TSMC has put a dual-core 32-bit Cortex-A9 processor test chip through the fab dryer and brought it down from 40nm using its latest process (known as 28HPM). The silicon biz was able to crank up the clock speed on the A9 to a comfortable 1.5GHz to 2GHz in a thermal and power-draw band suitable for smartphones and tablets, and pushed the clocks up as high as 3.1GHz for other "high performance" and unnamed uses under "typical conditions" - like perhaps microservers, for instance.
TSMC said that the 28nm part was "twice as fast" as its 40nm sibling "under the same operating conditions", by which we presume it sucked on the same amount of juice and emitted the same amount of heat as a dual-core Cortex-A9 implemented in 40nm and running at 1.5GHz.
