Imagine one day in 2011 (sounds like the future, in fact, there is also less than two months), if the store salesman to show you an Intel-based there is no “graphics card” of the computer, but can smoothly run the latest 3D online games and play Blu-ray movie mainstream, be careful not think they are in the flicker, because by that time, a combination of processor, graphics processing units to achieve all this, this new processor R & D, code-named Sandy Bridge (hereinafter referred to as SNB). Although the products from the release next year some time, let us start with the SNB’s five “unique Cheats” began, one by one to decrypt it for everyone.
Intel Core Graphics – 3D smoother more perfect vision
If the previous generation Intel Westmere processor chip from the motherboard GPU Northbridge chip in “move” to the CPU chip in, then the SNB processor GPU is “born” in CPU chip in, we call it seamless integration. Analogy, Westmere’s integrated graphics card is not as independent as to have their own station (memory), even when working memory all the way to go people get information on the station, and then came back treatment work.
As SNB processor “own” the GPU certainly better treatment, it can directly use the shared three-level cache, each core with a direct exchange of data in the cache before the system is not limited to memory. That SNB GPU and CPU as the processor has its own station, which improve performance and reduce power consumption are of great benefit. Of course, the people are, and CPU belong to the “Management”, and then called integrated graphics obviously is inappropriate. Zhao Jun, Intel technology experts mentioned in the official blog SNB Intel graphics processing unit as a “Core Graphics”, referred to as “nuclear obvious.” Core graphics card will also be different from the graphics card, a new category of integrated graphics card. According to foreign media reports, notebooks equipped with Core Graphics can even run smoothly “StarCraft 2.”
SNB processor also designed an innovative high-speed ring Unicom architecture, each core, each cache section, nuclear was the kernel management center, and so can the high-speed bi-directional ring architecture for more efficient data exchange. The SNB ring inside the processor architecture will link the various units, which is the ring of nuclear Unicom was an important node architecture.
Wireless Display (WiDi) – feel free space wireless
If the facial features of the selected one of the most important part, about Jiucheng of people will not hesitate to choose the eyes, because we feel the color of the eyes to observe everything. Then we are justified in our eyes a little better, let it be more clear, more wide viewing screen it? Intel Wireless Display (WiDi) can help us shake off the laptop can only sit in front, his eyes staring at the dozen bear-inch screen, enjoy high-definition video and picture mischievous situation, Intel set off from the vision to use technology to the body of the liberation movement.
Intel’s wireless notebook display technology can be easily or with large-screen HDTV projector wirelessly connected, whether based on network or local hard disk, or a home theater center, all so wonderful and sharing the big screen to easily upgrade to HD! Will be a display technology designed for the Intel wireless adapter to connect to a wireless high-definition TV or projector, and through high-definition graphics technology with Intel and Intel wireless technology, laptops, wireless laptops can be connected to the LCD TV or projector .
Intel wireless display technology for digital audio and video entertainment notebook screen size out of the constraints, high-definition television can be saved in the notebook wonderful movie. Watch the video broadcast network, notebook and computer desk is no longer the only choice, Intel’s wireless technology allows high-definition display true high-definition broadcast network up on the sofa in the living room you can enjoy the daily use of digital television recording high-definition home videos and Internet films and television shows, Let every family member can share the big screen to bring the fun! Connect the projector while the Intel laptop, but also changed the business meeting the speaker must limit the length of the transmission line near the projector situation.
3D Cinema cited Touch technology – realistic image of a “touch” that made
We all know that the 3D games and movies are beginning to of the. Ever since the 3D Blu-ray Disc, DVD, you talk to people to show off, red and blue color behind the times the three-dimensional movie, 1920×1080 Full HD, Blu-ray full-color 3D IMAX 3D theater is really comparable to the film source. With the passage of time, we can immediately enjoy the visual feast at home, because the processor to the SNB. Before the processor or graphics can only cope with a normal Blu-ray movie, while playing a 3D Blu-ray movie that white is the high rate at the same time playing two Blu-ray movies, which is none other than non-SNB.
Why? SNB processor because there is a media processor, responsible for video decoding, encoding. The new hardware-accelerated decode engine, the entire video pipeline is decoded by a fixed function unit, and now just the opposite, SNB video processor power consumption can be cut in half the time. This is equivalent to SNB processor dedicated to video decoding, encoding formed a “task group” dedicated to 3D Blu-ray movie player such as heavyweight work, and this “group” is a “one-when the hundred”, They only consume the SNB processor core area of 3 mm2.
AVX instruction set – double-double performance of the bandwidth
SNB bring about a new Intel processor instruction extensions AVX, the calculation unit from the previous 128-bit multiplier to the current 256-bit, so in theory SNB floating point performance processor cores to 2 times. AVX is not the x86 CPU (SSE) instruction set extensions, but can achieve higher efficiency, but also, and CPU hardware compatibility is better, and also has enough room for expansion. This technique is like a ring road overpass, in the same area of the width of a volley on the more repair a viaduct, making the traffic flow per unit time (data) more.
Of course, the AVX ,256-bit instruction set also represents the instruction encoding format changes. Prefix to extend the head to increase possible, and enhanced the first part of the instruction register also increased Prefix as possible. It’s like if a person is a long stay in a small place, because there is no reference, then the long period of time in which he would not feel the space is very small. But if you put a long-dwelling people inside their nest to the open, then he will feel very empty.
Turbo Boost 2.0 – Intelligent perfect performance upgrade
As we all know, the first generation of Turbo Boost technology allows the processor “overclocking” is determined by how high TDP power, which is like a conservative think his strength can only support a fixed number of steps on him, and then another job on not to go. But the fact that he can support his physical strength to climb higher level, a good coach if he believes himself to be on the strength of a higher level, he can climb even higher according to their own physical strength on the steps. This is the Intel Turbo Boost 2.0, it will be active in a short time to allow the calculation of core speed, cooling power than the TDP or more, the control unit keeps track of free space heat (especially when the system is idle), the system calculates the volume of when the speed beyond the TDP. Processor idle longer able to go beyond the longer TDP, but no more than 25 seconds. In stability, the control unit will not allow the processor than the temperature limit.
Turbo Boost 2.0 another big step: SNB graphics processor core can independently Dynamic Acceleration, up to amazing 1.35GHz. If the software requires more CPU resources when not many graphics operations, then the CPU will accelerate, unit will slow down and vice versa. In fact, the first generation of Turbo Boost Technology can already do this on a laptop, while the desktop computer in the Turbo Boost 2.0 technology to do this.blog
For various reasons, we can not know the current performance of SNB in terms of specific performance benchmarks, but according to many foreign media player evaluation results and evaluation forums posted, with a super hot recently to describe its performance, is too “to force” again! And most everyone’s attention and expectations of the visual characteristics, how powerful, can answer one by one until announced product release.
