Anyone worried about a quadcore Sprint phone?

I am a little afraid that it will take Sprint a little too long to jump on the quadcore band waggon. As it did the dual core. Am I just being paranoid?

Why would you need a quad core phone? ive had a single core HTC Evo for roughly two years now, no complaints, I don't think battery technology is keeping up to speed with processor advances that's my only real reason.

Well first of all its not that I NEED one, but I want one. Years ago people would have thought a 1gz phone would be crazy. So thanks for the input, but let's stay on topic. I would just like to have a little info on wether or not, Sprint will be getting a Quadcore by end of year next year.

fair enough, was not trying to drag it off-topic but just pointing out the battery life issue as a reason why they may be holding off in the adoption of duel-core and possibly quad core phones.

That's a yea and no. You'll see that the multiple cores gives the phone better battery life due to the fact that the processor can manage processes better giving it better battery. On the flip side, were not perfecting the processors. Were simply flying by through dual cores and quad cores. We were on single cores for about 6 months. Dual cores about 9 and then quad cores were developed. So the developers of these processors need to take more time to perfect the processors, in order to recieve better battery life, less hiccups, more consistency.

The new quad-core tablet, Asus Transformer Prime, has a battery life of 12 hours. This is because it actually has 5 cores. The 5th core is to update small applications with the tablet off so it doesn't have to power up the quad-core and waste battery power. There are probably other factors, but that is one of the main reasons why the battery life id really good on that tablet.

HTC One X has 5 cores?

I'm really confused by HTC advertisement
As we all have known, the HOX comes with a Tegra3 Quad-Core CPU 1,5Ghz
But in some HTC One X Catalog provided by HTC, they say that the HOX has one more core to manage the performance and power to increase the battery life of the device
Can anyone confirm this info? It is really confusing

Yes. The phone has a 1.5 GHz quad core processor. It also has a single companion core which it offloads to for low power. Usually when deep sleeping

Yes, the hox has 5 cores. The last one is a low power core. It is running only when performance is not needed and when the other cores are disable. His goal is saving power.

As people stated here, yes, it has 5 cores. 4 full power cores for harder processes. This is why it's called quad-core. But there's another, "small" one, which is called the Ninja core. It's active when there are no CPU extensive tasks, it eats less battery (smaller consumption) than the "big" ones.
Sounds really nice, although I'm unsure how useful it is. I found different opinions on it. Obviously Nvidia says it's a really cool thing to have, but other people state it's useless, since it's almost always off, others say it's making the things worse, since sometimes it tries to perform tasks, but it's too weak, so the things are slower with it than without it. But as I sad, I don't know, these are just opinions.

FYI the core swithing thingly is hardware control rather than software, less prone to programming mistakes..

I think the ninja core is what accounts for the INSANE standby time HOX can have.

Yeah I think it's quite useful when the HOX is in standby mode or opening small applications. If there are some how the developers can active this core as well as the other 4 in gaming than the game will be a little bit more smoother. Am I right?

nVidia officially call it a '4+1' processor

We've got two clusters in the Tegra 3 SoC.
One is the "G" Cluster, containing 4 cores, and the other one is the "LP" Cluster, containing one core, called "Companion Core" (or also, someone likes calling it "Ninja Core", fugly and inappropriate IMHO).
The cluster switching is not made by hardware, but by software.... if you don't believe that, go watch into the kernel source
...oh and...yeah, nVidia calls it "4-PLUS-1 architecture".
@mr1029x
Absolutely not: you won't have any improvement by activating the LP core for normal operation.
@death__machine
Did you know that the companion core is practically the same of the other cores in the G cluster?

By practically the same, do you mean the companion* core is underclocked or undervolted (software lock)by nvidia?
If thats the case, its similar to how ATI & Nvidia used to reduce the the performance or even pipelines of their gfx cards via software and we could just flash another fw and unlock it.

[Q] Question About Exynos Processor

Hello,
I recently got my Galaxy tab S 8.4 LTE with Exynos. However I have some questions. Sometimes i felt a little bit laggy. Is it normal? Also when I use CPU-Z i only see 4 cores instead of 8. -I am sure it is exynos version- Should not this device run all the cores simultaneously?
And i also would like to ask if there is a way to increase the devices overall performance.
Thanks.

