Current Core Duo models

[music_pirate]

Hey everyone,

I am close to buying a laptop (within the next few weeks) and I have only just noticed the difference in CPU models offered by dell (and other vendors).

For example, the Dell 640m allows you to have the following CPU config;

ntel® CoreTM Duo Processor T2050 (1.60GHz, 2MB Cache, 533MHz FSB)
Intel® CoreTM Duo Processor T2250 (1.73GHz, 2MB Cache, 533MHz FSB)
Intel® CoreTM 2 Duo Processor T5500 (1.66GHz, 2MB Cache, 667MHz FSB)
Intel® CoreTM 2 Duo Processor T5600 (1.83GHz, 2MB Cache, 667MHz FSB)


Now, the price jump between the 2xxx to the 5xxx is quiet a large ammount. Is the difference between the normal Duo and the Core 2 Duo just in the front side bus? Or is the architecture of the chip different aswell?

Knowing this, is there much difference between the speed of a Duo compared to a Core 2 Duo?

Cheers,

Jason

The 5500/5600 support EM64T, and are otherwise slower than the Core Duo's clock for clock. Core Duo's come with 667/533FSB, however doesn't really need the bandwidth. Core 2 Duo's come with 4MB cache however the 5xxx series only has 2MB enabled.

your forgot the T7200

AFAIK

the 2 series is the old core Duos (yonahs?)

and then the meroms are the T5XXX and T7XXX

with 2mb and 4mb cache respectively

i could be wrong so could someone please confirm

thanx

Getting mixed up there, the T2XXX is the old Core Duos.

whoops fixed

is my understand correct other than that?

Didn't you mean 'faster'?

T20xx are Yonah cores at 533Mhz FSB
T2x00 (where x is not 0) are Yonah cores at 533Mhz/667Mhz FSB

T5xxx are Merom cores with 2MB Cache
T7xxx are Merom cores with 4MB Cache

Advantage of Merom over Yonah:

* EM64T support.
* Slightly faster clock for clock (up to 20% depends on application)

Yeah, thats correct.

No, Merom is slower than Yonah per clock, only with the 4MB cache does it become faster per clock.

Interesting, maybe you are right. Do you have links to any benchmarks on the T5xxx against T2xxx clock for clock?
