Processors are becoming far more powerful than we could have anticipated. Comparison of Apple A7 Vs Qualcomm Snapdragon 800 suggest that iPhone 5 is not ready for 64-bit (SoC)

The processors are becoming more and more powerful with every passing day. From 1GHz processor in most smartphones till some two years ago we have far more powerful processors being put in smartphones now.

The technology seems to be improving faster than we ever thought and the change is so fast and so comprehensive that we cannot foresee as to what sort of smartphones we will be carrying in our hands some four or five years from now. From 3 mega pixel camera we jumped to five mega pixel camera that went up to 8 mega pixel camera last year. But now we usually have 13 mega pixel camera in most smartphones. But in some cases –especially in case of camera centric handsets –we have 20 and 21 mega pixel camera.

From 512 MB RAM to 1 GB and then 2GB Ram we seem to have come a long way. And now we have a smartphone (phablet to be precise (with as much as 3GB RAM) in case of Samsung Galaxy Note 3. So the smartphones will become leaner and meaner machines in the coming days.

So the transformation is very comprehensive indeed and the future is going to be very bright indeed. Apple has formally launched its brand new Apple A7 processor by putting it inside its all new handset iPhone 5S. It is a successor to the company’s A6 chipset that features inside the iPhone 5. The new chip has indeed made its debut in the new edition of Apple smartphone, which is about to go for sales across the world. Apple claims that its new chipset is capable to provide two times better performance than its predecessor.  The new Apple mobile processor has Qualcomm’s Snapdragon 800 chipset as its great rival. It has been just a while back that we received the brand new chip form Qualcomm, which is now accepted by a lot of major tech giants including Samsung and Sony for their top products. In other words, nearly all major high-end phones in the world market feature Snapdragon 800-based CPUs. So here we pit the A7 for a comparison with the S800.

Here we take a look its top of the line features that make it stand out in the crowd. The major highlight Apple shows off its A7 chipset for is the thing that it is built under a 64-bit architecture, and thus is the world’s first mobile chipset to go beyond 32-bit architecture. Because of this, Apple claims the chip can provide twice better power, but this theory has been largely refuted by tech analysts. Many specialists claim that 64-bit won’t work with a phone that has system memory less than 4GB. As the Cupertino tech major quickly clarified it the A7 is Apple’s first 64-bit system-on-chip (SoC). It means the apps running in the new iOS 7 will also be 64-bit-based ones, although it is compatible to 32-bit apps, luckily. As per Apple, the new chip can provide 56-times faster performance over the original iPhone, and enhance CPU performance 40-times faster than the first iPhone, and twice faster than A6 of iPhone 5.

But then many have questioned as to whether this handset really has the powerful backing that is required to actually run it. Analysts argue that a handset with 64-bit processor should at least offer 4GB RAM. If not, Apple’s claim that the new chip would bring “64-bit desktop-class architecture to a smartphone for the first time” won’t do justice. Any performance gains the new iPhone 5S has will likely be coming from the enhanced architecture in A7, and not because it has a 64-bit CPU, says Patrick Moorhead, analyst at Moor Insights & Strategy. Apart from this, the new A7 chipset has supercharged graphics powers and it also offers a fresh motion-sensing M7 chip that will boost the graphic power of all iOS devices. The new M7 co-processor can also save battery life and inject stability to the device’s processor performance.

Though the A7 may not have the sort of support that is required, nonetheless future seems to be very bright. In terms of hardware support, the new A7 chipset is basically meant for iDevices like iPhone, iPad and iPad Mini. But, adding 64-bit architecture to the pack, there is a distant chance that Apple may take up the chips for its lineup of PCs, notebooks and more in place of Intel chips.

On the other hand everyone seems to be full of praise for new Qualcomm mobile chip Snapdragon 800. Many say that it is the most powerful to have been launched thus far. The new Qualcomm mobile chip has been introduced with the claim that it could represent a leap forward in performance and energy efficiency. To an extent, the chipset is doing justice to the maker’s claim, because it is reviewed to be providing better performance and energy efficiency. In comparison to A7 chip, Snapdragon 800 is just a 32-bit processor. In regard of processing, the S800 features 28nm HPm quad core Krait 400 processor that is clocked at 2.3GHz per core. Further, it has LP-DDR3 memory for high performance and low latency and Adreno 330 graphics that can deliver up to 50 percent increase in graphics performance. In terms of hardware, it has already appeared in many spotlighted products like Samsung Galaxy S4, Galaxy Note, Sony Xperia Z Ultra and more.
