dual core? - Nexus 9 Q&A, Help & Troubleshooting

I thought the tegra k1 had 4 cores running, but my nexus 9 only shows 2. I am sure its no mistake, but was wondering why 2 cores less.

The K1 comes in two variants: the quad core Cortex variant in the Nvidia Shield and the custom ARMv8 64 bit dual core variant (called Denver) in the N9. The quad core version is not 64 bit, but both variants have the same GPU.

[Q]: SetCPU says I have an Arm v7 Processor

Hey guys,
When I fire up SetCPU, under CPU information it says I have an ARMv7 Processor rev 1 (v7l).
Infact, each and every system information tool I've run on my phone keeps telling me the same thing.
These tools also keep telling me I have 1 processor core. Not 2. Got me really worried until the app "SystemPanel" showed me the activity of 2 CPU cores.
PHEW!!! Doesn't this phone have an ARM Cortex-A9 proccessor?
What do you guys see?

Cortex-A9 is a ARMv7 chip. See here
Wow, my ass is officially cool now. Thanks a lot man =D
How donkey kong of me.
if you want to compare it to intel processors, saying that it's ARMv7 is like saying it's a Sandy Bridge processor. Saying it's a Cortex A9 is like saying it's an i5(as opposed to an i3 or an i7).
What is the EXACT FULL Brand name of the processor?
My phone also shows the processor as : ARMv7 Processor rev 1 (v71)
This page http://en.wikipedia.org/wiki/List_of_ARM_microprocessor_cores shows there are several sub classifications of ARMv7......so what exactly is the FULL brand name of this Processor? Is it really dual core? And is it good? Where does it stand when compared to Tegra and Exynos?
It's Samsung Exynos 4210 dual core
Doing a bit of enquiry, I found that both Exynos 4210 and Tegra 2 are SOCs (System-on-a-chip). These chips are jack of all trades, and amalgamate the ARM processor, GPU, anamnesis controllers and alien interfaces into a distinct chip. All SGS II phones with model number GT-i9100 have the Exynos 4210 and the model number GT-i9103 has the Tegra 2. Correct me if I'm wrong.

No ARMv7 is the instruction set, that is different from Sandy bridge which is a cpu architecture. So sandy bridge and cortex A9 are more on the same level but not exactly the same. And i5 is similar to a specific version of Exonys, but I think there only is one version

Really quad core?

Asus told us that the original Transformer was dual core but its actually 1ghz for computing and 1ghz for graphics (which i guess is dual core but not in the way we all thought.).
Just hoping they dont pull something similar with the Prime...

Huh? Not sure where you're pulling your information from, but Tegra 2 consists of a dual-core CPU with each core at 1Ghz and ULP GeFoce GPU running at 333Mhz.
Technically speaking its 5 cores and a gpu.
The Tegra 3, which the Prime has, consists of a 4 1.4GHz CPU cores along with another low-power core. It also has a 12 core GPU.
The TF101, the original transformer, had a Tegra 2. The Tegra 2 had 2 1GHz CPU cores and a 333MHz GPU core.
http :// en.wikipedia.org/wiki/Nvidia_Tegra
I guess it really was dual core, awhile back when I first purchased a Viewsonic G-tablet (I've had every other tegra 2 tablet since) I read a review that said tegra 2 wasnt really dual core because it was using 1ghz for cpu and another 1ghz for gpu. But according to the tegra 2 wiki it really is dual core.
Still dont understand why my Archos 70 runs webpages and go launcher better, it only has a single core 1ghz cpu . Maybe it was honeycomb that made the tegra 2 seem slugish.
Tegra 3 has the 4 cores and that single companion core, so it should have no problems I hope, expecially when ICS hits.

The Tegra 2 is two ARM A9 chips @ 1.00Ghz (and later on, 1.2Ghz) CPU alongside an 8 core GeForce GPU.
The The Tegra 3 is a four ARM A9 chips @ 1.4GHz alongside a 12 core GeForce GPU + a 5th underclocked A9 for power-saving features.

Probably. They made a mistake of not making the home screen hardware accelerated. It's supposed to be fixed in ICS.

How can be xperia t better than galaxy s3?

look at this : http://www.gsmarena.com/sony_xperia_tx_t_and_v_benchmarks_are_here_promising_too-news-4722.php
in the results, the new line of sony xperias, r getting better results on benchmarks than galaxy s3. How can it be? How xperia t with almost the same specification than xperia s gets better results than galaxy s3 with his quadcore processor ?
Quad core is not yet optimized in android
Android is not ready yet for quad core
Dual core is more than enough for android (well ICS)
Because i think jellybean quad core will do better (CMIIW)
Its not just Xperia T all device that use S4 "krait" Dual Core benchmark is always better than exynos

Its the next gen snapdragon S4 plus krait processor..u can find out about those over at their site Qualcomm Snapdragon Processors. Just because S3 and HTC ONE X has quad core doesnt make it act fast coz despite of the cores, the normal apps doesn need to use the quads. May be ull get better gaming fps and smoothness with tegra 3 but when its come to web browsing, stability and working potential the snapdragon chipsets actually does a lot of good work. Waiting for the LG Optimus G. Heard they used S4 PRO Quad Krait

Because cores != performance.
Gesendet von meinem LT26i
Because it's not about number of cores.
Typically the phones with more cores run them at slower clock speeds, canceling out the difference.
It's all about getting a BALANCED spec, which includes I/O rates, flash speed, memory channels, memory bandwidth, cpu cores, cpu power management latency and literally hundreds of other factors.
Both Sony and Samsung are tier 1 manufacturers, which is why they know how to spend money in the right areas when it comes to component costs.

