How much is the Pentium dual-core 2.2G processor T4400 equivalent to the Core 2.0G processor?

Core Duo is divided into two types, Core and Core 2. Core is both 32-bit and Core 2 is 64-bit. From a literal point of view, Core 2 is obviously an upgraded version of Core. What is the difference between them? First of all, the Core 2 CPU supports mobile 64-bit computing mode, providing a solid hardware foundation for the future era of faster computing. The high-end 7 series has a 4MB secondary cache, which is fully twice as high as the Core which only has 2MB! A larger L2 cache means more powerful multitasking capabilities, and processing time will be greatly shortened. Originally, the front-side bus of the Core 2 CPU should use 800MHz, but in order to adapt to the needs of the Centrino third-generation platform, it is still the same as the Core 667MHz. Core 2 CPU also adds support for EM64T and SSE4 instruction sets. Since the support for EM64T allows it to have a larger memory addressing space, it will not only be able to face the memory killer-VISTA operating system in the future, but also extend the life cycle of the Core CPU. Of course, compared to Core's SSE3 instruction set, the SSE4 instruction set puts more emphasis on multimedia processing speed and has many optimizations. Now there are two dual-cores in the Pentium series of desktop computers. One was born before Core 2 and is called Pentium D. This kind was born after Core 2 and Pentium E. The Pentium D is a crappy dual-core, with high frequency and low energy, and consumes a lot of power and heat, so it has been eliminated. It is basically impossible to buy PD now. After the birth of Core 2, it has been favored by everyone for its excellent performance, low frequency, high energy, low heat generation, low power consumption, and good overclocking performance. However, it is too expensive for low-end users to afford, so it launched a The series castrated version of Core 2, but Intel named it Pentium E. The reason why Intel named it that way may be to commemorate the past achievements of the Pentium series (otherwise the Pentium series would have been eliminated long ago), so Pentium E is also the Core. The low-end series of Pentium 2 completely replaces the crappy PDs of the past. The features of Pentium E are exactly the same as those of Core 2, because it uses the same advanced architecture, but the main frequency and secondary cache are slightly lower, so the performance is slightly worse. On the other hand, Intel also wants to use this to divide the boundaries between Core and Pentium. When choosing a notebook, the CPU is the top priority, which is directly related to the computing speed and the performance of the entire notebook.

In the notebook market now, the main products are AMD and INTEL. Since the end of 2006 to the beginning of 2007, AMD Continuously launched a series of dual-core products, seizing the mid-to-low-end notebook market with its low price and good cost performance. However, INTEL was unwilling to lower the price of Core Duo to compete with AMD, so it chose In order to reduce the cost by shrinking the CPU, it competes with AMD in the mid-to-low-end notebook market

We are accustomed to calling the shrunken CPU Pentium dual-core,

the true Core dual-core The targets are: intel core duo and intel core 2 duo, representing Core 1 and Core 2 generations respectively

And the shrunken Pentium dual-core, the target is pentium dual core inside

So buy it At this time, be sure to look at the trademark in the lower right corner of the book to see what it is, otherwise you will be fooled by JS and you won’t know what happened

As for the naming of the Pentium dual-core, I have not yet completely summarized it. Do you think INTEL wants this effect? ??I personally think that the Pentium dual-core usually follows the Core dual-core, and the naming is mainly related to the Core 1 generation that is basically discontinued now.

For example, the shrunken version of Core T2050 is T2060, and the shrunken version of T2250 is T2080

The recently released T2310, although it is branded as T23**, seems to be very close to the T2300. , and it is 10 more than 2300. If you are not familiar with it, you might think it is better than 2300, but it is an upgraded version of 2300

That would be a big mistake

It is just another castrated version to cater to the broad low-end market,

Core dual-core T2300 processor, clocked at 1.66GHz, 2MB L2 cache.

And the T2310 main Frequency 1.46GHz, 1M L2 cache,

The only thing worthy of praise is: 2310 is 64-bit - this was also forced by AMD to combat AMD and the current Vista requirements for 64-bit. It's a helpless move, sacrificing computing power in exchange for the value of 64-bit support...

Let's talk about each generation of u in detail:

I haven't collected any All, because Intel is releasing new products so fast now, with new varieties coming out almost every month. Here is just a brief introduction to tell you, don’t look at it based on the previous level of computing CPUs. The numbers are getting higher and higher. The higher the computing power, the more powerful it is only for the same series, such as the Core series. It is easy to make mistakes if you just jump to conclusions if you are not convinced by Core and Pentium - those who know a little bit about U are better to just look at the parameters

Intel, in order to reduce costs, has derived a variety of different models from one CPU. It is dazzling to see, especially T2XXX, which has more than eleven models:

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

Pentium Dual Core T2130 T2080 T2060, and the newer T2310,

The comparison is as follows:

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

First, the tail No. T2X00, the front-side bus is 667MHz, the second-level cache is 2M, but the main frequency is different,

The main frequency of T2500 is 2.0GHz,

The main frequency of T2400 is 1.83GHz ,

The main frequency of T2300 is 1.66GHz, and other models can be regarded as their derivatives.

