GPU, not really but in terms of CPU it's yes. Helio X20 had two more ARM Cortex A72 cores.

Redmi note 4 have global rom. i guess redmi 4 dont have global rom yet.

Initially, my idea was to get the RN4 as a spare phone.. but after my prev hp went kaput, it became my main phone. Lemme summarise what I like/dislike abt the phone:
+ latest mediatek chipset Helio X20
+ 3gb ram & 64gb rom (expandable via microSD)
+ big screen, minimum bezel
+ big battery 4100mAh
+ fast charge, lasts long (enough for 1 day work with full charge)
+ infrared (can use as remote, tried on my tv, a/cond, fan, etc)
+ notification light (selectable colours), also displayed when charging (red->yellow->green)
+ fingerprint (very fast response eg unlock phone)
- camera picture quality ok la
- cant find any pouch other than the cheap rm10 transparent tpu case at the moment
- 2pin charger (but i use my 3pin nokia 1020 charger)
- not official in msia, so warranty is by supplier

From what I compared online yes 899 is expensive, but I prefer walk in in case I ever need to claim the warranty. Thanks for the elaborate input, appreciate it.

I'm typing this on my gold RN4 and it's fantastic for the price. No case only SP installed. Not really digging SP I think may scrape it off and use it naked. Thoughts?

Good to hear the it performs daily for you. I'm sure it'll do a fine job for me.

GPS is excellent so far.

Almost opt for the Xiaomi Redmi 4 Prime with SD650 just now, but lack of global ROM is an instant turn off for me.

Although my only gripe is that the vibration when home/back/recent are pressed are quite strong even at lowest settings. in fact it caused an unpleasant vibrating noise, maybe it is caused by my SP?

Edit: downloading 8.0.4.0 as we speak. Painstakingly slow for some reason.
