[T-Mobile LG G2x] thefreeaccount2:
I don't think you understand what people are saying. Tegra 2 is an integrated CPU/GPU, so both must share the same memory bus. In order to draw the screen, the GPU must iterate over every single pixel multiple times, at least once for every layer of graphical effects (1-4x for iphone, ~6x for android). At 60fps, this means 32-bits * 800 pixels * 480 pixels * 60 frames * 6 * 2 (1x send data, 1x receive data) = 1.4GB/s.

The Tegra 2 has only 2.6GB/s total bandwidth available, which means just over half the bandwidth is gone and we have done nothing have the OS tell the GPU to display the screen for one second. Then the CPU must do its work and the GPU must add any extra effects the application wants on top of that. The same memory bus must be used to juggle memory between CPU cores, when they need access to the same memory location. More cores = more bandwidth.

Consider that Apple's "version" of the Tegra 2 has 17GB/s of bandwidth, or *over 6 times* the bandwidth of the Tegra 2. There is nothing theoretical about this; Tegra 2 is absolutely bandwidth starved in practice, especially when running on a davilk/Linux, both of which assume that bandwidth is infinite and simple instructions have little to no cost (Not true on ARM or integrated CPU/GPU!).

Adding to this problem is the lack of NEON, which means that simple operations such as image scaling can not be properly hardware-accelerated on Android. The reason is obvious - NEON requires out-of-order memory access and Tegra 2 simply can not keep the GPU fed with data fast enough.

T2 is not gimped by proprietary drivers or any sort of artificial limitation. It is held back by the fact that it is simply a low-quality design, skimping on just about everything to give the lowest possible cost and highest possible "on-paper" performance per watt. The only reasons that Tegra 2 enjoys such a positive reputation are Nvidia's marketing budget and army of loyal "supporters."

No one is complaining about pure integer performance. We are long past the point where DOM parsing matters, anyway.

Your wrong stop with this theoretical and scientific **** and do some real world comparisons then you will see that the g2x beats all
[T-Mobile LG G2x] mysterioustko:
First of all, memory bandwidth plays a large role in device performance. This isn't like those benchmarks, this is actually what the device is capable of doing. Second, in real world comparisons the lack of memory bandwidth shows. Like I said earlier in this thread, go to a flash heavy site or stream hd video, and you'll get a very clear demonstration of things getting bogged down, as opposed to phones like the galaxy s2 (exynos) that handle it MUCH better. BTW, that's without me even counting the slowdowns that the device just tends to suffer from at times also.
[T-Mobile LG G2x] Dvicens:
This turned into a great thread, i completely agree with you. Flash player runs TERRIBLY slow on this thing. This whole time i thought it was the actual flash player. Now reading this it makes sense why the GS2 runs EVERY flash video i watch without any hiccups.
[T-Mobile LG G2x] EEngineer:
Look, freeaccount & mysterious, you are both making sweeping generalities based on a handful of published specs without looking at the actual architecture. For example, does the Tegra 2 support Burst Mode DMA transfers? That would radically improve bandwidth performance (when spec'ing memory bandwidth, it is considered dishonest to use Burst Mode for the memory bandwidth spec). Most likely the GPU draws the screen with the DMA.

For an accurate understanding of the architecture I would have to look over the Tegra 2 datasheet for at least an hour and that is time I simply do not have.
[T-Mobile LG G2x] ridearoundsolo:
I love how people knock on this phone, its no where near as bad as its made out to be, if u all hate it soo much why waste time postin here, its sad how much free time u haters have,

Dude get a life the rest of the world dnt care, the g2x is badass and a snappy fast

[T-Mobile LG G2x] mysterioustko:
I see a question and a speculative statement, but nothing fact based. I've given you something factual and gave you a real world example of how the lack of memory bandwidth shows itself. If you have something to show that contradicts this, then I'd love to see it as I'm always open to learning something new. One thing is for sure, the tegra having less than half the memory bandwidth of competing a9 chips does put it at a disadvantage....oh and don't forget..IT CAN'T EVEN DO NEON INSTRUCTIONS EITHER! It's a handicapped chip with great marketing. Nvidia does a bang up job of making sure their brand is synonymous with great performance. However, in reality it definitely is not the king of the hill, I'd put it at 4th best or at worst 5th (an argument could possibly be made for the S3).

