Is the Core 2 Duo the same as Core Duo?
Just checking Lion compatibility with my Mac Mini (Intel Core Duo) and Macbook (Intel Core Duo). Both about 3-4 years old. The system requirements for Lion specify Intel 2 Core Duo. Is this different?
Last MacBook Intel Core Duo came out in 2005, it's 6 years old.
Last MacMini with a Core Duo came out in 2006, it's 5 years old.

Is the superdrive in the Core duo Mac mini and the G4 mac mini the same ?
I have a G4 mac mini with a busted super drive and someone is selling a core duo mac mini with ram and a super drive but a bad logic board.
Is the super drive the same in both machines ?
How tough is it to swap it to the other ?
I've done some Hard drive installations and ram installations using the macfixit guide but don't want to bust it I'm certainly not Mr Fix it.
Thanks in advance.They are not the same.
Compare the PowerPC Mac Mini specs from Archive.org:
"Optional SuperDrive (DVD±RW/CD-RW): writes DVD-R discs at up to 4x speed, writes DVD-RW discs at up to 2x speed, writes DVD+R discs at up to 4x speed, writes DVD+RW discs at up to 2.4x speed, reads DVDs at up to 8x speed, writes CD-R discs at up to 16x speed, writes CD-RW discs at up to 8x speed, reads CDs at up to 24x speed"
To the Intel Mac Mini specs today:

Replacing/Upgrading the 15" 2.16 GHz Intel Core 2 Duo MacBook Pro HDD?
I was wondering if it is possible to replace the 15" 2.16 GHz Intel Core 2 Duo MacBook Pro HDD from a 5400 RPM to a 7200 RPM. I plan on recording using Logic Pro so I will most likely need a faster hard drive. If so, what are some good, compatible hard drives to look into.
Mac OS X (10.4.9)As asked here perhaps 1000 times a day, and findable
with a simple search you can, but you can void your
warranty if you don't do it right and there is some
work involved. Spare the grief and get an external
drive with a fast 2.5" drive in it and add to your
capacity the entire value vs. the difference.
It is very tiring to see you respond to everyone who asks this question with "get an external drive". I'm sure there are a lot of people out there who want more storage WITHOUT having to tote extra gear around.
Yes external drives are useful, but they don't answer the question asked.

Is there a difference between the Intel Core 2 Duo & the Intel Core Duo?
I am looking to buy a new laptop, and I wanted to know if there is a big or major difference between the Intel Core 2 Duo processor, compared to the Intel Core Duo.
I currently have a powerbook G4 and it has a 1.67 GHz PowerPC G2 Processor, which I have noticed isn't that great, I can't download the new snow leopard software update, nor watch movies from Netflex and other stuff like that. Its pretty annoying, so that is why I was asking about the difference between the other two processors, I want to know if it doesn't matter or which one is the best before I buy.
I'm pretty computer dumb when it comes to this stuff that's why I'm asking.
Thanks in Advance.
- Heather TelCore 2 Duo processors are newer and more powerful (and thus faster) than Core Duos. Apple's current notebook computers all use Core 2 Duos, so if you buy new, that's what you'll get. The earliest MacBooks and MacBook Pros had Core Duos in them, but the last of those models was discontinued late in 2006.

whats the lastest software i can put on a macbook 2.2 GHz intel core 2 Duo. the software i have on the laptop right now is the Mac OS X (10.6.7)?
It would help to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up check the Model Identifier and post it back here.
If it's the Late 2007 model 3,1 then 10.7 is the most that it can run.

