Leaked: Upcoming HTC Nexus smartphone realease


The new leak comes from ROM developer LlabTooFeR who tweeted out the codenames of the two models. The smaller 5-inch model will be codenamed ‘T50’ while the larger model has been tagged as ‘T55’.

Few days ago, a report from China delivered the first bits of information which stated that HTC would be the manufacturer to build Nexus smartphones for 2016. Once again, we have some news from another source that reveals the same.



The smaller model will replace the LG-made Nexus 5X while the bigger smartphone is expected to replace the Huawei-made Nexus 6P. For now, no other details about these smartphones have been shared. Soon after Google announced the I/O dates, reports about its 2016 Nexus smartphones had surfaced.

The information that had leaked earlier came from a report from China which said that Google is working with HTC to churn out two new Nexus phones this year. Going by the trend among manufacturers, it isn’t surprising to see two variants of the device. Last year, the company had launched LG built Nexus 5X and Huawei built Nexus 6P.

Which chip set is better, MediaTek, Intel Atom or Snapdragon?

1.) Mediatek:

It is a Taiwanese company. It uses more cores in it's processors(like octa core,hexa core,deca core).

Battery Life:

The mediatek chipsets are known to be more power draining and results in less battery life.Now they are optimizing their processors to be more power efficient but still lags behind their competetion in terms of battery life.

Performance:

Performance wise their processors are very good.Due the availability of extra cores,mediatek processors can handle intensive and heavy tasks and they are very good at multi-tasking.But we can see all this practically if we have sufficient Ram.Yes more cores demand more Ram to give best performance.

Heating Problem

Now coming to the heating problem. All the processors deliver heat while performing tasks. Mediatek processors deliver more heat(more cores=more heat) than the others.

Graphics:

Coming to graphics,Mediatek employs Mali graphics which is a third party graphics vendor(So graphics architectue is different from cpu and its performance may not match with cpu). It is really important to match the performances of cpu and gpu(graphics) so that the whole chipset performs efficiently and effectively.

2.)Snapdragon:

Snapdragon chipsets are manufactured by Qualcomm (American) company.

Snapdragon chipsets are not only just CPU's they incorporate other many processors in their chipsets.This is the main difference between Snapdragon and other chipsets.

Snapdragon chipsets are named as SoC's(System on chip) which means their chipsets(SoC's) have a CPU,GPU(Adreno Graphics),Image processor,Media processor,DSP(Digital Signal Processor),Cellular Modem unit,Wifi Modue,Radio Module,GPS Module,...etc. All these modules and Processors are inside of a snapdragon chip.Yes they incorporated all these things inside their chips.Hence their chips are costly.

Battery Life:

Snapdragon chipsets are best in terms of power efficiency compared to all other chipsets.

Performance:

Performance wise they perform really well. In multi-tasking,gaming,handling heavy and intensive tasks they are very good.

Heating Problem:

Snapdragon Processors generally deliver less heat compared to Mediatek and Intel Atom(Except the Snapdragon 810 Chipset-that faced many heating issues.)

Graphics:

Coming to graphics, they manufacture their own graphics called Adreno Graphics and incorporate into their chips. So here the performance of cpu and gpu are matched.

3.)Intel Atom:

Every one is familiar with Intel processors because they are dominant in the PC market. Intel Atom processors are the initiative taken by the company to enter into mobile segment.Intel processors are best in PC's but when it comes to mobile they have faced one problem...!

Battery Life:

Yes, the problem they faced is Battery life. Intel company has experience in manufactuting processors for PC's which consume power in watts(say 40 watts and above) but when it comes to mobile platform where the processors should run on power less than 5 watts, they had a problem in optimizing their processors to work on low power.

Don't worry that is all in the initial stage when they entered into mobile market. But recently in Q3 of 2015 they have announced their Mobile processors called core M-processors for mobile platform like tablets and smartphones. These processors are very power efficient and they consume power of 5 watts and below.But we may only see them in Smartphones or Tablets in 2016.

Performance:

Performance wise, i think i don't need to tell you how Intel Processors do. They are very good both at PC's and on Mobile.

Heating Problem:

Intel Atom Processors also deliver more heat when running heavy and CPU intensive tasks or while using for long duration.Let us see how their core M-Processors perform.

Graphics:

Intel, till now used third party graphic vendors like Power VGR and Mali graphics  in their CPU's. Intel also have their own graphics called Intel Iris Graphics which they introduced in their 4th generation core i-series processors for PC's. I am not sure but i have read somewhere that core M-Processors have Intel Graphics built in. Let us see them in 2016.

Till now, Snapdragon is the clear winner here. I have practically used Smartphones which have all these three processors and telling you my answer.The Smartphones that i have used are Micromax Unite 2 (Mediatek Processor) , HTC Desire X (Snapdragon Processor) , Asus Zenphone C (Intel Atom Processor).

