Not in the sense that the A5 is a dual-core. The Mali-400MP has four pixel shaders (what they like to call quad-core) and one vertex shader. Tegra 2 has four pixel shaders and four vertex shaders, which they total to 8. Tegra 3 has 8 pixel shaders and 4 vertex shaders, for a total of twelve. They aren't cores at all, that's just BS that nVidia started a while ago to take a cheap shot at Intel. :)

On the other hand, the SGX543MP2 effectively has two complete GPUs - each with four pixel shaders and four vertex shaders. Hardware wise, it's pretty much equivalent to taking two of the GPUs used in the Nexus and sticking them together. Albeit at a lower clock rate, I imagine.

Not that it really makes that much difference for mobile games - art style can go a long way towards making a game look amazing on low-power hardware. The iPhone 4 has/had some pretty amazing looking games, and you'd struggle to find a higher-end Android these days whose GPU doesn't absolutely smash the iPhone 4. :D
[Samsung Galaxy Nexus] pukemon:
Im well aware of this. The op probably doesnt know or care. Hell, if you get a desktop class gfx card youre looking at upwards of 300 "cores" and more. It boils down to different architecture and marketing of course. The 540 is a capable mobile gpu. Nobody is quite sure how it handles higher resolutions though. Lots of cpus/gpus have quoted specs saying it can handle this and that but when you push the theoretical limits performance goes south quickly. And the 543mp2 is overkill currently. Probably a major factor of why the iphone 4s is getting ****ty battery life. Who wants to brag about how ****ty the battery life of their phone is though? These days 4 hours of display time and using your phone all day is good.

[Samsung Galaxy Nexus] ssconceptz:
The Galaxy Nexus is dual core.....
[Samsung Galaxy Nexus] CoNsPiRiSiZe:
well whatever u do don't read what we're actually talking about... not the CPU...the GPU
[Samsung Galaxy Nexus] pukemon:
Dual cpu. Single core gpu.

I invented cyberspace. You're trespassing.
[Samsung Galaxy Nexus] Chirality:
It's not really correct to call the GPU "single core". A GPU is a parallel processing unit, what matters is the number of pixel pipelines, the number of shader units, the number of ROPs, etc. In fact, performance should scale better using a GPU that has 8 shader units on a single physical core than a GPU that has 4 shader units each on two physical cores. The only good reason to spread GPU processing units across multiple physical cores is ease of manufacturing. Usually you would expect the next generation of GPUs like this to merge the physical cores into a single physical core with the same total number of compute units.

We are talking about GPUs here. GPUs solve what is called an "embarrassingly parallel" problem. Here, twice the number of cores usually does mean twice the performance.
[Samsung Galaxy Nexus] qreffie:
There are no mobile games in existence that really make me care about my phone's GPU and I highly doubt there will be in the next coming year or two. I doubt my phone will ever draw my away from my PC or gaming platform at home and when I'm away the most hardware intensive game I play is Plants vs Zombies, Fruit Ninja, or Words With Friends. And that's only after I've looked all over the internets for something else to do other than game.
[Samsung Galaxy Nexus] nesx87:
question.. how would you expect the higher clocked PowerVR SGX 540 perform vs the galaxy s 2?
[Samsung Galaxy Nexus] Jasonhunterx:
Well it doesn't seem to matter galaxy s and nexus has same gpu at lower speed an I haven't seen game it can't handle an then add 1 gb of ram with better CPU ur all good
[Samsung Galaxy Nexus] player911:
If you look at droidgamer, you'll find lots of crazy high end games are on the horizon. Most take advantage of the Tegras which currently are beasts. The G2x by LG is such beast. Tegra 2 powerhouse. Easily bests any game made today and in the future.

Tegra 3s are due out around the first part of next year but probably nothing subsidized in the US till next Christmas or early 2013.

Even still games are made to run well on popular hardware of today. Adding more power is currently overkill and only adds bonus eyecandy. I expect upcoming games to be playable on any high end phone, Nexus included.

Plus ifones are late to the dualcore game. While the GPU is nice, no ifone user will know about anything past the words they are regurgitating.

I am concerned about going from a powerful G2x to a GN. I'm getting mine through work to save on a personal cell bill, but I hope everything is at least moving in the right direction.

