According to Apple, one of the most important novelties of their new iPhone 5S is the presence of the processor Apple A7, that stand out for their native support of code of 64-bit, Although they not clarified exactly what were the technical benefits that users would gain such ingenuity.
Qualcomm have indicated that this processor is by far more a maneuver of marketing as a significant technical improvement, since It will not offer immediate benefits to its users, and in fact there is no reason for this migration to 64-bit micros.
Anand Chandrasekher, CMO of Qualcomm, said in an interview that “I think that it has been generated much noise environment to what did Apple with the 64-bit on the A7. And I think it is just a marketing gimmick. The benefit that a customer gets those 64-bit is zero”.
Few (or no) current advantage
This Executive indicated that the clearest advantage is to increase the address space and memory that can be integrated into smartphones over 4 GB, but that is not relevant today, and indeed iPhone 5S only integrates 1 GB of RAM.
[64-bit] are needed especially for addresses above 4 GB. That’s it. You don’t need it really to improve performance, and the type of applications that handle is 64-bit spaces are especially large applications to servers.
Although Apple States that the A7 is twice as fast as its predecessor, the benchmarks doubts have been raised on whether the introduction of support for 64-bit code really has impact on the performance.
Qualcomm also bets for the 64-bit, but for the future
Qualcomm is one of the main suppliers mobile processors for smartphones and tablets, and its Snapdragon micros – 800 as its last great exponent – they have demonstrated their ability to conquer this land.
The company has highlighted also will give the jump to 64-bit mobile microproceadores – not indicated date-, but will for reasons pointing to clear advantages in engineering and design of the chips, in addition to the operating systems that support it.
From the point of view of efficiency in engineering the jump already makes sense by itself only. The guys who develop operating systems also will want to jump at some point.
The measure will not respond the need smartphones or tablets of 64-bit, but which will emerge to reduce manufacturing costs. Both Samsung and NVIDIA have already also announced its intention to produce mobile 64-bit micros, by what the market seems to be taking the steps to that future adoption.
Adoption which will not only affect the mobile: in fact, the first 64-bit ARM processors they will be intended for servers as the HP Moonshoot. Companies such as AMD, AppliedMicro and Calxeda are also working on the development of ARM microprocessors on 64-bit servers efficient market-oriented but that does not neglect the power. In Qualcomm also make your bet for this market, but as you pointed out this directive, its focus will continue to maintain in the segment of tablets and smartphones.
