Is there any difference between Intel Core Duo and Intel Pentium Dual Core

It can be described as half, half, half, and half.

The Intel Core Duo E4 series is a product of the Intel Core Duo E6 series that halves the L2 cache to 2MB, removing virtualization technology and other technologies that are rarely used by mass users.

The Intel Pentium Dual-Core E2 series is the Intel Core Duo E4 series with half the Level 2 cache halved to 1MB Level 1 cache. The performance is similar to that of the PentiumD9 series. It's the power consumption and heat generation that go down.

The Celeron 4 is a one-size-fits-all product of the PentiumE2 series.

The Pentium 4 is only available in a single core. And the Pentium D is the model that succeeds the Pentium 4. It is also Intel's first generation of dual-core processors. The technology is still relatively crude. The calorific value is not well controlled.

As for the Core series. This is Intel's latest masterpiece. There is an absolute advantage in performance. Technically, it also maintained a lead over its old rival AMD. And the power consumption control is also very good.

In the future, Intel's CPUs will be codenamed Core. A new era has begun.

Although both the Core and Pentium D are dual-core, the Core's architecture is extremely advanced and uses the technology of shared L2 cache, which makes a qualitative leap in performance compared to the previous generation of processors.

The Core is revolutionary for the evolution of processors, and the performance is more powerful than any previous processor update.

The Pentium 4 supports some 64-bit computing, but not all of them support 64-bit computing. 64-bit is the same content, but the Core performs better, is faster, and more efficient.

The Pentium Dual-Core reduces the L2 cache on top of the Intel Core Duo, making it more cost-effective.

The former is Pentium dual-core, the latter is Core dual-core, and the latter is positioned with higher performance and stronger performance.

Pentium CPU (brand) E6500 (model) Frequency) 2CPUS (dual-core).

Memory 2048M (capacity, that is, 2G memory) Intel(R): Chinese Intel.

Core(TM)2: Chinese Core 2nd generation.

CPU: Processor.

Intel(R) Core(TM)2 Duo CPU means: Intel Core 2 processor.

Intel with R: This is a trademark, the patent trademark has the R logo, Intel.

Core BandTM: This is a corporate trademark, which indicates a certain class or specific brand of a certain product.

Core Duo: Core 2 means, there is quite a big difference between 32-bit and 64-bit.

As far as office work and gaming are concerned, Intel will be better than Pentium.

The question is: how much is the Intel Core 2 Duo better than the Pentium Dual Core, and in what ways?

L2 cache. i5 7 series is also 45nm process In addition to the turbo frequency The instruction set is increased, how much is the performance improved compared to the core2 Q8 Q9, and in what aspects?

Q is basically glue quad-core. No independent L2 cache. The i5 7 series is strong in the native quad-core, with an independent level 2 cache, which optimizes cache reads, so the performance has been slightly improved.

45nm is the old i5 i7, the new one is 32nm, the improvement is great, Intel's strategy is 1 year of new technology, 1 year of new architecture, this year is the new Sandy Bridge architecture, next year the new process is 22nm, every year the improvement is quite large, about 30%.

The old P4 series has been withdrawn from circulation, but I heard that Intel is preparing to reactivate the brand.

The current new multi-core CPU is not significantly improved, mainly because the software that supports multi-core application is not abundant, such as "StarCraft 2" only supports dual-core application. In other aspects, such as power consumption and heat dissipation, the i-series still has some progress over the Q-series.

The former is for desktops, and the latter is for this book, and the former does not have Centrino technology, and the latter is the former with Centrino technology, and as for the better, there is no comparison, because it is a product, but it is only for desktops, and one is for this book, how to compare it.

The premise of attaching the latter label is that you must use the former processor, 945 chipset, and Intel's A B G wireless network card, and the combination of the three is the complete support of Centrino mobile technology, all of which are indispensable.

Dual Core means Core Dual-Core.

Pentium is Pentium (the once famous Ben Four is in this series), and Pentium also has a dual core, that is, Pentium dual core.

Now there is no single-core Pentium, all of them are dual-core, in addition to Celeron dual-core, Core dual-core.

They are divided by series (to put it bluntly, it is the price, grade and performance), the products of the same period are generally Core Dual-Core, "Pentium Dual-Core", Celeron Dual-Core, in fact, the hardware structure of the Core Dual-Core and the Pentium Dual-Core produced at the same time is actually the same (the same semiconductor production line), but when packaging, some device functions or instruction sets are artificially shielded, or some hardware units are shrunk, thus forming the Pentium dual-core, so the performance of the Pentium dual-core family is not as good as the Core dual-core family.

If it's a general Internet or playing a mini-game, it's almost the same, but there are some differences when playing games.

I'm sorry, it's taken so long to see the purpose of your question, so I should give you the knowledge

The Intel Pentium Dual Core you are talking about is dual-core (Intel Pentium Dual-Core), Intel Pentium is Intel Pentium, and there is no single core or dual-core (Pentium currently has no single-core production line). The E2200 and E2180 you said are similar, a grade of processor, almost exactly the same in structure, but E2200 is relatively a little better, almost invisible.

These two are processors from a few years ago, and they have long been discontinued, and these two processors were relatively popular in 08.
