Core Duo is divided into two kinds, Core and Core 2, Core are 32-bit, Core 2 is 64-bit Literally Core 2 is obviously the upgraded version of Core. What is the difference between the two? First of all, the Core 2 CPU supports the mobile 64-bit computing mode, which provides a solid hardware foundation for the future era of faster computing. The high-end 7 series has 4MB of L2 cache, which is double that of Core's 2MB! A larger L2 cache means more powerful multitasking capabilities and a much shorter processing time. Originally, the Core 2 CPU's front-side bus was supposed to be 800MHz, but in order to meet the needs of the Centrino III platform, it is still the same as Core at 667MHz.The Core 2 CPU also adds support for EM64T and SSE4 instruction sets. The support for EM64T allows the CPU to have more memory addressing space, which will not only help it to face the memory killer VISTA operating system in the future, but also prolong the lifecycle of the Core CPU. Of course SSE4 instruction set compared to Core SSE3 instruction set, more emphasis on the multimedia processing speed and have a number of optimizations Now the Pentium series of desktop computers there are two kinds of dual-core, one was born in the Core 2 before, called the Pentium D, one was born in the Core 2 after, more Pentium E. The Pentium D is a crappy dual-core, high-frequency, low-power, power consumption and heat generation are extremely large, so it has already been eliminated, and now you can't buy a basic! The Pentium D is a crappy dual-core. After the birth of Core 2, with its excellent performance and low-frequency high-energy, low heat, low power consumption, good overclocking performance by everyone's favor, but suffering from the price is too expensive, low-end users can hardly afford, so it launched a series of castrated version of the Core 2, but Intel named him Pentium E, the reason why Intel has to be called so on the one hand, may be in order to commemorate the Pentium series of achievements in the past (otherwise Pentium) On the one hand, Intel may have called it that to honor the past achievements of the Pentium series (otherwise the Pentium series would have been phased out long ago), so the Pentium E is also the lower-end series of the Core 2, replacing the crappy PD in the past. The characteristics of the Pentium E are exactly the same as those of the Core 2, as it adopts the same advanced architecture, but with a slightly lower mainframe frequency and lower L2 cache, and therefore slightly worse performance. On the other hand Intel at the same time is trying to draw the line between Core and Pentium in this way. INTEL is not willing to reduce the price of Core Duo to fight this battle with AMD, so it chose to shrink the CPU this way to reduce costs, and AMD to compete in the low-end market of this notebook

After the shrinking of the CPU, we are accustomed to call the Pentium Duo,

The real Core Duo is labeled as follows: Intel core duo and intel core 2 duo, which stand for Core Duo, respectively.

The real Core Duo is labeled: intel core duo and intel core 2 duo, which represent Core 1 and Core 2 respectively

And the shrunken Pentium Duo is labeled as pentium dual core inside

So when you buy a book, you must look at the trademark on the bottom right corner of the book, what is labeled, or you will be fooled by JS without knowing how it works

The Pentium Duo's naming is not fully summarized so far. The Pentium Dual-Core is a new generation of computer graphics cards that are based on the Pentium Dual-Core, which is a new generation of computer graphics cards that are based on the Pentium Dual-Core, which is a new generation of computer graphics cards that are based on the Pentium Dual-Core, which is a new generation of computer graphics cards that are based on the Pentium Dual-Core.

Such as Core T2050 shrunken version of T2060, T2250 shrunken version of T2080

Recently came out of the T2310, although the brand T23**, as if with the T2300 how close, and also more than 2300 10, so that unfamiliar with the friends of the book at a glance, thought it was better than the 2300 it is the 2300 Upgrade it

That would be a big mistake and a big mistake

This is precisely to cater to the majority of the low-end market and a castrated version,

Core Duo T2300 processor, the main frequency of 1.66GHz, 2MB of L2 cache.

And T2310 main frequency 1.46GHz, 1M L2 cache,

Only commendable is: 2310 is 64-bit - this is also forced by AMD, in order to fight against AMD and now vista on the 64-bit requirements of the helpless move, sacrificing computing power, in order to support the value of 64-bit. In exchange for 64-bit support value and not worth ......

The following details of each generation of u:

Even did not search the whole, because now intel new product speed is too fast, almost every month there are new varieties out, here is just a slight introduction to tell you, don't follow the old The level of computing CPU to see, the larger the number of computing power is stronger just for the same series, such as Core series. If you can't stand Core or Pentium, it's easy to make a mistake - if you know something about u, you can still look at the parameters directly

Intel, in order to reduce costs, will be a CPU derived from a variety of different models, but let the people look at the dazzle, especially T2XXX, there are eleven models:

Intel, in order to reduce costs, will be a CPU derived from a variety of different models, but let the people look at the dazzling, especially T2XXX, there are eleven models:

Core Duo T2500 T2400 T2450 T2300 T2300E T2250 T2350 T2050 has been basically discontinued

Pentium Duo T2130 T2080 T2060, as well as the newer T2310,

Compare the following:

T2500, T2400. T2300, T2450, T2300E, T2050, T2060

First of all, the ones with the tail number T2X00 all have a front-end bus of 667MHz and a L2 cache of 2M, only the main frequency is different,

T2500 has a main frequency of 2.0GHz,

T2400 has a main frequency of 1.83GHz,

T2300 at 1.66GHz, and the other models can be seen as derivatives of them.

The T2450 is compared to the T2500, the T2350 to the T2400, and the T2250 and T2050 to the T2300, all with a 2M L2 cache, a front-side bus that has been reduced from 667MHz to 533MHz, and a slight difference in the mainframe frequency (the T2450 is the same as the T2500, the T2350 is 1.86GHz, the T2250 is 1.73 GHz for the T2350, 1.73GHz for the T2250, and 1.60GHz for the T2050).

