Higher clock speed = higher IPC ?

IPC isn't just a term for "single-core performance" as a lot of people seem to think these days. It means instructions per clock. Increasing frequency makes more clocks occur per second and hence, more instructions executed per second. Same amount of instructions during each clock though. There's just more of them. IPC is inherent to the architecture and there is no setting you can change which will increase or decrease it.

 

 

No, IPC is seperate from clockspeed. IPC stands for Instructions Per Cycle. A Cycle is another word for Hertz. IPC is the amount of intructions a processor can do in a single cycle.

If it's then why and can you give me a source, If it's false then how does higher clock speed improve the performance ??

How does higher clock speed help ?? I mean it does improve the performance.

Well since the cycle speed is higher, it can still do more instructions.

 

It works in a similar fashion to how a CPU multiplier works. Two values combine or multiply to make a final clockspeed.

Thanks that helped a lot.
