SGX 540: SGS vs LG Optimus 3d

I just read an article here: http://www.anandtech.com/show/4179/ti-omap4-and-lg-optimus-3d-tested
The LG Optimus 3d uses the same SGX 540 graphics that our SGS uses. BUT it is clocked at 300mhz vs our 200mhz AND it uses an updated driver. With these improvements, early benchmarks show it beats the tegra 2 and the quad-gpu in the SGS II. Of course these benchmarks don't tell the whole story, but I still find it interesting. I hope Samsung can make sure android can take advantage of the gpu in the SGS II.
Most PowerVR SGX 540 designs run the GPU core at up to 200MHz. OMAP 4's implementation is another 50% faster. LG's software build also uses a newer version of Imagination Technologies' driver (1.6 instead of 1.5) which fixes some rendering issues (specifically in the Egypt test) and improves performance considerably (likely between 10 - 30% in GLBenchmark2). You can see that the image quality issues are fixed in the video showing the Egypt demo running on the LG Optimus 3D below:

Taking the performance improvement due to the driver out of the equation, we're still looking at a nearly 20% increase in performance over the SGX 540 in Hummingbird. The 4430 holds a similar advantage over NVIDIA's Tegra 2.

Hey, I want this driver! Maybe, devs could be able to port it to SGS somehow.
By the way, GPU in Desire HD and Desire Z (adreno 205) beats SGS one in benchmarks and goes head-to-head with Tegra.

if it causes the same battery drain, i want that driver too...

Id love to see how the Sony NGP with ARM Cortex-A9 quad-core processor & SGX543MP4+ GPU stacks up....just for fun of course.

The SGX540 is indeed a very good GPU. Still not outdated, even at 200 MHz.

You can change it the kernel also to 300MHz if you have te skils. Our SGS has stil many potentional

I hope skilled devs like Supercurio and Hardcore are reading this thread and get some inspiration

F**king apple
I hope everyone is realizing how dumb it was to let apple buy imaginetech.
And how come nvidia (a company i know for gpus) seems to be behind in gpu tech?

Unlikely when you mess with the gpu clock there's an increase in instability, as well as putting other devices out of sync. I believe omap4 is using a different nm process to fabricate it probably smaller than the galaxys so they can put the clock higher.
The driver upgrade is the only possibility.

I think Hummingbird (A8) and Omap4 (A9) are based on same 45 nm architecture.

Guys, look at that:
http://glbenchmark.com/subtest_results_of_device.jsp?D=Google+Nexus+S&id=405
There are 12 tests of Nexus S in GLBenchmark, and 11 of them are below 2400 points (more or less like our SGS), but the most recent one (uploaded at 2011.02.11) scored 3025 points, more than Tegra 2. This result's is made by someone from GLBenchmark, and shows at "GLBenchmark team tested" page of the results. How is that possible?

Just commenting to keep this going. I don't want to put my hopes up too much, but you never know

I'm beginning to believe that it was a bad move from Samsung to switch from PowerVR to the Mali-400. I have the money ready to spend on a new device and I hope it's the SGS2 but I will wait first for the final product and drivers and see some benchmarks before I buy. If the SGX540 keeps the lead maybe I'll stick with my SGS.

samsung got tegra 2 also for I9103 phone
but SGX543 was good a option

Samsung pr overhyped their processor capabilities. But I guess there not confident in there own soc. If they decided to make a tegra 2 version.

i'm pretty sure they are only making a tegra 2 version because they wont be able to manufacture enough orion cores to meet the demand.

i think that the galaxy tab gpu is clocked at higher speed than galaxy s as it gives same score at neocore on (1024x600) resolution , am i wrong

Give an App for gpu oc please Dev's
And of course DRIVER update please

Interesting. I did see GPU overclock to 247mhz in some kernels, but any driver upgrade or OC is awesome

iPhone 5 catches up to flagship droids in first Geekbench scores

There was plenty of speculation what kind of CPU powered the new iPhone 5 and in the end it turned out to be a custom Apple design. So, how well did the Cupertino-based company did? According to an unverified Geekbench results, A6more than meets the 2x performance increase Apple promised.
The results are nothing short of amazing - the Apple A6 chipset has two custom cores rated at 1GHz with 1GB of RAM and it easily stands up to quad-core Cortex-A9 and dual-core Krait designs running at 1.5GHz.
The iPhone 5 has more than double the CPU performance of the 4S, beating it in every category that Geekbench tests. The RAM has gotten faster too. Even the A5X in the new iPad can't compete (understandable as A5X only improves GPU performance over the A5).
As for high-end Androids, Exynos 4 Quad and Tegra 3 based phones like the Samsung Galaxy S III and the HTC One X manage to outperform the iPhone 5 if they are running Android Jelly Bean. Under Ice Cream Sandwich, the performance of the One X drops down to the levels of the iPhone.
The HTC One S and its two Krait cores manage to match the iPhone 5 under Ice Cream Sandwich, so it should come out slightly ahead.
Just for fun, here's a dual-core Pentium 4 541 (Prescott architecture) downclocked to 2.4GHz matching the performance of the iPhone 5. This CPU came out in Q3 of 2004.
If these benchmark results do turn out to be from the iPhone 5 (results can be faked, so take it with a grain of salt) then Apple must have worked some serious magic. The Apple A6 chipset makes even Krait cores look slow (again, it's 1GHz vs. 1.5GHz).

