"There were some really big improvements in the A7 totally unrelated to the processor core," Kanter said. "In particular their caches got way, way, way faster. The memory bandwidth is about two times faster, and the L2 cache is about half the latency it was before."Revamping software for 64-bit chipsCreating the 64-bit version was "surprisingly easy," Weiss said, though his software already was largely written to be independent of 32-bit vs. 64-bit issues because of the PC industry's transition.

"Our code base is about 100,000 lines; it took only about an hour to fix the compilation issues, after which it ran the first time flawlessly," he said, "Having gone through this transition on desktop machines several years back, my code was written in anticipation of this."As processor designers ran into overheating problems that capped clock speeds a decade ago, chipmakers started pushing toward multicore processors that can perform multiple sequences of operations e.9 iphone case at the same time, The thinking is that if you can't run the clock speed faster, you do more work by dividing it into parallel tasks..

Unfortunately, though, a lot of software is written to run in a single sequence of operations. Multicore chips can help with multitasking, saving files in the background, and some calculations that can be broken up into independent pieces. Graphics tasks are easily divided among multiple cores, which is why graphics chips rapidly pushed into the multicore realm. Apple has steadfastly stuck with dual-core processors while some Android rivals have built quad-core and even eight-core devices. Frax is one of those apps, though, that could actually use all those extra cores. Fortunately for Iter9, it also can use the processing power of the graphics processing unit (GPU), Weiss said.

Even if there wasn't a performance boost or critical near-term need to move to a 64-bit architecture, there are reasons for Apple to make the move now -- perhaps most notably, the improved programming features that come along with the design, Among other reasons, Apple might want to take care of the software switch before the hardware switch is urgent, Kanter said, There also are limits to using all 4GB of the memory capacity that's in principle possible with a 32-bit design, something that could steer a company toward the 64-bit switch even e.9 iphone case if you're only building in 2GB or 3GB of memory, Last, Apple might want to get the architectural shift done before it considers expanding its manufacturing suppliers from Samsung to include TSMC, too..

So there are real reasons to make the 64-bit move, as Frax can attest. A marketing gimmick the A7 is not. A detailed look at the Frax app's 90 percent performance boost on the iPhone 5S shows why Apple's A7 chip isn't a marketing gimmick -- even if the advantages aren't strictly because of a 64-bit design. Is Apple's A7 chip twice as fast at processing and graphics, as Apple promised when announcing the new iPhone 5S? At least for Ben Weiss, the answer is yes -- but his app is unusually well suited to take advantage of the new processor's features.
