以前,作为系统心脏的CPU是电脑中最容易选择的东西,周围全是“Intelinside”,但随着许多厂商进入芯片市场,作购机决定已变得越来越困难了,升级时需要讨论的不仅有价格,而且还有升级潜力。尽管CPU发展图每天都在改变着,但经过我们的精挑细选,还是能获得一个满意产品的。下面我们就CPU的架构、价格、性能等方面分别加以阐述。1、架构:这是需要讨论的首要问题,你喜欢哪个平台呢?当前市场占有率最高的分别是英特尔的X86,DEC的Alpha和摩托罗拉的PowerPC（苹果）。价廉物美的X86是最流行的平台,远远超过了其它二种产品,所获得的软件支持也最多,缺点是浮点运算和总线吞吐量不足。虽然它是理想的家庭PC,但随着Xeon的推出也慢慢有能力和Sun,SGI,DEC竞争高端市场;AlPha控制的是高端处理,它可以运行WindowsNT,因此也拥有较多软件,缺点是价格昂贵;市场图形/视频编辑和桌面出版上的大哥则是PowerPC（苹果）,缺点是支持它的软件非常少。
In the past, the CPU as the heart of the system was the easiest choice in the computer, surrounded by “Intelinside,” but with many vendors entering the chip market, the decision to purchase has become more and more difficult and needs to be addressed when upgrading Not only the price, but also upgrade potential. Although the CPU chart changes every day, but through our careful selection, or to get a satisfactory product. Below we will CPU architecture, price, performance, etc. were elaborated. 1, architecture: This is the first question to discuss, which platform do you like? The current market share is the highest of Intel’s X86, DEC’s Alpha and Motorola’s PowerPC (Apple). The most cost-effective X86 is the most popular platform, far surpassing the other two products and receiving the most software support. The downside is the lack of floating point and bus throughput. Although it is the ideal home PC, it has also been able to compete with the likes of Sun, SGI and DEC as Xeon debuted; AlPha dominated high-end processing, which runs Windows NT and therefore has more software, with the drawback of Expensive; big brother on the market graphics / video editing and desktop publishing is PowerPC (Apple), the disadvantage is that support for it’s software is very small.
