Epic 4g vs tegra 2...

So I like many of you am thinking of jumping to tegra 2 within the.next year. I personally build pcs for myself and have always been a loyal fan of geforce gpu cards and nforce boards. So when I learned of tegra 2 I nearly creamed my pants. But after modding my phone running midnight I've turned this into a beast. Scoring 1100/2700 in smartbench and 2000 in quadrant I went looking for any benches tegra 2. I found a quadrant bench of the bionic and it scored around 2200. I know benches mean nothing but these scores are pretty close. What do you guys think are gonna be some advantages you see speed wise with tegra? Im trying to determine if the jump would be worth it...

Tegra 2 will murder Epic's gpu,i would say its 3-4 times more powerfull.But who want Tegra without Super Amoled?lol,not me.

Good point lol I know samsung sucks at updates but I think if they get the sgs2 right ill be looking forward to it. Samoled is amazing. I want a 42 inch samoled tv. Wow I just really thought about that and it sounds amazing.

The Tegra 2 GPU is not 3-4 times more powerful...if anything the GPU is where the Epic is closest to the Tegra 2..(of course the Tegra 2 GPU supports some nice new protocols but in terms of raw power)

Here is the things to consider besides quadrant being flawed:
1) The Tegra 2 right now is not optimized and is not using the dual core..its only using 1 core..Dual Core support and optimizations will come with Honeycomb..
2) The Hummingbird is also not optimized and will be optimized in Gingerbread
3) The GPU on the Epic dithers at 24bit while Tegra 2 still does 16bit dithering...
4) The GPU on the Epic is FPS locked...so its definitely capable of more..
Its kinda hard to say what the performance will be of both once the smoke clears..but the Tegra 2 is 40nm and is based of Cortex A9 which give it a lot of advantages..the disadvantages would lie in whether or not applications would support dual core and if they will when and how efficiently..
I estimate though Tegra 2 would definitely win on CPU processing from 25%-100% depending on whether or not it can use both cores..and in terms of GPU it would be around the same to 50% better depending if there is dual core support or not...(assuming that we unlock the FPS and find a way to make it dither the same amount of bits)
Edit: Forgot to add a conclusion~~
Conclusion is that a Tegra 2 is definitely an upgrade BUT until Honeycomb comes into play we would definitely be competitive...beyond that we won't be a slouch(I mean people still use EVOs even though ours is superior by a good margin)..but its no question Tegra 2 will surpass us..
Oh and on the Nvidia tibit...I am pretty pissed at them after what they did with the laptops..they have been serving faulty chipsets for laptops for YEARS and bribing manufacturers to use them..which has me pretty pissed...even though I hear latest chipsets 400+ series are ok..but I probably won't be buying a nvidia laptop for a while..desktop gpus are ok with me though..

Usually TVs tend to be Passive Matrix OLED and not Active Matrix OLED..anyways..that said I have seen an OLED TV at CES 2011..Don't now exact size it was as I viewed from a distance and had a person distracting me..I think it was 32"-46" somewhere there..and I'll tell you this IT WAS OUT OF THIS WORLD...or more precisely in this world..it was like looking through a glass window and they could pop out any time..thats how realistic it looked...I mean those 3rd TVs are suppose to "come out" but I think thats over-rated..look at an OLED TV and thats where its at..it was simply amazing...

That is true of all phones except the razor. That was one well made phone, even see ones at least based off them these days. Those used to not break, remember when cell phones didn't break daily?

I'm sure soon the quadcore in the new ngp psp is going in a phone.
I just doubt seriously that it makes much of a difference at all as android at this point is not capable of running multiple threads from my understanding. The Nvidia GPU in the tegra 2 phones is pretty much on the same performance level as ours so thats not even a factor.
The rumor mill has GB offering up true multi core support on the phone, we will see how that goes, because the rumor mill had froyo supporting it too.
Multi core CPU's are awesome if you are endlessly running multiple cpu intensive tasks, on your phone I doubt you will be.

Hard to say really...there really is no benchmarks or live phones to tell..
The Tegra 2 seems to support more new specs/features on their GPU...the Orion will be bundled with the MALI-400 and the snapdragon has its Adreno which seems to be promising performance on par with our current Hummignbird but will have a 1.2ghz dual core which might help it in cpu (Though Tegra 2.5 will come this year too with 1.2ghz), the OMAP chose the SGX540 which is hard to say how they will utilize it..
See its kinda a mixed bag...as we don't have any phones to try out..
IF I were to guess out of all the Dual cores this year..the best performance would either be the Tegra 2.5 or the Orion..:/

Multi-core support comes with Honeycomb :/..but yeh the 4 core CPU and a SGX543MP4+ does look rather sweet on that PSP..

