Performance Concerns - Galaxy Tab 10.1 General

Why is everyone saying this tablet has lower performance than the likes of other Tegra 2 tablets? Shouldn't it be pretty much the same? For example, Engadget said it only got a 1500 in quadrant and that it wasn't too nice with games whereas other tablets did just fine. I'm concerned about this because my primary use for a tablet would be gaming and web browsing.

Regarding the Quadrant score.
The Transformer shipped with 3.0.1 and had a Quadrant score of around 2000. After updating to 3.1 the score dropped to 1500.
I'm hearing the same thing with the Galaxy Tab now, with 3.0.1 it had scores of around 2000 and post 3.1 they dropped to 1500.
Yet at the same time Transformer owners felt that despite the Quadrant score drop, the tablet did feel slightly more responsive and quicker. Not sure what is causing the Quadrant scores to drop, but it might be an example of why we shouldn't put too much stock in just benchmarks.
I haven't heard anything negative about the Galaxy Tab 10.1 and gaming performance.
Sadly the Android 3.1 update did make the stock browser keyboard really laggy with the Transformer. Don't know how much this has affected the browser with the Galaxy Tab, though I created a thread about it and it doesn't sounds like it's as big of an issue as it has been for the Transformer.

I got around 1500 as well. Its funny because my Droid x is getting almost 1700. The tablet feels much snappier then the X. I wouldn't worry about the numbers. Maybe Quadrant needs an update.

Just like computer video cards... Don't put a lot of faith into synthetic benchmarks... It's all about the real world frame rates and speed...
Reminds me of an ancient editorial at HardOCP as to why synthetic benchmarks are generally bad.

Quadrant benchmark for Android on HD2 compared to SGS (What's in a score)

Look at this (from 1:44 on):
It's a quadrant benchmark run on a android port on the HD2. Graphics are really bad, but in the end it has approximately the same score as the benchmarking score of the Galaxy with the original firmware. I mean what is in a score? If I look at the beginning of the movie, the UI is very slow and not as responsive as the Galaxy
(BTW i got 55.7 FPS with the neocore benchmark on JM2)
This is not to say that I don't have deep respect for what the HD2-android development team is doing. Really amazing job. I just can't wait to get my HD2 back from repair.

Quadrant scores have been criticized for their non-descript breakdowns, at least on their free suite. Also, the fact that they chose the weighting of the scores, so should they chose 2D is equal to 3D weight, I don't know their formula (and for all I know, they give equal weighting to all or they give equal weighting to all test where the CPU has 12 tests and the 3D graphics has 4), but the fact that we, as users don't have access to their formula on their website is a bit unnerving.
Add to that the fact that many reviews and videos rely on it so heavily leaves users a bit misinformed. In reality, and thorough review should definitely run a custom test suite to give individual scores to:
CPU
Memory
I/O
2D graphics
3D graphics
That way users can compare what's important to them. The Galaxy S suffers from terrible I/O and the hacks that have given the fixes typically boost Galaxy scores to nearly double their rates, and it's majorly attributed to improving a bunk I/O score.
Totally agree. In addition, it would be really nice to know which benchmarked factors are responsible for which functions. For example it is really interesting to see how the hd2 performs before the user is running the tests. When the user is scrolling through the setting menu there is a very noticible lag. Given the fact that the total score is nearly the same as the scrore for the SGS, and thar the graphic score of the hd2 is bad in comparisson to the SGS, I would conclude that graphic performance is very important for the way the ui responds.

From what I can tell, the HD2 got a decent score 'cos it was running Froyo. When we get bumped up to an official froyo build with JIT fully optimized, We should be top of the pile.
don't forget, android isn't working 100% on the HD2.
I personally think it's pointless comparing to a not complete port.

Even then though, it's possible to write a benchmark which wins constantly for any phone.
In regards to "terrible I/O", that might even be due to a bug in the FAT32 drivers. Yes you can benchmark it, but it wont mean much. The best way is to actually TEST the applications you need, rather than select a phone based on benchmarks. However, you are possibly best off looking at the component specs, because they ignore software bugs.

But the topic is about "what's in a score". Maybe one can generally say that is pointless to compare devices this way. I think that such benchmark scores are only (a bit) relevant at the two poles of the benchmark score spectrum. Everything in between can be neglected due to the uninformed way sub-scores are evaluated.
You got 55.7 FPS on Neocore as the sgs has vertical sync enabled, the refresh rate on the sgs'es screen is 56 fps and thus you can only go up to 56 fps as the v-sync is on. This proves that the sgs is indeed a much more powerful device that is actually being held back. If you can disable the v-sync then you can get a higher fps score

I just read in a post that the Galaxy S gets a 0 on the 2D score:
"JIT isn't fully enabled in the current froyo versions, and quadrant, frankly, is bull**** (for exmple, 2d acceleration gets the same weight in the final result as 3D. Due to the fact that the SGS doesn't have a dedicated 2D accelerator, quadrant doesn't try to use the cpu- it just gives a round zero in that part)"
I can't confirm this, but that definitely seems like a terrible set-up, seeing as how I'm pretty sure I have games run in 2D, so to say that it can't do it just seems wrong regardless of if the SGS has a dedicated 2D accelerator or not (so if you aren't testing the way it performs in real-world, why are you testing?)