What's the difference between the Core 2 Duo and the Core Duo
I recently bought a new Macbook (Original) with an Intel Core 2 Duo processor.
I gave my old one to my younger cousin. It has just an Intel Core Duo processor.
What does that "2" mean?
Does it mean the processor is faster?
I was guessing it means that I can have more RAM (because this can hold 4 GB instead of 2 GB, like my previous Macbook)...
Both these Macbooks have only 1 GB of RAM, yet the new one seems MUCH faster. The only real difference in technical specs is the processor. Could the processor be responsible for the much faster computer, or is it simply because it's a new computer?
Thanks!iSMH wrote:
The Core2Duo is faster than the CoreDuo. The other difference is that the Core2Duos can see 4GB of RAM, CoreDuo can only address 2.
Part of that has to do with the chipsets, although I've heard that some of the Intel chipsets work with both the Core Duo and the earlier Core 2 Duo.
The Core Duo is the dual-processor version of the Core processor.
The Core 2 Duo is the dual-processor version of the newer generation Core 2 processor.
The Core 2 series is more advanced. They likely are produced on faster semiconductor processes in smaller "geometries". I think part of it is a higher operating clock speed, but it could also include advances in processing power where it takes fewer average clock cycles to complete certain instructions. There could be things like more pipelines, faster/more arithmetic logic units, and other architectural improvements that makes it work faster overall even without clock-speed increases. -
I'd like to upgrade my operating system on my iMac. Like I said, I have an iMac running OS X v10.5.8. The processor is a 2GHz Intel Core 2 duo. Can I safely upgrade to Lion OS?
You will need SL (10.6.8) to download and install from the App Store. You can buy a thumb drive with Lion and by-pass the SL install, but you are not saving any money by doing it that way.
Mountain Lion comes out next month. Just in case you want to wait. And be aware that neither Lion or Mountain Lion will run PPC applications.
Your computer may pass, but check here for full requirements.

Is the 2.16Ghz the equivilent to 4.32Ghz Because of Core 2 Duo?
I read a post a few pages in on the main forum, and someone was talking about the 17inch MBP having 4.66Ghz of power... Is this the correct way of calculating it? If it is, then I feel like I've bagged a bargain (the price of my 15inch MBP Being {£1349})
I know that my pc's AMD Athlon's processor is actually 3Ghz (marked as 2Ghz but actually 3 compaired to Intel's older chips)That's like asking "If two cars are each going 60 MPH does that mean that together they are going 120MPH?" The reason we are seeing multi core procs and multi proc computers is that once CPUs started pushing 3-4 GHZ the heat became impossible to control. The newer procs are using a more efficient architecture that allows them to accomplish more per cycle. Therefore, the procs can run at much lower clock speeds which translates into much cooler chips. Adding additional CPU cores allows the workload to be distributed over several CPUs, adding to the efficiency (speed) of the computer.

Is the core i5 the same as dual-core i5
I bought a latest generation macbook, mid 2013, last week. when I open "about this mac" on the top control bar, it says the processor is 1.3GHz Intel Core i5. But the offical website shows the processor is 1.3Ghz Dual-Core i5. My question is why my macbook air lost one. Is it a cheating?
Welcome to Apple Support Communities
Your MacBook Air has got a dual-core Intel Core processor, but About this Mac doesn't indicate it. You can be sure you have a dual-core Intel Core, so don't worry about this -
What's with the obsession for the new MB Core 2 Duo?
I just don't understand why many MB users are crying about the Macbook C2D which just came out today. I don't see much of improvement of this generation compared to the 1st one. Seems to me the only major change is just the CPU, which generally gives you what, 10% of speed difference, from the reviews ive read (the advertised 25%? I don't think so.). How many of you can really tell the difference?
The performance bottleneck of the Macbook is at the graphic card, not the CPU. If Apple had released the Macbook C2D with a dedicated graphic card, even if it was just an x1300 or an old-school x300, I would say this is a great buy and I would regret for my purchase of the old macbook a few months back, too. But unfortunately, that's not what just happened.
Anyway, looking at the new macbook C2D today, I'm still quite happy with my old macbook. Not a thread of regret at all. What about you guys?The big deal is the 64-bit capability of the new chip. Being that Leopard is being advertised as being a fully 64-bit capable OS, there's a possible performance benefit in the future, along with more RAM capacity for the Mac Pro's. As of now, there's no reason to rush out and get one if you've got an "old" model.
In fact, I'm wondering if there won't be another refresh with Leopard that offers the newer PRE-N wireless chips like in the pro models for support for the next-gen Airport. Thus, I don't think I'm going to bite on this new model. I believe the next refresh will offer a lot more in term of new features and performance.

