How's TI OMAP4 performance on GNex?

Guys, I don't know if it's the right section, so I'll gladly ask to a moderator to move it, if I'm wrong.
To the point, I'm about to get a new GNex to me, and every single place where I read, I always hear good things about the phone. I wanted to ask how is the day-to-day performance, gaming performance and how it performs when compared to Tegra 2 or Qualcomm S3 or S4. I know Quadrant is not an indicative of the phone's real performance, so I want your help to figure out why Quadrant results are poor compared even to Tegra 2, and if I'll feel any hiccups or something like that...
Thanks for the help!

I haven't experienced any hiccups since the 4.1.1 update and gaming is definitely very smoothe.

Games are smooth, and the performance is good. Overall the OMAP is adequate for the purposes.

you get low quadrant scores on aosp/cm builds. Stock Google is also like aosp, thus lower scores.
If you really want to check, try antutu.

day-to-day performance:
Tegra 2 + Snapdragon S3: TI OMAP 4460 wipes the floor with those two.
Snapdragon S4: Best mobile "day-to-day" SOC to date, so you figure it out.

Well,
I came from an LG Optimus 2x (Tegra2 @ 1GHz, 512MB of RAM) and the change was HUGE!!!
Tegra 2 was a great graphics oriented SoC and with the Nexus I still get more performance with more pixels to render (1280x720 vs 800x480). I know that more RAM on the Nexus helps, but gaming is still great in the Nexus.
In many websites they still recommend the Galaxy Nexus from newer phones because of the value/price ratio. In fact, in Android Central, the Galaxy Nexus was still the best android phone as of July 2012 thanks to the buttery UI in Jelly Bean which makes it as fast as an S3 or a OneX. I only have a couple of weeks with the phone and I love it.
Cheers!

what you mean with that? OMAP is better or not? didn't understand it

when you wipe floor with something, that means that thing is rubbish.

so OMAP4 > S3, okay

Yes the omap is a superb chipset one of my favorites. Its more elegantly designed then some others out there. Dual channel memory is huge. Decodes 1080p video at the hardware level. Its good.

So, if GNex was a TouchWiz Samsung, for example, Quadrant scores would be higher? If that's true, that's a relief, because AnTuTu produces higher scores than Exynos, for instance. About JB 4.1.1, does it affect gaming performance in anyway?

Snapdragon S4 is the king of dual core.
However, OMAP 4460 is still quite the respectable processor.

LG Optimus S vs Lg Optimus G

I couldn't find my device so I found the closest to it.
My question is what is the difference?
I'm looking for a phone with a wider and taller body that is within my free to $100 price range.
I had cancer within the last two years and had my right eye removed, along with my upper pallet and right sinus.
I email an communication a lot via my phone and Nexus 10.
My left eye is poor vision so I find my self bring ring the phone to my face to text.
Any recommendations? My credit won't let me switch from Sprint unless I get a prepaid from T mobile or Boost.

Man that sounds awful. Glad you're okay now though. Anyway, these two phones are not even close despite the name. The G is quad core ARM A15 1.5GHz. S is 600MHz single core a8. We have 4x the ram, an hd screen, newer os, and the G is better in every way. The s was made to be low end and the g is high end and a couple years newer. If both are in your price range, pick the G.

Pretty much everything at the same time. It's 4.7" vs 3.2". It's a newer screen technology. The only "Advantage" the Optimus G has is it's 14g lighter. However, i prefer a phone a bit heavier so the Optimus G is almost perfect for me.

The SoC in the Optimus G is a Qualcomm Snapdragon S4 Pro (with 4x Krait CPUs and Adreno 320 GPU). The Krait CPU is better than an ARM Cortex-A9 but not quite as fast as a Cortex-A15. Better power efficiency, though, as each individual core can be run at different frequencies, and unused cores can be powered off completely (current A15-based SoCs run every core at the same frequency).
Qualcomm doesn't use ARM's CPU designs, they build their own CPUs compatible with the ARM architecture.
Think of it like ARM=Intel and Qualcomm=AMD, to simplify things.

