Bounce for more than a year later, Intel has recently released the core code Broadwell of the fifth daikurui i3/i5/I7 series of chips. First published models are oriented thin notebooks, one machine, and is a dual-core version, whereas for high performance notebooks and desktop models to wait for years.
Broadwell is Tick-Tock strategy for Intel since 2006 the results of the latest generation. Tick-Tock is the annual alternate update CPU micro-architecture and manufacturing processes, to ensure the absolute advantage of Intel in the PC industry.
06 to date, Intel has three upgraded micro-architectures, four-generation manufacturing process. Broadwell is a process improvement compared with the ascendants Haswell 22nm technology evolved to 14nm,CPU the core is the same. This generation of CPU plans released in the first quarter of 2014, but because the factory upgrade progress, and only small shipments until September 2014 Intel ultra-low power version of Broadwell--Core m; Broadwell has been dragged into the mainstream-oriented platform to come this year.
Intel consumer grade mainstream CPU performance has been there for years without much progress. Even compared to the 08 Nehalem architecture, the latest generation of single core Broadwell is only 30%-50% performance increase with frequency. Although a lot of people to blame this phenomenon on competitor Intel AMD's Poor Performance lost across the forward momentum, but the underlying causes are actually micro-processor research and development industry, there are bottlenecks, academia or industry are difficult to attain a higher frequency performance with faster clock speed. Because mainstream consumer-level applications difficult to optimizations for multicore, increasing the number of cores that road to nowhere. So we see Intel are replaced every year, but no new chips on the performance of the past much better than older versions of the scene. This release new chips and corresponding to the same frequency performance compared to previous generation almost unchanged, disappointed many fans.
Since the CPU performance to improve, Intel will focus on power control and improved GPU. In stepped forward to generations of chips have both significant progress and Broadwell continues the momentum. More than 10 models of the latest all TDP low power version of the 15/28w, carefully comparing with the previous generations we will find new models of initial frequency generally promote some, and idle down even more sharply, and lower power consumption. In contrast generation 4650U I7 5650U, for example, their TDP is 15W, but the former standard frequency 2.2G which is only 1.7G, the former frequency of power-saving States for 600MHZ,TDP9.5w which can only block to 800MHZ,TDP 11.5W.
Only parameters are also not 14nm used a new generation of CPU processing power. Laptop cooling capacity is always enough, while Intel's chips generally have Turbo Boost dynamic upsampling function, but is often constrained by its heat and can only work for a short time, machine temperature slightly higher CPU will drop sharply. Next-generation core after a technology upgrade at a high frequency to work longer hours, warming significantly slower than previous generations of the system platform. In addition, the idle energy consumption of the new platform will lower, would bring more battery life.
Upgrade the GPU portion of the fifth daikurui, high middle and low GPU unit models are 20% more than previous generations, also improved. Comprehensive new series corresponding to the 3D performance than the previous generation models increased by 30% or so. With no progress compared to the CPU part of the increase has been very good.
Intel product has always been messy, especially laptop chip complex of the naming of the product line, is also easily confused. This new release is a low-power version of the chip, look to confuse each other's differences. But after careful analysis of these models will find that their CPU Basic only the difference frequency due to thin and light notebook cooling generally poor, tucked high frequency core of little practical significance. Rui-3.2G I7 5650U loaded with more than 10 seconds will block to 2G, and no core i3 5010U is a result. Count on buying expensive I7 models have a better performance of consumers don't want to waste money, might as well choose a cooling ability of the machine.
Is a powerful GPU part on the actual user experience. So several chips match Intel GPU for three classes, two close performance gaps between more than 1 time. And matching high-end GPU i3 and matching low-end model I7, it is easy to confuse people. Since the CPU part not much gap, consumers when choosing a machine not only care about the GPU, try to choose a higher-numbered models. HD6000, for instance, is much stronger than the HD5500, but actual price makes no difference, even HD6000 I3 is a lot cheaper than the HD5500 I7.
Overall, fifth daikurui is long overdue, but really limited compared with previous generations improved. Intel did not change consistently high price policy, destined to set off much of the waves of new products. The entire PC industry has entered a period of stagnation, superficial update unable to play the role of booster. Intel may need to reflect on their superior attitude, and if the mainstream PC chips is still a duo that cost hundreds of dollars, sooner or later will be low-cost ARM core devices to catch up with or even replace. Had dominated the Wintel Alliance, another big lead, Microsoft began "turning a new leaf", leaving Intel is running out of time. Louis Vuitton (LV) iPhone 5 Case

Microsoft Surface Pro 3
Surface Pro Tablet and laptop in one is a good idea, on which men don't want Hall under the kitchen's wife? Which tech press want to write the article talks of all business people? Surface and primary Surface Pro Pro 2 (only CPU generation) is neither good tablets, thick, short battery life; it's not a good laptop, small screen, bad keyboard, frame is not flexible. Now, the Surface Pro 3 comes out clear, these problems all solved, Microsoft has always been low-key attitude began to fight back.
