So AnandTech has a Jaguar review up with benchmark data. It has a comparison between a quad-core Jaguar (at 25W) against a dual-core Silvermont (at 10W), and they come in pretty much head-to-head in single-thread benchmarks. Jaguar wins some, Silvermont wins others.
Looks like core-for-core, they're pretty much comparable. And the GPU in the Jaguar SoC is better. So no huge surprises. AMD is competing on price and GPU, while Intel can obviously to some degree coast on brand recognition, and owns the high end.
Sounds like the 90s all over again.