It isn't really being held back - the screen can't display more than 56 fps as you say, and it wouldn't really be visible even if it could. Disabling v-sync isn't really that important, we need a benchmark that can actually use the advanced features in the SGS GPU (Neocore just pushes a fairly small amount of polygons with no real extras.) Using current 3D benchmarks to benchmark the SGS is like using quake 1 to benchmark the brand new ATI/nVidia cards.
The benchmark is what is at fault here, not the device

I don't want to speak for the other poster, and I agree with your premise, however, it isn't actually solving the issue at hand. Better FPS wouldn't be noticed, however, it would give a better score and, more importantly, indicate it's potential. So, getting 56FPS isn't doing the phone any justice within the score, which is what reviews are using, giving it an artificially low score, and putting it more in line with units that can't compete on higher end games. So, when a site like anand pushes 150FPS on a game, I know that means that their rig is entirely too powerful for the game in question, but it still means something when you compare it to the lower end graphics card that only gets 90...then when they run Crisis you see these results play out more with differences that we can notice with the eye.
I think the HD2 gets that score because, as I can see in the video, the CPU tests run faster compared to my SGS, probably because of Froyo, and I know, from the time I had the Diamond and the HD2, that the internal memory and RAM are very fast. Sadly SGS has a slow internal memory, atleast when used by the phone`s software, when copying from PC is faster than my class 6 microSD. Luckily, we have mimocan`s fix. Hope this will be fixed in future FW`s.
NexusHD2 with-FRG83D V1.7 with hastarin r8.5.1 On my HD2 got 1920 in quadrant,31.5 on neocore, and 37 on linmark.
The lag might be because you are using launcher pro, I use launcher pro and sometimes it makes the the lock lag on my phone but it doesn't happen when I use the default lock also if you have alot of Widgets on your screen it will cause lag also

same galaxy s scores 6000+ in quadrant with custem roms
The HD 2 is a better fit for quadrent then the sgs as quadrent was made for the snapdragon processor which the hd2 has and the sgs does not. Comparing apples to orenges in an apple juice contest doesn't really prove much. Use real life feel. If you care about the scores a rom can be made to get you over 3000 quad score but is laggy as hell. Don't believe me? Look at my sig
interesting... I was using quadrant to see how a stock xxjvo and gingerreal compared. Surely that would indicate a real speed difference and not just be some kind of "hack" ?

That's right.
HD2 uses two android OS :
- Cyanogenmod, that is faster than our samsung os..
- Nexus one's port to HD2, greatly optimized by google...
It's really fast. I upgraded my father's HD2 last month, replacing windows in the NAND with CM7. It really makes a big change, the phone is like brand new ^^

Quadrant is pretty flawed. And I say that being someone who had a phone (before modifications) that was mid-range in Quadrant (Galaxy S), and having a phone that's right top of the heap (Galaxy S II)

moto xoom vs fascinate

Thought i would drop in and let you know the results of my testing, as I have a lot of downtime.
I used antutu benchmark as it would give me values for each category.
Moto xoom - 1.5 oc kernel, stock 3.0
Fascinate - voodoo eb16 kernel, superclean 2.7
Processor - as you all have heard the new dual core tegra 2 is fast, through same benchmark tests I have found that it twice as fast as the hummingbird w/ no over clock, the tegra was oc to 1.2ghz
Xoom 1034 and 766
Fascinate 596 and 142
Graphics - this is where some eyebrows will be raised! Everyone says the tegra is supposed to be the best at 3d but I found quite to opposite. There are a lot of variables out there too though, multi threadding and is 3.0 as mature as 2.2 and last the screen resolution is higher on the xoom.
Xoom 2d 148 3d 205
Fascinate 2d 158 3d 364
These results can be seen by the naked eye as things just seem slower on the xoom in 3d.
I did not include linpack as its obvious the xoom will out perform the hummingbird no questions. I am just thrown off by the gpu scores, anything out for the tegra the fascinae should be able to run, extra help will come from the faster processor but i am not seeing an incredible difference that was advertised. After these findings I am more excited for the dual core snapdragon. Things my improve as honeycomb matures and they iron out the details, from first use right now it seems like its a beta 2.2 that we had on the fascinates, its just not smooth. Over all if you want a good tablet w/ verizon 3g/4g the xoom is a good chipoice, those wanting a finished product, I would hold out a few mnths. Thunderbolt vs fascinae coming soon, as soon as the phone hits the streets. I will compare stock TB to modded fascinate, for those considering the upgrade.
Final on the xoom, it is a good tablet, maybe expensive
forgot to include wifi, another big dissapoitment, xoom being 4g upgradeable, I thought would kill it, it did not.
Netgear wireless n router, 12mbps line
Xoom - 2mbps
Fascinate - 6.5mbps
Hopefully an update will fix that
Well, the fact that most benchmark applications, besides Smartbenchmark, are not optimized correctly for Tegra2 puts these benchmarks to shame. Nenamark caps at 30fps, Quadrant caps at 60 or 30fps, and 2D benchmarks cap at similar fps as well. Real world speed is faster, as well as games optimized for the Tegra2. Though, movie compatibility with the Fascinate is better because of the extra codecs courtesy of Samsung. Not sure whats wrong with your Wifi..
Hitting fps caps is not in the cards right now quadrant hits 6fps 2d and about 20 3d, maybe when its optimized it will reflect capability better but now it just looks like its close. Everyday useability, my only compplain is the keyboard is sometimes laggy in the browser, most likely will be patched in an update.
I have both. And its too early to do a fair comparison. Apps haven't been optimized for the xoom.
I'm just bummed out that i can't use my fascinate to tether the xoom. I'm stuck paying for verizon monthly bill until the fascinate offers wifi infrastructure not ad-hoc. or switch to a phone that actually offers it.
You can get 3g mobile hotspot free google it

