PowerVR G6200 clock rate - Redmi Note 2 Q&A, Help & Troubleshooting

I've read that the 16Gb Redmi Note 2 has the GPU running at only 550Mhz while the Redmi Note 2 Prime has its GPU running at 700Mhz. Is this correct?
If it is, it's a much more significant difference than the 0.2Ghz in CPU clock.

I posted the exact differences somewhere (here).. you can look for it.

Lenovo 'Transformer' IdeaTab S2

So will you guys be swapping your Asus Transformer Prime for a similar product? Im sure most people are purchasing this due to the extra keyboard dock or tegra 3.
EDIT: Personally I'll be sticking with Asus Prime for now, its a good device.
Specification:
10.1" Screen IPS Display
Qualcomm Snapdragon 8960 (28mn TSMC) Dual-Core 1.7Ghz / Adreno 225 GPU 400 Mhz (Overclocked Adreno 220 + Better driver)
20 Hour battery Life
Keyboard Dock like Asus Transformer
16/32/64gb
The GPU is just on par with Mali 400MP which is a shame (GLBenchmark) but that is early benchmark.
Overclocking should be alot better for the CPU, since its a 28mn, I guess reaching over 2.0Ghz is fine!
Information:
Lenovo Idea Tab S 2
We need to start the review by mentioning that there may be certain ambiguities in the specification listed here for Lenovo Idea Tab S 2 since it’s actually not the official release. But as the prior experiences suggest, these information are normally bound to be true. So let us proceed with them. The Lenovo Idea Tab S 2 is to have 10.1 inches IPS display with a resolution of 1280 x 800 pixels which would be a state of the art screen panel and resolution. It will have 1.5GHz Qualcomm Snapdragon 8960 dual core processor with 1GB of RAM. This beast of hardware is controlled by Android OS v4.0 IceCreamSandwich and Lenovo has included a completely modified UI called Mondrain UI for their Idea Tab.
It comes in three storage configurations, 16 / 32 / 64 GBs with the ability to expand the storage using a microSD card. It features 5MP rear camera with auto focus and geo tagging with Assisted GPS and while the camera isn’t that good, it has decent performance verifiers. Idea Tab S 2 will come in 3G connectivity, not 4G connectivity which certainly is a surprise and it also has Wi-Fi 801.11 b/g/n for continuous connectivity and they claim that this tablet can control a smart TV so we assume they have some variation of DLNA included in Idea Tab S 2 as well. Following the footsteps of Asus, Lenovo Idea Tab S 2 also comes with a keyboard dock that has some additional battery life as well as additional ports and an optical track pad. It’s such a good concept to be replicated from Asus and we reckon it would be a deal changer for Lenovo Idea Tab S 2.
Lenovo has also made their new Tablet rather thin scoring a mere 8.69mm of thickness and 580g of weight which is surprisingly light. The inbuilt battery can score up to 9 hours as per Lenovo and if you hook it up with the keyboard dock, 20 hours of total battery life is guaranteed by Lenovo which is a very good move.

I certainly won't be going through the trouble of changing to this. This doesn't really look to add anything of value for me (don't need gps and my wifi works fine), and if pricing from lenovo in the past stays true this will likely be more expensive then the equivalent primes.

That's surprising because of the GFLOPS specs for the GPUs:
Tegra 3 Kal-El: 7.2 GFLOPS
Qualcomm 8960 Adreno 225: 19.2 GFLOPS
PowerVR SGX543MP2: 19.2 GFLOPS
And per Anandtech "Qualcomm claims that MSM8960 will be able to outperform Apple's A5 in GLBenchmark 2.x at qHD resolutions." Of course, Qualcomm would say that but even if it is on par with the iPad2 (543MP2) it will still significantly outperform the Tegra3.

Yes but driver is the most important. Since Tegra 3 Ka el is clocked higher than 300Mhz, the 7.2 GFLOPs doesn't count.
I'd doubt it'll significantly outperform the Tegra 3 GPU. Just like the Adreno 220 was meant to be better but isn't much different.
Even Qualcomm admited that it'll only have 50% more performance than its current Adreno 220.
FML, GLBenchmark took down Asus TF202 with the GPU. It just performed lower than the Mali GPU, wish I saved the website.
With Adreno 225 Qualcomm improves performance along two vectors, the first being clock speed. While Adreno 220 (used in the MSM8660) ran at 266MHz, Adreno 225 runs at 400MHz thanks to 28nm. Secondly, Qualcomm tells us Adreno 225 is accompanied by "significant driver improvements". Keeping in mind the sheer amount of compute potential of the Adreno 22x family, it only makes sense that driver improvements could unlock a lot of performance. Qualcomm expects the 225 to be 50% faster than the outgoing 220