I could write a monster post here, since comparing SoC architecture is a hobby of mine.
But, I'm tired, so I'm just going to drop links and say a few words.

http://www.nvidia.com/object/IO_90715.html
Obviously NVIDIA's stuff has to be taken with a grain of salt (it has a certain amount of marketing spin thrown in) but thus far has been fairly accurate when compared to actual performance numbers.
Samsung is using Tegra 2 (we've caught them accepting orders for large numbers of Tegra 2 processors) so Orion is either still in the works or has been placed on the backburner. TI is prepping their OMAP 4400, which hopefully will feature some tweaks (not something TI is known for however) to keep it competitive with the fairly hard-copy Tegra 2 ARM Cortex-A9.
And let's not forget Qualcomm. They may not be technically using Cortex-A9, but with their license to customize the ARM instruction set and CPU architecture as they see fit (something that NVIDIA, Samsung, and TI haven't paid to do), they have the ability to modify their SoCs to remain competitive, no matter what the other guys do. Their only major drawback is the time and money they need to spend on R&D.
Alright, I didn't want to write a book so I'm going to stop myself here. If you want to see me rattle on for pages about this stuff, read this thread: http://forum.xda-developers.com/showthread.php?t=907182

Runs exactly the same as it does on my epic, I'm not sure the point with that?
gTen we will see if its there when its released. Until then all those dual cores don't do much.

We pwned the tegra 2 in games **GO SAMSUNG**

Nexus S uses the same SGX 540/S5PC110 SOC.

***notice on the optimus x2****
the test is not fair.
the fps limited on most devices is 60 fps
the optimus x2 has uncapped fps rate

Not exactly pwn'd but we held our own against the big boys and their fancy dual core's.

I wouldn't expect dual core to help in games at all. Overall phone performance running multiple apps could be a big difference. Not to mention nothing is coded to take advantage of dual core right now either.
I don't think dual core is going to help much right now, and I am in no rush to get one. However, when things start getting optimized for dual core I may become more interested.

Im sorry, where did we beat the Tegra 2 at all? I'm not seeing it.

I would definitely not get the atrix only cause Motorola locks them down to much. I would wait for a dual core till later in the year when some.better ones come out.

Yeah, uh, noobnl, go back and look again man... we didn't pwn Tegra 2 in those tests. The Tegra 2 GeForce GPU has been proven to outperform our SGX540. Not by an insane amount, but consistently by a reasonable margin. The only reason we beat the Atrix in some tests was because it runs at a 540x960 display to our 480x800. The Optimus 2X did better than the Atrix because it's running at 480x800 as well.

I fail to see where we pwned the Tegra 2, or even come close, but it's cool to know that the Epic is still pretty competitive.

Could a CPU test be say zipping a large file and time how long it takes between phones?

tegra would probably kill us in that test, but in games and things like that we are about even.

Do you think we'll get locked out of some new games that are "dual core only" even though or phones should handle them?

I'm a bit torn on this issue. I'm very happy our phone held it's own (and it did), and I'm certainly aware that almost no app take advantage of the dual core yet. However as a very heavy multitasker, it'd be nice to get rid of that lag between 'switching' applications (which may or may no need to be reloaded into memory). Although I wonder if the nexus s/epic had 1gb of ram if I'd still feel the same way. I feel like additional RAM (which the atrix has) might be more valuable than the dual core. Just my 2 cents...

If I had to guess, we are absolutely going to get left out of new high end games. There are games out there now that are Tegra2 only, so even other dual cores will not be able to play them. Its looking like the market is going to be fragmented beyond belief by summertime. I hope developers don't continue to develop for specific SoC's, because that would harm the market more than it helps.

just like PCs. we wont see improvement till apps are made for dual core

I swear, Noobnl, you ALWAYS say you're leaving, then surprise everyone by making a new thread. LOL

I know it's disappointing, I'm hoping they only give them an exclusive for a little while. And I thought Android was supposed to be heading away from fragmentation . I honestly think they're going to kill Android by making the phone's lifespan extremely short if they keep heading in the direction they're going.

Well things to consider is the FPS cap and whether or not its being dithered as 16bit or 24bit :/..spec wise..we should be on par in the GFX department to the Tegra 2..
I personally dont see much reason to jump to dual cores yet..mostly wit quadcores coming en of the year..sure its an endless cycle..but at least by the more apps would exist that can actually take advantage of those cores...