XS Use S3 processor, No Ext Memory, no LTE, 12mp camera
While XT S4 processor, Ext Mem, LTE support, and 14mp camera
If you talking about benchmark
Its pretty far i think thanks to the S4
But the downside is the illumination bar
I really love that bar. if xperia T have that bar i will upgrade without thinking anymore

The new gen S4 PRO comes in two form, Dual and Quad..LG Optimus G went with the Quad 1.5GHz and a shattering 320GPU. Its gona be pretty fast in 3D rendered games for sure and as its Qualcomm then u can very easily bet that there battery consumption will be less than usual Quads
Qualcomm doesn't use reference ARM Design. they just get the license for A9/A15.
They have their own Design like Apple with their SoC.
The Sony Xperia S has the MSM8660 which is a Snapdragon S3 (45nm, Single Channel RAM, Andreno 220 GPU).
The Sony Xperia T has the MSM8260a which is a Snapdragon S4 (28nm, Dual Channel RAM, Andreno 225 GPU).
The difference is also in the architecture.
S3 = Scorpion: This is the own Design of Qualcomm which is compareable with ARM Cortex A9
S4 = Krait: This is also designed by Qualcomm and is compareable with ARM Cortex A15
The performance of Snapdragon SoC's is incredible. Its not just, that Android is not yet optimized for Quad-Core SoC's but also the Design.
There are already benches available showing the APQ8064 which is a Quad-Core with Andreno 320 GPU. There is no compareable SoC at the moment and if I'm not wrong the LG Optimus G will get this SoC (Q1/Q2 2013).

For better GPU performance, i have seen Qualcomm betting more on MSM8960 than any other. I am waiting for S4 PRO MSM8960T chipset review (will surely be used over TABS only) lets see what it got. Didnt read nor know anything about APQ8064 model and i dont think dat we will get to know about that chipset unless LG releases their Optimus G. Xperia T has the AP series from S4 PLUS but S4 PRO is a total new ball game . Am guessing that the next gen S4 chips can easily be overclocked to 2GHz+ as my Xperia-S is already running on 1.78GHZ smoothly and its a Dual Core S3 . LG announced 2GB of ram for the Optimus G so, basically, 2GHz+ of overclocked QUAD PROCESSOR with 2GB ram is a must have for any enthusiast android developer/user. And if they manufacturer make it to a perfection than for sure its a must kept for the next 2/3 years as android for quads, wont be developed before that time but WITHIN that time. That 320GPU is already like a cherry on top so for now, am just keeping my fingers crossed to know how the battery will perform :fingers-crossed:. Then again, thats just my prediction and thoughts . As is said before, Qualcomm already won my faith over their chipsets . More like Dejavu ..More power work yet less power consumed

It's not only quadcore + Android not optimized to be the reason that Xperia T and other new Krait S4 CPU powered phones are better then Samsung's S3.
The S3 is powered by the tegra 3, and tegra 3 isn't the newest CPU anymore. It's just the fact that the S4 processor from Qualcomm is newer and better optimized then tegra 3.

S3 powered by Tegra 3? Where did you read that? It has either the Quad Core Exynos or Dual Core S4 Krait in some models variations.

LOL S3 have Quad Core Exynos .. Tegra 3 is for HTC ONE X and Xperia T came with S4 Plus Dual Core Krait which actually has beaten S3 and HTC both to some serious extent. Hell, HTC ONE S beats one x to some serious level BOTTOM LINE : Qualcomm holds the authentic brain power for androids

Speed or Cores ? - 1.2GHz Quad vs 1.6GHz Dual Core

Guys I need some advice before I buy something
Some devices are equipped with Mediatek MT8125 1.2 GHz Quad Core
while few use Intel Atom Z2560 1.6 GHz
Which chip can perform better ?
Performance wise, battery & tech features..
1.6 GHz Dual core or 1.2 Quad Core
Focus on Speed or Cores ?
Thanks
Mediatek processors sucks in performance, even their octa core is just about on the same if not lower level than Snapdragon processors. But they are power efficient if I'm not mistaken.
Intel however, will blow away everything. Their dual core processors are on the same level and maybe higher than all ARM based processors of there, old ones though.
CMIIW, and some Googleing would help before deciding.
Sent from my blazing fast Nexus 4
Many brands equip smartphones & tablets with Mediatek MT8125 chips..
So its speed that matters more then cores
Yeah, more cores doesn't mean more performance. And RAM too, I think 1 GB wouldn't cut it for 2014. Good luck dude.

Meaditek processors are good bt only main reason is source nt available

The intel one is better. More core doesn't always mean better, moreover when its mediatek which known to be slowest and crappiest among all modern mobile processor.

[Q] Xperia M4 Aqua cores?

Can Xperia M4 Aqua use all 8 64bit cores in same time (example: for demanding games) because they are all cortex A-53 not like Samsung Galaxy Note 4, 4 cores cortex A-53 and 4 cores cortex A-57?

Yes the Snapdragon 615 design alllows the 8 cores to run together but not sure if a lot of android apps areable to use those 8 cores .