Compared with T2450 and T2500, compared with T2350 and T2400, compared with T2250 and T2050 with T2300, the L2 cache is 2M, the front-side bus is reduced from 667MHz to 533MHz, and the main frequency is slightly different (T2450 and T2450 are compared with T2300). Same as T2500, 1.86GHz for T2350, 1.73GHz for T2250, 1.60GHz for T2050).

Compared with T2300, T2300E cancels VT, that is, virtualization technology. Compared with T2300E, T2050 reduces the front-side bus from 667MHz to 533MHz, which can be regarded as a "castrated version" of T2300.

The main frequency and FSB of the Pentium dual-core T2060 processor are the same as those of the T2050, which are also 1.6GHz and 533MHz

. Only the second-level cache has a big difference. In the second-level cache, the T2060 is exactly half of the T2050, only 1MB. This is "castrated again."

T2300-Cancel VT=T2300E-Front-side bus reduced to 533=T2050-Level 2 cache reduced to 1MB=T2060

T2350, T2130

Same Pentium dual-core The T2130 can be seen as another castrated version of the Core dual-core T2350, with the same main frequency of 1.86GHz, the front-side bus is also 533MHz, and the second-level cache is reduced to 1MB.

T2250, T2080

The Pentium dual-core T2080 is regarded as a castrated version of the Core dual-core T2250. In addition to the lower level cache being reduced to 1M, the main frequency and front-end system bus are the same as those of the T2250. The same are 1.73GHz and 533MHz respectively.

Core 2 (dual core) is named 7X00 (the odd number is the new Core 2 core, which is the CPU of Xun 4), 5X00, 5X50 (the new Core 2 core), such as: 7100, 5500, 5200;

Core (dual-core) is named 2X00, 2X50, such as: 2050, 2300;

Pentium (dual-core) naming rules are: 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 main difference is that Core 2 (dual-core) and Pentium II are 64-bit, while Core and Pentium I are 32-bit. of.

The 5X00 in Core 2 (dual core) is a cache-castrated version of 7X00 (even numbers), 5X50 is a cache-castrated version of 7X00 (odd numbers), 5200, 5300 are further castrated FSB based on 5500 and so on. Version:

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

7X00 (even numbers, 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 (dual-core) 2X50 is the FSB castrated version of 2X00, Pentium (dual-core) is Cache-castrated version of Core (dual-core) 2X50:

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

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

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

Generally speaking, the mid-to-high-end machines that Intel's Core series directly faces now would rather introduce new varieties to reduce costs and computing power than lower the price of Cores.

In a word, the current Pentium series is a shrunken version based on the Core architecture series. Its core and process are exactly the same as those of the Core, so the heat generation is not too great. It only reduces the front-side bus and the second-level cache. Simplified to 1M. What is the difference between Pen D Duo and Core Duo? Why is the former about 2.8G and the latter about 1.8G? Answer list AMD's Athlon X2 dual-core processor uses the AMD K8 architecture. The advantages of the K8 architecture are low power consumption, high execution efficiency, and integrated memory control on the hardware. processor, so the response is more... What is the difference between Bend D Duo and 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. The advantages of the K8 architecture are low power consumption, high execution efficiency, and integrated memory controller on the hardware. The result is faster response. And it uses the same exclusive use of the second-level cache as the PD dual-core, so it is normal for X2 to beat PD in performance. Inter's PD820 and PD915 series dual-core processors use Intel's netburst architecture, which is characterized by a higher main frequency. The PD dual-core processor uses an exclusive second-level cache, that is, each core can only use a fixed second-level cache. (This is obviously different from the latest coro architecture, which enjoys the second level cache). Regarding the understanding of the L2 cache size, generally speaking, the larger the L2 cache, the better the performance. The netburst architecture pipeline has 31 levels. This design is very effective for big data tasks. However, when dealing with simple tasks with small amounts of data, the design of the ultra-long pipeline will have a large delay. The number of instructions processed in a single cycle is limited and the efficiency is low. high. Therefore, due to architectural flaws, the PD dual-core was replaced by the later-launched Core 2 dual-core processor before it was fully popularized. Inter's Core 2 Duo processor uses Intel's new architecture Conroe, which is much better than Pentium D's Netburst architecture. PD's pipeline architecture is 31 levels, while Core's has only 14 levels. The shorter the pipeline, the faster the delay is.

In addition, Core adopts a shared L2 cache method, which reduces the use of the front-side bus for data exchange and is more efficient. Core is Intel's new generation of dual-core CPUs, which now includes dual-core and quad-core processors! Core is revolutionary for the development of processors, and its performance is more powerful than any previous processor upgrade. Pentium D is the product of Pentium 4 8/9 series. It is a desktop dual-core processor that fully supports 64-bit.

The so-called "fake" is because: the two core caches of the PD are not fully shared, and due to the architecture, the two box cores do not communicate with each other like the "North and South Bridges", which greatly affects the performance. , so it was joked by AMD as "fake dual-core".