True, I oversimplified it, but it's closer to the a15 than a9. The A15 has a larger l2 cache than we do though.

[Q] Nexus 7 CPU GPU vs Tegra 4

Hey Guys,
i want to buy a new Tablet soon. But I cant choose which device I should buy.
I heard the new Nexus 7 has a Snapdragon 600 not S4 Pro, just underglocked.
But is the new Nexus 7 faster than the Nvidia Shield ?
Thank you

Wait for custom kernels to come out to see how much we can overclock the new Nexus 7.

Okay thanks for the Answer but what do you think could be faster? When Shield and Nexus 7 would be Overglocked which one would have more Performance?

the Shield for sure. the S4 Pro is a last gen processor. the T4 is still pretty new.
however, there are things to consider.
the New N7 is a tablet first, gaming "rig" second. its vice versa for the Shield.
the N7 is more portable
the N7 has a MUCH nicer screen
the Shield should only be bought if you plan on JUST playing games on it...something like a PS vita/Nintendo DS replacement. if you plan on using it for videos, surfing, other apps, i would stick with the N7.
my new N7 plays games beautifully....and honestly, I'm not sure i could tell the difference between it, and a T4 powered device. But I'm not one to get too cought up in the Frame Rate debate. the new one looks fantastic compared to my old N7, which looked fantastic compared to my galaxy nexu.

No, the teardown reveals it is a s4 pro, I have a nexus 4, the s4 pro works best at 1.7ghz, for me, overclocking to 1.8 or higher actually makes the chip slower. The tegra 4 destroys the s4 pro, just because it is newer, just like the s800 desteroys the pro/s600. I have yet to get this tablet, but I suspect it is a lot faster than the tegra 3 of the original nexus 7

Something like that. Its called one but its not one if that makes sense. Seems Qualcomm doesn't want to give the 600 name for anything under 1.7 GHz.
The naming scheme Qualcomm is using is nuts. But it is really essentially a 1.5 GHz snapdragon 600.

The iFixit teardown of the Galaxy S4 shows a chip named APQ8064, even if it's a Snapdragon 600.
Probably, it's just a new Snapdragon 600 version, made to run at 1.5 GHz.

Tab pro or tab s

Hi. I have purchased 8.4" tab pro. Love it. It has good natural screen and is fast. But then I saw online the tab s. Is the screen worth the extra money and is the battery life much better? I am also concerned of the small bezels. Where should I hold it without touching the screen

In my opinion (which I'm quite fond of) the Tab S is worth the extra money.
If I already had a Tab Pro 8.4 that would be hard to say.
The bezels are slightly (mm's) slimmer on the Tab S from Tab Pro. If you were fine with the Tab Pro you shouldn't be a lot worse off with the Tab S.

I just returned my Tab Pro and picked up the Tab S. I recommend the 10.5 model just because you can read websites in portrait easier.
I was worried the amoled screen would be too much but it's great and I love the blacker text.

So did I. Went from 8.4 pro to the 10.5 S. So far I am very happy that I did.

The Tab Pro 8.4" is a quadcore, whereas the Tab S 8.4 is a octacore. So Tab S in this case would be far superior, plus the ultra power saving mode, finger print lock, and Super AMOLED screen is way better too on the "S" series for the 8.4" Tab comparisons.

Debatable which processor is faster. Really depends on what you're doing with it. I had a chance to see them both side by side and the SAMOLED screen on the Tab S looked better to my eye, but again that's subjective. IMHO, it comes down to price. They were running the Tab Pro 8.4 for $249 last week. At that price, the Tab S just isn't worth it. That said, I walked out today with a Tab S that was a return from a customer who got the wrong color. Box was unopened, but the guy gave me a decent discount because there was a big sticker that had been ripped off the side of it. Box looked pretty rough, but the contents were untouched.

