dual core and core 2 duo

Dual core stands for the type of processor. An AMD Athlon x2 6000 is a dual core chip. Core 2 duo is Intels naming for their new dual core architecture eg core 2 duo e8400. Both represent the same thing just with different names as a core 2 duo is a dual core proc.

Hope that helps:)
 
how can core 2 duo be their naming convention if they had a "dual core" named chip as well?

AFAIK core 2 duo > dual core

may be wrong here....

Hi GUys

What is the difference ?

Thanks

If u were just referring to Intel chips, an intel dual core could be budget core2duos in the E2xxx and E4xxx series...which is basically the same as core2duo chips with less cache and no virtualization.

There's also the pentium (D) dual cores, older technology based on netburst (same as pentium 4) which is clocked higher and cheaper...and much hotter and slower.

So an intel dual core can be any of those, but a core 2 duo is anything from E6xxx series and up....maybe the E5200 also a core2duo?

Thats how I understand it anyways :D
 
ya cause my pentium 4 shows two processors but I DONT have a core 2 duo.

I think the Dual Core CPU's are basically the same as the Pentium 4/D series - just a "Virtual" Dual Core or something....
 
Celeron Dual Core/Pentium Dual Core and Core 2 Duo and AMD Athlon x2 procs are all dual core chips. The older p4 chips use Hyperthreading to create a virtual extra core. All Intel processors that have a E before the numbering eg E1200 and E8400 have 2 physical cores sandwiched together to make them a proper dual core proc. The Celeron and Pentium branded dual cores are cut down versions of the Core 2 Duo chips.

Thats as far as I know :)

P4 has hyperthread which shows 2 cores...not the same as pentium D

A long time ago AMD said Intel cant make proper dual cores, they just took 2 pentium 4s and slapped them together....resulting in something similar to a dual cpu motherboard with 2 similar cpus.

Now this configuration is slower...

The newer dual cores (AMD's and core2duo) are actually dual "cores" and not 2 cpus, they share the same cache but have two processing "departments" which is faster than the older dual cores.

Hence pentium Ds are speced: clockspeed(ghz)/x mb+x mb cache
whilst core2duo or newer dual core are: clock(ghz)/x mb cache shared

Heres an example:

P4 = 1 receptionist with 2 hands(hyperthread)
Pentium D = 2 receptionist with their separate desks and files, offices etc
Core2duo = 2 receptionists sitting next to each other with their files shared in the middle

Cant think of any better example :D

OOOh I see,

The diff between the e2180 and e7200 is:

Clockspeed (2ghz vs 2.53)
core design (65nm vs 45nm)
which leads to overclocking potential (reaches 3.6ghz vs 4.4ghz)
which means voltage difference (1.35v vs 1.25? stock)
which leads to temp difference (~40degrees vs 30 degrees) (rough estimates lol)
and shared cache (2mb vs 3mb)

Get the pc with the E7200 rather!
