core iPhone is faster than 8 There is something strange going on in the world of smartphones.
Just two cores in the iPhone 6! Sounds implausible for one of the most expensive phones in the world when something like the Xiaomi RedMi Note, which sells for less than Rs 10,000, rocks a 4 core processor. Is Apple ripping off consumers? Is iOS, which powers the iPhone 6, is so easy on resources that it can be easily powered with a dual core processor while Android KitKat or Android Lollipop needs a quad core processor? The answer to both questions is no. The truth is that the dual core processor in the iPhone 6 is the world's fastest mobile processor. Yes, you read that right. The A8 processor, which has two cores and runs at 1.4 GHz, in the iPhone 6 is faster than the Qualcomm Snapdragon 805, which is the fastest smartphone processor available to Android phones, even when the Snapdragon 805 has four cores and runs at a speed of up to 2.7GHz. The reason why Apple's dual core processor beats all the four and eight core processors is because Apple has made the right choices (and right compromises) in designing its processors while in the world of Android, companies are just chasing after the core count. To understand this keep the following in mind: The processing power of a chip depends on a lot of factor. Core count and the speed are just two aspects of it. More important aspects when it comes computing performance is memory bandwidth, latency and ability to execute threads in a more efficient way. This governs the instructions per cycle (IPC) that a processor can push put. IPC depends on many aspects but it is not a given that high clock speed or more number of cores leads to better IPC. Keeping this in mind, here is what is happening in the mobile world. Apple, which started designing its own processors with A5 in 2011 probably because it felt no other company was taking the right approach, is going after the IPC. Now IPC is something that sounds bad on a marketing brochure. The number of core sounds more sexier. So other companies like buy burberry cape Qualcomm and MediaTek are focussed on increasing the number of cores even though it doesn't matter. So how is Apple making its processors faster even though they have just two (or in the case of A8X in the iPad Air 2, three) cores? burberry livermore Here is how Scott Wasson, the technology guru at the TechReport explains it : While many of its competitors have taken the path of increasing core counts in their latest SoCs, Apple has built one of the highest throughput mobile CPU cores anywhere. We know even from big desktop PCs that the user experience is often dominated by the performance of one big, hairy thread that's difficult to execute. Apple's decision to pursue higher per thread performance instead of expanding the core count seems like the smart course. In simple words, Apple is building its processors with a wider and more complex pipeline that also has a great deal of focus on maximising memory bandwidth. It is not easy to build processors like these. Processors with longer and simpler pipeline are easier. The longer pipeline also helps companies clock processors high, so they can tell consumers that their processor runs at 3GHz. But Apple's approach is to build a processor that is more efficient. This means its latest processor A8 not only gives better performance with just two cores but also consumes less energy, which means better battery life. So, how fast is the dual core A8 in the iPhone 6 compared to the quad core Snapdragon 805 in the Galaxy Note 4 and the 8 core Snapdragon 615 in the HTC Desire 820. Here are some numbers from GeekBench. The quad core Snapdragon 805 burberry brit dress is faster in multi core benchmark but that doesn't matter in real life because most of the apps can't properly make use of multiple cores. When it comes to computing what stores sell burberry performance there is a saying that there is no substitute for good single thread performance and that is where the iPhone 6 is so much faster compared to other devices. We saw this earlier in 2006. When Intel and AMD were racing against each other and AMD started gaining an upper hand due to its better processors in 2002 and 2003, Intel decided to counter by increasing the speed of its processors. But even as Pentiums ran at a speed faster than 3GHz, they mostly lost to AMD processors in terms of performance because the IPC was low. Intel changed this in 2006. It came out with Core processors. The first mainstream processor using the new technology E6300 was so good that it beat the most powerful and expensive Pentium processors silly even when it was running at 1.9GHz while the Pentium ran at a speed of over 3GHz. Something similar is happening in the world of mobile processor. In terms of their underlying technology, in many ways the processors used by the Android phones resemble the power hungry and inefficient Pentiums while the processors created by Apple are more efficient. No wonder the Apple A8 beats the quad core and octa core processors even though it has two cores running at just 1.4Ghz.
Best of all, it also helps Apple provide better battery life in its phones. The only way this situation is going to change is if companies that make processors for Android phones start improving the core technology inside the chips or in other words improve the CPU architecture. Or else Apple will continue to hold the processing lead.
