14 DAY TRIAL // KGI Securities analyst Ming-Chi Kuo believes the iPhone 5S will be powered by a faster A7 SoC that uses more advanced RAM and a smaller overall set of hardware packages, which will result in around 20% more performance.
Kuo’s latest research note reveals that Apple's next-in-line A-series chip will be based on the ARMv8 architecture with tweaked hardware and software packages that will allow the company to up the processing ante by 20 percent (in comparison with the A6).
Kuo expects the A7 chip to carry the same amount of on-die RAM (1GB) but via a faster specification - LPDDR3 RAM.
According to AppleInsider, “The increased bandwidth will allow Apple to maintain a relatively small amount of dedicated memory.”
Finally, Kuo believes it is not impossible for Apple to make the jump to 64-bit processes this year. However, the safest bet for a 64-bit A-series chip is the A8, which is likely to come out next year (in the iPhone 6), Kuo says.
