core solo vs. pentium m

so...wats the diff between the two. I have not found any benchmarks comparing them yet.

 

Core Solo is a Yonah core, with one fo the cores disabled. This means that it will perform the same as a Core Duo, in single threaded applications. It will perform faster, however, than a Pentium M, due to the improved core. Bear in mind, that the difference will only be felt in processer dependant tasks, like encoding or video rendering. If you are just surfing the Internet or word processing, then there will be practically no difference.

 

Can you enable the dormant core?

 

Core Solos will acheive better battery life than the Pentium Ms and their FSB is higher, the last Pentium Ms produced had a 533 mhz FSB whereas the current Core Solos have 667 mhz FSB.

 

wasnt there a issue about the 667 mhz memory latency? Like the system was fast but the memory wasnt fast enough to keep up ? Or something like that? My pentium M is fast as my brothers 1.6 core duo in standard tasks in windows xp...I also get better battery life then his laptop..

 

The 667MHz RAM has higher latencies as a result of its higher clockspeed, and it performs very similarly to the 533MHz RAM. It's not worth it to pay more for 667MHz RAM if you have to.

In normal tasks, you're not going to see a difference between the processors. Start encoding video or running two CPU-intensive apps at the same time, and you will.
The battery life is dependent on more factors than just the processor, but the Pentium M does not consume as much power as a Core Duo will.

Now as far as the Core Solo goes - there's really no reason to get one, considering how much the Core Duo equipped machines run for.

 

No, you van't enable it. Intel disable through a permanent means, and it cannot be changed or altered after that. A Core Solo core was actually meant to be Core Duo, however, for some reason in the manufacturing, the second core sisn't work. So, Intel decided, as they have done many times in the past, to simply disable this second core, and leave the first one to fuction, therefore resulting in a single cored processer.

 

Also, if they produce Core Duo chips and there is a defect in one of the cores, they can simply disable it and use it as a Core Solo chip instead of scrapping it.
