The arrival of 64-bit midrange smartphones is highly anticipated. It will be an important moment for the smartphone market.

Personally, I think 32 bits is enough for any application I'd care to run.  If you need more than a few GB of memory, IMO the application is being ridiculously wasteful.  But YMMV -- if some people think it's fun to debug 16-digit hexadecimal numbers, I'll quote Mr. Knightly: "I have nothing to say against it, but that they shall not choose pleasures for me."

IMO 64 bits is for mainframe operating systems.  For my personal use, I prefer something... well, more personal.

JMO/YMMV

32/64 bit transition

Do you agree with ARM that the high end handset is 64-bit this year and the midrange stays 32-bit at least through 2015?

Ah I see:

"MediaTek today announces the MT6595, a premium mobile solution with the world's first 4G LTE octa-core smartphone SOC powered by the latest Cortex-A17™ CPUs from ARM."

4xA17 + 4xA7 in big.little arrnagement with Rel. 9, Category 4 FDD and TDD LTE with data rates up to 150Mbits/s downlink and 50Mbits/s uplink.

AND
  • Multi-standard inductive and resonant wireless charging functionality available
  • Supported by MediaTek's companion multimode wireless power receiver IC

Interesting

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