See... How many S III scored lower than 1601...
All with JB leaks beats iPhone 5 score...
i think the benchmarking tool is a bit of weird. The One S also scored 1.5k... Not X but S.... S4 processor. Maybe it does not really use all the 4 cores?

the benchmark tool is useless... its more OS based then anything... change your launcher that u use and u'll get a different score every time...

I think you need to learn how to read geek bench the majority of iPhone 5 score is in fast memory the processor is still pretty slow by itself. Also mod please close this thread all iPhone threads crash and burn.

why people open everyday same **** again again(@OP : Is apple marketing team has ordered open new thread everyday?). the iphone 5 have nothing new. just to say thinnest and tallest (but these kind of models already available years ago. ). If you want compare iphone 5 to galaxy line you have to compare it with galaxy s, sII or galaxy sIII mini. It's not worth it to compare to with sIII.
(By the way iphone5 cpu and memory provided by Samsung.)

I think they used the US S3 which is dual cored, instead of the international S3. That's why the scores are lower.

1.Why post this on here?
2.A newer phone that is somehow faster....really? is that how technology works, well if it is then I guess the SGS4 to be even faster, and the SGS5, and I will go as far to say that the SGS24 will be greater still.

i think a lot of you who post Samsung s3 vs. whatever is insecure and are those who always want to have the best or be the best. People are competitive by nature but being obsessive, wasting your time and energy on products that serve the same purpose is a bit overkill. My advise is to find a cure for the disease you have. Just enjoy your phone.

is my sm-n900 fake according to the benchmark ?

hi , i have a Vietnamese made galaxy note 3 ( or that what it is written on the back side of the cellphone ) , it was really good , and i didn't suspect that it could be fake .... today i decided to run quadrant benchmark , it scored 18060 ... which was a little bit lower than the normal score for the note 3 ( it could reach 22000 )
when i checked the processor in the system specifications , it showed this :

is it the real cpu information for the sm-n900 ? shouldn't it have 8 cores ( octa ) instead of 4 ? and how about the maximum frequency ( 1900 mhz ) ?
thanks in advance

i ran the Phone INFO ★Samsung★ application and it said that it is original , but i am still not sure about the processor cores ,doesn't exynos mobile have 8 cores ?

It is a real one. SM-900 has 2 sets of 4 core processors. One set is low power A-7 and other is high power A-15 set. At a time only one set is active. In case of benchmarks, only the high power cluster works. Try downloading an app called CPU-z in the play store.

thanks for your reply , but may i ask you what advantage would i get from the octa core if only one quad is able to run at a time ? what difference would it make when compared to other quad core cellphones ?

The answer would be battery life. While running small apps like messaging, whatsapp, twitter, watching movies etc, the small cores would do the job efficiently. Even small games like candy-crush, clash of clans etc run on these small cores. On the other hand, playing graphic intensive games, decoding/encoding videos or using photoshop on your phone would be taken care of by the larger cores.

that seems logical , thanks again for your explanation

Anytime mate..

In general, the phone has maximum of 4 cores online out of 8. It could be 4 Cortex-A7 (lower power consumption) or 4 Cortex-A15 (better performance) online at one moment. Or if the phone supports big.LITTLE architechture (which I am unable to confirm at the moment), then the phone can also mix these, so you can have 3 A7 cores and 1 A15 core online or 2 and 2 etc.
As for the frequency, A15 runs at up to 1900 MHz, which is also shown on the screenshot, and A7 runs at up to 1300 MHz.

i read that there were some attempts to make the 8 cores work at the same time using some patch , but that was cancelled by samsung itself due to the overheat and the high battery consumption ....

One "BIG" A57 core always active?

Hi,
Been monitoring battery performance and CPU sleep states, and one thing I notice is that on my device the A53's spent a surprising amount of time at 1Ghz+ when the screen is on, and one of the A57 cores is always running a 384 when the device is idle, while the other 3 sleep. Is this Sony's attempt to keep the UI snappy? Having the A57 on all the time (screen on), even at that low frequency is going to use in the region of 100mW+ (which is about 4x that of each A53 core)
Can someone else sanity check my results?
I'm using perfmon, systempanel, and "floating monitors"
Perfmon can be found here: http://forum.xda-developers.com/showthread.php?t=1933284
It's also on the market for the price of a coffee, please consider buying it - great tool!

