When we choose computers, laptops such as Lenovo Y450 battery laptop and computer accessories, we also can hear about Core 2 Duo and Pentium Dual Core. But do you know the difference about them?
Pentium desktop now there are two dual-core, one born before the Core 2 Duo, called the Pentium D, one kind after the birth of the Core 2 Duo, called the Pentium E. Dual-core Pentium D is bad, high-frequency low-energy, power, heat is great, it has been eliminated, it is now unable to buy basic PD (stupid D) a. The Core 2 Duo after the birth, with its excellent performance and low energy, low heat, low power consumption, over clocking and good performance by people of all ages, but suffer from expensive, low-end users to bear, so it launched a series emasculated version of the Core 2 Duo, Intel Pentium gave him the name E, Intel may be one reason why it is called the Pentium series to commemorate the achievements of the past (or Pentium series has long been eliminated), so also is the Core Duo Pentium E 2 low-end series, instead of the last full paragraph of that crappy PD, and the characteristics of the Pentium E Core 2 exactly the same as using the same advanced architecture, only slightly lower frequency and the secondary cache, so performance is slightly worse. On the other hand, it’s also to this division of Intel Core Duo and Pentium boundaries.
Core Duo, Core 2 Duo What’s the difference?
Core Duo is 32-bit, Core 2 Duo is 64-bit literally Core 2 Duo clearly is an upgraded IdeaPad Y450 battery version. What are the differences? First, mobile Core 2 CPU support 64-bit computing model for the future era of computing is faster hardware to provide a solid foundation. High-end 7 series has 4MB two cache than Core only have 2MB of full than doubled! Larger L2 cache means that more powerful multitasking capabilities, processing time will be greatly reduced. Originally Core 2 CPU’s FSB should be 800MHz, but three generations of Centrino platform in order to meet the need, or the same as the Core and 667MHz. Core 2 CPU with EM64T has also joined on the SSE4 instruction set support. Because of the EM64T support enables it to have more memory address space, the future face of memory killer – VISTA operating system will not only ease, but also extend the life cycle of the CPU Core. Of course SSE4 instruction set compared to the Core of the SSE3 instruction set, more emphasis on speed and multimedia handling with multiple optimization.
Today already do not use the CPU frequency of labeling method, and use the difference between letters + digital way. Many of my friends the face of these strange numbers is impossible to start the product, under a simple explanation for all Intel Core and Core 2 CPU in the product number in different ways. Given the current Core 2 CPU only T series and the other two series are not yet born. The following mainly from the T series to start, and we talk about the difference between the two. T2XXX Core CPU are generally encoded form, and Core 2 have T5XXX and T7XXX two series. From the frequency point of Core 2GHz CPU most products are in the following, which are much more Core 2 Duo 2GHz or more. T5XXX series Core 2 Duo is low-end products, the secondary cache and the Core Duo line. T7XXX range of products in more than 2GHz frequency, and secondary cache to 4MB!
Pentium 4 with the core technology is a completely different level of technology of the p4 series CPU is used to process all the data used, corresponding to the display device of the computing process. Then the Pentium D series, which supports Hyper-Threading technology, CPU can be divided to two parts of a multi-program operation. And core series is now dual-core technology, the core 2 multi-task can be completed individually without disturbing each other. But can also simultaneously operate as an independent mission to assist each other. Dual-core technology is probably more than the original level of technology to increase more than two times, that the Pentium family with dual-core series 3.0 1.66 operational gap between the technology gap with independent tasks about 30% of the increase, when the multi-tasking operating will exceed this figure.
CORE2 CORE technology to enhance the technology is, ① is to increase the bus speed, ② is to increase the processing power, the dual-core processing technology together to improve and carry out a dual-core multi-threaded operation.
