Is this true about how fast CPUs get updated?

You'll have to ask your instructor that, he seems to hav all the statistics

You can get statistics to prove anything...80% of all people know that

Statistics are like people.... If you torture them enough, you can make them say anything  

+1 on that    

Sounds like your gonna have to figure out your project for school all on your own.  

Hi newcomer and welcome to the Tom's hardware forum.

1- Are you talking about CPU or GPU?, because you start with CPU and end with GPU
2- What do you mean with "double every 18 months?

This sounds like a (mis)interpretation of "Moore's Law", which states the number of transistors which can be economically placed in an integrated circuit doubles every couple years... More transistors can definitely process more data, but the law covers only transistors, not throughput. And definitely not clock speed - since that has fallen in recent years, rather than risen.

And accordin to moores law it shoulda been to 10 GHZ.

Lol... so thats what he meant    

Moore's Law covers transistor density, not clock speeds. Like I said: This topic revolves around a Misinterpretation.

ROFL.... lol...    

And here i thought you could use some newly unearthed statistics to predict when ATI will launch the 67** series.    

This guy should really learn to be attentive next time!    

What certification class was it you took?