I think partially the difference comes from the higher resolution on the Xoom. But we do have a great GPU indeed.

Low Benchmarks scores

I know about the differences in benchmarks and how they arent set up for dual core, but I just ran smartbench 2011 and my gaming score is off by 1000 points on a stock xoom, I am rooted and running stock kernel. I am not sure why, maybe something is wrong with it.
My quadrant scores are lower than my dx but my linpack score is 64mflops! Don't know why our quadrant scores are so low but I'm having the same problem.

Off from what? A phone? Synthetic benchmarks say almost nothing about real world performance, and they will always be different with devices at different resolutions.
A 1280x800 tablet will always score unusually low on a graphics benchmark that scales to resolution compared to a phone.

Quadrant also places a lot of weight on the filesystem, and my Xoom always hangs quite a while during database writes.
Also I think that getting ~6 FPS on their first 2D animation test can't help.
The Xoom is really zippy, take the benchmarks with many, many grains of salt.
I was just talking about smart bench, everything else is working fine, but the smartbench 2011 shows a galaxy s as being more powerful than my xoom, and the half the speed of a stock xoom. I am just wondering if other people were showing that they are below what a stock xoom should be too.
you have to make sure that these benchmarks are compatible with dual core processors. otherwise the results are moot.
I know that, but it is shows below the average xoom, thats the problem I am seeing, average xoom gets like 2k I get 1k
I was having the same issue, I believe it is because of spare parts for gaming full screen. I factory restored my xoom and scored higher than average. The benchmark ran on a much smaller screen when I ran it on a fresh xoom.

Confirmed that is it, thanks for this I guess I was overlooking it and thinking my xoom wasnt up to par.

3.1 Quadrant drop

After updating to 3.1 I ran a few quadrant tests and instead of the 2000-2100 scores i normally get i am not getting 1500-1600 ... Usually updates boost performance not lower it
so i guess that begs the question: is your TF's performance lower?

quadrant came out and has not been updated since the nexus 1 got 2.2. so its kind of flawed and old. current best benchmark is either Vellamo or AnTuTu
Vellamo is a web browser benchmark IIRC, where as Quadrant is a CPU/GPU benchmark. I dont know about the other one you mentioned.
15xx is pretty damn low, I'm getting around 35xx with Quadrant at 1.5 GHz. Check your clockspeed in setcpu to make sure nothing is out of wack.

I think your sarcasm meter is broken.
...
Quadrant is broken because it doesn't weight different aspects of the benchmark equally. The Nexus One has a terrible GPU but a fast CPU, so it gets decent scores. The BN Nook Color has a mediocre CPU and a decent GPU so it scores better than the N1 even though the N1 is clearly the superior device.
Changing the file system to something journaled can bump your Quadrant score a few hundred points, which is dumb.
The ideal benchmark would somehow score in a way that represented the overall user experience. Unfortunately, no such benchmark exists for Android. Until then, it's just these pieces of crap that only exist so teenagers can show off their e-peen on the internet.

Only thing worst than benchmark nerds are benchmark nerds who are stupid enough to still be using quadrant software that's over a year old and is not optimized for dualcore or honeycomb.

A510 Quadrant scores average 2650- Now the average is 3720

Update: NOW the tests show 3720 average, so not sure what is going on....
I have done a bunch of tests and the average is 2650: Range as low as 2500 and 2760 was the highest. I thought people were getting about 1000 higher than that?
Been using the newest version of Quadrant and restarted the A510 as well and see no apparent signs of slowness and emulators & media play great. Something is not adding up here. Without doubt the 510 is faster than my Thrive, but that is not saying a whole lot (Tegra 2 is nearing two years old).

I tweak the kernel of the A500 on ICS and the quadrant score is 2500-2600
But don't look to hard on the quadrant benchmark , it's probably your I/O score that is low.
