Intel’s not the only processor manufacturer on the block switching from 65nm to 45nm technology this month. AMD held a press event today to let us know that, yes, it too would adopt the 45nm process for its new procs.
This makes for lower-power and cooler-running processors, and speed is improved as well.
The smaller the “pitch” between the transistors on the chips is, the faster, cooler, and cheaper (power-wise) they run, and 45nm was the next logical progression for AMD to take.
