64bit roms for RedMi 2 - Xiaomi Redmi 2 Questions & Answers

Hi, are there any 64 bit rom for our RedMi 2? The Moto G 3rd gen has native 64bit system, as well as the most of chinese phones equipped with ARMv8 CPUs (Snap x10, MTK67xx, etc with Cortex A53 or A57 cores).

Probably never, even Xiaomi hasn't released a 64 bit rom, and also didn't release the 5.1 kernel source code (and probably won't for a year or so)

My Find 5 has Snapdragon 600 !

Just got my Find 5 (few months old with CM 10.1 installed) and according to "CPU Identifier" app, it has a Snapdragon 600 (8064T) processor, a quick Google reveals that Oppo released a Find 5TD in China a few months back with the 600 clocking @ 1.7 Ghz.
Antutu says my max clock speed is 1.512 Ghz though.
Maybe "CPU Indentifier" is telling lies or maybe CM 10 is holding back my processor speed cos it thinks its a Snapdragon S4.
If it was CPU z then it will say that. Same thing happened on my nexus 4.
But I am told some of the oppo find 5s where updated
Sent from that one guy with the cool phone
If I helped you hit that Thanks button!
Yes, this is possible, due the fact that OPPO has upgraded soms Find 5's. But I thought they where all set on 1.5Ghz, if you want to can install a custom kernel and clock it right to 1.7Ghz.
Just installed CPU Identifier and I've got also a Snapdragon 600! AWESOME!
where did you guys buy your oppo find 5's from? I read that they refreshed it with the snapdragon, but all the places that sell it still list the old specs

Actually the updated Find 5 has the same processor as the Nexus 7 (2013), it's an underclocked Snapdragon 600, but on paper it's a S4 Pro Krait 300.
really ? one more thread about it ..... no and no.
Oppo Find 5 is a APQ8064 SoC , which is a Snapdragon S4 Pro
Its not one of those :
APQ8064T
APQ8064AB
APQ8064M
Find5 SoC is the same as Sony Xperia Z. All about the S600 SoC in a find5 is just rumours and have never been proven that it was correct

Mine has a Snapdragon S4 @ 1.51. I use cpu-z.
With some kernels you should go up to 1.9GHz... but IMHO OC on these devices is useless.

Snapdragon 400 Cuad vs Snapdragon S4 Pro

Simple question, I purchased a Moto G GPE and its on its way but i have the curiosity about how the SOC Snapdragon 400 Cuad Core compares to something like the S4 Pro that was in the Nexus 4 which ran great. I know its a newer chip but i havent found any real evidence whether the architecture is superior or inferior to the S4 Pro since it was a flagship chip but the 400 is budget. Anyone has any insight on this? Thanks.
best way to compare the two.

Snapdragon 400 is positioned more like S4 Plus, not Pro. As in marketing positioning.
Speaking in technical terms however, those two SoCs have a completely differnet architecture. S4 Plus always has Krait cores, while our S400 has Cortex-A7 cores, which is generally somewhat slower than Krait, partially because Krait is an Out-of-Order architecture, while Cortex-A7 is In-Order.
In terms of cores S4 Plus always had two cores (up to 1,5 GHz), while our S400 has four cores @ 1,2 GHz.
Now go figure what´s faster. I´d personally prefer two Kraits
Note: Qualcom had really messed up the naming in S400 series as the chips can contain either two Krait cores or four Cortex-A7 cores. Don´t get me wrong, Cortex-A7 is a great architecture , mostly because its performance/power consumption ratio, but the SoCs containg those cores should have been labeled as Snapdragon 350 or something like that.

[Leak] Early benchmark of future ARM chip...