Touchwiz can be a little laggy. You can root your device and freeze or delete a lot of the bloatware. Mines very snappy. Don't experience any lag. I'm still running stock Touchwiz, I just froze all of the bloat which keeps it from starting or running in the background. Also you can flash a custom rom. There's some really good ones available at the moment. Blisspop makes a excellent rom. It would completely get rid of Touchwiz all together.
Exynos is a octacore. However in this tablet it only runs 4 cores at a time. The 1.3 ghz quad core processor runs when your not doing intensive things. So let's say like, browsing the web or watching youtube, checking your mail, etc etc. It uses those to save battery life. Now when more intensive tasks are going on it switches to the 1.9 ghz quad core processor. It's not a true octacore as it only runs 4 cores at a time. However I believe it was the note 3 that had this same processor and there was something called HMP. It allowed the processors to run all 8 cores at once. But us galaxy tab owners do not have that. I don't know if that's something that can be released for this tablet from Samsung. But as of now the device runs on 4 cores at a time and switches back and forth depending on the tasks that are being done.

Interestingly, I haven't had any problems with "lag" with either the stock GUI or because of the background processes.
I must say that despite using the fancy shmancy octo-core battery saving wizardry, my Tab S falls flat on its face with regards to battery savings. In can probably play HD video for 10 hours straight on a full charge, but I don't know if the device could do 5 hours of web browsing if you visit truly bloated modern web sites, like the kinja blogs. I personally suspect that video and other multimedia are run in power saving mode on the slower cores, but web browsing probably calls for the faster cores in many cases. I am thinking it would be cool of there was a way to force everything to run on the slower cores all the time. When I am out in a library or coffee shop without a charging cable, I would have accepted a slower performance in exchange for a long battery life.

Understood. However i am not sure if things go like that. I mean I open CPU-Z and monitor cpu usage. It is not even stable it goes up to 1600 mhz sometimes even though i just monitor it. I wonder if there is a way to monitor my CPU usage with a background APP so i can see if it is overloaded even with simple tasks such as facebook.

If you're rooted you can use an app such as setcpu to modify cpu settings.

If all it does is switch between 2 quad core chips that has to be the dumbest thing I've heard of. What's the point if it can just step the fast one down in frequency and voltage?

Supposedly more efficient with current technology at time of release.
The new 5433 (such as my Note Edge) has true HMP Octa-core processor. So SWEET

Nexus 5X only using 4 cores?

Like many people here and a few reviews have pointed out the nexus 5X seems to get overwhelmed by some day to day task and multitasking. So today as my phone was struggling to load a web page in chrome and stream some Sirius xm over Bluetooth I decided to try and see how heavy the load on the CPU. I fired up cpu z and according to the app it was under a heavy load and the 4 A53 cores were maxed out at 1.44ghz and the 2 A57 cores were stopped! So I rebooted figuring it must have been a bug and nope the A57 cores where still stopped. Anyone else noticing this or is it just my device?

Not seeing that behavior, although it's possible cpu-z needs an update or is buggy; after launching the camera to generate some load, it showed all 6 cores as being [email protected] until I restarted it.

the snapdragon 808 uses the bigLittle architecture.
That means there are 4 low powered cpus, and 2 high powered cpus.
Most of the time, only the 4 low powered cpus are in use.
When the phone needs more performance/power, the 2 other high powered cpus kick in.
So what you are seeing is normal. Most of the time, the phone is only using the 4 little cpus.

I don't think cpu-z should show all six cores as A53s though, only the little 4. That's the part I think might be a bug.

trickster mod works, I see the 2 big cpus kick in all the time, but it requires root.

So after trying a bunch of different things out looks like running a benchmark will someone's get all the course up and running but not all the time the first screen shot is with 4 cores and the 2nd is with all 6 both seem pretty low to me

Octa core? Quad core? Help me please😭

Sorry for my poor english. But something i really want to ask. Help me please.
I've got some problem on my z5 premium dual(6883). I'm not sure if it is problem of my phone or all e6883. Please can anyone help me or tell me?
z5 premium/z5 premium dual are using s810 with 4-a53 cores and 4-a57 cores. But my phone is always using the 4-a53 cores but seldom use a57 cores. Even use a57 cores, just use only maximum at 2. It is so weird. And even the 4-a53 cores are all fully used (usage: 100%), it won't switch to use or active a-57 cores.
So, my question is, can anyone tell me this is my e6883's problem or all e6883's problem?

the second processors usually get ignited ONLY if resources are LOW on the first chipset. running two simultaneously will drain battery!
don't worry! enjoy the device

Thx for answering me.
But i have still got a question. Just now i'm trying to open snapchat to reply my friends and i figured out my a-53 cores are fully loading about half minutes but the a-57 cores are still sleeping Is it just my e6883's problem? or something else?
I've captured my screen. Please have a look.
(left hand corner is the cpu temperature)
