Motorola Xoom has a Tegra 2 chip and it handles gaming just fine at a higher resolution, SGX540 @ 200 is generally faster than Tegra 2 isn't it? So wouldn't SGX540 be fine?
[Samsung Galaxy Nexus] tydem:
Exactly. Tegra 2 is much slower than the OMAP in both CPU and GPU performance if the SGX540 is clocked at 384 Mhz. Therefore the Galaxy Nexus should be able to run any game that works on Tegra 2 (though it might need Chainfire). This includes GTA 3 by the way. However Mali is still much faster, especially when overclocked to 400 Mhz. If only there were games or emulators (Dreamcast for example) to take advantage of that...
[Samsung Galaxy Nexus] Dragooon123:
Mali is much better, yes, but I am not trying to go into all the hypothetical scenarios and say had it been this or that it would've been much better. I'm looking for actually getting this phone when it comes out and I just want to fully justify it being enough in every department of my needs.

I found a benchmark :

Now the LG Optimus 3D runs a OMAP 4430 @ 1Ghz which's GPU is clocked much less than that of a OMAP 4460 present in Galaxy Nexus and it still performs better than LG Optimus 2X running a Tegra 2 chip at the same resolution. I've been looking at YouTube and other site on Motorolla Xoom's gaming and it seems to be running them just fine at 30+fps, I don't see why a SGN would fail to perform.
[Samsung Galaxy Nexus] Jebus99:
I think the worry is that with the SGN's 720p resolution and the need to push more pixels than any other phone, that the SGX540 might not be able to keep up. That being said, Google knows how critical android fans are so I think they probably only picked it after ensuring it can so i'm not too worried
[Samsung Galaxy Nexus] disclaimernotice:
Fir me, the only problem is the lack of sd slot. As for the GPU, it doesn't actually matter. The GPU would be used to its maxed only when playing hd games, but hd game makers like Gameloft aren't gonna make games that can be supported by only a narrow range of GPUs, because then their market would be too small. Hence, there will be no games that will require GPUs more advanced than that of the Galaxy Nexus anytime soon.
[Samsung Galaxy Nexus] Dragooon123:
What I said was that Motorola Xoom has a higher resolution than Galaxy Nexus and a weaker GPU and it still manages to do just fine.
[Samsung Galaxy Nexus] pukemon:
I dont think the xoom is higher. Isnt it 1024x768? And i like how everybody keeps saying the mali is more powerful than this or that gpu, and then go on to make comparisons of mail running 800x480 to 960x540 or higher, but the numbers at 800x480 are better. I want to see the mali bow down at a higher resolution. Methinks the tegra2 and mali are a lot more comparable than its made out to be. And im really interested to see how much muscle this oc'ed sgx540 has or if it will crumble when pushed.

I voided my warranty and your mum.
[Samsung Galaxy Nexus] Dragooon123:
Xoom is 1280 x 800, that's 11.1% more pixels than Galaxy Nexus(If I remember my maths right)
[Samsung Galaxy Nexus] Jebus99:
But also note that the Tablet Tegra 2 is a different model from the Handset Tegra 2. I know at least the GPU is clocked faster. Its similar to how the A5 in the IP4S is different from the Ipad2.
[Samsung Galaxy Nexus] Dragooon123:
The gpu is clocked 33 mhz faster according to wikipedia.
[Samsung Galaxy Nexus] jaykresge:
Sort of, but not the same. When you place a CPU and a GPU on an SOC, they are tied together by a multiplier. This is similar to how you have to overclock your FSB on your motherboard in order to effectively overclock your CPU (or, just change the multiplier). The reason that the GPU in the iPhone 4s is slower than the one in the iPad 2 is because the entire SOC is underclocked.

When you compare the Atrix to the Xoom, they're not even using the same SOC. The Atrix (and most smartphones) use the Tegra 2 AP20, while the Tablet version is the T20. These have different multipliers. So, they're not the exact same SOC as you would see in the iPhone 4s and the iPad 2. Anyway, there's just a bit of background on the differences.
[Samsung Galaxy Nexus] Jasonhunterx:
Y is the gpu such a big deal i have galaxy s with the sgx540 i can run all the games easy an thats with a single core an galaxy nexus is going to have dual core an gonna be upclocked an more ram so i see no problem :-/
[Samsung Galaxy Nexus] jaykresge:
A lot of people don't understand that the GPU used in today's SOCs is actually far superior to the one used in the original Galaxy S or Nexus S. Part of the problem is that PowerVR's naming conventions are horrible. SGX540 is the name of the chip, not the product. On the PC side, Nvidia would sell the same chip at different clock speeds with different product names to avoid this confusion.

