I've got to disagree here. At this point, hardware wise this phone isn't all that impressive. The tegra 2 is around the bottom of dual core processors, the phone only has a half gig of ram, and it's a lot res screen (with excessive bleeding). It's probably only the 4th best phone on T-Mobile and not even a top 10 phone in the phone market. The tegra 2 was great when it first hit the market and there were no other dual core processors to compare it to, but that has since changed. The tegra 2 is at the bottom of the totem pole when it comes to dual core processors. It's certainly nothing special.

[T-Mobile LG G2x] FatalityBoyZahy:
Have you seen how the G2x compares to most phones in real world performance? It blows most of them away... "Low Res Screen"? It's an IPS display... With the same resolution as the GSII.... IPS > Super AMOLED Plus IMO.

And you don't need more than 512mb of RAM, although it would be nice.
[T-Mobile LG G2x] d12unk13astard:
...and with ics just around the corner it will continue to bully other "so called better phones"!!
[T-Mobile LG G2x] ericalanMICHAEL:
If we're comparing performance of dual-core chipsets, Tegra2 is hands down one of the best on the market. I have no idea where you're getting your information. It absolutely kills Snapdragon processors and others trying to compete. The closed drivers is a downside but performance-wise, this phone blows other out of the water, including those 1.2Ghz+ processors (MT4G Slide, Sensation, etc).
[T-Mobile LG G2x] mysterioustko:
I would even go as far as to say it "kills" the snapdragon processors. It isn't head and shoulders better, and as for the other dual cores it definitely isn't better. It only has less than half the memory bandwidth of the exynos 4210, omap 4460, and the A5 (2.4GB/s vs 6.4GB/s). Processing power does you know good if you don't have the memory bandwidth for it to travel on. The S3 has 2.7 if I'm not mistaken, but it's running on A8 architecture so you could possibly give the Tegra 2 the edge over the S3 despite the fact it has less memory bandwidth, but when it comes to the other dual cores, it doesn't compare.
[T-Mobile LG G2x] ericalanMICHAEL:
I disagree. All technical specifications come second to real-world performance. People flocked to the Sensation and MT4G Slide because, at their release, they had a higher Ghz rating than the G2x. And Tegra2 is undoubtedly faster than the Sensation.

Obviously, there are better phones out now. But Tegra2 is still above most, especially for gaming. Quadrant has me 100FPS and higher continuously when overclocked, getting 5k+. Other processors just don't compare.
[T-Mobile LG G2x] ZeroT| Demented:
have you ever looked at a comparison of benchmarks between our phone and phones like the gs2 the tegra 2 is still very much one of the best chips in any phone
[T-Mobile LG G2x] mysterioustko:
So are you saying you don't think that memory bandwidth matters?
[T-Mobile LG G2x] g2xkid:
You got to be kidding me!!!! No more weed for you!
[T-Mobile LG G2x] mysterioustko:
Tell me specifically why you disagree. Here's what I think, on T-Mobile the GS2 and the Amaze are better, and I can make an argument for the Sensation and the Nexus S. So at best it's the 3rd best phone on T-Mobile and at worst it's 4th.

