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.

Intel and AMD should be worried, because a relatively small company without their own manufacturing capabilities announces their first high-performance design, due out in 3 years?

ARM has an uphill battle as far technology goes.

They only have 32-bit chips, so addressing more than 4GB requires PAE-type extensions, with an associated loss in performance.

Putting multiple chips on a board is quite different than putting multiple cores on a single chip. You can't used shared caches, which will greatly enhance the importance of a good cache-coherency setup, and the interconnects are much slower.

Including virtualization, I think, is a waste of die space, thus a waste of power. This chip seems well suited to the "physicalization" trend, where instead of heavy-duty systems running multiple smaller virtual machines, you rely on many small machines to run small tasks. Apparently, this is the way to go if you are running many, many light-weight tasks. Virtualization hardware also isn't something that can be shut off when not in use, like you would an ALU or FPU.

This chip sounds cool, and while I doubt it really will make much headway into server or laptop markets, it'll definitely serve to keep Intel out of phone/handheld markets, at least for a few more years.

Agreed, this ends up being more a stop gap processor with a short life before a real 64bit one comes out.

To get into the future tablet/netbook market and more importantly the low power server market they really need that 64bit...

Not only that, but there have been multicore core low power MIPS parts, even with 64bit versions of the architecture... and none of them have made to the commodity market.

The markets that may end up adopting these sort of ARM parts are not the ones most of the posters in this thread think of.

It makes sense, when all you know how to use is a hammer... every application looks like a nail to you. So most people here know computing at the personal user lever, so every processor looks like it is supposed to go into their assembled together white box system in their parent's basement.
