URGENT! is my Note 3 normal? - General Topics

I've some questions...
1) The Indian Note 3 model number SM N900 and not SM N9000. Correct?
2) The EXYNOS 5420 chip that powers the Note 3 is supposed to be an Octa core processor. However, in the phone details (using Antutu benchmark tool / CPUZ) all the 8 cores aren't visible. While it says that there are 4+4 cores, only the Cortex A15 @ 1.9 GHz with "core 0, core 1, core 2 and core 3" is visible. The other one - Cortex A7 @ 1.3 GHz with the remaining 4 cores isn't visible. What is the reason for this? Is my phone a 'wrong piece'? Should I ask for replacement? Or is this normal? If this is normal, why so? Where did the other processor and the remaining 4 cores go?

I do not have a Note 3 but the Exynos Octa-core isn't actually a octa-core. There are 4 phisical processors and 4 virtual processor, so that's somehow a fake octa-core and possibly that's why antutu shows you only 4 processors.

1) N900 and N9000 are the exact same thing. Samsung devices have a 5 or an 0 at the end to indicate LTE(5) or 3G(0) devices. With the N9000, they simply dropped the last 0.
2) Benchmark tools can only detect one active CPU at a time (Physical or Virtual), so they automatically detect the first physical one.

[Q] Asus TF700T running quad core or dual core?

Hello.. Can you guys tell me is asus infinity TF700T running a quad core or dual core? Cause under the spec of Asus website it said using quad core. But on my Infinity its said using a dual core, using a ES Task Manager to check. Just bought the Infinity couple week ago:
Android version: 4.0.3 Model number: Asus pad TF700T
Build number: IMEI
CPU frequency: 1700 Mhz (Dual core) CPU model: ARMv7 Processor rev 9 (v7I)
Kernel version: 2.6.39.4 Screen Res: 1920:1128

SMP PREEMPT
THX....
It's quad core. Dunno why that app says otherwise.

If you are on the snapdragon processor, with phone service, not the WiFi only version, you are dual core. But I didn't think they were out yet.

Is there another way for me to double check the cpu processor? Thx

I saw an app on Play once, (can't remember name of it) was a task manager, but it was for quad core. Wasn't a free app, though.
Actually the Tegra 3 runs 5 cores with the last one being for low battery consumption processes. Nobody really knows if that is actually true or not but that is what Nvidia claims. Just say it's quad core. Android really doesn't take great advantage of more than two cores so that is likely why you are seeing only 2 cores in the app that you are using.

dual-core vs. quad-core

Hello all!
Long time reader, first time poster! I had a quick question... regarding the new 1.5 dual-core processors in the new phones (SIII, RAZR HD, etc., or even the HTC Rezound) vs. the quad-core processors soon to release on the newer phones in the coming months. How much faster is the quad-core vs. the dual-core? Please don't respond with "twice as fast," I get that I was wondering if there would really be any noticeable difference in the speed capabilities of the phone, even when worked to it's limit.
For instance, 1 degree vs. 2 degrees temperature - it's "twice as hot," but you're not going to notice it at all. But 40 degress vs. 80 degrees - "it's twice as hot" has a whole new meaning!
I am wanting to get a new RAZR MAXX HD, but was debating holding off for the LG Nexus or another quad-core phone that's on the horizon... Thanks in advance for all your help!
In Europe SIII has a quadcore too

Personally I don't think it's noticeable at all. Maybe when browsing web, rendering goes faster in multi-core optimised browsers. And of course some games would run better. But I can't imagine any other use, unless you want to run SuperPI in the terminal there. It'll probably run nearly twice faster.
Edit: From the other point. There will be more and more optimisations in Android for multi-core SoCs, so quad-core will for sure "last longer".
Rebellos, thanks for the help! Not to open a whole can of worms, but what do you mean "run SuperPI"? Is this an app that I should be familiarizing myself with? (Fairly new to the ROMs, rooting, bootloaders side of things)
When I got my captivate, I had the option of waiting a month to get the atrix which had a dual core processor. I choose to go for the sure-fire "I Know it'll have dev support" single core processor and don't regret it.
This time however, there are like 3 quad core devices coming out. One x+ has a tegra 3, the Note 2 has an exynos. The Optimus G has an S4.
While dev support is still important.. the S4 is an incredibly compelling factor for me personally.