It's not superior I wish they'd put the snap 801 instead of the exynos chip as only four cores can work at a time. Unless they can find a way to unlock. Plus it may take longer to root or get custom roms. I had the tab pro and a root was out in a couple of days.

I read the anandtech review it sounds there like it's only 4 at a time though the wording is confusing...

The WiFi only variants of the Galaxy Tab S all feature Samsung’s own Exynos 5 Octa (5420). Internally we’re dealing with four ARM Cortex A15s and four ARM Cortex A7s in a big.LITTLE configuration, with a maximum of four cores of the same type being active at any given moment. The Cortex A7 cluster can run at up to 1.3GHz while the Cortex A15 cluster maxes out at 1.9GHz.

it won't be the first time anandtech made a major error. I've caught a few gaffes over the years. Since then, I don't trust their reviews. I treat it like going to a doctor. You get a diagnosis but always go to several other physicians for a more informed opinion.

I was under the assumption that the Exynos 5420 didn't have HMP enabled. Samsung released a vague statement in the past saying that they could update the kernel on devices running the 5420 so that HMP works, but I'm not sure if anything came from it. Of course, I could be totally wrong and Samsung got HMP working on these devices.
According to an Anandtech article (I know, sorry) on the newer 5422 processor back in February:
"The 5422 supports HMP (Heterogeneous Multi-Processing), and Samsung LSI tells us that unlike the 5420 we may actually see this one used with HMP enabled. HMP refers to the ability for the OS to use and schedule threads on all 8 cores at the same time, putting those threads with low performance requirements on the little cores and high performance threads on the big cores."

Any links to back that up? Everything I read says no 5420 has HMP turned on and that the Tab S only uses one set or the other depending on performance needs, never both together.

Hmm, you're right. I really should've checked more sources. One minute Google research doesn't get you really far. In that same article Anandtech's chart lists the max number of active cores for the 5420 as: 4 (?) .

Do what I did. Speak to technical support at Samsung.
I'll go one step further. What we do know is that the 5420 in the Tab S is scoring 35,000+ in Antutu...
It seems that our Note 2014 versions usually score about 32,000+, So that lead me to suspect that the newer Galaxy Tab S 5420 was HMP enabled due to the higher Antutu scores.*
And again, had confirmed when I spoke with Samsung directly.

My note pro 8.4 with snapdragon 800 scores 35000 as well, I wouldn't call that proof on HMP. When you read the specs for the 5422 they state first chipset with HMP. Color me dubious that it's been turned on for the 5420. I hope I'm wrong

You're comparing apples to oranges. We have an AMOLED screen using the Exynos Octa 5. The Snapdragon on an inferiorly smaller screen (without AMOLED) will naturally get better CPU/GPU scores on Antutu

Hi all,
so me and a friend got our t-mobile Samsung Note 3 within a week of each-other at the same T-mobile store about 8 months ago, so just the other day we were siting around and ran Antunto to see how our phones would ring up, we both have stock phones, he ran 36??? on Antutu and I got 42742, so we started to look at our specs and he has an Qualcomm Snapdragon MSM8974 and I had a Qualcomm Snapdragon MSM8974AB even our dpi are different he has I think 340 and I have 480 dpi...
Any info on this would be appreciated.
Thanks

Don't think im complaining, Sh*&t , I love my phone its fast and vibrant, was just wondering if any one had this happen to them...I feel bad is for my friend who thinks his phone sucks...
but even the screen ppi of 480 is above norm....

480 is stock DPI. I use app settings to maximize real estate on my screen, usually end up using 400/420 DPI myself so it doesn't look like something a 3yr old would use. As for the antutu, installed apps, and apps running in the background, and time since last reboot all contribute to your overall score. Even having a case that restricts heat dissipation will cause you to hit the thermal throttle easier as well.
BTW, same model number with the ab and DPI on my device, 44053 over here.