[Rumor]Samsung Galaxy S III is powered by Exynos 4412 Quad-core at 1.5Ghz

That would be very nice. A little sad I couldn't upgrade to the GS II but I think I can shell out for a new phone next year and a quad core Galaxy S would fit the bill.
I kinda want a galaxy Nexus, I missed out on the N1 so I do want a pure google device but samsung just gets it so right. Can't wait to see what they do with ICS.

Then don't upgrade! you forget the other millions who didnt update this year and will be looking at 2012 for the latest and greatest. Where is the sense in wanting an Apple like crawl in progression. Android gives companies like Samsung the freedom to concentrate on the hardware. It can only be a good thing for the consumer.

While I do agree that it is somewhat pointless at this point in time, it's a common misconception that newer CPUs = more power usage. By that logic, a Core i7 will consume more power than the Core 2 Quad, which it does not.
CPU manufacturers control power consumption in a number of ways. The most common is a die shrink, manufacturing the CPU at a smaller level. The Exynos is a 45nm chip, and the next generation is supposed to be 28nm. Thus, we can expect power consumption to stay the same, or even decrease.
The other way is through the use of core gating. The OS simply shuts off the cores that are not in use, and wakes them up when they are needed.
Hopefully this helps to clear up some of the misunderstandings regarding CPUs and power consumption.

quad core has already been stated to be more battery friendly and the tegra3 chips is very clever only using more cores when needed and even having a stealth 5th core for mega low idle speeds
obvously the exynos is not a tegra3 but i am sure samsung will do some clever stuff too
quad core will be awesome , i am happy with my dual core sgs2 so wont upgrade for a while ive also bought extras etc so its not worth upgrading for me , however that doesnt stop quad core from being gooooooooooood
have you seen the gfx power it will bring , the extra camera capabillities it allows the manufactuers to use , the speed that the browser will work , how smooth the ui transisitions and scrolling will be even when multi tasking , it also brings support for up to 2gb of ram which alone is great stuff everyone knows the only thing better then ram is more ram
i think if we want our mobile to be proper mobile computers connected to bluetooth keyboards and usb hardrives then linked up to hdmi or dlna while doing back ground tasks , followed by some high end intensive 3d gaming with a bluetooth pad over hdmi while still doing background tasks , encoding high quality media on the fly and editing it without having to wait an age for it to finalise then qua core is a great thing as is the way that tech is moving so fast
the only problem i can see is fragmentation as things move so quick
its got to make it hard for devs etc which in the long turn could damage the platform a bit , however i am sure it will come to the point it will smooth out and tech wont accelerate so fast , maybe? lol
nvidia have a road map and it shows that they will be releasing a new cpu/gpu combo each year for at least the next 3-4 years before they think we will be at mobile maximum potenial , so get ready for this tradition to carry on for a while yet

Sadly I think this fragmentation might become a very big problem in the future, and is one area where Apple is unfortunately right.
Look at PC Gaming. A lot of people buy PCs not knowing exactly what the PC they bought at capable of. When it fails to run Battlefield 3 at an acceptable framerate they are not going to be happy.
For us techies, it's easy to know that you need at least a GTX 560Ti or something, but for Joe Sixpack out there they obviously don't know these things.
I think perhaps Google should enforce some sort of system requirement rating system. Give it a number scale to make it simple. So maybe the SGS2 scores 9/10, and Contract Killer requires a phone with at least 7 to run smoothly. So Joe Sixpack who bought a Galaxy 3 GT-i5800 that scores a 3 doesn't get all pissed off.
Hope I'm making sense here.

Nah fragmentation will be fine. Pc is still the choice for gamers over Apple mac, not including consoles. Transfer that to mobile phones, and as long as the android mobiles become popular enough, games will be great for them. Everyone will just know they have to have a good mobile just like their pc.

I read somewhere it would feature the AMD's new 8 core bulldozer CPU with nVidias GTX 590 in SLI.

i dont really understand people complaining about fragmentation. Android isnt a phone, it isnt a manufacturer, its an operating system. Do people complain the laptop market is fragmented because some computers are on xp, vista or 7? Some are on faster processors than others? Did people ever complain that symbian updated on some phones but not others?
I just dont get it, Id rather new phones/tech come out than only one release every 18 months.

Who cares? My upgrade isn't due until 2013... When I will get the top of the line handset again. I'm sure that model will be usurped within 4-6 months too.
Maybe we should all keep our phones in their original packaging like toy collectors, so they can't contribute to the disastrous fragmentation issue.
The actual effect of this media-inspired phenomena on consumers is negligible.

