The Toshiba TG01 has built-in cpu scaling which is nice to ensure maximum speed (Maybe why it beats HD2 in benchmarks?)
Does HD2 have this (I doubt it as its never been mentioned) and if not, could it be ported from TG01?
Thanks!
Bump? Is nobody interest in this?
CPU scaling doesn't ensure "maximum speed"... if there was no CPU scaling the processor would ALWAYS be running at maximum speed. Scaling slows the processor down to save power when it's not being used as heavily.
This kind of support is likely to be at hardware/OS level, so I'm sure it's going to be on the Leo.
Does neuROM not to something like that? Slows down the processor when the display is off etc.

These sort of things tend to be specific to certain OS/CPU combinations. What worked on the old Qualcomm chips probably won't work on the Snapdragon. Maybe it will, but if not it would have to be modified to work with the platform.
so now that the latest beta of siyah kernel supports enabling/disabling of the 2nd core, and tegrak already released an app for it, i just want to know the possible effects in performance/battery if you use the different options of the 2nd core app.. especially when we use the single core option.. so what will happen to our phone when we run HD games, and im sure that it will extend the battery life, just not sure how the phone will behave with only 1 core running.. and will it be bad for our phone to only run at a single core..
and also, am i right to assume that our phone has the option "dynamic hotplug" by default?
Shouldn't see much of a decrease in the performance. The sgs has a single core yet the cpu can still handle anything thrown against it. Point being there is nothing out that demands dual core performance. On another note note, hd games are not actually gd. It is just advertising point for game developers.
$1 gets you a reply
Using one core instead won't break your cpu. It gonna make your phone cooler ( ! core is running producing less heat and the heat dissipator is made for the dual core ) and have a better battery life obviously. It will, obviously too, slow down your phone, but the speed lost is to be determined. You might want to test it out to see if it's getting laggy or simply suck. As already said, the SGS I has a 1Ghz proc and can handle most of the top recent content available so with a 1.2 Ghz single core, you should be able to handle everything available, specially with an optimized kernel like siyah. And you are right, the default mode is dynamic hotplug, which use both core when needed and turn the core 1 ( 2nd core ) off when not needed.
I tried playing a little with it. The overall smootness doesn't change and i get about the same fps in nenamark2. The only game i saw stuttering a little more in single mode was Shadowgun, the others are just the same. I also have the feeling that cpu noise is reduced while playing music through headsets when you run on single.
I like the idea of switching off one core. But while using only one core this leads to a higher load on that corse. This will result in higher frequencies an thus higher battery consumption?
So might using only one core even be worse for battery life?
I mean isn't that the reason why you use multiple cores? That one does not have to produce cpu with high frequencies? I think I once read that the energy a cpu uses it proportional to the frequency squared. So it is not a linear relation. That means two cores on 500 MHz are using less power than one cpu on 1000 Mhz. Can someone confirm that? So if th os is optimized for multiple cores the energy consumptions will be less.
What do you think or know about Android. Is it managing two cores intelligently an thus reducing energy consumption or are we doing better with switching off one core?
Hi,
is anybody out there who can share any experiences with this 2nd Core app?
It would be very interesting whether it really saves battery(and if yes, is it noticeably or is it a huge difference)? Are there any negative effects in speed oder stability?
Rgds
I don't particularly care about potential battery saving, but I use it to manually disable one core while playing games which have problems with SoundPool ( see http://code.google.com/p/android/issues/detail?id=17623 ), such as Galcon, as this mitigates the problems.

I assume that the S4 Pro is MUCH faster than anything used in the xbox and ps2. I assume its faster than the 360 and ps3. Is that really the case though? The games look like crap on the current gen consoles and many mobile games are catching up. From a purely specs perspective is the Adreno 320/S4 Pro superior?
I would seriously doubt that but i don't know enough to say that for sure. Sure mobile CPUs are pretty good but they are limited by their thermal envelopes.
Compared to the PS3? NO. the cell processor is very advanced even if it's partly locked down. (there are 2-3 cells that aren't used)

Very advanced for 7 years ago. This is 2013 and the S4 Pro has more cores/ram/gpu cores. The PS3 games cant even run in 720p. Most games are upscaled from 960x540.

Can't be more wrong. It hasn't got more CPU and GPU cores. It has more RAM but the PS3 doesn't have to run Android. Also, very few PS3 games run at qHD res. One game is Black Ops, but it does this because it runs 60 FPS. Most games nowadays render at 720p or near it.
Also, I have yet to see a mobile game that comes even close to PS3 games nowadays. Maybe some mobile games look better than some PS3 release titles, but that's it.

Yes it does. The PS3 cell processor is single core. The 360 CPU is tri core. And the PS3 runs a form of Linux.
Does it really even matter? If you bought your phone as an alternative to a gaming console or handheld gaming device you bought it for the wrong reason.
Also if you want to compare specs, compare a PS3 or XBox 360 to a phone that came out 7 years ago.

