You are comparing bananas with watermelons. I met arm architecture from ACORN Archimedes when Intel was on 8086 and 8088. I was very happy because that technology was not destroyed and was with me inside my Mobile phone. Arm will never be a desktop replacement processor as the majority of software is written for Intel processors even in a Mac. The software houses have invested millions on that code that needs to re written. Also arm can not competes I3, I5, or I7 processors. I don't love Intel but is the only company that has trust in business market. I recently bought a chip tablet phone for my wife the Asus fonepad. I was impressed with the performance of that single core atom and with hyper threading and the super low power consumption. In every day use is smooth like my quad core note 8. !!!!!!!
rhere is no competition between x86 to arm. arm is for android(linux); intel is for windows. and arm cpus dont need to scale up to intel level since gpus can do the high performance computing, gpus have been outcomputing cpus in tests since 2008. nvidia has project denver set to 2015, by then they will have arm cpus and gpus for linux notebooks. for phones and tablets, its going to be cortex a12 cpus and intel graphics gpu(powervr). intel cpus consume 10x more power than arm cpus while nvidia gpus use 10x power as imagination tech.
An unequal duel? The times they are a-changin' for the chip industry: x86 in smartphones, ARM in a notebook - what seemed impossible just a few years ago is now a reality. Accordingly, we are comparing different SoCs made by Qualcomm, Nvidia and Mediatek with the x86-based competition from AMD and Intel.