SuperPi is nothing more than a benchmark you really don't need to concern yourself with.
Remember when you are talking about cores, it is not simply the number of cores that you need to take into consideration but also the architecture which those new cores are built on. The new A15 Krait chips are dual core, but will blow the door off a quad core CPU with an older architecture. MHZ and Cores are relative. If they put out a modern super phone with a dual core processor you can bet those are two beefy and very fast cores.
There is the valid point that Android is going to continue to specialize in multithread execution but 1 core does not necessarily translate into 1 thread. A hyper-threaded cpu core actually shows up as 2 physical cores to the computer it serves, so if you are running a dual core that is hyper-threaded the PC thinks there is a quad core on board. It also depends on what type of application you are running as to whether a very solid 1 thread computational approach would be superior to a multi-threaded approach.
In short there is not set answer. There are hypothetical road maps defining architecture but these days innovation is so common said road maps could made an abrupt 180 if circumstances change. When if is time to buy a phone, or any computational device, consider what it's primary task is. That could help you decide whehter a multi or single threaded approach could be more effective. Ultimately as mentioned earlier everything is going the way of the multi-core, multi-thread, meaning instead of having 1 processor/thread complete 1 job, muliple processor/threads complete several mini jobs to arrive at the same point. Usually a multi threaded approach is more effective if designed correctly. Then look at what is available, where is your bang for the buck. Ultimately the number of cores and frequency run at has little to do with processing prowess. It's about design, innovation and engineering. Sorry if this didn't help much. It was more designed to give you something to thing about as apposed to pat, here you are, here's your answer as I rarely believe there is 1 approach or 1 answer to a solution. That's what computing is and computers = phones = innovation.
For gaming it makes a difference. For everything else, not really. Comparing the HTC One X vs the One XL (Tegra 3 Quad vs Snapdragon S4 Dual, respectively), the One XL benchmarks as faster than the One X CPU-wise (calculations), but the One X is more powerful graphically because the GeForce GPU inside the Tegra 3 chipset is more powerful than the Adreno 225 inside the Snapdragon S4. I have the Galaxy S3 i9300 while my girlfriend has the AT&T Snapdragon S4 Dual (LTE + 2GB RAM) version. Mine is clearly faster when it comes to heavy gaming, noticeably. Hers jerks on certain games like Beach Buggy Blitz, even on middle-level resolution, while mine runs completely smoothly on the highest resolution.
The only real comparison would be Snapdragon S4 Dual vs Snapdragon S4 Quad, or Exynos Dual vs Exynos Quad. The Galaxy S2 was as smooth as the S3, from personal experience (Sprint, Exynos version vs GS3 International Exynos version). Gaming was also super fast. But the Exynos quad is definitely more powerful.
TL;DR: It depends heavily on the chipsets being compared.
I have a T-Mobile Galaxy S2 running AOKP JB. In my opinion AOKP JB is A LOT faster than CM10. My phone is really fast now. Dual-core is still good.

True, but that's a completely different architecture. Exynos 4412 (the one in the i9300) is based on Cortex A9, whereas the Exynos 5520 is Cortex A15. It's like saying quad-core Pentium 3 vs dual-core Pentium 4. The Pentium 4 is a more advanced architecture, so it would win. It's like comparing apples to oranges.
Yes the 4412 is just double Dualcore

Exynos 4412 is the quad core version in the Galaxy S3 i9300. The Exynos Dual core inside of the Galaxy S II is the 4212.
Thanks for all the advice and tips everyone! And thanks to fusuikan for the very lengthy explanation of SuperPI and insight into processing chips!

But Samsung has just doubled the cores and not founded a new processor

For heavy games it makes difference.
In my opinion, a A15 based dual core may be a better as an overall proposition compared to a quad core A9. The A15 should have approximately 20%-40%+ better single threaded performance. Most of the time you are working in a single threaded mode.
In fact you only need quad core when using a very high multi-threaded load. Not very common on a phone.
If however the choice is between a dual core A15 vs a quad core A15, the choice becomes very straightforward. Get the quad-core in that case.
Dual Core A15 vs Quad Core A9 (of the same type of chipset, like Exynos 4412 Quad in the S3 vs Exynos 5520 in the Nexus 10/Samsung Chromebook), Dual wins. It's more efficient and just overall more powerful. The first A15 chipset are the Snapdragon S4 Pro (Quad only) and the Exynos 5250. It's speculated though that the Galaxy S4 will have an Exynos 5 Quad.

Actually its Exynos 5250 not 5520 and s4 pro is not based on A15 architecture its quite similar but A15(dual core) gives better performance than s4 pro(quad core) in single threaded operations ,but in multi threaded operations s4 pro is better,but with same number of cores on both ,A15(quad core) would be better than s4 pro(quad core) in both multi threaded and single threaded operations.

The note 3 with the Snapdragon processor is better than the one with Exynos.
The Snapdragon processor Runs with 2.3 GHZ quad core and the Exynos runs with 1.9 GHZ quad core also the Snapdragon one supports 4G and the Exynos one not.
But there aren't a big difference..
The Snapdragon one can record Vids in 4k Resolution (3840x2160) and the Exynos one can only record Full HD (1920x1080).
The last difference is that the Exynos one use more RAM while in idle-modus, The exynos one uses 1,3/1,4 GB of the 3 GB and the Snapdragon one uses 1,0/1,1 GB of the 3 GB
Snapdragon no doubt

Single or Quad core GPU?

Hello, i bought a china phone with quad core mtk6582 cpu.
In Antutu benchmark show that cpu is - 4+4 cores - what it this? 4 cores or ?
For the GPU - Antutu say - Mali 400 MP
But i see that this MTK6582 , have mali 400 mp2 gpu - so which is correct antutu or ?
I Try with another benchmark quadrant standart - and there also show mali 400 mp as a single core.
Do you know how much cores is this gpu?
Thanks
Maybe antutu was wrong,try google it bro,maybe it can help,check it on mtk website or your phone's brand website

go with the 2 gigs, mali and mediatek are terrible GPU's/CPU's snapdragon and adreno beats the crap out of them. octa core means nothing, phones dont need 8 cores xD quad is just fine.
