Qualcomm starts making iPhone LTE radios soon, will need lots of 28-nanometer silicon
One of the features expected to finally arrive on the iPhone with the smartphone's next iteration is LTE connectivity. According to DigiTimes, production of the needed radios is to begin in the very near future. Qualcomm is the manufacturer burdened with the task, the source clarifies. The LTE radios will be made at the TSMC factory using 28-nanometer process, and about 10,000 12-inch wafers will be required. 

Those 10,000 wafers are actually quite a lot – about a third of the foundry's capacity. That is also about as much as NVIDIA will need for its chips, which is bad news for the rest of the companies in need of 28-nanometer wafers. In addition, the TSMC foundry is where Broadcom will be making the Wi-Fi chips, expected to be fitted inside the upcoming new iPhone, which will make meeting the demand for 28-nanometer silicon even more difficult than it already is.

All in all, 28-nanometer chips are likely to be in low supply until TSMC manages to ramp up its production to 50,000 per month, which is expected to happen before the year's end. It is said that over $8 million have been invested in order to make that possible.

So Apple is finally going to try and make a real 4G device instead of just fooling their customers by displaying 4G on their iPhone 4's, which clearly are not 4G devices.

The 4S devices have the same theoretical speeds as 4g ones.

Yes, and theoretically, time travel is possible too, but that doesn't mean it will happen. Besides, even with an LTE radio, the processor in the 4S is behind many of the newer android processors.

theoretically the U.S doesnt have 4G let's start there

I know US 4G doesn't meet the international standard for 4G. The fact remains, many processors in newer Android phones are faster than the one in the 4S. Doesn't matter if it's 3G, HSPA+(3.5G), or 4G LTE. It's just slower.

it has been proven that the processor on the 4S is faster that the SGSII and that was the phone of the year. you can dispute that Androids has true multitasking or that have widgets flash etc... but on paper the 4S won..

"On paper" doesn't really matter does it? Actual performance in use is where things should be determined better or worse. As a sports fan, I'm glad they do not rule winners and losers "on paper". I've put my Rezound next to my gf's iPhone she got a couple months ago, and I don't see anything it does faster than my phone, internet or not.

Gallito, thats not true. They use identical processors. The A5/A5x and the Exynos are the same base CPU chip. The part that is faster is the PowerVR GPU found on the i4s compared to the SGS2's Mali-400. PowerVR is hands down the most powerful GPU series out right now. Im going to get terminology into your head if its the last thing I do :)

@Remixfa, the SGS III's overclocked Mali 400MP4 GPU with (probably) software optimization had already bested the previous king of GPU (PowerVR SGX543MP2).. Just saying.. :)

37. remixfa

Posts: 14605; Member since: Dec 19, 2008

thats quite true. But what do u think the PowerVR would look like overclocked? lol I'd love to find out. clock per clock, the PowerVR is the winner. The mali-400 has been pretty decently impressive, especially with how pliable it has been to overclocking.

What the fact?! Maybe GPU, not CPU.. damn! What's wrong with you.. lol

no, they dont. The 4s goes to either 12 or 14mb/s. 4G LTE and HSPA+ go up to 40-50mb/s and 42mb/s respectively. The only "4g" that slow is sprint, which technically isnt 4g by speed since it only goes to 12mb/s and the minimum 4g speed considered is 14.4mb/s

Well your wrong about the 4G networks, and their real world performance limitations. I think I have to tell you how these "theoretical" speeds are found and why people are going to wait for LTE and not care about the theoretical speeds of t-mobile/at&t... only what they can actually use on a daily basis. The 4s might just be limited to 12-14Mb/s from the network, or it might be limited from the PHONE. (I will also point out that there are other very capable phones out there besides the apple products, but that is personal preference) HSPA+ only can get those speeds by using bonded channels. For those who aren't technical: there are only so many channels that are being broadcasted in a certain area and these channels can only handle a few hundred connections at a time. In a busy city, there are many people on each channel, and this slows the network down usually because of backhaul limitations... so even bonding several together, the speeds are good but nothing amazing. If you are in an area that isn't very populated, there is usually fewer carrier channels anyway, so your speeds are just the normal 3G. Also, I am not sure on the technical specs of Apple products compared to the theoretical speeds, but the apple might only be able to bond fewer channels compared to the theoretical speed test. This would allow it to go faster than 3G, but not up to the theoretical speeds. (more radios=more expensive) LTE is designed to use a much larger chunk of spectrum, but can consistently pull down over 10Mb/s even with the system experiencing heavy usage and not having full bars of signal on a phone. Sprint's WiMax can hit 12Mb/s which I think is good for most users, but suffered from poor implementation from Clearwire. They used only their 2500-2600Mhz spectrum which does not have great in-building penetration, and is hard to blanket an entire city (and not economical for rural use)... the experience was decent as long as you could grab a signal. Sprint's new LTE will eventually cover every site on their network using their PCS and SMR spectrum, so it will function much better and use Clearwire TDD-LTE as volume offloading in cities. Verizon has the most LTE right now, While At&t is lagging them by quite a bit. The only problem is that they are not set up to take advantage of LTE-Advanced (release 10) which will allow aggregation with LTE... This is the real true 4G standard, and Sprint will be the first because all of their equipment that they are installing will only need a software upgrade. After that, they will be able to reach theoretical speeds over 100Mb/s (which is completely unnecessary, but cool) lol. In the next 5-10 years, everyone will probably have an all LTE network that all run at approximately the same speed, and we will just buy data and be able to carry a phone from carrier to carrier. I know that was a long explanation, but I hope that helps you understand.

When has the 4S been able to hit 25 - 30Mbps down, and 6 - 15Mbps up....thats what I average on my RAZR.....and that isnt even the best its capable of. If you wanna compare it to phones hitting the low end of downloads and uploads...maybe. I got between 6-10Mbps down in weak reception areas. It can get 4G like speeds....but I wouldnt go as far as saying it has the same theoretical speeds as 4G. Some phones can hit 40- 50Mbps down.... T Mo didnt even want a certain chip last year because the fastest it could...theoretically...do was 21Mbps down. Carrier skips over a certin chip that still was faster than what the 4S can do....I think only AT&T was that dumb to bend over for Apple.

why not T-Mo has been doing it for years now...

the difference is 42mb/s IS 4g. 12mb/s is not. just because you and your puppetier want to troll doesnt mean you should be factless.. oh wait.. thats how you guys like it best. :)

They have the same "4G" that T Mobile and Sprint are advertising so are you mad at them too? Oh yes just trolling...

Is it me or i just read somewhere that there is a chance that Apple might get sued by Samsung if they use LTE on their upcoming iPhone? lol

Only if it's implemented a certain way. Apple will do it n a way That still allows great battery life though.

I really hope they get sued. Samsung delays the launch of the iPhone and then Apple will finally know how it feels. But then I have doubts. Apple will probably file 20 patents on LTE before the phone comes out.
