  • Intel teaches Haswell the core values of teamwork, optimism

    Sure you can make wild, individualistic boasts about having a 22nm fabrication process and three different GPUs, but that stuff counts for nothing without the magic of cooperation. The Amish know that and so does Intel, which is why its forthcoming Haswell cores will support Transactional Synchronization Extensions (TSX) -- a new instruction set designed to allow cores to work together more closely without hammering each others' fingers. TSX takes greater responsibility for the division of labor between cores at the hardware level, relieving the software programmer of some of this burdensome duty and hopefully allowing for finer-grained threading as a result. The system also relies on inherent optimism, with each core assuming that the others have handled their part of the work successfully. Inevitably, there'll be occasions when this happy belief gets splintered and a bad job has to be started again from scratch, but on average things should get done quicker and leave more energy for the barn dance.

  • ARM-based processors to overtake x86 competition in netbooks and MIDs by 2013?

    We suppose industry analysts must be paid on account of just how grand their prognostications are. ABI Research know-it-alls have come out with their own spectacular claim today by asserting their expectation that x86 processors -- still dominant the world over -- will be swept aside in the rapidly developing "ultra-mobile device" space by the ascension of ARM-based processing architectures. That the Cortex CPUs have grown in popularity (and power) is undeniable, but who realistically expects Intel to sit back and watch all this happen? The x86 patriarch has even gone and created an Atom SDK, so we hardly expect the forecast table above to become reality. We're just happy to see that ARM's lower power profile is attracting investment -- it's always good to see a threat to Santa Clara's chokehold on the CPU market, and AMD's sleepwalking through the past few months hasn't helped things. Now if only those Tegra 2 smartbooks were on retail shelves instead of inside prototype shells, we could get started on this supposed revolution.