LOL sorry - had to point out the galaxy s III still has an 8mp camera. =p
Almost sounded like the Samsung Nexus with the 5mp camera... ahaha.
Just kidding. The phone should be solid. =)

Android phones vs iPhone is basically like PC vs console since PC has a billion different hardware and software configs where as a console as 1 (There are a few iPhones but you generally only support the latest 2-3 versions).

Android and Multi-Core Processor

Bell points the finger at chipset makers - "The way it's implemented right now, Android does not make as effective use of multiple cores as it could, and I think - frankly - some of this work could be done by the vendors who create the SoCs, but they just haven't bothered to do it. Right now the lack of software effort by some of the folks who have done their hardware implementation is a bigger disadvantage than anything else."

Pretty good valid arguments for the most part.
I mostly agree though, but I think android makes good use of up to 2 cores. Anything more than that it doesn't at all.

This was a serious problem on desktop Windows OS as well back when multi cores first starting coming out. I remember having to download patches for certain games and in other cases, having to set the CPU affinity to run certain games/apps with only one core so that it wouldn't freeze up. I am sure Android will move forward with multi-core support in the future.

Its a harsh but fair punishment imo. They need to sort that sh*t out as its totally unacceptable or they're gonna get a taste of the Cat o Nine Tails.

Android kernel is based on Linux. So this is suggesting the Linux kernel is not built to support multi-core either. Not true. There is a reason the SGS3 gets 5000+ in Quadrant, the the San Diego only gets 3000+. And the San Diego is running 200MHz faster.
Just look at the blue bar here. http://www.engadget.com/2012/05/31/orange-san-diego-benchmarks/ . My SGS3 got over 2.5K on just CPU alone.

What Intel said was true. Android is multicore aware but the os and apps aren't taking advantage of it. When this user disabled 2 cores on the HTC one x it made no difference at all in anything other than benchmarks.
http://forum.xda-developers.com/showpost.php?p=26094852&postcount=3

Disabling the CPU cores will do nothing to the GPU, hence still getting 60 FPS. And you say that like you expected to see a difference. Those games may not be particularly CPU intensive, thats why they continue to run fine. They will more than likely be GPU limited.
Android is not a difficult OS to run, thats why it can run on the G1, or AOKP can run smooth as silk on my i9000. If it can run smooth as silk on one 2yr old 1GHz chip, how COULD it go faster on a next-gen chip like in the SGS3 or HOX? In terms of just using the phone, ive not experienced any lag at all.
If youre buying a phone with dual/quad CPU cores, and only expecting to use it as a phone (i.e, not play demanding games/benchmark/mod/what ever else), of course you wont see any advantage, and you may feel cheated. And if you disable those extra cores, and still only use it as a phone, of course you wont notice any difference.
If a pocket calculator appears to calculate 1+1 instantly, and a HOX also calculates 1+1 instantly, Is the pocket calculator awesome, is the HOX not using all its cores, or is what it is being asked to do simply not taxing enough to use all the CPU power the HOX has got?

I've been hearing this for some time now and is one of the reasons I didn't care that we weren't getting the quad core version of the GS3

Okay folks... firstly linux kernel, which android is based on, is aware of multicore (its obvious) but most the applications are not aware, thats true!.. but is not the android which to blame neither the SoC makers. This is like the flame intel made that they wanted to say their single core can do faster to a dual core arm LOL, (maybe intel will make 1 core has 4 threads or 8 threads) <- imposibruuu for now dunno later
you will notice the core usage while playing HD video that require cpu to decode (better core decode fastly)... and im not sure single core intel does better to arm dual core.. ~haha~
but for average user the differences are not noticable.. if intel aiming for this market yes that make sense... but android user are above average user.. they will optimize its phone eventually IMO

What they have failed to disclose is which SoC they did their test on and their methodology. Not much reason to doubt what he's saying but you gotta remember that Intel only have a single core mobile SoC currently and are aiming to get a foothold in the mobile device ecosystem so part of this could be throwing salt on competing products as it's something that should be taken care of by Google optimising the CPU scheduling algorithms of their OS.

The problem is in the chip set. I currently attend SUNY Oswego and a professor of mine Doug Lea works on many concurrent structures. He is currently working on the ARM spec sheet that is used to make chips. The bench marks that he has done shows that no matter how lucky or unlucky you get, the time that it takes to do a concurrent process is about the same where on desktop chips there is a huge difference between best case and worse case. The blame falls on the people that make the chips for now. They need to change how it handles concurrent operations and then if android still cant use multi-core processors then it falls on the shoulders of google.
that is my two cents on the whole situation. Just finished concurrency with Doug and after many talks this is my current opinion.

