ARMed CPUs at 28nm

TSMC is producing 28nm in volume now. With the small size of ARMed chips that is a huge increase in the rate of production of chips and at lower power consumption. At the last level, power consumption was mostly acceptable in every application. Now, power consumption should cease being a consideration. That’s what Intel hopes now that they are doing the same at 22nm but Intel still has power issues because of the wasteful x86 architecture and will have to go to 10 or 14 nm to catch up. Meanwhile, ARM is taking over the world of small cheap computers and is much stronger competition there than AMD ever was (about 20% share of units) on desktop and notebook PCs. Even with 22nm production expected in 2012, Intel will have x86 stuff ranging from 35 to 77watts TDP. Intel’s revenue from Atom has declined precipitously with the shift from netbooks to tablets.

The march of the small cheap computers continues to eat Wintel’s lunch while M$ and Intel try to ignore the swarm. The question is when not whether the picnic will be over.

  1. x86 does not have many times the computing power. The computing power per watt is much higher with ARM. The computing power per gHz is comparable. The computing power per chip is only higher because of the clock speed. You may have noticed that few smart phones have x86 chips. There’s a reason for that, reality.

    Whenever you look at the computing power per something, ARM looks pretty good. The world should look at price/performance for IT instead of throwing money at Wintel.

    And x86 has many many times the computing power. And power is something many many users out there cherish. Actually, everyone who is doing more than browing and skyping. Ops, sorry, Skype now belongs to Microsoft, too.

  3. ARM chips are much smaller than Intel’s. ARM doesn’t need to use finer resolution to do that. Their design uses fewer transistors. x86 over the years has added huge overhead in the silicon which must be clocked at several gigahertz. They use about five times the power to run as an ARM CPU at a similar resolution.

    Actually, Intel’s method of lowering power consumption is to make smaller, and smaller chips, making them 1 step ahead on size. Until we get quantum computing, there isn’t indication that ARM will catch up in size.