I'd trade my 8mp for a 5mp with an instant shutter because I have a kid I snap at all the time. Games are luxory but I do have a tegra 2 Transformer that I do most of my gaming on (outside passive games).

G2x - 2.3.7 CM7

Transformer - 3.2 Revolver OC/UV

does the iphone4S have dual core GPU?? really?

i tought it only had a dualcore CPU....

iPOOP!
[Samsung Galaxy Nexus] Jebus99:
The problem with all the core nonsense for GPU's is the lack of a unified architecture. What we're comparing is similar to what we did before the Geforce8 and Radeon3000 series, in that there are individual pixel and vertex shaders. Its completely BS to call either of them "cores" if we use the same word for CPU cores. By that regard, my ATI 5850 has 1440 "cores", which makes any quad core processor seem crap, no?

As pointed out, GPU's are still in their infancy in the mobile world - hence the lack of a unified architecture *but* ARM is bringing one in their next gen Mali GPU so we should finally start to go towards a more reasonable comparison of GPU's soon. But for now, its best to ignore what "cores" a GPU has but look at the number of Pixel shaders, vertex shaders and ROP units (render output units). Essentially, PowerVR is aiming for a even balance between pixel:vertex shaders (hence why the MP2 has 8 of each) whilst Nvidia think that the major limiting factor is the pixel shaders, rather than doing complex geometry via vertex shaders, and that's why they push for a 8:4 / 12:4 ratio. Whether that's a smart idea or whether it will limit Tegra vs PowerVR, it's hard to tell yet. That being said, expect a massive change when we jump to the unified architecture of Tegra4/new Mali/new Adreno. Until then, take the "cores" with a grain of salt. The only legitimate use of the word core is with the PowerVR SGX543MP2/ MP4 where the 2 and the 4 are representative of 2 and 4 complete SGX543 GPU's stuck together, but each of these are clocked lower than an individual core, presumably for heat/power issues. And also remember, just like in the desktop world, drivers make a world of difference when looking at performance in games. It's pretty hard to see who's better at that yet either, but Nvidia might hold a better hand with their experience from the desktop/laptop market. This is probably the best time if you like observing massive evolutions in graphics tech, but its a crappy time for consumers since the next best thing comes very very quickly.

Edit: For anyone who's interested, Anand had a great write up comparing the architectures here. Some quotes to justify:
[Samsung Galaxy Nexus] Tornlogic:
Ask the iPhone pukes if they have something that matters. Good call quality and 4g
[Samsung Galaxy Nexus] Nospin:
MUCH bigger screen, 4G, ICS, dual core processor. And you won't have all those iOS 5 problems going on right now.
[Samsung Galaxy Nexus] Tornlogic:
Exactly. Do a screen size comparison with their silly little toy. Screen resolution would be iceing on the cake. I would be embarrassed if I were them.
[Samsung Galaxy Nexus] k_nivesout:
I thought this was a thread on GPUs, not iPhone vs Nexus.
[Samsung Galaxy Nexus] CoNsPiRiSiZe:
Some are using the iPoop as a example to compare and show the differences from "dual core GPUs" to "single core GPUs"

Its just a good example that's all.
[Samsung Galaxy Nexus] k_nivesout:
I understand that, but the last few posts have just been iPhone bashing which really serves no purpose in this thread.
[Samsung Galaxy Nexus] CoNsPiRiSiZe:
Well some people just love to bash iPhones. I guess we all have the desire to prove our opinions better or our products better. The iPhone Is truly a great device for so many people around the world, so I guess some might b intimidated or whatnot.

Or maybe they got carried away :P

Either way iPhones will always be flamed. at least on android forums :P
[Samsung Galaxy Nexus] k_nivesout:
Very true. I guess it just gets on my nerves sometimes when people derail a discussion just to bash Apple. Don't get me wrong, I love android, but the fanboys on either side can get on my nerves. If you want to bash Apple, fine, but go find an apple vs android thread or something, last time I checked this was the Galaxy Nexus forum. If it's discussion on iPhone 4s GPU vs Galaxy Nexus GPU, then yeah, but I really don't care to read peoples' personal opinions on iPhone vs Nexus in a GPU thread.