Yep sounds about right this Greek review:
https://translate.google.co.uk/tran.../2015/10/24/sony-xperia-z5-review/&edit-text=
Found that in most cases only one A57 core runs in the Z5.

Pardon my ignorance but...how much worse do you think it is to run only the big cores and throttle them from 2Ghz to 300Mhz without turning ON and switching to the little ones? (In other words...disable the big little technology and just use the best 4 cores).
We're now using the little cores more than the big ones....and that 1.5Ghz cap could be the reason of a lot of stutters.
Changing the topic, now that Google is selling Nexus devices (5X and 6P) with big little. I think they will improve this ARM technology in future Android versions (including the kernel).

The little cores will be perfectly fine for most daily mundane tasks, such as checking emails, messaging etc. The stutters you mention probably is because the phone launched just before Marshmallow and Sony are focusing more on that OS, same kind of thing with the camera. The current camera app is just a placeholder for the proper app due for release in a week or two.

In short, no. The little cores, whilst relative to the A57's are weak, they are by no means underpowered for running the UI and such. Do consider that the A53 core is faster than the A9 cores that powered previous flagships such as the Galaxy S3. Leaving one of the A57's ticking in the background is probably not such a bad idea having thought about it, as it allows fast handover when the high performance is required; I do however hypothesise that some of the stuttering might be due to threads being handed over to the A57, whilst it is running down at 384, which will be somewhat slower than the high frequency A53 core(s) the process is being passed from. It may be that we see a touch-boost or more aggressive CPU governor brought in to rectify this.
On a related note, there is a good article on the power-aware BIG.little implementation in the Snapdragon 810 here:
http://www.anandtech.com/show/8933/snapdragon-810-performance-preview/4

Definitely for performance.
If they weren't set is this fashion the UI would feel sluggish and sluggish on wake up.
Your findings sound perfectly normal/adequate, resemble a "interactive" CPU governor.

Z3+ A57 - 2 cores or 4 cores

So according android central's review, the Z3+ has two of the SD810's A57 cores disabled entirely. Only certain apps (literary a select few apps like the camera or antutu) will enable the phone to use all four A57's.
(can't post links, new user:crying
I don't own a Z3+, but I'm interested in getting one. Just curious if the Z3+ still has those A57's disabled under marshmallow, otherwise I might get a Z5.
Would someone on marshmallow test their Z3+ for me? All you need to do is download and use Trepn Profiler from the play store (Qualcomm's app, sorry can't post links).
According android central the A57's are cpu5, cpu6, cpu7 and cpu8.

According to the stats 5,6,8 were running on 0

Thanks for checking!
Ok so 3 of them were disabled, maybe that's why MM runs cooler?
If possible could you play a game or something, not a benchmark tool, and see how the cpu's behave?

In my case one was showing 0 (if I recall well, cpu7), rest were showing activity during ordinary tasks as browsing, moving through menus etc...
Sent from my Nexus 7 using Tapatalk

After some in depth investigation I can confirm that Z3+ won't use 3 of its A57 when it's gets hot specially during gaming. Only one core would work and that too at very low clock. After that no matter what you do it won't use the A57 cores. The cores would fire up only if you leave the device idele for some time. But as soon as you open Chrome the A57 cores would fire up but a low clock. This is happened in the lady update. Before that on MM even when the device was hot A57 cores would fire up. But after the last update Sony has done heavy change to the governor at the expense of performance. Even my 3 years old note 3 runs the game much faster after 5 mins into heavy gaming.
Sony should provide a performance mode option for people who need high performance during gaming irrespective of the heat. But the phone would never lag in the general applications. The only problem is that high level gaming and video editing impossible on this phone due to the A57 cores becoming inactive.

To be honest I think its actually making the battery last even less time, my z2 goes faster, cooler and much longer. Really really disappointed so far in this device and I dont know if they're going to bother improving on this.
I never used the device with mm because when I got it and added the 2nd user it gone into bootloop, so I had to flash it with the flashtool.

It's how the Big.little has been configured. How I see it though is that it's a 4 core with a boost function. Um sure the 810 Uses HMp
The most powerful use model of big.LITTLE architecture is?*heterogeneous multi-processing?*(HMP), which enables the use of all physical cores at the same time. Threads with high priority or computational intensity can in this case be allocated to the "big" cores while threads with less priority or less computational intensity, such as background tasks, can be performed by the "LITTLE" cores.[10][11] wiki

I also noticed that. 3 cores are dead under pressure of gaming thats creepy.. Im on the latest mm. Hope that they will do something with it because i can feel its getting slower in direct test with Galaxy alpha g850f (with exynos).. Do someone know if this is a feature of marshmallow only or it is included in lollipop
