Apple was accused of employing a marketing gimmick recently when it announced a new 64-bit processing core for the A7 ARM chip, which powers the new iPhone 5S. The benefits of moving to 64-bit processing on mobile devices aren’t yet clear, but that hasn’t stopped other ARM chip makers from lining up to mention their own 64-bit plans. Nvidia announced several years ago that it had licensed ARMv8 technology to build its own custom 64-bit core, and the time draws near when that endeavor will come to fruition. Tegra could finally be ahead of the pack.