/rant
[Samsung Galaxy Nexus] hellcatrydr:
+1.

The OP just asked a reasonable question & the flame job starts right up. I've got no respect for that chit. It makes us look like bigger poofs than the fruit boys.
[Samsung Galaxy Nexus] Sjael:
Tegra 2 is 4:4 (8) and Tegra 3 is 8:4 (12,) unless you are talking about something different.

And just to add to the fun, Tegra's shaders actually are unified shaders (based on Fermi shaders, iirc,) but half are locked into either role. :D

ARM definitely values pixel shaders more highly, with their 4:1 approach in the Mali-400.
[Samsung Galaxy Nexus] vash1053:
I wonder if phandroids realize they're exactly the same as iOS fanbois. Just on the other side of the fence. It's a little sad, and pathetic.
[Samsung Galaxy Nexus] ckochinsky125:
hahah so funny and it does seem the OP is one of those who feels good about themselves only if their phone has all the specs they can tell to their cronies err I mean friends.
[Samsung Galaxy Nexus] Bikram:
Yes I do feel good about having all the horsepower under the hood. Bit for show off and bit for future proofing. Anyway, lets not discuss about my habits and character.

SO going back to the topic it seems like PowerVR540 is good GPU but just one generation old but still can do its job. Putting it in HDMI shouldn't be a big deal at all.

The games which are made for tablets are forTegra 2. And there are no phone yet with Tegra 3 yet (except this one)

Thanks guys for all the infos. I was pretty convinced with PowerVR540.....then when I learned that G.Nexus doesn't have removable sd card, then I decided not to buy it.

[Samsung Galaxy Nexus] lorddart:
Hey guys maybe semi off topic but is it just me or does dungeon defenders run smoother on an ipod touch 4th gen/ipad than the recent dual core phones that are out on Android? I would never switch to them for a phone. I can't stand apple but gotta say I'm a little disappointed that I haven't seen any Android phone compete. I have not checked out an sgsii. But I'm hoping the 'restructuring' with how ics runs things helps this...
[Samsung Galaxy Nexus] player911:
LG G2x plays dungeon defenders fine...

G2x - 2.3.7 CM7

Transformer - 3.2 Revolver OC/UV
[Samsung Galaxy Nexus] lorddart:
Huh pretty sure I've played it on there and it was glitchy like other devices I had one for a while. Hmm. Have you played it on an ipod touch 4th gen or newer device? Still seems smoother and without crashes which I also experienced on Android. I'm in no way a fan of apple in fact I hate them. But I sure wish/hope ics software end will help our devices run smoother. I can't stand itunes, screen size, and their business model, or pretty much anything about apple. Ha but they are smoother for now in my experience.
[Samsung Galaxy Nexus] jivemaster:
The GPU in the Nexus will be more than sufficient for what it's there for - hardware acceleration of the UI.

Gaming should still be ok on the Nexus. However, there is no competing game wise as far as iPhones go, they have it hands down with GPU power and dev support. Because Android doesn't have a huge game scene, an epic dual core GPU isn't at all necessary.

That said, the SGX540 is no slouch, especially at full clock speed like that found in the Galaxy Nexus.
[Samsung Galaxy Nexus] lorddart:
This... Is what I was thinking... Sadly it seems a bad natured beast... Imo if there's no games developed for Android needing ridiculous gpu performance the phone won't have the support and vice versa if there's not a device that can run something why make it? I honestly will hold on to my ipod touch for games and use my phone for anything phone related hoping ics gets rid of the infrequent lag and hiccups we have. If the hardware acceleration makes ADL'S smooth I'm happy. I decided that carrying a massive phone tries too hard to meet the demands of both phone and tablet. I'll keep my tablet for gaming and enjoyment and my phone for smaller functional tasks
[Samsung Galaxy Nexus] Nebucatnetzer:
It's like PC vs consoles when it comes to gaming. It's easier to develop for one fix base then for many different configurations that's the reason why there are more and better looking games on iOS devices and why the same games are running smoother.

[HTC Sensation] kaof:
so after searching the forums i found:

1) faux clock

2) system tuner

3) init.d scripts

with (2) vdd values dont persist & revert to stock after a while for some unknown reason.

with (3) the vdd table doesnt change at all, except when the same commands in script are entered through adb.

i havent tried (1). i've had the most success with (3), but having to do it through adb every reboot is a bother. how are you guys doing it?
[HTC Sensation] gol_n_dal:
I'm using FauxClock 0.8.0 and resetting if it reboots.

