623326 2007-12-20 22:42:00 well for a start its NOT 4ghz this person is 'playing dumb' as many do and multiplying a 2ghz core 2 duo by two so that they are saying its 4ghz not 2 cores each running at 2ghz.......... drcspy (146)

623331 2007-12-21 19:07:00 I'd like to ask about this 2 GHz/4 GHz argument. If you think of GHz as cycles per second (for simplicity's sake let's use two 1 Hz CPUs and assume that the system can perform one operation per cycle) then the system as a whole would surely still accomplish two operations per second and therefore be equivalent to 2 Hz (or in the case of that laptop, 4 GHz).

Apologies if that was hard to follow!

623332 2007-12-21 19:14:00 I think it's a bit steep...especially with only 2 Mb of RAM!!?? - (obvious typo) lol

I see down further it does say 2Gb but I wish some people would proof their listings first, it saves wasting time & 'being led up the garden path' eh.

623333 2007-12-21 19:15:00 It says it only has 2MB RAM, but below he says it has 2GB of RAM. :illogical

EDIT: You beat me to it fnphoto. :D

623334 2007-12-21 19:27:00 If you think of GHz as cycles per second (for simplicity's sake let's use two 1 Hz CPUs and assume that the system can perform one operation per cycle) then the system as a whole would surely still accomplish two operations per second and therefore be equivalent to 2 Hz (or in the case of that laptop, 4 GHz).

Ok lets get technical about it.:D

www.behardware.com
IPC and frequency

The CPU performances can be evaluated with the number of instructions processed in one second, in other words the IPS. It is equal to :

ips = i/c x c/s

C corresponds to the number of processor cycles and IPC to the average number of instructions processed per cycles. The cycletime is the number of cycles per second, or in other words the clock frequency, called F.

So:

IPS = IPC x F