Disabling the CPU cores will do nothing to the GPU, hence still getting 60 FPS. And you say that like you expected to see a difference. Those games may not be particularly CPU intensive, thats why they continue to run fine. They will more than likely be GPU limited.
Android is not a difficult OS to run, thats why it can run on the G1, or AOKP can run smooth as silk on my i9000. If it can run smooth as silk on one 2yr old 1GHz chip, how COULD it go faster on a next-gen chip like in the SGS3 or HOX? In terms of just using the phone, ive not experienced any lag at all.
If youre buying a phone with dual/quad CPU cores, and only expecting to use it as a phone (i.e, not play demanding games/benchmark/mod/what ever else), of course you wont see any advantage, and you may feel cheated. And if you disable those extra cores, and still only use it as a phone, of course you wont notice any difference.
If a pocket calculator appears to calculate 1+1 instantly, and a HOX also calculates 1+1 instantly, Is the pocket calculator awesome, is the HOX not using all its cores, or is what it is being asked to do simply not taxing enough to use all the CPU power the HOX has got?

That doesn't mean daily task doesn't need the cpu power. When I put my sgs 3 in power save mode which cut back the cpu to 800mHz, I feel the lag instantly when scrolling around and navigating the internet. So I can conclude that performance per core is still much more important than number of cores. There isn't any performance difference either with the dual core sensation xe running beside the single core sensational xl.

The hardware needs to be out for developers to have incentive to make use of it. It's not like Android was built from the ground up to utilize 4 cores. That said, once it hits enough hand it and software running in it will be made to utilize the new hardware.

[Q] safe gpu and cpu voltages!?

Hello i have been searching but cant find the max safe voltages for the CPU or GPU thanks if you can link me or help

Every device is different, there is no voltage that is perfect for every device.

I know that, thanks for responding. I mean the nvidia specific safe voltage chart so i don't fry my device when overclocking like i did before

That is called Stock behavior.
What, you think that Nvidia/Google/Asus sat around in a meeting and said to each other,
"Hey, look, we really could run this thing at 200% of our current maximums without any risks at all, but let's not do that because this tablet market isn't very competitive and nobody will care if our performance is crappy compared to other devices. Let's decide to operate it at only one-half or one-third of it's safe capabilities - for no apparent reason whatsoever - just so we can."

Just let everything as it is on default bro

Dude there is a "/official nividia voltage chart for tegra 3 somewhere all Tue devas talk about one." Thanks for answering. Yeah they could actually look at the new tegra 3 game console it is at 2.3 GHz and also the one in nexus 7 is under clocked to 1.3 to conserve battery life as it is vey stable to 1.5/1.6 ghZ

There is no default for the gpu on m kernel. Over clocking while theoredicly killing your prossesor faster actually can add life to our tablets becuase they will be able to run more recent things when tegra 3 becomes obsolete and we get better games and a newer os in a few major updates. I benchmark in 3dmark a good 3xs stock when in the 600mhz GPU range and 1.7 prossesor clock so i know this will help us run recent stiff. Just wanted to know is there is a nvidia specific """"chart"""" of some kind or manufacturer's guide to safe voltages and clock speed as some dev said" the voltages are high although within nvidia limits" do you know the limits is what I'm asking...

Not saying this is the case specifically for the N7, but there are many corporations out there who would do this type of thing (*cough* intel *cough*).

The game console nvidia shield has an tegra 4i which is far more powerful and can be clocked very high, theres no tegra 3 game console.
Safe OC goes up to 1.5 GHz, but look at one x+ still stable @1.7 ghz and 520 mhz gpu.

All semi houses sell their parts in different speed bins, and a price premium is demanded for the high performance bins. So the OEM gets to decide what the performance range will be - constrained by the price target of their design. The fact that a 2.3Ghz Tegra3 speed bin exists does not mean that all parts have that capability.
In any event the "voltage table" you are looking for is published in the stock kernel source code.
The N7, priced @ $200 never was a premium product. A damn fine value for the money, though IMO.
Hard to believe in the planned obsolescence hypothesis (in this case), as it appears that Google is selling the N7 at a loss. Usually planned obsolescence occurs hand-in-hand with a profit motive.

Back to the topic.... Could someone help me find the sourse code for tegra 3 so i know and others how to over volt to achieve certain clock speeDs
