  • Reason why AT&T's version of the HTC One X is not quad-core

Reason why AT&T's version of the HTC One X is not quad-core

Reason why AT&T's version of the HTC One X is not quad-core
We now know that the international version of the HTC One X will carry a quad-core NVIDIA Tegra 3 processor while the AT&T version for the U.S. will not. The latter model will be powered by a dual-core 1.5GHz Qualcomm Snapdragon processor instead. On the other hand, the international model will have HSPA+ 42Mbps connectivity vs. the 4G LTE support for AT&T's model.

No Tegra 3 processor in this model

No Tegra 3 processor in this model

We can imagine that many of those who had been following the HTC One X since its days as the HTC Endeavor had hoped for a U.S. version of the phone, but feel cheated somehow with the AT&T model. Before you start attacking the carrier, AT&T had to deal with a limitation imposed by the use of LTE support. It seems that the NVIDIA Tegra 3 is not compatible with LTE technology. So AT&T had a choice, they could stick with the HSPA+ connectivity that the international version uses, and keep the quad-core NVIDIA Tegra 3 under the hood, or they could go with LTE connectivity and use a different processor. AT&T, of course, went with the latter.

Despite having its hand forced by a technical issue, many might question AT&T's decision considering the paucity of LTE coverage that the mobile operator  offers at the present time. Not much will change before the phone is launched in the States which is expected within the next 60 days. We are sure that there are some who feel let down and will now look elsewhere for their next upgrade. On the other hand, the specs are still beastly no matter how slice it. Looks like AT&T customers will have as tough a decision to make as their carrier had.

It appears hauwei has a quad core that can do LTE. Bring that to verizion. Without quad core this phone really isn't much better then the rezoned and I would take a droid razr maxx over this in a second.

(Not to mention since at&t has such a small lte network they should of just stuck with hspa+ and tegra 3 combo)

This is supposed to be using Krait instead of the half baked scorpion. Hopefully it's as good as it's hyped up to be. Also the quad core tegra3 isn't all that great either seeing how it's based on Cortex A9.

Please someone bring the dual/quad Cortex A15 based chips to mobile devices this year

Ok well to my knowledge the s4 is an a9 equivalent so how does that make it better then the tegra 3 or what hauwei has. The facts is why get a dual core when quad is already out. Its watered down version of a better phone.

Your 'knowledge' is incorrect. The S4 is a generation ahead of the Tegra 3, and keeps up with it in every way possible. (and with three less cores to boot)

There is nothing to fret over because performance on the two will be the same.

What? The Tegra 3 processor is basically 4 A9 Cortex processors with a 5th companion core. Krait is similar to a Cortex A15, though it's not called that since it's Qualcomm's own design but uses ARM's instruction sets. Furthermore, the processor has proven in tests to bring out the most potential of dual-core processors to date (TI has only showed a snippet of its new dual-core processor performance). The Adreno 225 is very similar to the SGX543MP2 in performance if not better. So, it's not a bad replacement at all.

Here's more info on the Krait chipset:
http://www.anandtech.com/show/4940/qualcomm-new-snapdragon-s4-msm8960-krait-architecture

And here is some of the performance benchmarks:

http://www.anandtech.com/show/5563/qualcomms-snapdragon-s4-krait-vs-nvidias-tegra-3

As you can see, the Tegra 3 is only good at some gaming but it may be because VSYNC was on.

down with Krait version1

guys, just a hair after they launch this phone, they are relaunching Krait with the 3xx series GPUs which bring a 2-4x performance boost from this version of Krait

You guys keep wanting to say Krait is an "A15", when its not. Its still more comparable to an A9 right now. Its about 30% better than the basic A9 specs but its not up to A15 snuff. Its about on the same level as the A9 exynos 4210 (galaxy S2) in power/GPU/ proposed battery usage.
Once it has the Adreno 3xx GPUs in it, then it will be more comparable to an A15. Just like I keep saying.. over n over. This first chip is a place holder to "be one of the first". The good S4 chips wont be here till later this year.

31. Dr.Phil (Posts: 893; Member since: 14 Feb 2011)


You are right that it isn't comparable to an A15 yet because the GPU is still their old design, but the processor is still built on A15-like design. At least, that is what I have gotten from reading. I agree though that this was just their way of trying to get out a chipset faster than the competition.

@remixfa, the next best SoC is always right around the corner to be released. Between all the different SoC manufacturers it's impossible to settle on ONE super amazing chipset that has EVERYTHING (LTE, smaller fab, best graphics, etc.). Keep in mind that not everyone is playing Tegra 3 rated video games on their phones 24/7.

Not a hair, they're launching it about a year from now, and a year is going to be enough to resolve issues that are keeping clocks down.

2 GHz dual/quad core Kraits with Adreno 320, anyone?

then prove me wrong.