The SGX540 used in the Droid RAZR and Galaxy Nexus is 2.5-3x the speed of the one used in your phone. It's no slouch. It also beats the Mali400 in some key areas.

However, the Mali has some advantages of its own. For one, it has an obscene fill-rate, giving it better response on high resolution displays. For a WVGA or qHD display, I'd take the SGX540, hands down. For a 720p display, Mali wins in most cases. I'd still take the SGX540 though, as I'm a gamer, and I suspect that the more balanced SGX540 will be more future proof. That last line is speculative on my part only.
[Samsung Galaxy Nexus] Dragooon123:
The difference between Tegra 250 AP20H(Used in mobile devices) and Tegra 250 T20(Used in tablet devices) is that T20 has 333Mhz GPU frequency vs 300Mhz GPU frequency of AP20H, their CPU frequency is same. That's more or less a 11% performance increase for a resolution increase of 100-200%(Since Mhz increase in the same chip would more or less translate linearly).

Galaxy S/Nexux S runs a hummingbird SoC with SGX540 running @ 200Mhz, Droid Razr/3/Bionic has OMAP 4430 running SGX540 @ 304Mhz whereas the Galaxy Nexus has a OMAP 4460 running SGX540 @ 384Mhz. Apart from this the CPU clock speed of 4460 is rated to be between 1.2GHz to 1.5GHz(So, once rooted it should easily achieve 1.5GHz atleast), and the 4430 is to be between 1 - 1.2Ghz.

I found a decent OpenGL benchmark, this is a synthetic benchmark and doesn't mean a lot but it still gives an idea(Ignore the humiliation caused by A5)

Now I am not sure what drugs Infuse 4G is on, since it is running a slightly overclocked hummingbird processor, yet it quite easily beats a much more overclocked Omap 4430. Probably software optimisations, but even running a much older hummingbird SoC Infuse 4G manages to be kind of close to the Mali in Galaxy S2. Galaxy Nexus would be(should be) quite faster than Infuse 4G, not only since it's core clock speed is faster and it has a better CPU, the software is also designed around OMAP's hardware and should be very optimised and suited. So on a one to one basis it should hold quite well against its own against Mali. Not only this, the benchmark is running at 720p and the SGX540 is managing to pull of 21-25FPS, which is respectable considering games generally run much higher than this. Plus it is also beating Galaxy Tab 10.1 running a Tegra 2, and it is quite a good gaming device.

Conclusion : SGX540 should be fine.
[Samsung Galaxy Nexus] jaykresge:
My understanding is that the GPU frequencey is tied to the CPU frequencies in these SOCs. So, at 1.5ghz, the OMAP4's GPU is 384mhz. However, at 1.2ghz, it is likely slower.

In the Tegra 2 example, they were technically two different SOCs. Due to this, it is highly likely that the RAZR's GPU is slightly faster than the Bionic's, and the GN's GPU isn't quite 384mhz.
[Samsung Galaxy Nexus] tom369:
I was looking forward to this phone, now I'm a little bit disappointed. Yes I will complain about "only" 5 Mp camera - not because it's 5 Mp only but because there are other top smartphones on the market (4S, SGS II, ...) that use a 8 Mp sensor and can produce high quality images. So it is totally possible today to have a 8Mp sensor in a phone and get a good photo out of it and Nexus lacks it. Another thing: I don't like Pentile-like tricks to achieve HD resolution and this is main showstopper for me. It looks like Samsung was unable to manufacture real HD display (non Pentile) for a phone as for today. So I'm skipping it and waiting for SGS III or other iteration.
[Samsung Galaxy Nexus] Dragooon123:
To be honest I can't deny or confirm that the clock speed of GPU might be lower, every instance of GPU's clockspeed I can find with respect to Bionic mentions it at 304Mhz but I can't find any definitive proof from Motorola. And I doubt that their clockspeed is related, since overclocking my Galaxy S doesn't result in better GPU performance, but I can be very wrong as I'm not sure.