In the overall phone market I put several phones ahead of it. This is in no particular order but the Galaxy Nexus, Galaxy S2, Rezound, Razr, Bionic, Amaze, Atrix 2, GS2 Skyrocket, Nitro, iPhone 4s (yeah I hate saying that too lol), and like I said I can make a case for the Sensation and the Nexus S, but even without those 2 that's 10 phones right there. The G2X was great when it came out because it was the only dual core processor available, since then better dual core options have come out. The tegra 2 is on the low end of the spectrum. Like I said earlier in the thread, it has less than half the processing capability of the exynos 4210, omap 4460, and the A5 due to the small amount of memory bandwidth. That's a pretty big minus. Is it a terrible phone? ...well due to bugs yeah probably, but the hardware isn't terrible, it just isn't top tier. Low res poor contrast screen (with bleeding issues), low amount of ram (and it's possible this could show itself more in ICS...whenever it actually gets it), dual core processor with very low memory bandwidth, no next gen features (nfc). There isn't anything about this phone that makes it stand out (except bug problems). The one thing it had that stood out when it came out was the tegra 2, but at this point a tegra 2 is only 3rd best, and some would argue 4th best in the dual core world.
[T-Mobile LG G2x] r4d14n7:
It's not that memory bandwidth doesn't matter. It's that the swapping doesn't seem excessively slow on this phone. My phone has no bleed and has rebooted a total of 3 or 4 times since I bought it in April. To me, excellent purchase. Would only swap for a next gen nexus device. And even then, I might not take the bait.
[T-Mobile LG G2x] Core Memory:
The power of the p999/G2X was held back by the lack of hardware acceleration in Android and it remains that way because of NVIDIA's intellectual property rights paranoia which I think may also have to do with the potential for bypassing digital rights management. That would be remedied if the full documentation of the Tegra was publicly released and LG provided updates in step with Google's releases of Android or shortly thereafter. When ICS is available for this phone, the hardware acceleration will be implemented which will make a big difference to its operation. I do agree that there are some hardware limitations which limit the phone such as the minimal built-in memory, bus bandwidth, battery life, etc., which, depending on the type of usual use, will affect some users more than others. Even with its limitations when running ICS it will be more than enough phone for most people at an excellent price. It's unfortunate that this phone is the Rodney Dangerfield of handsets.
[T-Mobile LG G2x] jnralp00:
You are crazy!!! How many of these phones have you personally compared to a g2x? I'm not nuthugging but you just keep saying the same crap over and over and it makes no sense. g2x's performance is still at the TOP of the spectrum... when it's running properly:o
[T-Mobile LG G2x] mysterioustko:
Actually I have used all of these phones. The Nexus S, G2X, Sensation, Amaze, Galaxy S2, and Galaxy Nexus I have used for extended periods of time (daily driver), the others I used for shorter amounts of time but still long enough to get a feel for them (I'm a bit of a cell phone junkie, and I buy and cell on Craigslist very often). That being said, yes the G2X can tend to get a bit bogged down, as does the Sensation, and to a lesser degree the Amaze and Rezound. The difference between them mainly being that the G2X gets worse battery life than the 3 I just mentioned. As for the other phones that I named earlier, they clearly run better than the G2X, and it definitely shows itself in web browsing heavy content and streaming hd video, especially when you bring flash into the equation (GNex being the one exception since flash isn't on ICS yet). In basic use, sure it runs just as well as it's competition, the problem comes in if you do anything that pushes it, you can definitely see it bog down, which I attribute that to the lack of memory bandwidth. Having a processor and gpu that has super performance does no good if the information has nowhere to travel on (memory bandwidth), that's why it's so important. G2X is 32x vs the other A9 phones that are 64x, it's at a very large disadvantage then add to that the fact it has half the ram.....that's not very good. Tally up the score, the G2X has half the RAM and less than half the memory bandwidth, not exactly built to outperform anything. BTW, no offense but people such as yourself keep posting that they disagree with me, and saying the phone can perform but nobody has backed anything up with any facts to support their OPINION.
[T-Mobile LG G2x] Core Memory:
Does it really matter that much when the performance is adequate enough to do what one needs? For example, most people pay for capabilities which they won't usually use, a lot of people with smart phones use them as telephones, cruise the net minimally, read email, text, ocassionally use the camera, play music and watch you tube videos a bit and play a game or two. The G2X is quite capable of adequately doing that and, when ICS is available, more than adequately. The phone spec bragging rights are meaningless to most. Fighting over which phone is the best, almost the best, better than some other phone, etc., is very immature.
[T-Mobile LG G2x] mysterioustko:
First, nobody's fighting. I'm simply pointing out a fact. And yes for basic tasks and for average use it is adequate, but then again so is an Evo... For me, I do not find it adequate as it tends to get bogged down if you push it, then add in the bug problem and I find the G2X to be a very average phone. Do I think it's a terrible phone? Actually yes I do, but that's more to with the instability more than anything. As for the hardware, I find the hardware to be very average, not the mind blowing behemoth some of the people in this thread would lead people to believe. BTW, something like memory bandwidth isn't just a spec to brag about, that actually effects phone performance a lot...especially when you start talking about browsing flash content or streaming an hd video. Times like those, memory bandwidth is very important.
[T-Mobile LG G2x] ericalanMICHAEL:
I'm enjoy an honest debate. But that kid you quoted started his post with "**** YOU". Like..for real? Don't take stuff so personally.

