Question!

Inspiron E1405,Intel Dual Core T2300E (2MB/1.66GHz/667MHz)


That means that the its 2 chips at 1.66 each? so the equivalent of like 3.2? not 100% sure on all the laptop lingo. Thanx in advance

 

No, because it can only run single threaded applications at 1.66Ghz as single threaded apps only use one core. However, it can run TWO single threaded applications simulatenously at 1.66Ghz each by using both cores.
Furthermore, due to the advanced Conroe core and cache, a single 1.66 core of that CPU is somewhat equivalent to a 3.2Ghz Pentium 4.
Basically, you've got a very good CPU there.

 

Yes, 2 chips at 1.66 ghz. The computer won't exactly run at 3.2 ghz speed, but can perform 2 tasks simultaneously both at 1.66 speed. When you're running multiple tasks, this is more useful than a 3.2. Hope that helps.

 

What about the Hard Disk for example.... doesn't it only have one 'needle' that long pointy thing that reads the data on the platters; what if both Cores are accesing or writing to different sections of the hard disk; wouldn't that halt or slower both the running applications simultatenously?

 

put simply, the two cores work at the same time on different things. They two cores DO NOT work togeather on the same application or process.

I'm not too sure about the disk drive thing.. I GUESS that the drive can handle bothe drives as they disk spins incredibly fast.

 

soo all this time the 7200rpm HD was just babying all single core processors? a single core processor wasn't able to reach teh full potential of the hard drive released with 7200rpm and above speeds?

Well I'm also guessing that the 2 cores would have to take turns having access rights to that ONE needle; thus the performace/speed would be similar to a single core processor....

i hope someone can clear this out. ^^

 

Well mabey, but a dual core will always be better than a solo core at eveything it does. I think what it does is data is taken from the hard drive, then lets say you have 40 processes running, well the data might be split 20/20 between each core, basically doubling your performance. Im really just using logic and educated guessing here. So if someone really knows how all this stuff works please educate us.

BTW a 1.66 core solo isnt the same as a P41.66 in performance wise. I believe that my 2.16 duo is equal to a 5.4ghz P4 HT if one existed

 

Wow, thanks guys, wasnt expecting this many responses. BTW Sheff159 that comp listed is GANGSTER... i want that, for free please

 

its more comparible this way:

its x2 the power of normal P4 because it is based on the pM so:

1.66x2 = roughly 3.32

then its dual core which can be closely compared to P4 HT technology so:

3.32 HT

therefore 1.66Ghz Core Duo is comparable to atleast a P4 3.32 HT

 

HyperThreading is totally different from Dual Core. It is much slower and less effective. What HT does, is it uses a single core to simulate a dual core, i.e. makes a single core have the ability to carry out two processes simultaneously.
Hence, a 1.66Ghz Core Duo is more like a 6.64Ghz P4 with HT. A better comparison would be the Pentium D, which is basically two Pentium 4s glued together (hence producing craploads of heat and cannot match the efficiency of AMD's Athlon 64 X2 or the Core Duo). So a 1.66Ghz Core Duo is more like a 3.32 Ghz Pentium D.

Furthermore, not all processes require data from the HD. Most application just load the required data into RAM, and processes it from there (and RAM is nowadays more than fast enough to be accessed by multiple resources simultaneously). Hence, Computers equipped with a 1.66Ghz Core Duo CPU can definitely run TWO single threaded applications simulatenously at 1.66Ghz each by using both cores.

 

Lol, so much information that I cant quite grasp... In the end I just want to know if a 1.66 duo or a 1.8 duo is good... judging by what ive read, either what it sounds more then decent.
