Not long ago, in a forum, I stumbled upon a lot of netizens asking questions on the post, saying, "What is the use of atom? What is the use?" In fact, this problem is not difficult, but it is really difficult for students who do not understand. . The atom is the intelatom processor. The Chinese name is intel Atom ultra-low-power processor. It is mainly used in light portable laptops and netbooks and tablet computers that are convenient to carry. The atom is the smallest and lowest power processor in Intel's history. Based on Intel's latest micro-processing architecture, Atom is designed for small devices designed to reduce power consumption while maintaining compatibility with the Core 2 Duo instruction set. The product also supports multi-threaded processing. All of this is integrated on a chip that is less than 25 square millimeters in size and contains 47 million transistors. From the specification point of view, this processor has excellent performance while having ultra-low power consumption. This is definitely a very good choice for users who want low-power consumption at the low end. More importantly, Atom This processor is not only for the mobile platform, even on the desktop platform Atom has a very broad development space. In fact, the Atom processor is what we call "Silverthrone" and "Diamondville". Atom is based on 45nm process and hi-k technology. The product's thermal design power consumption is between 0.6 watts and 2.5 watts, but the processor's frequency can reach 1.8 GHz. The current mainstream Core 2 Duo processor has a thermal design power consumption of 25 watts to 35 watts. Intel introduced Atom based on its understanding of the market. Intel believes there is a demand for low-power and Internet-enabled mobile computer devices (netbooks) and Internet-enabled desktops (nettops), which have seen significant growth over the next few years. The Atom processor caters to the needs of the market. Like Centrino Centrino, Intel also gave the Atom processor a nice Chinese name called "Atom". The Menlow platform that matches it is renamed "Centrino Atom." The advantages of Atom in mobile platforms are more obvious, but Atom still has a very large competitive advantage in desktop products. At the same time, the integration platform based on Intel's own chipset is also an ideal choice. Especially for the office family, ultra-low power consumption and good performance are more fully played. More importantly, Atom's desktop-level products are generally smaller in size and easier to move. The Atom processor has five models: Z500 (800MHz), Z510 (1.1GHz), Z520 (1.33GHz), Z530 (1.6GHz), and Z540 (1.86GHz). In addition to the Z500 and Z510 front side bus is 400MHz, the rest are 533MHz. Although the Z500 has a lower main frequency and only 800MHz, the corresponding power consumption is also the lowest, only 0.65W. The power consumption of the Z510, Z520, and Z530 has risen to 2W, while the Z540 with a frequency up to 1.86GHz has a maximum power consumption of 2.4W. Atom is the lowest energy mobile processor of Inte. It is manufactured in 45nm High-KCMOS process, lead-free and halogen-free package, and has a volume of only 13×14×1.6 (mm). The core area of DIE is controlled below 25mm 2 (7.8×3.1). It has a total of 47 million transistors integrated with 512KB L2 cache, supports SSE3 and SSSE3 instruction sets, supports Intel Virtualization Technology (VT Virtualization Technology), Intel AdvancedThermalManager (Advanced Thermal Management Technology), and ExecuteDisableBit (EDB Anti-Virus) technology. . In terms of performance, Atom is very eye-catching, not only because there is not much loss in performance, but more importantly, the price of Aton is extremely low, and the price after becoming mainstream in the future is likely to be around 200 yuan or even more. Low, coupled with the innate advantages of power consumption, is undoubtedly a very lethal product in the low-end market. Because Atom supports STM Hyper-Threading technology, although it is not as good as the Core 2 architecture of the Celeron 420 processor, Atom will show certain advantages in multi-tasking and multi-threading. I believe it will be popularized in the future. ATom on the road will be very smooth, if there is any regret, it is not compatible with the mainstream LGA775 on the interface.