Anyway, back on topic. Nobody has posted "facts" to back an opinion because real-world performance isn't an opinion. Quadrant scores, speed tests, etc. are not opinions; they have solid, numeric, quantifiable results. Despite how much of a bad rep these get sometimes, they can really be quite accurate (FPS in Quadrant, UL/DL in SpeedTest, etc).

G2x runs ARM Cortex A9 which still performs better than

Sensation, Amaze, and MT4G all are running the variations of the Scorpion processor with slight differences (Amaze at 1.5 not 1.2, etc). Run a benchmark. Speedtests. Compare FPS, UL/DL, general user experience, and whatever among the G2x and other devices. G2x is not the top of the totem pole, nor is the technology necessarily cutting edge anymore. If anything, it speaks volumes about the plateau some companies are at right now.
[T-Mobile LG G2x] chris.wueste:
Agreed

Just throwing in my two cents. Tegra 2 is a fantastic chipset. Runs any game I have thrown at it at great frame rates. So glad I chose a Tegra 2 device.
[T-Mobile LG G2x] mysterioustko:
I'm the same way, I love a good discussion especially when regarding technology since I'm a bit of a phone junkie lol. As for that other guy, apparently he wasn't hugged enough as a child lol. Anyway, back to what we were discussing....I will agree with you when it comes to the Sensation and the MT4G since both of those are both underclocked to 1.2 and it shows (hence why I said I could make a case for it instead of just saying it's better). I'm not a fan of the Scorpion processor at all. The one thing I will give it is that it seems to perform comparably to the Tegra2 at 1.2 but with better power efficiency. At 1.5 it seems to do a little bit better (marginally), but power efficiency suffers greatly. All in all I feel the scorpion is a very average chip, it's almost like it's the poor man's dual core. Even with that, there's still something to be said about it handling power better. As far as benchmarks, I typically don't put too much stock into those since they are so easily manipulated. The one benchmark that I do pay particular attention to however is the Sunspider, since that pretty much does correlate to real world browsing. The Sensation did terrible in it, whereas the Amaze did pretty decent. As for the G2X, it didn't really impress. With the newer phones included it comes in around 10th or 11th. Overall, I think the tegra2 is an average chip, just slightly above the scorpion. I think a lot of people got caught up in the hype of the tegra2 and never really looked at it in a macro sense. A processor's raw power is only part of the picture. Memory Bandwidth plays a very large role in that particular chip's performance. If the memory can't handle the tasks the processor is capable of doing, then that processing power is wasted because there's a bottleneck at the memory, such is the case with the tegra2. This definitely shows itself when you do something like stream hd video or browse flash heavy sites. It even shows itself in that occasional slow down you see the g2x have sometimes, especially when multitasking (it tends to bog down, due to there not being enough memory bandwidth to process it all). Diane Hackborn said it best, "if you want to get an idea of the performance of a piece of hardware, always pay close attention to the memory bus bandwidth. There are plenty of times where the CPU (especially with those wonderful NEON instructions) can go a lot faster than the memory bus." https://plus.google.com/105051985738280261832/posts/2FXDCz8x93s
[T-Mobile LG G2x] Core Memory:
I agree with you that memory bandwidth can be, and is, the small end of the funnel. NVIDIA and the handset manufacturers which use the Tegra 2 chip should be ashamed of that, particularly when Dianne Hackborn, https://plus.google.com/105051985738280261832#105051985738280261832/posts https://plus.google.com/10505198573...8x93s#105051985738280261832/posts/2FXDCz8x93s, knows that and other problems, and NVIDIA didn't ensure that its Tegra 2 wasn't crippled by device manufacturer's design choices and required manufacturers to design their devices to facilitate the full capabilities of the Tegra 2. NVIDIA has no inTegra2y! Google should also be ashamed of itself for allowing Android to be used and abused in ways which undermine Android.
[T-Mobile LG G2x] mysterioustko:
I agree completely. To release a chip with less than half the memory bandwidth of the other A9 competition is a bit puzzling to me. Having a processor that's faster than the memory doesn't do a bit of good due to the bottlenecking that winds up taking place. Nvidia states the Tegra 3 will have up to 3 times the amount of memory bandwidth which would only put it at 7.2GB/s compared to the 12.8GB/s the Exynos 5250 will have. Bear in mind that current A9 processor like the exynos 4210, A5, and the omap 4460 all have 6.4Gb/s now, so the 7.2GB/s the tegra 3 is supposed to have isn't exactly impressive. It's still only going to be 32x as opposed to the 64x of it's competition. Interestingly enough anandtech shows the memory going up to 1500mhz, which would only calculate out to about 6GB/s. Here at http://www.ubergizmo.com/2011/11/nvidia-tegra-3/ they even voice a concern over the Tegra 3 having a limited amount of memory bandwidth saying "The frequency is a bit higher, but all in all, it’s not *that* different from Tegra 2. Given the increase in CPU cores, and pixel-processors, I am a bit concerned that the bandwidth may become a limiting factor at some point…", as does anandtech "The memory interface is still only 32-bits wide, resulting in far less theoretical bandwidth than Apple's A5, Samsung's Exynos 4210, TI's OMAP 4, or Qualcomm's upcoming MSM8960. This is particularly concerning given the increase in core count as well as GPU execution resources. " (http://www.anandtech.com/print/5072). All in all the nvidia seems to have dropped the ball yet again. I definitely will not be purchasing a tegra 3 phone at all. They increased the cores yet they didn't even match the memory bandwidth to what other high end DUAL cores already have. So now they will have a quad core processor running with bandwidth that was enough for a dual core processor. Sounds like a very inefficient processor, and more bottlenecking. Color me unimpressed.
[T-Mobile LG G2x] EEngineer:
If you access more RAM, the battery life goes down. RAM eats mA like a greedy goldfish.

