#3> But there are also strong concerns that the increased frequency will raise the CPU temperature so much that it will cause an actual physical melt down. Note that many CPU manufactures will not allow a meltdown to happen

#4It's there if you want it, but liquid helium doesn't come cheap.

#5"Only you can prevent overclocking fires!"
Nicely written. Seems like the intended headline was "why it's bad to overclock", though!

At least they have a sense of humor.
Edit: Oh, 2014. The sweet irony.

#7Seems like an incredibly long winded way of saying 'To go faster you either need to split up each instruction into lots of parts or increase the voltage for the transisters. We've split the instructions as much as we can, and power consumption is proportional to Voltage cubed, so it's not a scalable plan.'

#8I took a class that went over this in depth like 3-4 years ago. Basically the message was that serial performance is saturating, and the only way to get speed improvements in the future is going to be by exploiting parallelism. However, most programmers, and programming languages, remain stuck in a serial-by-default paradigm. I'm surprised that there hasn't emerged a "parallel-by-default C++" kind of language + hardware system to exploit it to keep things going forward. I find the apparent stagnation extremely depressing.

No one in the office understands why i'm laughing....

In case you dont know, Golang goroutines are a marvel of parallelism. They are coroutines which are dispatched on a few OS threads. So you can use 100% of a multi-cores CPU and yet, spawn, say, 10K of those light threads without worrying about context switches PLUS have them all run concurrently. I've found that golang is one of those rare language, like Lisp, that actually change the way you think about programming. Makes you feel really more powerful.
If you dont know that language, I suggest to run the following and watch your cpu activity and memory (or any metric):
import "time"
func main() {
for i := 0; i