Let's try to keep the level of immaturity in the thread to a minimum please. We are having a pretty decent discussion on this chipset and I personally would like to continue it. If you don't have anything constructive to contribute then please move on. We don't need personal attacks and immature behavior. Thanks.
[T-Mobile LG G2x] krolla03:
What the hell is the point of ths thread? The G2X although not the most up-to-date phone is still a pretty good one.

Hell radioshack and cartoys are still promoting the HTC Inspire and Samsung Infuse on TV a WAY outdated and discountuned phone.
[T-Mobile LG G2x] EEngineer:
Correct. Because without the Tegra 2 datasheet, all we can really do is speculate, right? I've actually written processor datasheets so I see these things differently. I know how partial specs can show a grossly inaccurate view. Sometimes it's done on purpose to hide information from your competitors.

Look, your math is good and your assumptions are sound, but they are based upon partial specifications. Your conclusions are correct based only upon the data at hand.

Does the Tegra 2 support burst mode transfers? What DMA modes are supported?

Because if it does, then it might solve your performance concerns. Without examining the datasheet, all we can do is speculate.
[T-Mobile LG G2x] Core Memory:
Technical minutae aside, although I like the phone, despite all of its problems, the biggest problem with the G2X and Tegra2 is LG and NVIDIA not providing the information needed by developers to fully utilize the phone and the GPU. The Tegra3 is more powerful than the Tegra2 but that doesn't matter because of the same reason. This is why anything with NVIDIA will lose out to products with chips from companys such as Texas Instruments which Open Source the necessary information and why Google has ditched NVIDIA, they're too damn hard to work with. That's also why this is the last NVIDIA chipped phone or other device I will ever buy regardless of which company puts NVIDIA in their device(s).
[T-Mobile LG G2x] EEngineer:
I completely agree.
[T-Mobile LG G2x] mysterioustko:
I agree whole heartedly. The G2X was my first and last nvidia powered device (and lg device for that matter). The reasons you listed above also have part to do with why I feel this way too.
[T-Mobile LG G2x] EEngineer:
Yeah, the lack of drivers really pisses me off, too.
[T-Mobile LG G2x] Core Memory:
NVIDIA should suffer the same demise as NORTEL did and what RIM appears to be too.
[Samsung Galaxy Nexus] atiasdudi:
Got my GN few days ago and i absolutely love it!

everything is buttery smooth but Ive noticed a little lag/stutter when i go to the recent call log on the phone app, swiping down to get to the bottom.

it only happens the first time (when u get to the bottom of the call log, after that everything is smooth again)

and i can exit out of the phone app, get back to it after 1-2min and its still lag-free, but if i come back after lets say 10 or so min, even if i didn't closed the phone app from the multitasking menu - it will stutter again (tho again - first swipe only)

now, when u go to people app and scroll the whole contacts (i have 400+ there), its smooth every single time! even when closed in multitasking menu or even when opening it after long time.

did anyone noticed that or is it just my device?
[Samsung Galaxy Nexus] Chrono_Tata:
Yeah it's normal don't worry. They are probably cached at different priorities.
[Samsung Galaxy Nexus] atiasdudi:
any way of forcing it to cache phone app at higher priority?

hope to solve wifi-camera issues sooooooooooooooooooooooon
[myTouch 4G Android Development] tnpapadakos:
nice work! thanks alot:)

trying it out now

1. cant find how to get desktop wallpaper to scroll on this launcher

2. cropping an image to set as wallpaper very dodgy, ie., screen flashes/gets messed up, but if you keep tapping on it and trying to crop, you can eventually get it to work

3. seems like in-call microphone is a little low, people on the other end having a hard time hearing me

4. had the screen shut off animation working, but now it doesnt

5. of course, no wifi, no camera

will report back anything else i find
[myTouch 4G Android Development] guttus:
Having the same in call volume issues. Volume is so low that the person I call cannot hear me at all. Even when I'm yelling.

Other than that this amazing. Thanks to all who are taking part in this.

[myTouch 4G Android Development] NatsuDragneell:
Nice to have this build back up and running thx Feb. :D
[myTouch 4G Android Development] tnpapadakos:
works with normal animation and "normal" transition speeds (in spare parts, downloaded and installed it after flashing rom) does NOT work with animation and transition speeds on "fast"

bluetooth works to stream phone call audio to car, but no other media is streaming via bluetooth (A2DP)

oh, yeah, calendar not syncing with google account
[myTouch 4G Android Development] oak25:
My wallpapers keep resetting to a black background automatically after the system crashes (expected). Also, is anyone experiencing late text messages? Has anyone tried the labs option in the internet browser? If so I believe the full screen feature in where the user has to slide the thumb from the corners in order to get the short menu is being cut off, maybe a re-sizing issue? Lastly does that feature have a proper name? Thanks.