The same with increasing memory bandwidth.

That's what a cache is for.

The Tegra 2 has a 1MB L2 cache. For critical code you load your code into the cache and run it from there.

I've designed CPU-based systems that ran faster than competing designs despite my system having a slower external bus. You don't need to access data FASTER than your competition, only FAST ENOUGH. It all depends on your memory design and how you have implemented caching. Even if the Tegra 2 has a slower memory bandwidth, if you design your memory architecture right you can feed the pipe and not miss a beat compared to other architectures.

You can have a VERY FAST external CPU bus that loads data quickly, giving you a high current consumption over a small period of time, or you can have a MEDIUM-FAST bus that loads data almost as quickly giving you a medium current consumption over a slightly longer period of time. You average the area under the curve and calculate your current consumption. You keep playing with the bus figures until you've found the bus speed and memory architecture that hits your design target.

Keep in mind, mysterioustko, that you are discussing processor design targets. We don't really know how fast the buses have been tuned to be in these actual systems, nor do we know real world reliability for these systems. You are obsessing over the CPU memory bandwidth without taking in the overall system (phone) design targets.
[T-Mobile LG G2x] iCraft:
Based on my current knowledge, I would think phone processors can be looked at with the same mentality as computer power supplies.

For instance a Corsair 500w psu would be better than some random 800w psu, because of the quality and efficiency of corsairs.

I believe the Nvidia tegra 2 can be thought the same way. It may have seemingly lower specs, but works just as good if not better than one that has higher specs, and isn't as efficient.

