Hello! I ask this just, because I'm curious:
When Intel is saying e.g., their processor is running at 3000MHz, what does this mean? Is there really any digital signal inside at that frequency, and a PLL that locks it to the in/out frequencies? I know, if they say, there front side bus operates at 800MHz, it's only 200MHz. Then they just multiply it by 4, because it's 32bit. But I cannot compare anything to vintage 8bit processors, so that doesn't make much sense. The second thing is: Processors are advanced thechnology. But could it be possible to have these speeds for a digital circuit, which means, a transition frequency of >10GHz to remain any waveform other than a pure sine? If I try to make a circuit with a simple 1stage transistor amplifier, I'll use the most expensive III-V-HEMFET for 10GHz, and it's still a challenging task, and power below 10W; and they can do this with >100 000 000 silicon tansistors, 100W of power, on a single chip for $250? I ever tried to wind a wire loop around a running procesor and connect it to a spectrum analyzer. But you can see anything from nearly dc up to the max freq. of the analyzer. No strong peak at the declared frequency. Thanks for your answers!