The Difference Between Snapdragon 800 and 801: Clearing up Confusion

A couple of weeks ago at MWC, Qualcomm announced its Snapdragon 801 which was positioned as a speed bump for the next wave of flagship smartphones. Qualcomm touted a 2.5GHz CPU frequency (up from 2.3GHz with Snapdragon 800), as well as increased GPU, ISP and memory interface speeds. Samsung announced immediate support for the new Snapdragon 801 with the Galaxy S 5, as did Sony with the Xperia Z2. Unfortunately this is where confusion set in. The Galaxy S 5 was advertised as a Snapdragon 801 with a 2.5GHz CPU clock, while the Xperia Z2 claimed the same Snapdragon 801 branding but with a 2.3GHz CPU clock - the same frequency as a Snapdragon 800. If it's not CPU frequency that separates a Snapdragon 800 from an 801, what does? The answer, as it turns out, is a little more complex. The table below should help explain it all:
Snapdragon 800/801 Breakdown
 SoC VersionModelMax CPU FrequencyMax GPU FrequencyISPeMMCDSDAMemory IF
MSM8974VVv2S8002.2GHz450MHz320MHz4.5N800MHz
MSM8974AAv2S8002.3GHz450MHz320MHz4.5N800MHz
MSM8974ABv2S8002.3GHz550MHz320MHz4.5N933MHz
MSM8974AAv3S8012.3GHz450MHz320MHz5.0Y800MHz
MSM8974ABv3S8012.3GHz578MHz465MHz5.0Y933MHz
MSM8974ACv3S8012.5GHz578MHz465MHz5.0Y933MHz
The Snapdragon 800 brand applies to an internal Qualcomm model number of MSM8974. The MSM8974 has four Krait 400 CPU cores, an Adreno 330 GPU, dual-ISP, 64-bit wide memory interface and a 9x25 Cat 4 LTE modem. It turns out there are two different silicon revisions of this SoC: version 2 and 3. The Snapdragon 800 v2 silicon was made available in three different flavors: VV, AA and AB. The difference between all three MSM8974 v2 variants was CPU and GPU frequency. This isn't an unusual practice at all as there's bound to be a distribution of operating frequencies for any design. Better bins end up as higher clocked parts, while others get tested and pass at lower frequencies. OEMs can pay more for the faster bins if they want.
In the case of v2 silicon, you could end up with silicon that ran its CPU cores up to 2.2GHz or 2.3GHz. Only the AB variant saw its max GPU frequency climb to 550MHz. The rest of the specs remain identical between all v2 silicon (-AB does get access to faster DRAM). Note that I'm using the marketing frequencies here for CPUs and not the actual frequencies. For whatever reason the OEMs choose to round up to the nearest 100MHz when quoting CPU speeds (2.2GHz is actually 2.15GHz, 2.3GHz is actually 2.26GHz and 2.5GHz is actually 2.45GHz). That's a battle for another day.
Over time it's possible to squeeze more out of a given process and that's exactly what Qualcomm did with MSM8974 v3. This newer silicon revision used improvements on the process side (process push of 28nm HPm) to push frequencies even higher. The options are now 2.3GHz and 2.5GHz on the CPU side. Just like with v2, v3 silicon offers three different variants. Unlike the situation with v2, v3 sees increases in CPU, GPU and ISP operating frequencies depending on which bin an OEM orders. Note that the increases in ISP frequency are substantial. If my math is correct, the Snapdragon 801 should be able to push almost as many pixels through its ISP as the forthcoming 805.
The other major difference is that v3 silicon enables support for eMMC 5.0.
In short, there are two different versions of MSM8974 silicon. Version 3 adds eMMC 5.0 support and hardware dual-sim, dual-active (DS-DA). All variants of v3 silicon can carry the Snapdragon 801 branding, while all v2 variants are Snapdragon 800s.
Putting it in Perspective
What does all of this mean? Let's first talk about the non-frequency related benefits of MSM8974 v3. eMMC 5.0 adds some new features as well as increases the maximum interface speed from 200MB/s in eMMC 4.5 to 400MB/s. As high end smartphones and tablets start using faster internal storage, having eMMC 5.0 support will be necessary to enable faster transfer speeds. SanDisk's recently announced iNAND Extreme update promises 300MB/s sequential read performance for 32GB+ devices. On a smartphone equipped with USB 3 that means you could feasibly copy large movies or files off of your smartphone at up to 300MB/s. Without eMMC 5.0 support you'd be limited to somewhere south of 200MB/s.
DSDA support matters to specific regions, and for those areas the benefit is obvious.
Supporting faster LPDDR3 means more available memory bandwidth for all of the big consumers on the SoC. I'd expect improvements in high end 3D gaming performance, and potentially certain camera/imaging workloads. Remember that all parts of the SoC have to share that tiny interface to main memory, so more memory bandwidth definitely doesn't hurt.
On the frequency side, the gains are pretty easy to understand. The higher peak CPU speed will translate into faster web page and application loads. Higher GPU frequency will allow for smoother frame rates in 3D games, and the faster ISP frequency can enable quicker processing of camera sensor output. You can also look at the benefits of these things from the perspective of lowering power consumption. Tasks can now complete in less time, allowing these individual IP blocks to quickly move down to lower power states and increase battery life.

