Smarter Systems…Balanced ApproachCPUs -- High-performance / low-power CPUs are critical; you don’t need high-end level PC processor performance
GPUs -- Critical and are more important for the success of these devices then the CPU. A good GPU can make or break the device.
Video – It is about HD, you can’t do it, you can’t play. Encode as well as decode. Now 3D
Tuned System – Only use what you need when you need it. New measurement is days of use vs. GHz
Secure Processing – Delivering secure devices, secure content, secure services, secure payments…securing your digital world
