Quad core vs Octa core

Short Version:

So, this question is probably a simple one, but I'm not a developer / coder / claim anything about knowing how android OS's work. But, what are the benefits / disadvantages of octa core CPU's in android phones?

 

I'm looking to buy the Elephone P7000, with a Mediatek 6752 CPU,

Or,

A OnePlus One, with a Snapdragon 801 CPU.

 

 

 

Longer Version:

Now, I know the OPO is a lot better (better single threaded performance, faster and dual channel ram), but I'd be limited by budget constraints and even the 16GB version would be pushing it, whereas a P7000 with a 64GB SD card would still cost less than an OPO. How multi-threaded is Android nowadays? Does Lollipop improve multithreaded support? And does a 64 bit CPU actually make any real world difference (apart from the supposed 30% better optimisations in the android interface itself)?

 

 

I currently have a Moto G with a quad core A7. The P7000 has an octa core A53 - architecturally wise, only a slight improvement, and only a minor boost in clockspeed. Would there be any benefits jumping up to an 8 core CPU, or is it just marketing hype (seeing as the Gen 1 Moto X, with just 2 cores, was one heck of a speedy phone)? My Moto G currently slipped out my pocket and fell down the stairs, so it's on it's last legs and is in need of a replacement, and I'm pretty determined to get one of the two phones above, so any thoughts / actual knowledge would be very much appreciated, thanks :)

What clock speeds are we looking at for the octa core?

 

1.7 GHz for the Octa core, but I found someone online who rooted a phone with the same CPU, and managed to get this up to 2.1GHz (at the cost of disabling 4 cores). Not completely sure if it was legit since I haven't seen that anywhere else, but that may be an option

It's like AMD vs Intel. 8 weaker cores vs 4 stronger cores. However in a phone where aside from benchmarks there's currently TWO apps that can use all 8 cores (Asphalt 8 and Modern Combat 5), get the quad-core, no doubt. In everyday activities such as social networking and UI navigation, the octa-core will actually be worse then the quad core.

Octa-core phones have no advantage, almost nothing uses 8 cores, most things don't even use more than two on phones. They just suck a lot of power and since you have more cores the clock speed is lower resulting in less single thread performance which matters greatly because most things are single threaded so go for a quad-core phone.

Well when using the same number of cores (say, two), the MediaTek will use noticeably less power then the Snapdragon. I've only had one MediaTek phone, which had a MT6582 (quad-core Cortex-A7) and a 2300mAh battery. It was the only phone I've ever had out of my 35+ that could comfortably last me through two days on a charge.

Oh wow, didn't realise there were literally that little amount of apps that can use eight cores. Thought there would at least be a few more benefits to the extra cores. So maybe a big.Little CPU would be good after all (Such as the Snapdragon 618 when it comes out) - 2 high performance, high clocked cores, with 4 low power ones for general texting and stuff?

The Mediatek gets a similar score in AnTuTu as my Nexus 5 does with the Snapdragon 800. The 801 will be stronger, and has better single threaded strength which matters more in the mobile market.

if you have to insist you think for yourself, i'm not going to believe you.

The Elephone has a 3450 mah battery, whereas the OPO has its own magic power saving feature (keeping the display frame stored in RAM, and not re-rendering it unless it's updated), so both phones should be good for battery life. My Moto G with it's 2000 (or so) mah battery could get me through a full day with about 4.5 hours of screen on time. Probably te only time I've been looking for a phone and not really had to worry about the battery life :')

I would go for this one instead then. it had a huuuuuuuuuuuuge battery and is a powerbank thats what they say at the very least

And remember there are just two apps that can use all eight cores but there is something called multitasking too.

big.LITTLE is nice. You get the power of a Snapdragon when you need it and the battery life of a MediaTek when you're not doing anything intensive.

Doesn't mean it's necessarily more powerful. 8 cores will obviously whoop 4 in benchmarks but in real-world usage you will rarely use all 8-cores

My Alcatel MediaTek actually got better SOT then my OPO

The thing is, they claim 2 day battery life with that phone. The p7000 has more than half the battery capacity, as well as a faster CPU, and is cheaper. The P5000 was actually the phone that made me aware of Elephone as a company, but the P7000 would be more beneficial for me. Great suggestion though  B)

Might end up waiting for a device with a snapdragon 618 (if my phone holds out). Although in the mean time, an OPO Mini being released would be much appreciated  :P

What phone do you have now?

A gen 1 Moto G with a very cracked screen (well... cracked where it still is, the top left of the screen is slightly missing, thankfully only the glass before the LCD panel, but that's beside the point)

Sorry, You wrote in the first post= stupid question.

Octo-core is only use in mobile products for battery savings, not for extra performance. Octacores are really just 2 quad core CPUs, one that is at a higher frequency, the other at a lower frequency. This is again not used in tandem for performance.

Depends on the quad core. Standard big.little architectures are built like that, but some allow for all 8 cores to be active at once. And the Mediatek is a true octa-core, with 8 x Cortex A53 cores running at 1.7 GHz. Unsure about Mediatek's marketing though, as the next CPU up has some fancy marketing term, that says it can run all it's cores at max frequency at the same time. Presume this is just some kind of in-build performance governor, though

first time in this subforum..

 

currently faced with the same question about 4 & 8 core phones..not surprised on knowing the little amount of apps fully utilizing 8 cores..

 

sales people keep on bragging "multi-tasking" on 8 cores..i wouldn't necessarily call having many apps open in the background as multi-tasking..but is that right?  :D

lol you know that there is absolutely nothing special about the performance governor right? Literally just has all cores on at highest frequency. There's nothing to optimize that.