As far as Tegra 2 goes, they are more like 2 branches of same SoC, both are more or less the same but with speed difference of 33Mhz in GPU ( http://www.notebookcheck.net/NVIDIA-Tegra-250-Notebook-Processor.54654.0.html ).
[Samsung Galaxy Nexus] KWKSLVR:
But AGAIN, what are people going to do with an 8MP photo taken from a cell phone camera? I mean, are people pulling them off their phone and uploading them to Walmart.com, blowing them up to 8x10 then picking them up an hour later? I rarely take a picture at 5MP on my SGS. Normally I keep it around 2.5MP. Why? Because my pictures are going to be:

1) Emailed via my Android and viewed by friends on their Android's

2) Automatically uploaded to Google+ (and resized in that process anyway)

3) Uploaded to Facebook (an resized or flat out rejected if they're too big)

There is ZERO quality difference between 2.5MP and 8MP with a picture taken with the same camera/phone. The only difference is the size. So again, how many people are PRINTING photo's taken with their phones? I hate to keep harping on this in every thread, but I'm really trying to figure out why people care about 8MP over 5MP other than the general notion that More Must Equal Better.

All more MP's means is a larger file size and lord knows there's enough whining over no microSD. ;)
[Samsung Galaxy Nexus] SwiftLegend:
Physics teacher last eye told us the each eye sees a maximum of 28 fps. Thomas Edison said that anything below 46 fps will strain the eye..(28+28=46). Read a review on a camera that records in 32 fps, and they claimed that was the optimal fps, since it feels more realistic.

This is just based on memory, so I could be wrong..
[Samsung Galaxy Nexus] Dragooon123:
Human Eye can notice the difference between 30fps and 60fps, I know I can. Anything beyond 30fps is smooth, anything beyond 60fps is useless.
[Samsung Galaxy Nexus] pukemon:
Lmao. I know your math is wrong. Try again.

30fps is the minimum speed for smooth motion. 60 is ideal, but pretty much useless. But it can gauge power of gpu somewhat. If you throw the same tests at different gpus and they all average about 42 fps but so and so gpu can blast through said test at avg of 77 fps, x gpu can be said to be almost twice as powerful as the others. But you cant make a definitive conclusion on that unless the test thoroughly tests the gpu across all features without any optimizations to look better in one test but suck balls in another.

I voided my warranty and your mum.
[Samsung Galaxy Nexus] jaykresge:
I think we'll both just have to wait and see, because I can't find a link one way or the other. However, I will have to stop posting my position as fact, because until I can back it up, it is clearly not fact. I do appreciate the info that you did provide!

Did you know that you ONLY need a 2.1MP camera for 1080p, or a 1.0MP camera for 720p? Don't fall for the megapixel wars. The larger the MP count, the larger the aperture that you need in order to maintain clarity. I do believe that the iPhone 4s uses a larger aperture than the iPhone 4. However, that's real estate, and simply may not have mixed with Google/Samsung's desire for the phone that they were making. I don't print posters, so 2+MP is fine for me.

As to the person(s) talking about how much the eye can perceive in terms of framerate, here's something for you;

Your eye takes snapshots as fast as your brain can refresh. This means that you detect motion via a framerate unique to yourself. The most fluid motion you will ever see is a video running at the exact framerate and timing as your own eyes and brain. This can't be done. So instead, we keep upping the framerate. Even if your eyes/brain only run at 24fps, for example, you will still see more fluid animation going from 30fps, to 60fps, even to 120fps. This is because your eyes are not in sync with the material, and the 24 frames in a second that yours eyes pick out will differ depending on the framerate of the video. The more possible frames of motion in the video, the smoother it will look to you.
[Samsung Galaxy Nexus] ArmedandDangerous:
More pixels on the same sensor size = less light per pixel = higher noise in low light. That is why the Canon 1D X is "only" 18 MP on a full frame sensor.

I once heard that they chose Texas Instruments among others because "when they (Texas Instruments) say it's done by tuesday, it's done by tuesday. And it's done well."
[Samsung Galaxy Nexus] no1msd:
I don't care about the camera, or the SD card.. but it has the same GPU as my 1.5 years old SGS? :\ Bummer.
[Samsung Galaxy Nexus] peachpuff:
The sgs had the fastest gpu in its time, the gn has the same one clocked at twice the mhz... whats the problem? Are there even any games out there that the original galaxy can't play? Or do you all care about are synthetic benchmarks?
[Samsung Galaxy Nexus] :
The original SGS had a lover resoliution. The new Galaxy Nexus has twice the resoliution and that mean it needs to be able to deliver twice the power.
[Samsung Galaxy Nexus] SwiftLegend:
Yeaahhhhh just realized that :) Probably why I have a B in Geo now :)
[Samsung Galaxy Nexus] pukemon:
I snorted when you tried adding 28+28. Twas pretty funny.