Can the newer logic boards still read the mac pro 1.1 2.66ghz duo core proc
i just bought a G5 and i am looking to upgrade it. I just bought the 2.66 ghz processors, and I am looking to buy a new logic board and was wondering if i bought a 2009 logic board would it still be compatible with the 2006 processors?
Unlike PCs (that stayed with one Hardware manufacturer year after year, and therefore did not change much of anything for decades) Mac hardware has been allowed to evolve over time. Macs have gone through several different processors from different manufacturers over the years.
It is a tribute to the superior engineering of the Mac Operating System that Apple has been able to extend and migrate Mac OS to accommodate wildly different hardware. Enormous incompatibilities tend not to appear all-at-once.
But change must eventually come. If you fancy running Mac OS X 10.6, it runs only on Intel Processors. The G5 is the last of the Motorola/IBM PowerPC processor series. The first was released about 1994 (PowerPC 601 in the 6100 series) and the last G5 was discontinued about 2006. There are a great number of people still running G4 and G5 Macs, generally using Mac OS X 10.4 and 10.5. There are still a number of fairly vibrant forums on this Hardware and Software.
But if you want to end up with a working Mac Pro, you need to start with a Mac Pro chassis, not a G5 chassis. As Kappy points out the Processors, drives, peripheral interfaces, chassis cut-outs, Power Supply and most importantly Airflow/Cooling (with processor-controlled fans) are completely different, and there is no sensible way to adapt a G5 chassis to intel processors.
Starting with a Mac Pro chassis, the upgrades will only be difficult instead of impossible. -
Ask the Expert: Hierarchical Network Design, Includes Core, Distribution, and Access
Welcome to the Cisco® Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about hierarchical network design.
Recommending a network topology is required for meeting a customer's corporate network design needs in their business and technical goals and often consists of many interrelated components. The hierarchical design made this easier like "divide and conquer" the job and develop the design in layers.
Network design experts have developed the hierarchical network design model to help to develop a topology in discrete layers. Each layer can be focused on specific functions, to select the right systems and features for the layer.
A typical hierarchical topology is
A core layer of high-end routers and switches that are optimized for availability and performance.
A distribution layer of routers and switches that implement policies.
An access layer that connects users via lower-end switches and wireless access points.

