Intel Core 2 Duo Vs Core Duo

[x-pert]

Intel's really to blame here for a horrific naming convention. Any half-conscious marketing executive would commit suicide before putting both a numeral 2 and the word "duo" in the name of a product, particularly when there's also a product with "solo" in the name. But let's put that aside and look at the specs of each.

Core Duo is Intel's first dual-core CPU. It's a whole new architecture for Microsoft, using two cores on a single die, which, put simply, gives you two chips in one package. Running at lower speeds than the old Pentium line, the Core Duo conserves substantial power vs. ratcheting up clock speed while offering what was, at the time, record-breaking performance.

Now there's Core 2 Duo. In many ways Core 2 is the same as Core: The chips are built using the same production process and fit in the same sockets as Core Duo chips. Putting aside Core 2 Extreme (a fancy version of the Core 2 Duo), you won't see many spec changes: Both chips have the same frontside bus speed of 667MHz, but Core 2 Duo is now available at somewhat faster clock speeds (as I write this, 2.67GHz chips are available). The frontside bus communicates between the CPU and RAM (and other components), and it's a notorious performance bottleneck for computers. The Core 2 also has the same L2 cache that the Core has. However, there are architecture changes to the silicon that give the Core 2 more sophisticated processing abilities. Both chips exist in desktop and laptop versions.

Why does all of this matter? Performance, pure and simple. In my tests, Core 2 Duo computers outperform Core Duo computers on tasks across the board, from rendering graphics and video to spell-checking documents. The speed improvement varies widely, but on average it's about 30 percent. That's significant in an industry that thrives on tiny, incremental improvement. Better yet, there's not an appreciable difference in battery life on notebooks, as power consumption for both chips (at the same clock speed) is about the same.

Now let's consider pricing. Initially, Core 2 chips were more expensive than Core, but that has changed, as Core is practically gone from the desktop market now. Surprisingly, you can now get a 2.13GHz Core 2 CPU for less than the price of a 1.66GHz Core CPU.

Still, expect to see some systems still on the market that use the Core CPU, especially in laptops. Performance is still very good with Core, so don't feel like you're getting second-class goods if you buy a Core Duo notebook, but remember you are buying a chip that Intel is no longer actively selling, and prices for Core 2 systems aren't really any different than they were for Cores. If it was my money, I'd hold out for a Core 2 system unless you got a great deal on a Core... which will be all but vanished from the market in a matter of months.

Hmmm....

Then, are Pentium D CPUs also from Core Duo series??? :confused:

yup exactly. i read about it yday.. :yes::yes:

Mokaa?? :confused:

yup exactly. i read about it yday.. :yes::yes:
:D k, had doubts ;)

Pissu thamai!!! :lol: :lol: :lol:

[Anusha]

yup exactly. i read about it yday.. :yes::yes:
What? :S

[lahirumam]

How come Pentium D = Core Duo??? It Cant be... :)

Eka thamai :rolleyes:

Eka thamai :rolleyes:

There aren't any Core Duo desktop processors right?? only for notebooks ne?.... :confused: :confused:

No officially. But if you can grab a CPU from somewhere (it has to be OEM, because they are not sold in retail), AOpen has a motherboard that supports them. Some people have Core Duos on desktops. Same as some people have AthlonXP-M on their desktops.

[chamithal]

Well! I haven't even seen any Core duo desktops but av seen a lot of Laps! Pentium D is 2 P4 cores while Core duo has a different architecture... They are definitely not the same! I think Core duos were specially developed for mobile PCs as it consumes less power while delivering more performance...

:yes: :yes: :oo: :oo:

Experience the powerful multitasking capabilities of an IntelŪ PentiumŪ D processor-based PC with revolutionary Intel dual-core technology.

This was on www.intel.com

But I reckon that they are considering Pentium D as the first dual core technology based processor.

Dual core technology is the first step of Core duo and Core 2 duo... :yes: :yes: :yes:

Well, they made the first dual core CPUs by combining two Pentium 4s on the same die. Pentium D is not the only dual core made at that time. Pentium D doesn't support Hyperthreading. But Pentium Extreme Edition Dual Core (it's not called Pentium D) has Hyperthreading as well, i.e. it can multiplex a maximum of 4 threads at a time.

Core micro architecture is a revamped architecture used in Pentium M. It was developed from the Pentium 3 architecture. Can't remember its name :D It's totally different from Netburst, the late Pentium 4, D and EE.

Not only Pentium extreme dual core but the Intel Pentium® 4 Processor Extreme Edition also supports Hyper-Threading Technology

Dual-core refers to a CPU that includes two complete execution cores per physical processor.

It has combined two processors and their caches and cache controllers onto a single integrated circuit

Dual-core processors are well-suited for multitasking environments because there are two complete execution cores instead of one, each with an independent interface to the frontside bus. Since each core has its own cache, the operating system have sufficient resources to handle most compute intensive tasks in parallel. :cool: :cool: :cool: :yes: :yes:

:confused: :D

so Pentium D cpus are nt core duos, ok :D

Of course :S
I wasn't talking about P4's there.

Well, Pentium D and Dual Core EE CPUs don't have a shared L2 like the Core 2 Duo's have.

I thik it is YONAH

[x-pert]

I thik it is YONAH


Deff.... it has to be Yonah or Merom... :yes: :yes: :yes:

But its 2 kinds of processors

[gayannr]

Well, Pentium D and Dual Core EE CPUs don't have a shared L2 like the Core 2 Duo's have.
:yes: :yes:
but i think they share the same cache controller

[x-pert]

I thik it is YONAH


Yonah's are not Core 2 Duos, they are Core Duos, which are still based on the old NetBurst architecture introduced with the Pentium 4s.

The Meroms are the Core 2 Duos, which are based on the new Core architecture, which is much better.

[Anusha]

I thik it is YONAH
I'm talking about the P3 architecture.
Yonah = Core Duo
Dothan = single core version of Yonah
Merom = Mobile C2D..........

[Anusha]

No! They are not based on Netburst! OMG! How can someone put a Netburst CPU inside a Lappie? :shocked:

[Anusha]

:yes: :yes:
but i think they share the same cache controller
Hmm... I don't know about that. I don't think so. I mean, the cache controller has to be at least modified to control shared caching, if not rebuild it from the sketch. I think the Core Duo's have a new cache controller and the same thing is improved in the case of Core 2 Duo.

Hey i thought u were talking abt Core Architecture
