Why a 1.7GHz Centrino can be faster than 2.53GHz desktop processor ? I read this in a news. [?]

In summary: Originally posted by SaintIn summary, the 1.7GHz Centrino can be faster than the 2.53GHz desktop processor because the amount of HZ doesn't tell the whole story behind how powerful and fast a processor is. Some of those factors are: bus speed/size, number of registers, instruction set, op-code cycle times, logic-gate structure, transistor size, amount of cache memory, software controling the cpu (i.e. BIOS), among other things.

The same reasons Athlon 2000xp (1.67ghz) matches a Pentium 2.0ghz. The amount of HZ doesn't tell the whole story behind how powerful and fast a processor is. What those factors are I'm not entirely sure

BTW, isn't the centrino only for laptops/portables?

J-man, yeah. Laptops only. And you missed the primary factor in the efficiency difference between most chips: pipeline length. The reason the p4 is slower per clock cycle than the p3 is they doubled the length of the pipeline. It takes 20 clock cycles to process an individual instruction. There may be 20 different instructions in the pipeline, but when an operation depends on the results of another, the later operation has to wait before it can be run.
The reason the pipeline was lengthened is there is a relationship between how high a processor will clock and how long the pipeline is. Its a tradeoff (not sure why though).
The centrino has a shorter pipeline than the p4 (not sure how much though).

how about the design of AMD Athlon ?
What is better than intel P4 ?

I thought I included that in with bus size; I meant both number of conduits and physical dimensions, but I suppose I could have elaborated. Chalk it up to laziness on my part.
I could be wrong, but I believe it mainly has to do with the delay times.

It depends on what you mean by better, or what is better for your situation. The answer would vary depending on what is important for you be it price, size, power consumption, ips, ease of integration, instruction set, availability, etc.

The Intel Xeon could be thought of as "better" because it allows duel-processor configuration.

Xeons are nothing.. forget them...
Itaniums kick anythings butt, even PPC 970 :(

Why intel wants to delay the project of 64bits CPU for desktop?
The news said that intel will follow suit if AMD is successful.

FAQ: The Speed of Intel Centrino CPU: 1.7GHz vs. 2.53GHz Desktop Processor
What is the difference between the Intel Centrino 1.7GHz and 2.53GHz desktop processors?
The main difference between these two processors is their clock speed, with the 2.53GHz processor having a higher clock speed than the 1.7GHz processor. This means that the 2.53GHz processor is capable of performing more calculations per second, making it faster for tasks that require a lot of processing power.
Can the speed of the Intel Centrino CPU be unlocked?
No, the speed of the Intel Centrino CPU cannot be unlocked. The clock speed of a processor is determined by its hardware and cannot be changed or unlocked through software or other means.
Is the 2.53GHz desktop processor always better than the 1.7GHz processor?
Not necessarily. While the 2.53GHz processor has a higher clock speed, there are other factors that can affect the overall performance of a processor. These include the number of cores, cache size, and other features. It is important to consider all of these factors when determining which processor is better for your specific needs.
What tasks benefit from a higher clock speed?
Tasks such as video editing, gaming, and other applications that require a lot of processing power can benefit from a higher clock speed. These tasks often involve a lot of calculations and can take advantage of a processor's higher clock speed to perform them more quickly.
Is it worth upgrading from a 1.7GHz to a 2.53GHz processor?
It depends on your specific needs and usage. If you regularly perform tasks that require a lot of processing power, then upgrading to a 2.53GHz processor may improve your overall performance. However, if you primarily use your computer for basic tasks such as web browsing and document editing, the difference in speed may not be significant enough to justify the cost of upgrading.