Atleast that is what I believe.
[T-Mobile LG G2x] Grooveoriented:
Wow - for quoting anandtech up there, you sure didnt take a good look at the benches in one of his other comparison articles. The Tegra 2 has been around for almost a year and a half. It's a javascript beast compared to processors that are even much newer. Granted, the SGSII or the Amaze isn't on these benchmarks, but here is what I was referencing. For someone to say they could argue a case for the Sensation is just ludicrous based on the benches referenced here:

[T-Mobile LG G2x] xHausx:
Each processor has their strengths and weaknesses, the Tegra2's weak spot is HD decoding while the snapdragon in the sensation handles it without breaking a sweat. But when it comes to benchmarks it seems like HTC couldn't care less about them.

The snapdragon in the LTE GS2 is basically the same thing that's in the Sensation and it benches neck and neck with, or even slightly faster than, the exynos.
[T-Mobile LG G2x] mackster248:
Well lets not get ahead of ourselves now. IPS is great and I'm happy with it, but there's no way it's even remotely close to the quality SAMOLED+ brings. I love how the blacks in SAMOLED+ are. Side by side comparison of my phone against my gf's SGSII isn't even a contest.
[T-Mobile LG G2x] EEngineer:
Depends on the video player you are using. I'm using MX Video and the quality compared to the G2X standard video player is amazing. MX Video supports Tegra 2 hardware decoding and on the G2X I'd put the video up against anything else out there.
[T-Mobile LG G2x] mysterioustko:
Benchmarks? Is this really going to be your basis for argument? If you want to look at benchmarks, then go pull Sunspiders and when you compile them the into one, the G2X doesn't even finish in the top ten (It's around 11th or 12th). That being said, using benchmarks as a basis of argument is inherently flawed. And yes I stand by my statement, yes I can make an argument for the Sensation. While neither phone is really fantastic, there are some things the Sensation handles better than the G2X and vice versa (hence why one could make an argument). At worse, they'd be on equal footing.

I'm aware that memory bandwidth is a piece of the puzzle. However it is indeed a large piece of the puzzle. Data has to have a path large enough for it to travel on, point blank. And yes when you look at the design of the chip as a whole it becomes apparent that it could indeed benefit from more memory throughput as it tends to get bogged down when completing more taxing tasks (ie. flash heavy websites or streaming hd video). This phone hangs in places where some competing devices do not. I can't help but to believe that perhaps if it didn't have less than half the throughput of it's competitors and only 32x memory as opposed to 64x then maybe it would fair better. Not only does the tegra 2 have this handicap, it seems that nvidia decided to keep the same memory format yet again in the Tegra 3, which places it yet again well below the next gen competition. That being said, I will not be purchasing an tegra 3 powered phones.
[T-Mobile LG G2x] EEngineer:
Well, I've never had my G2X hang. I've never had it hang on streaming HD video, either, but I use MX Video player because it blows the default video player away.

Maybe I've got it configured differently than you. I also have a Class 6 SD Card and according to CyrstalDiskMark it makes a big difference in phone performance.

And I don't play games on my phone - if I'm out with people, I'd rather be with the people rather than play with my phone.

You seem to be engrossed in what's called "specsmanship", but the examples you are giving are all subjective and subject to the configuration of your phone. For example, you write "when you look at the design of the chip as a whole it becomes apparent that it could indeed benefit from more memory throughput". It's not "apparent" to me. If one of my engineers made that statement to me, I would respond "Well, it's not apparent to me. Show me the phone's system specs and a bus example". And let's not even start talking about bus arbitration or I'll never get back to work :cool:

BTW, the A9's L2 cache can send prefetch commands to the memory controller. (For instructions, I THINK it fetches two instructions at once.) So, if you manage the L2 cache and the MMU properly, the A9's pipe should never have to wait for data. Period.

It's like the guy trying to sell me a 2GHz chip because it's faster than the 1.5GHz chip I'm using. Meanwhile, I've got the system running at 1GHz because that gives me the realtime performance I need without wasting the battery.
