My brother just got a 1.6ghz dell laptop and it seems to run almost twice as fast as my desktop does. And last question, how does the x1400 compare with the radeon 9600? I'm just trying to figure out if it'll be a good upgrade or not.
It all depends what processor it is. Clock speed is not everything.
You probably have an old Pentium 4 desktop CPU. What it comes down to is how much work a CPU can do per clock cycle. The higher Instructions Per Clock (IPC), the higher performance it has than a CPU at the same exact clock speed. The Pentium M CPU in your brother's Dell laptop can do approximately 1.75 times more work per clock cycle than your Pentium 4. Thus, at the same clock speed, it wipes the floor with your desktop!
Here is a rough estimation of performance:
1.8GHz Pentium M = 2.0GHz Athlon 64 = 3.0GHz Pentium 4 (Prescott Core)
That is just a rough estimate, and each CPU has strengths & weaknesses. So while the Athlon 64 & Pentium M will kick ass in gaming, the Pentium 4 will be very fast in video/audio encoding.
This is a very simply explanation, I hope it helps.