I know people have mentioned the calendar syncing but I remember that in the second build with data working, the calendar was syncing properly. (just throwing it out there)

Pretty nice to whip out my phone and say "look at my YouTube widget!" (iPhone user: what is a widget?, siri: "IDK")
[myTouch 4G Android Development] jaysun3000:
I went back to my favorite ROM from the build from source for time being I will be back tho cause its really nice.....I just could not do without my headphone Jack....I got the same wallpaper issue with the background going black it happens when the screen rotates I think....also the issue with the cropping of pictures where the screen was unreadable...does anyone use Orbot because I could not get that to load either I use it quite often and is a must for me....i still think the market is a bit wonky...
[myTouch 4G Android Development] chukis13:
Did you guys try flashing these gapps with it? They fixed my calendar.

[myTouch 4G Android Development] richdaley:
Great work on the wifi! This rom is almost ready for prime time.

I am also getting errors when downloading apps from the market and talk force closes on me. I tried clearing the market data and stopping the market and google framework but no dice.

Youtube worked for me. I can't test other video playback because all I have are avi files and I need to download a player from the market to play them.
[myTouch 4G Android Development] my2sense:
Just did a full wipe and mobile data is not working for me. Wifi works. Tried re-enabling mobile data but no dice. Calls work fine.

Market is also not downloading either.
[myTouch 4G Android Development] Jbazt_katuforzs:
wow!!! this is what im waiting for!!! you saved my day with that wifi fix man!!! gonna test this one all day long tom and will report my complete feedback!!! :D
[myTouch 4G Android Development] pompeiisneaks:
I agree with findings,

Working now: Wifi

I don't have problems with cellular data, but market won't run.

Home button wakes but middle mousepad doesn't wake phone. (sorry I misread original post, home and menu work, I personally liked the old way of Home and the mouse button press to wake but menu does work, bad me)

Market runs but I can't install facebook app at all still.

Youtube is working, but talk still FC's as well.

News and Weather app seems to load news fine but can't load the weather app. Says "Sorry, weather currently unavaiable."

oddly I installed the gapps zip you provided last time (I don't know if I'm supposed to re-download for beta 4.0 because the link still seems to say the same name) and g+ and other apps like that were available last time but are not now.

USB is still not working, unless I boot into recovery.

This may be a repeat of what everyone's saying, but I wanted to report as much as I could find as well, to add more data points.

Thanks for the awesome work! WIFI is working, I'm stoked!

Edit: Just called my wife on it and she reported weak mic, hard to hear sound somewhat intermittent in and out in volume levels. Nobody had told me that before but I've seen it reported before so I wanted to add that as well.

[myTouch 4G Android Development] daniETingles:
oh okay awesome! :) because i remember reading something back a few pages about a stock experience/launcher, lets hope the stock launcher runs smoother and has less fcs then trebuchet eh? o:
[myTouch 4G Android Development] ARey1212:
Hey feb,

I think it would be best if you could perhaps release the next beta version with the semi working camera (if you have one) that way we could report log cats and findings with the camera. I'm sure your agenda is the best but just offering a suggestion. Thanks for everything again
[myTouch 4G Android Development] simplyrafa8:
Don't forget Feb DOESN'T have to release any roms, he can stop whenever he wants, it's his choice. So give him time everyone, just let him work, it'll come :-)
[myTouch 4G Android Development] daniETingles:
dont worry we know this, many of us have been active on this thread for a long time! what I'M worried about is that this rom will be getting less and less attention as more and more people focus on the miui v4 ics rom, but febs already done some amazing work so far, so who knows! :)
[myTouch 4G Android Development] simplyrafa8:
I've been following and giving thanks since day one, it's been going great and the speed of the development is just amazing! And yeah I agree, as much as I love MIUI, I'd rather have a stable stock rom for our phone!

Hey Feb, were you able to look at the virtuous quattro settings in the status bar? It'd be awesome to see in your rom if its not a problem, if it is, don't worry about it. I was just thinking its a clean and simple change from how cyanogens are set up.