There is a single PPE and 8 SPE-s. One SPE is used by the OS and one is locked.
Yes, it does run a form of Linux, but what I originally meant was that its footprint is very small, it only consumes 20-30 MB of RAM compared to Android which needs several hundred MB-s and also CPU power to run background services.

Umm i thought the Cell processor was a "7" core device at 3.2Ghz to boot. Not that clock speed is everything but it puts out 218 G-FLOPS while the 550Mhz GPU (RSX) puts oput 1.8 T-Flops. The Adreno 225 does 12.8 G-FLOPS.
http://www.anandtech.com/show/6330/the-iphone-5-review/11
According to the that page, the iPhone 5 GPU is similar to the Adreno 320 and that does 19.2 G-FLOPS. WAAAAY less than the 1.8 (or read 1800 ) T-FLOPS of the RSX.
VRAM data rates are ~20GB/s vs 8GB/s
So yeah, guess we can say that's done for.

Pretty sure it's more powerful than either the PS2 or Xbox, but there's no way it would ever emulate them if that's what you're getting at there
Not to mention, the Android OS uses a lot of resources, unlike a simpler console such as those
No way does the RSX put out 1.8 Tflops....
It's basically 6800SLI which gets nowhere near that, the 580 doesn't even get that lol.
The Cell is an overhyped CPU that failed to deliver and in reality CPUs like the 360s Xeon and the I7s we have today are so much better for gaming. Developers just complain about the amount of code the Cell needs compared to conventional CPUs and how it takes too much time. Doesn't matter what you say about it in theory, in practice it costs too much money to develop on and it cost Sony the console war. Fact is we've not see the PS3 out perform the 360, the GPU inside the 360 can push more pixels, has access to more memory too. Games like uncharted use so much trickery to make them look good, I don't understand why people make a big deal out of it, have you seen the obviously jpeg like skyboxes all over it?
Graphics wise the phones are already there, what they lack in power they make up for in memory and new shaders and features to make the games look better. Mobile GPUs also push games at higher framerates and use AA which consoles lack most of the time due to memory constraints. Instead their games use post processing effects which blur everything out and make it look ****. Also mobile games run at 60FPS where as most console games are around 30fps or even lower.
CPU wise mobiles are getting there but still far off, we see the next gen of Arm chips getting close to the I3.
The biggest constraint of the Mobiles though is battery.

Give it up already. On paper the N4 is great and all for what it is, but it can't compete with a gaming console. Try hooking up your phone to a big screen hdtv and see how it compares graphics wise to a gaming console if you have one. After all, the SGS4G doesn't have a disc drive on it so I don't know how you could play a PS1 game one it. You must only be playing pirated games via a 3 or 4 inch screen to come to the assumption that a cell phone comes close to any of the current gaming consoles graphics wise. Afterall, there is a reason they make cell phones, dvd/bluray players, video game consoles, tvs, etc... They each have their own benefits.
Lets be honest, PS3 games are absolutely shocking. They have so much screen tear, not to mention the actual graphics are completely and utterly awful. It takes an age to load, even it's own dashboard. Xbox 360 is better but still, consoles we have today are absolutely light years behind PC's and even the processors we have in our phones outshine them.
You can quote all the nonsense giga flop teraflop data you want, you would be all talking out your behinds because consoles struggle with the games they have, and with skyrim as an example, are completely and utterly chopped down to run, when compared to the unlocked PC versions with the proper textures.
I have yet to find a PS3 game to run in 1080p which is what it should be coping with, and the 720p games are awful both performance wise, and graphics wise.
As for mobiles on a big screen tv, the LG optimus 3G hooked up to 40 inch hd tv gaming is absolutely brilliant, look it up.
Xbox 360 is much much faster than the PS3 and actually does have better graphics it can handle and probably gives the Nexus a beating on the graphics side, but loading and general useage as a pc and it'd be useless.

Regarding GPU power: Nowadays it's still ~ a factor of 10. It is a really rough number but I often measured something like this when comparing GPU performance of iOS/Android devices and consoles/mid PC systems. Modern games still do a lot more than mobile games regarding rendering (shadows, global illumination, screen scape effects like SSAO, etc, etc). But mobile GPUs will get better and better. See e.g. the roadmap from NVIDIA and the comparison with current console generation:

Actually PS3 has v-sync enabled for lots of games which means no screen tear.
And no, the Xbox doesn't have better graphics. If Uncharted wasn't enough, take a look at Heavy Rain or The Last of Us.

