SAN FRANCISCO – ARM announced a new processor core, GPU core, and interconnect targeted for mobile SoCs. The 64-bit Cortex-A72 processor core, Mali-T880 graphics core, and CoreLink CCI-500 aim to power a new class of mobile devices that “serve as your primary and only compute platform.”

While slim on specs, ARM promises that its Cortex-A72 processor will deliver 3.5 times the performance of its Cortex-A15 devices while consuming 75% less power. ARM says its Mali-T880 graphics cores are similarly impressive in generation-over-generation improvements supporting resolutions up to 4K pixels at 120 frames/second.

The new version of the cache coherent CoreLink provides twice the memory bandwidth and 30% more performance as a processor/memory interconnect than ARM's earlier version. It also supports ARM's TrustZone for secure decoding of video from a Mali core.