Yes, I saw that comment posted in another tread and I tried to google it but could not find it. Hopefully, Anandtech will put something out soon once demos for these newer tablets are available.
I've personally had a lot of headaches in the past with Lenovo laptops so I doubt I'll be making another Lenovo purchase. (Google "Y530 Lenovo Hinges" if you're interested in the issue- it was a common problem due to faulty design.)
The powerVR and Adreno have much more efficient rendering methods than the Tegra chips, so this tablet is no pushover at all.
I wouldn't be surprised if real world performance is better than the tegra 3 outside of tegra 3 specific apps.
hey
The Adreno 225 + SGX 543 MP2 both get 19.2 gflops @300mhz. we dont know the clock speed of the A5 but we can speculate that its probably around the 250-300mhz range.
That makes the Adreno(@400) more powerfull in flops than even the A5/tegra 3, however flops dont tell the whole story, as the A5 has twice the number of TMU's so has a higher fill rate clock for clock and better texturing capability.
The A5 will likely have more ROPs as well, but i dont know that.
The A5 will also have slightly higher bandwidth i think.
Looking at what Anand has said, the adreno 220, only had single channel memory=low bandwidth, it also probably poor effeciency in getting data to the shaders, i think Power vr are more effecient than adreno 2xx series.
The drivers on Adreno were not very good either, indeed some developers on this forum have managed to DOUBLE the adreno [email protected] using the newist Adreno drivers from qualcomm, i think shaky153 was leading the charge with.
I would be very suprised if the Adreno 225 equaled the A5, but it might equal or slightly beat the tegra 3..especially at higher resolutions due to tegras lack of bandwidth.
I don't understand why Nvidia doesn't announce the GPU clock speed!! they detailed it with T2! which means there is something to hide
AP25 was 400Mhz, so T3 shouldn't be under 400mhz
this discussion would be a lot easier if we know the actual clock speed
Prime/Nvidia rules!
Plus Lenovo had No developement support at all. And they are one of the slowest to release firmware updates. Everything is basically dead in Lenovo land.
It seems OK. But nothing enticing to make me think twice about trading my Prime. PRIME is just to cool all around.

How much faster will Tegra 4 be vs Tegra 3?

Trying to see if i should wait until q1 of 2013 to pick up a tegra 4 tablet. I have a transformer prime atm but i will return it soon. I read something about a15 gpu being much more powerful than the a9 that tegra 3 uses?
A15 are CPU cores and if used that would give more processing power for less battery use. (same as with today's Qualcomm S4 Krait)
As for GPU part, roumors suggest it will come with something between 32-64 cores, as opposed to 12 in Tegra 3.

Safe CPU overclock

I've using 1.7GHz for a few days on pegasusq governor but was wondering how much CPU life is affected each clock interval.
My guess is the S3 is underclocked at 1.4 because the Note 2 uses the same Exynos 4412 SoC @ 1.6.
By logic 1.7 let alone 1.8GHz isn't overkill, provided a stable voltage: would I be right thinking this?

I heard the Note 2 uses Version 2 of the Exynos 4412 SoC, the S3 uses version 1. So there is a difference between them
Why overclock in the first place? Mine is silky smooth on stock 1.4 ghz

Apart from ****ty battery life, what does overclocking actually get you?

I think the true answer for the majority is.... bragging rights
It helps CM10.1 run smoother when needed in my experience. Battery life hasn't taken a noticeable hit. 4-5 screen on.

[Q] Tegra 4 Question.

I have seen that there is two versions of Tegra 4. One with a clock speed of 1.9 Ghz and one with 1.8 Ghz. So i was wondering if the these two have different GPU clock speed as well, like in the differnet versions of tegra 3?
http://gfxbench.com/device.jsp?benchmark=gfx27&D=NVidia+Shield
http://gfxbench.com/device.jsp?benchmark=gfx27&D=HP+Slatebook+10+X2
These two "Tablets" have as it appears the exact same processor exept the CPU clock speed, but the GPU score are different as well. So i guess that the GPU speed are different too. What do you guys think?

graphic performance is worse than adreno 512 gpu

I don't know about how much the benchmark reflect
real life performance of device but this is interesting.
few day ago i was talking to my friend who has same phone redmi note 7 pro and he said that his older phone which was Xiaomi A2 was better performing in pubg.
i didn't agree because it has 512 gpu and redmi note 7 pro has 612 gpu so i told him that this gpu is updated and is better than 512, but then i started to compare both gpu on this website
https://www.notebookcheck.net/Adreno-612-vs-Adreno-512_9876_8778.247598.0.html
and i was surprised by the results
and the i opened 3dmark website to check and i found that in gpu performance redmi note 7s, redmi note 7, and Mi A2 perform better that redmi note 7 pro how is this possible or how this processor or gpu upgrade work in phones.
this is the link of 3dmark result of phones
https://benchmarks.ul.com/compare/best-smartphones?displaySize=3.0,13.4&search=redmi note 7
I think I am the right one to answer this. I own both devices, and trust me... Rn7pro is miles ahead in terms of cpu and GPU performance from Mi a2.
Your friend sounds like a tool. I don't know about the benchmarks, but pubg by default selected high settings in graphics on rn7pro. And also by default, you can go upto ultra fps settings without using any graphics tool for PUBG.
Whereas in mi a2, pubg selects medium fps and by default the maximum fps supported is high.
I play on ultra settings and the rn7pro maintains a steady 40-45 fps(goes upto 52 depending on the scene being rendered).
Also keep in mind that qualcomm's series 6xx processors are based on custom kryo architecture.
Snapdragon 675 even beats 710 and 712 in benchmarks. The reason is the fact that Snapdragon 675 is based on kryo 460 model. Google all this and you will come to know what these terms mean. Snapdragon 660 which powers mi a2 is miles behind both in GPU and cpu performance.
