One of the selling point of any smartphone these days is its processing power. In this mobile industry a war has begun for brining out the most powerful and energy-efficient processors. Based on 32-bit ARM Cortex-A7, A8 and A9 we’ve seen many processors from single-core to octa- core combinations. But now its time to move to the newer 64-bit architecture. After the launch of Apple iPhone 5s with a 64-bit processor based on new ARM v8 architecture, people are demanding for the same to other mobile manufacturers. Recently mobile processor manufacturers like Qualcomm and MediaTek have announced their 64-bit processors at MWC. Lets have a look at them.
Qualcomm has announced three processors during MWC in which two of them; the Snapdragon 610 and 615 are 64-bit processors where as Snapdragon 801 is a 32 bit processor.
Qualcomm Snapdragon 610 and 615
The Qualcomm Snapdragon 610 contains four Cortex-A53 cores which are 64-bit and ARM v8 based. The Snapdragon 615 is the same as the Snapdragon 610 but with four extra cores of same kind which makes it the first octa-core processor from Qualcomm. Both processors have the new generation Adreno 405 GPU, you also get LTE connectivity and Wi-Fi ac/a/b/g/n standards. Both of these processors are targeted for mid-range smartphones and will arrive in the market sometime in Q4 2014.
Qualcomm Snapdragon 801
The 801 is a renewed version or you can call ‘an over-clocked version of Snapdragon 800′ which is used in many high-end smartphones of 2013. There’s nothing new in this SoC except that the CPU clock has been increased from 2.26GHz to 2.45GHz and GPU clock has been bumped from 450MHz to 578MHz. Unlike the previous over-clocked versions, this time Qualcomm has also increased the memory bus from 800 to 933MHz. Immediately after the announcement of processor, Sony and Samsung have unveiled Xperia Z2 and Galaxy S5 which are powered by this 801 processor. We are yet to see the Snapdragon 805 which had some interesting features. There is no word from company about the high-end 64-bit processor yet.
MediaTek MT6732 and MT6752
Just a day before MWC, MediaTek has announced MT6732 which is a 64-bit chipset. The SoC is equipped with a quad-core ARM Cortex-A53 CPU clocked at 1.5GHz coupled with the next generation Mali-T760 GPU which supports Open GL ES 3.0 and Open CL 1.2 for high-end graphics. It will be capable of playing full HD videos and 13MP image processing. On the connectivity side it will feature category 4 LTE, Bluetooth 4.0, Dual band Wi-Fi and Miracast. The chipset will be available by Q3 of this year. Like the Snapdragon 610 and 615, MediaTek MT6752 and MT6732 are identical except that the MT6752 is over clocked version with eight cores instead of four cores and is clocked at 2.0GHz rather than 1.5GHz. Both the processors are targeted on high performance”Super-Mid” market according to MediaTek and will strongly compete with Snapdragon 610 and 615.
MediaTek MT6630 Wireless SoC
This is the world’s first five-in-one combo wireless SoC. The MT6630 supports dual band-band Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 4.1,Tri-band GPS reception and GLONASS, FM transceiver and in addition to all this it also features the advanced Wi-Fi Direct and Mediatek’s MiraVision. The company has also managed to overcome the slow charging process with Pump Express fast charging technology which will reduce battery charging time to almost 50 percent. The devices featuring this chipset will be out in Q2 2014.
This is the second generation flagship of the company based on ARM’s big.Little architecture. The predecessor used the eight ARM Cortex-A7 cores. The new chipset offers a combination of four ARM Cortex-A7 cores clocked at 1.7GHz and four ARM Cortex-A17 cores clocked at 2.2GHz. The new Cortex-A17 cores provide 60 percent performance boost over the Cortex-A9 while consuming less energy than the predecessor. Unlike Samsung’s Exynos all the eight cores can be run simultaneously on any configuration according to the demand, thanks to MediaTek’s own CorePilot Heterogeneous Multi-Processing (HMP) which enabled this.
The current generation MT6589 which uses PowerVR SGX 5xx series suffers from low graphics performance on full HD displays which is also a main point why manufacturers like Sony and LG haven’t used one of these but the new MT6595 uses the PowerVR Rougue series 6 which will be a big improvement in the graphics department and will enable smooth performance and gaming on full HD displays.
The chipset will also fulfil all the coonectivity demands with 4G LTE, Wi-Fi 802.11ac, Low-Poer Bluetooth, GPS and GLONASS. Finally company has invented an alternative to Qi Wireless charging called as “Multimode” and it supports Qi devices along with other standards. There is no word on availability of the chipset yet.
