Re: I have a simple plan...
"2. Treble the clock speeds."
Intel called. They want their P4 NetBurst CPUs back. If you'll look back, you soon realize you can't just run everything faster. It just doesn't scale. Why do you think CPUs weren't and even today aren't specced much higher than 4GHz in clock speeds? One word: HEAT! The problems Intel had with NetBurst were the reason they had to take a step back to the P3, work smarter instead, and the end result is their current CPU line, the Core series.
"3. Make much faster memory."
There isn't much you can do about faster memory anymore without side effects. The biggest obstacles at this point are the speed of electricity combined with cycle lengths. In one nanosecond, electricity can travel, at most, about a foot. And yet you need at least some spacing due to all the heat both the CPU and the RAM inevitably kick up.