I voided my warranty and your mum.
[Samsung Galaxy Nexus] leerobson99:
Amen!!

When I got to this post I could not read anymore of this thread. This guy is right.

I have faith in Google to make this phone awesome. So should you!

Sent from my Nexus S
[Samsung Galaxy Nexus] jaykresge:
No bummer, as they're not the exact same GPU. Well, unless you consider a V6 Mustang and a V8 Mustang to be the "same car." :)

The overclocking makes a huge difference. The PowerVR SGX in the Galaxy S was clocked at 200mhz. The one in the Galaxy Nexus is clocked up to 384mhz.

So, if you take that V6 and "race" it at 50mph, and I take the V8 Mustang and run it at 100mph, think we'll tie? :)

Here's the problem with that. Most video cards run into a limitation first with either; memory, geometry, or fill-rate. If they hit a wall in one area, you can continue to raise the other without further affecting performance. To say that the GPU in the Galaxy Nexus needs to be twice as powerful would be to imply that it was at it's fill-rate limit on a WVGA screen. It wasn't. Now, fill-rate is an issue at 720p, but not the issue you're assuming. All benchmarks so far look favorable. We'll see what the final device looks like.

People are panicking over this GPU for the wrong reasons. This thing is NEARLY 2x faster than the one used last year. The reason I'm upset is that Apple got the SGX543MP2, and no Android OEM even thought to use that. I can understand Qualcomm and nVidia using their in-house parts, but there's no excuse for TI and Samsung.

EDIT: FYI, fill-rate requirement to run a 720p screen at 24-bit color with full transparency at 60frames per second is 221 megapixels/second. The SGX540's advertised fill-rate at 200mhz is 1 gigapixel/second, or 5 times the requirement for 60fps operation on a 720p screen. So, at nearly 400mhz, we're talking nearly 10-times what's needed for the Galaxy Nexus. I think we're good :)
[Samsung Galaxy Nexus] pukemon:
also throw in double data rate ram which effectively doubles bandwidth aaaaaand 1gb of ram rather than 512mb. i would assume the gpu gets 128 megs of that dedicated and probably up to 256 megs for games or hdmi mirroring.

also, ti and samsung didnt spec this phone. it is google's 3rd baby.
[Samsung Galaxy Nexus] jaykresge:
Galaxy S (first-gen) used dedicated RAM for the GPU. Every other Android phone I'm aware of uses unified RAM (like the XBox 360). So, GPU gets RAM allocated as needed.

Google/Samsung chose the SOC. However, the SOC manufacturer (TI for OMAP, Samsung for Exynos) chooses the components of the SOC. Google can't just say "Ok, I want an A9 CPU, and a PowerVR SGX543MP2 GPU." They have to use existing parts, and Apple isn't giving them the A5. So, it was down to Exynos or OMAP4, and they chose the latter.
[Samsung Galaxy Nexus] pukemon:
are you sure about that? i thought all android phones use a unified memory architecture. i haven't read anything about android gpu's having discrete ram though that would be really badass and help performance even more. and i know that all these parts aren't basically a la carte. a lot more goes into it than ordering off a menu, but it would've been nice to get a 543mp2 or 544. i think everybody would feel a little more comfortable seeing as we haven't got any concrete evidence that the 540 will be able to handle just about any game, just not at 720p. probably 540p is the best we'll get.
[Samsung Galaxy Nexus] jaykresge:
Doesn't this contradict your last post where you thought that the GPU had dedicated RAM? Regardless, the Samsung Galaxy S is the only phone I'm aware of with discrete RAM for the GPU (384MB for system, 128MB for GPU). Every other Android phone that I'm aware of has unified memory.

Anyway, the comment of yours that confused me was:
[Samsung Galaxy Nexus] pukemon:
yes, dedicated as in allocated from the 1gb system ram. sorry for the confusion. i didn't mean discrete, which is onboard ram for the gpu.
[Samsung Galaxy Nexus] jaykresge:
Ahh, ok. I don't know how the OS works, in that regard. Windows, for example, allows you to allocate system memory to the GPU, and allows you to set a limit. On the 360, the system balances the memory between the system and GPU as needed. Android may work like one or the other, or in a different way. All I know for a fact is that almost all Android devices use unified memory, with the OG Galaxy S being the only exception that I'm aware of.
[Samsung Galaxy Nexus] Maroon Mushroom:
The SGS had a much lower clock on the GPU.