We are discussing the following without any product line, discussing the concept of hierarchical design, which will help you to take decision which model is better for you Two Layer or Three Layer hierarchical model.
Two-Layer Hierarchy
In many networks, you need only two layers to fulfill all of the layer functions—core and aggregation
Only one zone exists within the core, and many zones are in the aggregation layer. Examine each of the layer functions to see where it occurs in a two-layer design:
Traffic forwarding—Ideally, all interzone traffic forwarding occurs in the core. Traffic flows from each zone within the aggregation layer up the hierarchy into the network core and then back down the hierarchy into other aggregation zones.
Aggregation—Aggregation occurs along the core/aggregation layer border, allowing only interzone traffic to pass between the aggregation and core layers. This also provides an edge for traffic engineering services to be deployed along.
Routing policy—Routing policy is deployed along the edge of the core and the aggregation layers, generally as routes are advertised from the aggregation layer into the core.
User attachment—User devices and servers are attached to zones within the aggregation layer. This separation of end devices into the aggregation permits the separation of traffic between traffic through a link and traffic to a link, or device. Typically, it is best not to mix transit and destination traffic in the same area of the network.
Controlling traffic admittance—Traffic admittance control always occurs where user and server devices are attached to the network, which is in the aggregation layer. You can also place traffic admittance controls at the aggregation points exiting from the aggregation layer into the core of the network, but this is not common.
You can see, then, how dividing the network into layers enables you to make each layer specialized and to hide information between the layers. For instance, the traffic admittance policy implemented along the edge of the aggregation layer is entirely hidden from the network core.
You also use the core/aggregation layer edge to hide information about the topology of routing zones from each other, through summarization. Each zone within the aggregation layer should have minimal routing information, possibly just how to make it to the network core through a default route, and no information about the topology of the network core. At the same time, the zones within the aggregation layer should summarize their reachability information into as few routing advertisements as possible at their edge with the core and hide their topology information from the network core.
Three-Layer Hierarchy
A three-layer hierarchy divides these same responsibilities through zones in three vertical network layers,
Traffic Forwarding—As with a two-layer hierarchy, all interzone traffic within a three- layer hierarchy should flow up the hierarchy, through the layers, and back down the hierarchy.
Aggregation—A three-layer hierarchy has two aggregation points:
At the edge of the access layer going into the distribution layer
At the edge of the distribution layer going into the core
At the edge of the access layer, you aggregate traffic in two places: within each access zone and flowing into the distribution layer. In the same way, you aggregate interzone traffic at the distribution layer and traffic leaving the distribution layer toward the network core. The distribution layer and core are ideal places to deploy traffic engineering within a network.
Routing policy—The routing policy is deployed within the distribution layer in a three- layer design and along the distribution/core edge. You can also deploy routing policies along the access/distribution edge, particularly route and topology summarization, to hide information from other zones that are attached to the same distribution layer zone.
User attachment—User devices and servers are attached to zones within the access layer. This separation of end devices into the access layer permits the separation of traffic between traffic through a link and traffic to a link, or device. Typically, you do not want to mix transit and destination traffic in the same area of the network.
Controlling traffic admittance—Traffic admittance control always occurs where user and server devices are attached to the network, which is in the access layer. You can also place traffic admittance controls at the aggregation points along the aggregation/core edge.
As you can see, the concepts that are applied to two- and three-layer designs are similar, but you have more application points in a three-layer design.
Now the confusion takes place in our minds where do we use Two Layer and where the Three layer hierarchical model.
Now we are discussing that How Many Layers to Use in Network Design?
Which network design is better: two layers or three layers? As with almost all things in network design, it all depends. Examine some of the following factors involved in deciding whether to build a two- or three-layer network:
Network geography—Networks that cover a smaller geographic space, such as a single campus or a small number of interconnected campuses, tend to work well as two-layer designs. Networks spanning large geographic areas, such as a country, continent, or even the entire globe, often work better as three layer designs.
Network topology depth—Networks with a compressed, or flattened, topology tend to work better as two-layer hierarchies. For instance, service provider networks cover large geographic areas, but reducing number of hops through the network is critical in providing the services they sell; therefore, they are often built on a two-layer design. Networks with substantial depth in their topologies, however, tend to work better as three-layer designs.
Network topology design—Highly meshed networks, with many requirements for interzone traffic flows, tend to work better as two-layer designs. Simplifying the hierarchy to two levels tends to focus the design elements into meshier zones. Networks that focus traffic flows on well-placed distributed resources, or centralized resources, such as a network with a large number of remote sites connecting to a number of centralized Data Centers, tend to work better as three-layer designs.
Policy implementation—If policies of a network tend to focus on traffic engineering, two-layer designs tend to work better. Networks that attempt to limit access to resources attached to the network and other types of policies tend to work better as three-layer designs.
Again, however, these are simple rules of thumb. No definitive way exists to decide whether a network should have two or three layers. Likewise, you cannot point to a single factor and say, “Because of this, the network we are working on should have three layers instead of two.”
I hope that this helps you to understand the purposes of Two Layer & Three layer Hierarchical Model.
Best regards,
Ahmad Manzoor
