Mediatek announced a 64-bit LTE chip
At the MWC 2014 exhibition which has already ended, Taiwanese company Mediatek, a major manufacturer of low-cost SoC phones, presented two new products for phones - MT6752 and MT6732, and a combined wireless chip MT6630
MT6732 and MT6752
Both chips are based on the new Cortex A53 architecture with the ARMv8 core.
MT6732 is 4 cores, frequency up to 1.5 GHz, and camera support up to 13 Mp. The older version of the MT6752 already has 8 cores with a frequency of up to 2 GHz and support for cameras up to 16 Mp.
The remaining parameters of the chips are identical:
Chips will appear on the market in the third quarter of this year. Since, by their good tradition, pin-to-pin is compatible with previous versions, by the end of the year, phones based on them will most likely appear on the market.
But with the support of the 64-bit mode, for the time being everything is not so simple - the main operating system for these chips, Android is still completely 32-bit.

MediaTek MT6630
MT6630 is a solution to support all common radio protocols in a single chip. Its features:
The chip itself will be available in 5x5mm WLCSP (BGA) and 7x7mm QFN packages.
Pump express
Separately, it should be said about the pump Express Pump Express
This is a technology with which the charge controller can “talk” with the power supply, interrogating it for the maximum current it can give. This will allow the battery controller in the phone to use the resources of the charger to the maximum, reducing the charging time. In fact, this is the replacement of resistors on medium contacts in Apple devices.
For high-power devices, there is also Pump Express Plus, which, after talking with the phone, will be able to raise the voltage to 12 volts.
The technology is present in all the above chips, but its actual use will most likely begin no earlier than the second or third quarter of 2015.

The remaining parameters of the chips are identical:
- 40-bit memory addressing, which makes it possible to use up to 1 TB of address space (as I understand it, only in 64-bit mode)
- Set of 64-bit AArch64 instructions, backward compatible with AArch32
- Mali-T760 as a GPU
- LTE support (no information about bands yet) 4 categories (150Mb / s DL)
- H.265 Iron Decode
