What are the advantages and disadvantages of the different CPU's ? How to choose a CPU ?
Posted on 2006-05-10
I know that there are 5 main CPU's types (also referred as "platforms or "architectures") - x86 (AMD, Intel); Itanium (Intel); PowerPC (IBM); Alpha (HP); SPAC (Sun). Each one has 32-bit and 64-bit versions.
However I cannot understand why and what for, so many CPU's types exist...
x86 has an almost total dominance, since Windows runs on it ("Wintel"), and the best Linux's versions are also for x86, and recently Apple Macintosh also become a x86 system. Why do x86 dominates ? Is it a better CPU when compared with others, or everything is a question of marketing's success ? The computers equipped with other CPUs (different from x86) cost as much as a x86 computer, and there is much lesser availability of Operating Systems and additional applications to run on them. So, who will buy a computer with no x86 CPU ? The price is the same and they offer less software...
I know little about CPU's so this is very confusing to me... I would like somebody to help me to get more knowledge about CPU's... What are the advantages and disadvantages of the different CPU's ? How to choose a CPU ? Please do not forget I am a beginner so you must explain everything... Thanks in advance. Regards.
