what's the difference between duo and duo 2?

Answer 1

duo 2 is way better than AMD...

Answer 2

johnlee871231 likes to copy and paste, but the answer he gives doesn't address the difference between Core and Core 2 Duo.

Both of those CPUs came from the Pentium M architecture (also known as Centrino) which in turn came from the old Pentium III. Intel practically ditched the dying architecture of the P4, and started back over from where it left off with the Pentium III. The Centrino was a hit when it first came out! It was able to crush the Pentium 4M and any of AMD's mobile CPUs.

The Core processor borrowed much of the same architecture. In fact, there are only a handful of improvements, though each one is significant. The Core 2 Duo came out soon after, and is nearly identical except that it is for the desktop platform and has dual cores.

Answer 3

Duo 2 is for desktops and Duo is for notebooks. But there soon will be a Duo 2 for notebooks also, but the notebook benchmarks on so far aren't impressive. There are a few performance boosts here and there but nothing extraordinary. The Duo 2 for the desktop, on the other hand, is now the reigning processor and blows away AMD.

Answer 4

Duo 2 is the next version of Duo.. they plan to go the same way as they did for Pentium ! (Pentium 2 , 3, 4 etc..)
Duo are the 64 bit processors from Intel meant for desktops nd notebooks !
There have not been any benchmarks to prove anything about AMD vs Duo2 but Intel is claiming that it will be better than AMD !

Answer 5

dual core
A single chip that contains two distinct CPUs that process simultaneously. The first dual core chips for x86-based PCs and servers were introduced in 2005 and include the Pentium D and Pentium Processor Extreme Edition 840 from Intel and the Opteron 800 and Athlon 64 X2 from AMD.


Increased Performance - Similar Power Consumption

Because the continual increase in single core clock speeds were using more and more power and generating excessive heat, dual cores were developed to expand performance without more heat. Dual core systems may use the same or a little bit more energy, but achieve approximately an 80% increase in processing power over single core CPU chips.


For Everybody

Dual-core chips are not just for advanced applications; rather, everyday tasks can take advantage of two simultaneous processing streams. For example, routine downloads of e-mail and software updates that increasingly take place in the background no longer slow down the foreground application. Virus scans and backup programs can be initiated without interfering with the primary task.

Dual-core CPUs are expected to gain significant momentum in the 2006-2010 time frame, not only in servers, but in desktop and laptop computers as well. See multicore, dual processor, Pentium D, Pentium Processor Extreme Edition, Core Duo and core.