Comparing Mobile Wallets From Apple, Google and Samsung

In the last two years, Apple, Samsung Electronics and Google have released mobile wallets. To combat fraud, merchants have also been moving away from accepting credit card payments with the magnetic stripe and instead are requiring chip cards.

We decided to test how well these new technologies work. We found that mobile wallets were more convenient than chip cards. While all the mobile wallets generally work the same, they each have pros and cons. Here is a rundown of how the mobile wallets compare and where they are accepted.


Samsung Pay

HOW IT WORKS: Download the Android Pay app from Google’s Play Store and set up the wallet with your credit card. Tap the phone on the terminal to pay.

What the Apple Watch Does, One Year Later

A YEAR ago this month, Apple made its Apple Watch available for sale. In the 12 months since, the smartwatch has received mixed reviews, and many people are still uncertain about what the device can do.

The Apple Watch’s uses, of course, partly depend on the apps available for it. On that front, the news is good — the list of apps for the watch is ever-growing. Here are some of the best ones to try.


The Buy Me A Pie shopping list app lets you share information to simplify shopping.
My favorite Apple Watch app is one of the simplest. It’s called Facer, and it does one thing: It puts a different background image on the screen of your watch every time you raise it to see the time. This is weirdly rewarding. I love glancing down to see a new or interesting image when checking the watch, and it reminds me that this device really is a piece of 21st-century technology.

There are a few limitations to Facer. The biggest is that you are stuck with only one watch face design  the simplest, which shows only an image and the time. That means you will not see features like alerts or weather information that you can see on other watch faces. You also have to pay for some of the images, which can cost $1 and up.

The most useful watch app I have installed is Grocery Shopping List Free — Buy Me a Pie!, which works on both the watch and iPhone.

The idea is that when you survey your shelves and refrigerator, you use the iPhone app to pull together a shopping list. The app makes this easy, offering prearranged options for items you may regularly buy, like bread, milk, bagels and so on. You can color-code each item to make identifying different categories of products easy, and items the app does not already have can be typed in. You can also set up multiple lists, and share them with others.

When shopping, you can view your shopping list on your watch, without having to fish out your phone. This is a fabulous memory aid. Swiping the items on the watch screen to mark them as bought is satisfying. And you can use dictation on the watch to add items to a list, which is great when you suddenly remember something you need to buy.

Promoting health and fitness is a great use for the watch, and the $3 HeartWatch is particularly helpful. The app shows your most recent heart rate reading, as well as an indication of your average heart rate and the maximum and minimum for that day.

At a glance this can tell you if your heart has been speeding, which is useful after a jog, for example. By using Force Touch — pressing hard on the watch — you can add a note to that day’s readings, or add a measurement to your Apple Health app, including weight, body temperature and many more.

The accompanying iPhone app is well designed and can display lots of heart health statistics, most of which are easily readable thanks to clever graphics. You can also use it to track your sleeping habits

A better sleep tracking option, though, is the free Sleep++. This works by measuring your movements during the night via your Apple Watch, giving an indication of how restless you were.

The app has one button to turn the sleep-detecting mode on, during which it displays your bedtime and how long you have been sleeping. There is also a single button to turn the sleep mode off, after which the app shows some sleep statistics. The accompanying iPhone app displays detailed information about sleep patterns.

The one downside of this app is that the watch must be worn during the night, which may be uncomfortable for some.

Cycles is another useful free health app, delivering at-a-glance information about a menstrual cycle. Its accompanying iPhone app lets people log many more details and set up alerts.

Final mentions go to the eye-pleasing weather app Weather Underground, which I prefer to Apple’s own weather option; Meetup, a great location-based watch app that is good for meeting like-minded people for work or for shared pastimes; and Glyphica, a text-based adventure like so many classic adventure games that you can actually play on your watch. These are all free.

Apps to Build Your Understanding of the Environment

EARTH DAY, which takes place on Friday, has become an increasingly well-known event as politicians, billionaires and others take part in building awareness about the environment. You, too, can participate in Earth Day with apps that remind you how to add a touch of green to your life.

GoodGuide is particularly helpful in that regard. The idea behind the app is that instead of being a slave to advertising while shopping, people can make informed choices. GoodGuide has a database of more than 200,000 products sold in the United States, including food and skin care products. It details how much particular goods affect the environment and your health, and whether the products are energy-efficient.

The GoodGuide app has a database of more than 200,000 products and includes details on how those products affect the environment and your health.

GoodGuide’s clear graphics and simple interface make it easy to search for a particular product. There is even a built-in bar code scanner to find data on various items, which can be handy in a supermarket. The app is free on iOS and Android.

It’s sometimes easy to forget that we share our planet with other animals, many of whom are threatened by humankind’s changes to their habitats and lives. This is something the World Wildlife Fund’s WWF Together can tell you about.

Using photos, animations and interactive graphics, the app lays out the stories of endangered animals around the globe. The beautiful images speak for themselves in many cases, but the program also has plenty of data — for example, it points out that efforts to protect the endangered giant panda in China have helped increase the number of wild pandas over the last decade. WWF Together also has 360-degree photos of habitats, as well as educational games.