Hey friends,
I love running the phone on condensed font so I can see more information on the screen.
I'm not sure but it feels like it slows down the phone at this mode because it needs to display more at the same time.
Trust?
Interesting been so long since the swapped but can't recall any noticeable difference in performance
Sent from my SM-G935F using XDA-Developers mobile app
I have the same feeling as the OP with my s7 edge. Anyone know if there's technical validity to this or just our imagination?
I didn't notice on my S7 edge because I've been using it in condensed mode since the beginning, but I definitely noticed a small performance degradation and choppier scrolling on my Xperia Z5 when I was running it @400dpi instead of the stock 480dpi.
I may be wrong, but I assume the fact the phone has to render more stuff to fill up the screen (more text, more pictures, more UI elements, etc.), as everything is smaller, may be the reason.
Can't really notice any difference. Our phones are powerful enough to even render 5K resolution at quite smooth speed (tried it). So performance between condensed and normal mode would be noticeable only on older devices like S3-S4.

Yeah but its not all about power. Its about how you manage power. Most of the lags,stutters occur because of juuust a tiny latency in cpu frequency scaling or switching on/off other cores of cpu. You can make a cpu jump faster and at lower load to a higher freq, but this wil increase power consumption. So I believe in theory, a phone which has more single core power but less cores (or multi core power, and yes I'm looking at you iphone 7) , will perform better on simple task and worse on harder task like 5K resolution rendering...

Well said .
Hello guys..
I have this phone which has a quite good Specs..Though when I install a game, there's some lag
I'm running on Nougat 7.0, I've installed asphalt 8 and there's a lot of lag in the main menu, but that doesn't matter cause I deleted it
now I've installed PUBG Mobile and it's a very exciting game and I'm running on the lowest graphics and I have free ram and space But it lags a lot. I've tried this game on Galaxy A5 2017 on medium (balanced) Graphics and It runs like a charm.
Is there anything I can do to make the game on my device faster with no lag? And why does the game lags anyway on my device which has 3GB Ram?
It's not the RAM that matters but also the GPU. A 2016 uses Mali-T720 while A 2017 is Mali-T830, thats the difference.
I suggest you use Game Tuner from Samsung and adjust the resolution to 55-80%
OK, the hardware is different, but other than that...
A 2016 (info from A5 but should be close) That GPU should be enough to fit the first game on high (maybe outdated), and the second on low (untested). For context, the CPU/GPU is like a motor, running at various speeds, 'weights it is carrying', and power required to maintain that speed (the heat output also scales with this). Some are simply better than others. The Game Tuner's HW performance (CPU) isn't or wasn't available. The customfrequencymanagerservice lowers the CPU/GPU speed for games, also increasing the battery life and lowering the heat. Search the logcat for "limitGPUFreq" "limitCPUFreq" "SIOP_ARM_MAX" (not the tag, but the content). Other than that, the CPU cluster 0/CPU cluster 1/GPU lowers its own speed at 86c (not bidirectional). Optionally, at the cost of heat and battery life, downgrade the game tuner and game optimizing service to whichever version has the apps category feature. Then select the app, then non-game. Lower the resolution to the default 75%. A limit is still there but not as much as before, and looks more like thermal throttling. If rooted, the max speed can be customized in /sys/power/cpufreq_max_limit for the CPU, and /sys/class/misc/mali0/device/dvfs_max_lock for the GPU. Set permissions to 644 to maintain the max speed (until the CPU/GPU lowers itself). Watch the temperatures. If it's too hot, reduce the limit. Maybe an alternative to root is debloating but the speed can't be lowered if needed.
Temperature sensors are here:
/sys/class/hwmon/hwmon0/device/temperature

/sys/class/thermal/thermal_zone1/temp
/sys/class/thermal/thermal_zone2/temp
etc.
A 2017
The customfrequencymanagerservice applies to the CPU, up to 1794Mhz (HW performance). May lower with what looks like thermal throttling.
Does not apply to the GPU, which throttles itself somewhere around 76c from 962MHz to 845MHz.
Yep. Been playing PUBG Mobile on my A5 2016 on LOW graphics and HIGH frame rate (fps setting) for around one month and it does NOT lag. Although the transitions in UI of main menu is not as fast but the gameplay is super smooth and does not lag. Maybe it's because of your phone slowdown over time (I just factory reset my phone 6 months ago) or because the A7 has more pixels to push so it is more taxing on the GPU.

I tried to set a game to a *non game* but game tuner doesnt let you switch anymore between them
I have A3 2016 and playing 20fps in game. ( Medium fps setting). If i select high frame rate my phone is heating much then my display doesn't work stable its sensitivity sucks when phone heats. It's not lagging to the last 3 circle. But if i see an enemy my device lags a lot and my fps drops 5-10 so i died more times bcz of the fps drop. Gameplay is best in Lineage Os 15.1 but it has overheating issue so display sucks when device is overheated.
