There have been many rumors circulating around about upcoming Apple devices, but not that much has been said about the processor that will be powering these devices. Apple’s A8 Processor, which will power these devices will is said to have a clock speed of 2 GHz or higher.
Apple’s current A7 chip runs at 1.3 GHz – 1.4 GHz. It is said that both the iPhone 6 and iPad Air 2 will feature the new A8 chip and will pass the 2 GHz speed for the first time. It has also been rumored that the iPad Air 2 will run at 2.6 GHz.
The A8 chipset will support 2 cores and a 64-bit architecture, much like the previous A7 chipset. While we see Android devices with many more cores, the extra core support is not noticeable in terms of a mobile phone’s speed. The applications made for these devices do not take advantage of these cores at all. Having extra cores is more a marketing tool at this point.
Apple will be switching from Samsung to TSMC as their foundry partner for the chip. The SoC is said to be based on the 20 nm architecture, which would mean a performance increase and a decrease in power consumption compared to 28 nm chips. Apple is more than likely going to release products based on the A8 chip in the fall.
