Robert Helenius means, based on the above diagrams and line of reasoning, that in this case some other aspect than processor performance, heat generation and component cost has to decide if to choose an ARM processor or an X86 ditto. He has a suggestion.
- Make the choice between ARM and X86 based on the preferred eco system of hardware and software, the eco system that matches the application requirements and your vertical market, he says.
Traditionally ARM processors have successfully been used in battery powered and handheld units. X86 processor alternatives have occupied the market segments requiring powerful processors. Nowadays more ARM processors with increased performance and higher clock frequencies are released. At the same time X86 processors targeting compact and battery operated applications and X86 options adapted for particular vertical markets are released.
ARM and X86 processors are head to head competitors in more and more performance segments and for an increasing number of applications. There are of course differences in the amount of and type of I/O provided by individual CPUs but that is a different story.
Hectronic develops embedded computers based on both ARM and X86 processors. We have vast hands on experiences in pros and cons for the ARM and X86 architecture respectively. We look forward to the discussion and considerations leading to the decision on which architecture of the two to choose to best match the requirements of your application.