Hi guys
One of my friends today just receive some unknown sample product (He's working on a labs)
+Snap 810 @2,2GHz (development board)
+Tegra K1 64bit Denver Dual Core @2,5 GHz
+Tegra K1 32 bit Quadcore
Benchmark result of Snap 810 vs everything (early beta kernel complied with GCC4.9 and benchmark in 64bit if available)
Single core Snap 810 vs [email protected] 2,5Ghz: increase 25% in single thread and 50% Multithread
+vs Tegra K1 64bit: 28% loss in single thread and 50% faster MultiThread
+vs Tegra K1 32bit: 12% faster in single thread and 34,5% faster in Multithread (2 thread vs 8 thread )
+vs Apple A7: 13,5% loss in singlethread and 86,5% faster in multithread (Same, 2 thread vs 8...)
+vs Apple A8: 20% loss in singlethread and 71% faster in multithread (same thing, 2 vs 8)
And Snap 805 is = with Tegra K1 Dual Core 64bit in perf
Also I have benchmark of Adreno 430(driver and chip still beta): faster than 30% vs Adreno 420, more than 90% faster than Apple A7 (PowerVR G6430) but loss 8-10% vs Tegra K1
Also more breaking news: Samsung Note 4 Exynos version is using Samsung CMC221 modem, Samsung have plan to use Intel XMM7260 with 22 band LTE cat 6 but drop it and using own-product with 7 band lte and cat 4
And Exynos version this time is more powerful than Snap
P/S: All thing I mentioned is confidental and NO PICTURE OF THEM (if they found out we leak them, we will get....)

Only quadcore cpu?

What is this, i read everywhere that the Tegra X1 i an octa core with 4x a57 and 4x a53 cpus, yet i received the console today and all apps report it as being octacore, only seeing/using the a57 cores and not the a53 cores. to all of it it seems like nviidia has changed their page so that it reflects the shield tv to be quadcore???
http://shield.nvidia.com/android-tv/shield-androidtv-vs-appletv-vs-roku-vs-firetv
are other people seeing this as well (for instance if you check with aida64 or with 3dmark), perhaps firmware blocked with new firmwares or is the hardware in the newer consoles actually inferior to the older ones?
I've only ever seen the Shield advertised as quad core even if the SoC is 8 core

Choosing SoC MTK 8127A vs PX 5 RK

Hello want to change my aunt and I am in big trouble
My choices are an Android device based on MTK 8127A from ATOTO but that come with 2 GB of RAM or a regular one based on PX 5 which come with 4 GB of RAM.
I understand that the MTK car goes devices are a little bit rare
So what to choose:
ATOTO with a MTK PROCESSOR and 2 GB of RAM, pretty good support and rom updates or a PX 5 ?
Which is faster and more stable?
Thank you

From what i have heard, MediaTek has better reputation than Rockchip. Which one is more stable / faster depends on how the SoC is integrated into the platform, how the Software Governers control the clock rate of the SoC. So this is difficult to answer strictly based on the SoC chip itself.
SoC Chip: MTK 8127A
Soc-based Quad-core 1.5Ghz Cortex A7 CPU
GPU ARM Mali-450 MP4 .
System Version: ATOTO AICE OS 9.4, which is developed & customized based on Android 6.0 Marshmallow OS;

but there are also :
PX6 ! devices (but it's news no more info a this moment) :
Android 8,1
CPUX6 RK3399
2 Core cortex A72 2ghz
4 Core Cortex A53 1.5ghz
RAM: SAMSUNG DDR3 4 GB
https://forum.xda-developers.com/an...-android-unit-cortex-a72-four-cortex-t3847427
And A72 Core is a lot better than A53, and A53 is a little bit better than the very old Cortex A7
I agree with @mum1989 that A72 and A53 CPU cores have much better specifications than the A7. If the applications you run on the head unit can take advantage of the ARMv8 instruction set or if the workload can be distributed across the cores, then PX6/PX6 SoC may well perform better than MTK8127A. On the other hand, in my day-to-day use of ATOTO A6 Pro which uses MTK8127A, I have never observed it to be slow or stutter or otherwise show signs that older A72 Core was limiting the end-user experience.