I like the fact that it resets the UV on a boot, so that if I've UV'd too low it resets to be usable on a boot.
[HTC Sensation] yungyeh:
I think fauxclock 0.8 is your best option. 0.75 has some compatibility problem so do not use it.

If you want to use a scrip. I would put the corresponding code in the /etc/init.post_boot.sh

echo "-50000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

Reboot and then check the vdd table.

If init.post_boot.sh does not exist, do the following in the terminal emulator

touch /system/etc/init.post_boot.sh
chmod a+x /system/etc/init.post_boot.sh
vi /system/etc/init.post_boot.sh

After successfully creating the init.post_boot.sh, then write this in it:

#!/system/bin/sh
<YOUR COMMANDS GO HERE>
[HTC Sensation] kaof:
Scripts make a cleaner mod, try it someday! :D

You can UV individual frequencies, and after you get it right it's just set-it-and-forget-it.
[HTC Sensation] kaof:
Lesson learnt - UV scripts in system/etc/init.d don't work, but editing init.post_boot.sh does!

Works like a charm, thanks so much! :)
[HTC Sensation] Kohr-Ah:
Have to make sure that the init.d scripts have the right permissions for them to work ^_^
[HTC Sensation] kaof:

[TouchPad General] chrischoi:

[TouchPad General] chrischoi:

[TouchPad General] eppyramot:
I too felt webOS looked better than CM7. I was using 160 and 140 for LCD density. Then I upped it to 169 and it looks much better to me, also i installed the ICS roboto font and that looks much better than the stock g-bread font. Also for some reason when i went the other way and took LCD up to 169 suddenly I could get a few more apps in the market that seemed to be missing before (I remember early on with my Nook Color the LCD density affected the market as well).

Also there is a market app "hp touchpad wallpaper applier" that lets you use high res wallpaper in CM7 which looks much better.

[Captivate Q&A, Help & Troubleshooting] studacris:
Red cwm means it's a voodoo lagfix enabled kernel.

Just go into recovery, voodoo, disable lagfix then reboot. It will stay on the kennel splash screen for a while, You will hear female robot voices as the lagfix disables.

Then you should be able to just flash whatever you want unless you're going to a Samsung gingerbread ROM, then you would need Odin or heimdall to flash new bootloaders, but cm7 does not require that step.

[Motorola Droid X2] stevenjcampbell:
Don't know if anyone else has played with it, but if i need a FAST charge and i can afford to do it, i use setcpu to turn the max CPU as low as it will go, which is 216mhz and let the phone charge.

I am using Battery Circle on the stock moto ROM with as much blur removed as i can, and if i let it sit with this CPU speed forced, i will see it go from 20-80% in as little as an HOUR...

restarting the phone with the battery bug can get me even higher, maybe upper 80% on the battery.

Try it, it really works! I have played with a profile that sets it as soon as the charger is plugged in to around 400mhz but the phone i find lags and it is hard to use, so i just plug, launch the setcpu app and crank down to 216hz

when i am done i unlock the phone, and put the speed back to where ever i need it to be.
[Motorola Droid X2] iCurmudgeon:
Wouldn't powering down the phone while charging achieve the same results?

I've had a lot of problems with cranking the cpu speed down to the minimum -- a lot of laggy performance and some lockups that required a battery yank. In fact I use setcpu to force the minimum speed on my phone to 456 MHz to avoid any such problems.
[Motorola Droid X2] stevenjcampbell:
It really depends on a few things.

Your launcher, what the phone is trying to do while idle, etc.

Example, i find that if i have a lockscreen pattern that needs to be drawn i will have to be patient with it.

and obviously powering down the phone works.

It also makes it so your calls go straight to voicemail and you miss all sms messages.

I use my phone for business and i cannot have that problem, so long as i use fast reboot to "wipe" things out once in a while nothing bothers me putting the speed down.

You can charge lower, around 500mhz.. it also helps.

I think it has to do with the voltage being used to power the CPU being very low that helps it charge so much faster.