The T2300E eliminates VT, or virtualization, compared to the T2300, while the T2050 reduces the front-side bus from 667MHz to 533MHz compared to the T2300E, which can be viewed as a "neutered" version of the T2300.

The Pentium Dual-Core T2060 processor has the same frequency and FSB as the T2050, at 1.6GHz and 533MHz

. The only big difference is the L2 cache, where the T2060 is exactly half the size of the T2050, at 1MB, which means it's "neutered again".

T2300 - VT canceled = T2300E - front-side bus down to 533 = T2050 - L2 cache down to 1MB = T2060

T2350, T2130

The same Pentium Duo T2130 can be regarded as a castrated version of the Core Duo T2350, with the same 1.86GHz frequency and 533MHz front-side bus.

T2250, T2080

The Pentium Duo T2080 can be seen as a neutered version of the Core Duo T2250, with the same 1.73GHz main frequency and 533MHz front-end bus as the T2250, except for the 1M L2 cache.

The Pentium Duo T2080 is a neutered version of the Core Duo T2250, with the same 1.73GHz main frequency and 533MHz front-end bus as the T2250. >Core 2 (Duo) named 7X00 (single digit for the new Core 2 cores, i.e., the CPU of Xun4), 5X00, 5X50 (new Core 2 cores), e.g., 7100, 5500, 5200;

Core (Duo) named 2X00, 2X50, e.g., 2050, 2300;

Pentium (Duo) naming rules are: The 32-bit 2060, 2080 (ending with an even number + 0)/and the 2310 series now upgraded to 64-bit can probably be called Pentium II

The difference is mainly that Core 2 (Duo) and Pentium II are 64-bit, Core and Pentium I are 32-bit.

Core 2 (Duo) in the 5X00 is 7X00 (dual-core) cache neuter version, 5X50 is 7X00 (singular) cache neuter version, 5200, 5300 is 5500, etc. based on the further neuter FSB version:

7X00 (singular, 7100, 7300 ...) is 800MHZ FSB, 4MB L2 cache,

7X00 (even number, 7200, 7400...) is 667MHZ FSB, 4MB L2 cache,

5X50 (5550, 5650) is 800MHZ FSB, 2MB L2 cache,

5X00 (5500, 5600) is 667MHZ FSB, 2MB L2 cache,

5X00 (5200, 5300) is 533MHZ FSB, 2MB L2 cache,

similarly, Core (Duo) 2X50 is a FSB-neutralized version of 2X00, and Pentium (Duo) is a cache-neutralized version of Core (Duo) 2X50:

2X00 is a 667MHZ FSB, 2MB L2 cache,

2X50 is a 533MHZ FSB, 2MB L2 cache,<

Pentium (dual-core) L2 cache is only 1MB, FSB is only 533MHZ.

Generally speaking, now intel's Core series is directly facing the mid-range and high-end machines, and would rather come out with new varieties to reduce the cost and computing power, but also not to depress the price of Core.

In a word, the current Pentium series is based on the Core architecture series on the shrunken version of the core and process and Core is exactly the same, so the heat is not too big, just scaled down the front-side bus, the L2 cache has been simplified to 1M. what is the difference between the Pentium D Dual Core and Core Dual Core? Why is the former about 2.8G and the latter about 1.8G?Answer ListThe Athlon X2 Dual-Core processor from AMD uses the AMD K8 architecture, which has the advantage of low power consumption, high execution efficiency, and integrated memory controllers in hardware, and thus responds to more... What is the difference between a Pentium Duo and a Core Duo? Why is the former about 2.8G and the latter about 1.8G?AMD's Athlon X2 Dual-Core processor uses the AMD K8 architecture, which has the advantage of low power consumption, high execution efficiency, and integrated memory controllers in hardware, resulting in a faster response. It also uses the same exclusive use of L2 cache as the PD dual-core, so it's not unusual for the X2 to beat the PD in performance. Inter's PD820 and PD915 series of dual-core processors are based on Intel's netburst architecture, which is characterized by a high mainframe frequency, and the PD dual-core processors use an exclusive L2 cache, which means that each core can only use a fixed amount of L2 cache. (This is a clear difference from the latest coro architecture, which withholds meat for ****-exclusive L2 cache). For the understanding of the size of the L2 cache, generally speaking, the larger the L2 cache, the better the performance. netburst architecture pipeline for 31 levels, this design is very effective against large data tasks, but against small data volume of simple tasks, the design of the ultra-long pipeline there will be a large delay, the number of instructions processed in a single cycle is limited, the efficiency is not high. Therefore, the PD Duo was replaced by the later Core 2 Duo processor because of its architectural flaws and did not wait for its full popularity.Inter's Core 2 Duo processor uses Intel's new architecture, Conroe, which is much better than the Pentium D's Netburst architecture. PD's pipeline architecture is 31 levels, while Core's is only 14 levels, the shorter the pipeline, the smaller the latency the faster the speed. Coupled with Core's use of *** Enjoy L2 cache, reducing the use of the front-side bus for data exchange, more efficient Core Core is Intel's new generation of dual-core CPUs, now including dual-core and quad-core processors! Core is revolutionary for the development of processors, with more powerful performance than any previous processor update. Pentium D is also known as the Pentium 4 8/9 series. It is a desktop dual-core processor with full 64-bit support.

The so-called "fake" is because: PD's two core cache did not *** enjoy out, as well as the frame way reason, the two box heart as if the "North-South Bridge" as not responding to each other, greatly affecting the performance, so the AMD joke for the "The newest addition to the lineup is a new, more powerful, and more powerful, dual-core processor.
