mali 400 gpu the weakest out?

how weak is this gpu, is it overclocked ?

its pretty outdated, regardless what anyone else says to you
it has half the die size of a 544mp4, which is kind of sad ... the mali400 in note 2 is overclocked versus the one in the gs2, and is suppose to be an improved variant from the galaxy s3
it is faster than tegra 3, ill tell you that for sure

something is strange, i wonder if the note 2 gpu is a variant in the way the adreno series like adreno 225 but samsung just doesnt change the numbering maybe, what do you think, if its a variant, there must be changes, no way it can pull figures like it does while being a s2 gpu lol

[Q] Which CPU does my Tab S LTE have?

How can I find out which CPU my Tab S 8.4 LTE has ? I bought my tablet from on online Italian dealer.

They all have Exynos (except some rare US and Chinese models).

Install and run the cpu-z app. It will show you the cpu and lots of other information!

Well, I am more confused now.
I called Samsung and they accessed some internal technical data that I couldn't find online. According to the customer service rep, my LTE device (SM-T705) has a 2.3ghz snapdragon 800ghz quad core for the LTE functions and a 1.9 ghz exynos quad core. The non-LTE (SM-T700) has a 1.9ghz quad core exynos and a 1.3ghz quad core exynos (i.e., exynos 5 octa). So, according to them, my device isn't octacore, but dual (heterogenous) quad core. That's exactly what the rep told me. Hmmmmmm
Here is what cpu-z reports:
1) 4x ARM Cortex [email protected] 1.90ghz
2) 4x ARM Cortex [email protected] 1.90ghz
3) GPU Mali T628
It doesn't explicitly say if the brand of each 4-core CPU. I was unaware and A-7 could run at 1.9, even overclocked.
Here is what the CPU/RAM/DEVICE Identifer app reports:
1) Exynos 5 5420 Octa x4+4 1.9ghz.
According to this thread (http://forum.xda-developers.com/showthread.php?t=2438339), the 5420 is an A-15.
2) 3) GPU Mali T628
My observation here that maybe the device is using an LTE chip separate (not integrated) alongside an exynos octacore. It's possible according to an Australian forum: "Samsung is buying LTE modems from Intel and using them with their own Exynos 5 Octa (5420) SoC, as using in-house silicon reduces manufacturing costs."
To show how confusing this is, here is what I found on Wikipedia, describing sort of vaguely the Tab S 10.1 cpu (no similar description for the 8.4):
"The WiFi model of the tablet is powered by the Samsung Exynos 5 Octa 5420 CPUs. The LTE model comes either with a Quad-core 2.3 GHz Krait 400 on top of a Qualcomm Snapdragon 800 chipset (version for some US carriers) or with the Exynos octa-core CPU (version for some European countries)."
That seems to say the LTE version has snapdragon quad core plus another snapdragon quad core OR an exynos octacore. That would mean they'd have to have turned off the A-7 core. Either way, I thought a snapdragon would not work with the Mali GPU.
In the end, still confused, but I'm leaning toward believing it's all exynos plus that intel LTE modem. As to which cortex cores, I dunno.

They are all exynos apart from ramdom US ones as mentioned before. There is huge confusion online. Its an exynos with two quad cores but no hetrogenous processing.

Thanks for the replies. An all exynos system makes sense. Clearly, one quad core is 1.9ghz. I wonder what the other quad core runs at. The CPU-z type apps are giving conflicting results. And, clearly Samsung customer service has no idea. They think I have an exynos 1.9ghz quad plus a snapdragon 2.3ghz quad.

Wrong thread

It's four ARM Cortex A15 cores at 1.9Ghz and four Arm Cortex A7 cores at 1.3Ghz.
They call it the big.LITTLE concept where the A7 cores are for low power/light tasks and the A15 cores for performance.

Totally 100% correct.

Again, thanks for the help. It will be interesting to see what the Tab S2 will have in it beside a 4:3 form factor and a much lower capacity battery.

Likely the new 7440 exynos. (May have got that model number wrong!)

I guess when it comes out, I'll put my T705 on eBay. Gotta stay current ☺

Christ it comes to something when even Samsung doesn't know what's in there own devices!
This forum doesn't help either by having the wrong specs at the top of the forum page.
The majority of tab s's have the exynos cpus not snapdragon and this should be reflected in the spec details in this forum.
I can see how newcomers get easily confused.

Galaxy Tab s LTE verion T805 Running Snap dragon or Exynos

Dear Friends, i got an question to ask somebody here .
Well if I'm fool but i really doubt and no clear about this tablet as in the description they said For T800 Wifi device is running Exynos 5 Octa processor, octa-core 1.9GHz processor and quad-core 1.3GHz processor and for LTE devices are powered by a Qualcomm Snapdragon 800 2.3GHz quad-core processor.
And I have my galaxy tab S 10.5 LTE version T805 but in fact the processor in my device it Exynos Octa 5420 1.9ghz and quad-core 1.3ghz depend on CPU Z test result it's look actually same Wifi version. so Which LTE version that running snap dragon 2.3ghz ?
Please mind my English but hope someone here help me to explain about this .
P.S I also checked many review about this device but still i didn't get it .

Only a couple of the carrier related versions use the snapdragon cpu, the rest are all Exynos.

I though for all LTE version is running snapdragon CPU 2.3ghz that's why i bought this device .. anyway i like using device that running snapdragon processor because it's cause less battery and good performance for gaming ..

Nexus 7 Snapdragon 600?

According to CPUz my Nexus 7 has a Snapdragon 600 should it not be an S4 pro?

The S4 pro has 4x Krait 200 cores and support LPDDR2 RAM modules. The SoC in nexus 7 has 4x Krait 300 cores and support DDR3L-1600MHz SDRAM modules.
So I think, that it's just basically underclocked snapdragon 600, but they call it like a S4 Pro, because of the underclocking (snapdragon 600 is clocked at 1.7GHz)

Exynos or Snapdragon CPU?

which version is better CPU Exynos 9825 or Snapdragon 855+? for a games? for a job? for a see videos?
Thank´s a lot

Note 10 has the 855 not the +. Just a fyi.

Both are very similar 855 little ahead in benchmark which u won't notice in real life , i just know Exynos runs cooler i heard .
