Hardware, Embedded Systems So, we have Intel and AMD. These guys are doing pretty well in laptops, servers, and of course desktops, but when it comes to mobile devices, they've so far been unable to adapt the x86 architecture to the stricter requirements that come with those devices. ARM, on the other hand, pretty much owns this market at this point. And you know what? It's time for Intel and AMD to get worried - really worried. ARM has just announced its Cortex-A15 MPCore chips - which will reach 2.5Ghz in quad-core configurations.

Who cares

about low energy consumption on a high performance desktop PC? Come on. I have a Geforce GTX480 which alone takes how much power? I don't know but it's a lot.

So would I care to replace my Corei7 with an ARM CPU to save a few watts? I don't think so.

Sure it would be a perfect chip for laptops and tablets but not anything near high performance servers and/or desktops.

To talk server side, virtualization already solves the power consumption there.

You've some great points there but I disagree with you're analysis of virtualization solving the power issue server side. Not only will ARM chips use less power than their x86 counterparts, they also now support hardware virtualization extensions giving you even more savings in the power consumption field.

Personally I can see a huge amount of interest in ARM based servers, for the above two reasons alone. If VMWare port their stack to ARM, I can think of quite a few companies that would be very interested in using them for their Linux servers. If not, there is always KVM and/or Xen.

I think that servers would care. It might just save a few watts per chip, but that adds up. A large server with many processors could save hundreds or thousands of dollars a month in electricity.

The computer enthusiast would probably value the low initial cost of the processors. It would be possible to build a computer with mutiple processors that out performs an I7 at lower cost.

Just to clear some stuff up, the electricity you save is not just from the cpu's, but also any CPU that doesn't as much electricity will also not generate a lot heat, which means less cooling is necessary, less cooling also means less electricity used.
