my friend. Probably spec sheet u can say that.
For me is more like a 10 and 8.5 mins differences.
Users experience is all that matters. I am having 625 version and compared to my friend x20 . The speed of opening any apps or games is just slower by 10% plus minus. It won't even be noticeable unless you put side by side. The performance margin is not big.
My personal reference of soc is always SD as I think it would last slot more longer. 3 years min. My 2 cents. Haha

Actually X20 will last longer than SD625 because faster processor will last longer.

The reason why last time SD is last longer because SD is faster than MTK.

But this time, MTK is fast than SD by 50%. So I'm sure MTK will last longer than SD.

SD625 is A53 core. Very inefficient core that will slow to a crawl when the need for speed is there.
For MTK, when you need the speed, A72, will come in and boast the performance by 50% or more.

MTK have 3 cluster:-
A72
A53 Medium performance
A53 Low power

WHen opening app, probably use A53 medium performance already win SD625 by 10%.

If you need more extreme processing power, A72 will come in and boast speed. So 10minutes reduced to 5minutes is possible.

please use benchmark results to explain this. Cause just saying 10min vs 5min vs 8.5 min is a bit misleading. Also the GPU in SD is more efficient than MTK.

I would personally go for SD only because Mediatek does not release their source code to public. That means hard to find third party support for rom like cynogen, lineage and so on.

Plus comparing Soc to SoC, SD is more optimized. Previously, for Redmi Note 3 Helio X10 vs SD650. Performance and battery is still better on SD650.

You can't compare (X20 vs SD625) with (X10 vs SD650). You actually can, but the story is reverse. X20 is way way better than SD625.

X20 is 50% better than SD625 in terms of efficiency and performance in benchmark.
AnTuTu:-
X20 - 90k
SD625 - 60k

You're very uninformed if you still choose SD over MTK.

Not everyone flash custom ROM. Therefore, source code not important.

Again user experience is all is matters. Dude u can compare whatever spec you can based on paper. When put to use you will know the difference.
On paper x20 definitely a win but normal usage wise I felt the same. Like I said before hand I compare both mine sd625 and my friend's x20 the difference is very small in terms of loading speed.

Based on the specs from http://www.gsmarena.com

Mediatek version
- has Bluetooth v4.2
- supports wireless ac

Snapdragon version
- has Bluetooth v4.1
- does not support wireless ac

Loading does not tax processor a lot. Wait till you do more intense workload.

X20 is flagship processor
SD625 is low mid-end processor

Please tell me what is intense load, is gaming consider? Like running mobile legend or Pokemon? If yes nope I don't see a vast difference at all.

You are giving me all the paper spec again I believe both the thing u mention won't affect your daily usage and there are tentatively no difference .

And btw I am connecting my 5ghz wifi via basis router. Does my phone support wireless ac? Or just wireles-N . Anyway it don't matter unless your internet speed is 1gb.

There's a difference between normal and Performance mode eg when loading heavy 3D games, cad drawings.. on mtk. Other than that, not much difference except battery depletion quicker on Performance mode obviously.

Interesting...4x win over 4...

This 4x lost in apps opening...win in memory/multitasking...
