Why Intel 14nm Broadwell is revolutionary
|
Broadwell is the next generation of Intel processors after Haswell. According to Intel's plan, we will see Broadwell series processors gradually log on to mobile and desktop platforms in the next 18 months. Although Haswell has not yet been fully popularized, it is time to learn about Broadwell as the fifth generation product. Let's take a look at what aspects of Broadwell have been upgraded? Tick-Tock The upgrade cycle of Intel processor products is generally 18 months, but each upgrade is not a complete product replacement. Since 2007, Intel has adopted Tick-Tock as its chip technology development strategy model, which is what we call "process year-architecture year". The process year refers to the year when Intel will launch a processor with a smaller core area and a more advanced process, while the architecture year refers to the launch of a processor with a new architecture. Generally speaking, process upgrades will give the processor a better power consumption performance, but the performance improvement is not obvious, such as Broadwell. The emergence of Broadwell represents the progress of Intel's processor manufacturing process, which is to be more specific. It is a slimming down of the predecessor Haswell. Process upgrade Speaking of "slimming down", how small is Broadwell? In fact, the "small" mentioned here does not refer to the size of the chip, but the size of the transistor. Haswell uses 22nm transistors, while the size of the transistors on Broadwell is reduced to 14nm. You should know that the transistor size of the first-generation Core processor is 65nm. Intel's technological progress in the past 8 years can be seen. If you want to feel how big the transistor is, pull out a hair and feel the thickness. That is the thickness of 90,000 transistors. It is through the cooperation of hundreds of millions of transistors that the processor has achieved such complex functions of terminal equipment. Power consumption According to Intel, Broadwell reduces power consumption by about 30% compared to Haswell, and the performance has also been slightly improved. These improvements are easy to understand even for ordinary consumers. In fact, Haswell has made great progress in power consumption compared to the third-generation processor Ivy Bridge, which has greatly improved the battery life of Windows notebooks and Macbooks, and made ultrabooks possible. What you should know about Broadwell: It may bring 15 hours of battery life. For example, the web browsing battery life of the 2013 13-inch MacBook Air equipped with Ivy Bridge series processors is 7 hours, while the 2013 13-inch Macbook Air has improved the performance to an amazing 12 hours, which is inseparable from the excellent energy consumption performance of Haswell. If Broadwell can really reduce the power consumption by 30% based on Haswell, then the battery life of this year's new Macbook Air is likely to be 15 hours, even exceeding most tablets on the market. Why is Broadwell revolutionary? The extremely low power consumption not only brings ultra-long battery life, but also the saved power can be allocated to other parts, such as high-resolution displays. Although the screen technology of smartphones and tablets has made a qualitative leap in recent years, the screen of laptops has lagged far behind in both software and hardware. One of the reasons is that the high-resolution screen consumes more power, which in turn has a greater impact on the overall power consumption of the device, but the emergence of Broadwell may change this situation. It was previously reported that Apple will launch a Macbook Air with a Retina screen in the second half of the year, and Broadwell will be one of the decisive factors for upgrading this type of ultra-thin notebook to a high-definition screen. Integrated graphics performance In addition to the upgrade of the computing core, the integrated graphics performance of the Broadwell series will also be improved. Intel said that the performance of Broadwell's integrated graphics core can basically match the current mainstream independent graphics cards. Like Haswell, there is a large gap in the performance of integrated graphics cards of different versions of Broadwell processors. According to news from CPU World, Broadwell's integrated graphics cards have three models: HD 5500, HD 6000 and iris HD 6100 to widen the gap. It is worth mentioning that Broadwell's integrated graphics card still uses the Haswell architecture, but the number of processing units has increased by 20%. In addition, considering that the performance of integrated graphics cards is getting stronger and stronger, the market for mid- and low-end independent graphics cards will be further compressed, and perhaps the entire graphics card market will change as a result. When will Broadwell arrive? It is reported that Intel will start to provide Broadwell series processors to OEM manufacturers in early 2015, including the Core M series specially launched for fanless two-in-one devices. Although all Broadwell processors will not be launched at the same time, there will be three main versions in the early stage of mass production, which should belong to the Y, U and H series respectively. The Y series is designed for ultra-low voltage devices. Due to the extremely low heat generation, the device can even adopt a passive cooling design without a fan, but in terms of performance, the Y series can only meet the needs of light users. Next is the most widely used low-voltage U series. This series of processors will be mainly used in new ultrabooks and the next generation of Macbooks. The power consumption and performance are relatively balanced and can handle general photo and video editing. Finally, the H series is mainly launched for desktop devices. Since there is no need to consider power consumption, the performance of the H series is very powerful, which is perfect for enthusiasts. It should be noted that due to technical, production capacity and cost reasons, Broadwell will not be popularized quickly in the early stage of its launch and the price is high. It is recommended that you wait for a while before upgrading. Post-Broadwell era There is no doubt that there will be a new successor after Broadwell, and it is Skylake. According to the previously mentioned "process year - architecture year" technology roadmap, Skylake's architecture will be redesigned, but will continue to use the 14nm process. It is reported that Skylake's integrated graphics performance will be more than 150% of Broadwell, which is quite exciting, but before that, we should patiently wait for the arrival of Broadwell and Retina version of Macbook Air!
