I still don't get the hype surrounding ARM.,(reply>), @inode dentry but pretty much every mainstream implementation has resulted in severely underperforming devices. One can even argue that the modern generation of x86 are extremely power efficient as well by comparison to older generations. <br><br>Aside from the licensing thing, I still don't see how it can be seen as a better option. Unless there's a huge leap in the technology, really don't see it ever appearing in servers. I for one wouldn't trade an improvement in battery life for a computer that runs way slower by comparison to the tried and true.<br><br>Perhaps things will change, but right now there's more hype than it deserves. Just don't see it being a real competitor until it can match processing capabilities at the promised lower power consumption.,(reply>), ARM CPUs are extremely power-efficient (meaning no need for beefy cooling or big batteries) while delivering fairly good (albeit not top-notch (yet?)) performance, and can be licensed to many different companies to design, manufacture and improve (unlike x86 where only Intel and AMD can make compatible CPUs due to IP laws/restrictions).<br>It's great! We can have laptops with insane battery life, we can have greener servers/datacenters that have a fraction of the electricity usage, and we can have many brands of CPUs competing to make better products.<br>The downside is that it is incompatible with the current Windows/Mac software ecosystem that is based on x86, but that's changing.