@willard,
no your right.. for the general public the chip is just fine. Its around as powerful as an exynos now, which is great. But we are not the general public. We are the people that wait with baited breath when new tech is released. A good few of us argue over specs between manufacturers. Its not about the constant cycle of electronics. Its about finding the best available this year thats going to last another year to 2 years. From my understanding they said these phones will be available in "a few months", which puts them just before the rumored SGS3 release timetable.
If it came down to a 30-60 day difference between the launch of this and the SGS3 with its (rumored) quad core exynos, much stronger GPU, new samsung screen tech, and more than likely better battery life.. would you wait? A lot of people would. They sure as heck did for the SGS2 and its what..5 month delay.

That and this chip is a stopgap.. and I hate stopgaps. Give me the real deal or get out of my way. :)

1. I check my links, and Semiaccurate is rather famous for having moles that are terrifyingly accurate. T3 running on single channel memory is a stopgap, S4 at 1.5 GHz with Adreno 225 is a stopgap, but you seem to be fine with Tegra 3. The discussion is not about whether Tegra 3 is equivalent to Snapdragon S4, the discussion is focused upon whether Cortex A15 and Snapdragon S4 will be better. There is some evidence suggesting that the S4 is faster, some evidence that Cortex A15 is faster.

Tegra 3 is poor design, as soon as they had to go to a combined 40nm LP and G process they failed. The lack of integrated modem is bad design. The bandwidth starved SoC is bad design. Yes, the SoC may be fast, but Huawei and Qualcomm already made a better SoC that does everything Tegra 3 doesn't.

2. Ha, suggesting that I thumb myself up.

54. remixfa (Posts: 13902; Member since: 19 Dec 2008)


your link doesnt link to what you think it links too.. that was my point.

If you read my posts, i call them both stopgaps. Between the 2, the T3 is the better chip. Your comparing reference vs commercial. Wait till the S4 is in a commercial phone, then come running with benchmarks.

All evidence points to true A15's being faster. There isnt a single true A15 on the market to compare it to. Its being compared to A9's from last year and just barely edging them out. Thats an improvement for sure, but its not impressive when you know true A15's are right around the corner as well.

Again, they are BOTH stopgaps. If I HAD to have one or the other, I would take the T3. For what it marginally does worse in the S3 REFERENCE board with, it still stomps it with GPU and is still capable of doing many graphical things that those little bar graphs dont show off. As android apps get heavier and heavier, the extra cores of the T3 will help keep it relevant longer than the S4.

The S4 is OK when compared to last years chips. It is however still CRAPdragon when you compare it to THIS years chips. It will find itself at the bottom of the benchmark pile before the end of 2012. That is a fact.

There are quite a few around here that thumb themselves up, its not uncommon. :)

Krait is better at EVERYTHING besides some very specific use-cases that NO user will ever encounter on a phone. Literally, the only thing it is better at is in heavy, heavy multi-threaded applications, and even then, its only ahead by a little bit.

OI.

do we need a taco check?

@mario,
yes I understand they are getting the S, but it doesnt answer the question. They can easily have the T3 in the S as it is HSPA+ 42mb capable. I just think its a missed opportunity for Tmobile.

Droid,
The exynos 4210 processor was not built to support LTE or HSPA+42mb/s which is why American carriers are swapping it for an S3 for those capabilities. It wasnt an "issue using it".. it was just not compatible. The only Achilles heel on an otherwise impeccable chip.

I am happy they chose the s4 instead of the tegra 3. The S4 will be far more power efficient too because it has the built in support for LTE. It would be nice to have the raw power of a quad core cpu but with only an 1800 mAh battery it wouldn't last long enough.

Is there anybody else besides me that is worried about the screen & physical size of these so called "smartphones"? I saw on phonearena where this thing has an 1800 mah battery. I can't get through more than 10 hours or so on my Captivate with a 4.0 inch screen before it dies. Reading about the Samsung Galaxy S II and other phones with larger batteries it not much better.

I know of no phone on the market that is 2.75 inches wide. Thats quite large (wider than razr Maxx) and I don't believe the batter will be big enough to last any kind of time. If i'm on vacation and I leave my hotel at 9a and don't return until around 6p or so, the last thing I want to worry about is my phone being dead when I'm in an unfamiliar place where I may be using a lot of data.

I think it is totally fair to diss AT&T on this, because HSPA+ is here and now, most customers benefit from this. Tegra 3 is here and now, most customers benefit from this. LTE is not here and now, if we're lucky most of the US will have LTE coverage by end of 2013, by that time the person who buys this phone at launch will almost be elig to upgrade again anytime, so they'll barely get to use the LTE on this phone if they dont get it until then.

The XL (with LTE) also has HSPA+ for the ATT network... so you get HSPA+ AND LTE (if available)... wait for the X and XL to come out and we get some real life benchmarks before you make assumptions.

There is no tough decision to make, IMO. I'll be leaving ATT and picking up the first carrier that offers a Tegra 3 device with HSPA+ connectivity. It doesn't seem likely that AT&T will achieve 42 Mbps on any device, LTE or not. I love my Tegra 2 device, and I don't want to wait. I don't understand why ATT didn't at least offer both Tegra 3, and LTE equipped devices, and let the consumer decide. AUHHHHG!
