手机cpu（Mobile phone CPU） Android Android system CPU performance comparison analysis, Milestone milestone really so God? Performance comparison of mobile phone CPU! The basic knowledge of high-end mobile phone CPU is universal! CPU decides high-end and low-end mobile phones? Where exactly is the gap? At present, the market for high-end Android mobile phones using several major categories of CPU and nothing more than: Samsungs S5PC110 (hereinafter referred to as C110), Tis OMAP 3430 (36X0), Qualcomms Snapdragon 8X50 (MSM 7230/MSM 8225). In view of the fact that N mice always thought Milestone using the OMAP 3430 performance is always invincible, this is really the seckill seckill, which is necessary for the basic theoretical knowledge popularization. Ti OMAP 3430 (L1 64KB, L2 256KB, DDR 256M) is the industrys first use of ARM7 instruction set (ARM7 instruction set) CPU, Ti Cortex A8 (call it Ti completely using the framework provided by ARM company, is not modified, so the launch of the product is very fast, because it is the first) the new framework of CPU, so the performance than the original ARM 11 framework U to improve a lot, generally considered the frequency performance of ARM 7 is ARM 11 200% (by the way of NOKIAs flagship machine is still in use about 600M ARM 11 framework rotten U said weakness, also in the early HTC G1, G2, G3 use the ARM 11 framework CPU). It is because of the OMAP 3430 launch time early, so far, has to keep up with the mainstream, ask to use Milestone s shoes in the upgrade to Android 2.2 after playing Flash problems will know, and we dont 256M RAM can be upgraded, the highest CPU supports 256M, Moto is not stingy no, you had to 512M RAM. The difference between OMAP 36X0 (support 512M DDR2) and OMAP 3430 is that the former adopts the 45NM process, and the latter uses the 65NM process, and the two frameworks are Cortex A8, and there is no difference between them. The advantages of the advanced process are higher frequency and less power con