This GPU is clocked much higher and may have room for OC
[Samsung Galaxy Nexus] Sjael:
Here's a lovely anecdote: I use an Eyefinity (three-monitor) setup on my gaming rig. It's a general rule of thumb that (compared to a single 1080p monitor) adding an additional 1080p monitor will reduce your performance by about 30%. A third 1080p monitor will reduce your performance to about 50% that of a single-screen setup.

Now consider, the Nexus Prime has about 2.4 times the number of pixels as the Nexus S. If the same formula as a desktop GPU holds true for mobiles, we could expect about a 40% loss in 3D performance. Now the GPU has been clocked up about 92%. It's throughput is now approaching double that of the Galaxy S, when it needed only make up a 40% defecit. Of course if you consider diminishing returns from clockspeed scaling, the SGX540@384MHz should perform at 720p about as well as it did at 200MHz and 480p. /shrug

The usual disclaimer: this was all conjecture on my part. :)

I imagine you would find that everything on the chip would share a base frequency (the FSB you mentioned) that the various cores have individual multipliers for. In that case, it would be a relatively simple matter to keep that SGX540 running at 384MHz, but bring the AP Cores down to 1.2GHz for stability/battery life/whatever.

Of course I have no clue how they actually derive their clocks, but it makes a lot more sense to have many processors multiplying one base frequency than to have many base frequencies to one multiplier.
[Samsung Galaxy Nexus] kingcedz:
Pre-ordered mine yesterday, but now seriously considering cancel the order.

The more I think over the details, the more underwhelmed I feel about the hardware. Nexus heritage is suppose to be the flagship device that set the standard for the next generation of Androids, and none of the hardware features on Galaxy Nexus has managed to pushed the envelope.

OK, the processor is new. But to be fair, in a market where a Chinese Startup firm (XIAOMI) is already able to manufacture with MSM8260 Snapdragon Dual Core @ 1.5Ghz, the OMAP 4460 1.2Ghz is hardly a breakthrough.

The Camera is ok (5MP is more than enough) and the instant shutter is great. But I m not sure if it's an edge over for example HTC EVO 3D that has a very fast shutter speed AND a delegated camera shutter button.

The screen is massive, but as many articles recently has pointed out, there is a material difference between Super AMOLED+ and Supler AMOLED. again, Galaxy Nexus is not really cutting edge when there are already a number of phones with Super AMOLED+. Bear in mind, Super AMOLED Plus is Samsung's own technology. That's not really what I would call a flagship device if they are not even willing to put their own best technology in this puppy.

I personally think 16GB is enough, but I can see the points many making regarding not having the flexibility of SD card. Afterall, its not really in line with the "Open" concept of Android, and I dont really see the reason of not having the option.

The overall quality as many has pointed out is very plasticy. It might just be a personal preference, some people like plastic, some likes metal. But you cant deny the fact that the plastic build is A LOT cheaper than metallic exoskeleton structure. HTC aside, Motorola is using Kevlar (which looks and feels like carbon fibre) in the RAZR, and both of their latest phone cost far less than Galaxy Nexus. honestly, the price doesn't make sense.

And one side point: the way Google is selling the Galaxy Nexus is SOOOOO MESSY! Nexus One was sold directly on day one, Nexus S didnt, but the information regarding where and when and how to buy the phone was available on the spot. This time, not a clue who s really selling it, when is the launch day, What's the official sales price. I reckon most guys never even heard of Clove or Handtec before, I would hardly reference their price as official launch price.

I've been with Andriod since the original G1 and have bought the N1 and NS on launch. To be honest, I blame it all on Samsung. The Nexus One was more Google than it was HTC, pushing the envelopes in terms of hardware standards and software in every direction. Nexus S and Galaxy Nexus feels like it had nothing to do with Google at all, just some phone to launch the new version of androids with.

I can only hope when Google completes the Motorola merger, someone who actually knows how to make phones can really take care of the Nexus brand.
[Samsung Galaxy Nexus] Dragooon123:
And that SGS can still pull off any game just fine, only to be held back by the RAM and sometimes the processor. We got to wait for benchmarks but I think we'll be fine.
