"Sandy Bridge" is that it is an Intel project code name for a new processor architecture. In Sandy Bridge, the CPU and graphics processing unit (GPU) were combined in one 32 nanometer piece of silicon. Sandy Bridge technology is a part of the 2nd generation Intel Core processors and is a completely new microarchitecture. The new microarchitecture will enable faster 3D and video processing speeds, as well as increased performance for gaming, HD videos, 3D graphics. The chip also requires fewer buses which translates into faster processing speed.

There will be a wide variety of different processor types introduced into the mobile, desktop, server, embedded computing market segments starting in early. The way CPU die has been re-structure in the Sandy Bridge architecture to give a tighter integration between the memory interface and processing.

Launched

Intel Sandy Bridge was launched on January 5th 2011 at the Consumer Electronics Show in Las Vegas. When the launch is made, almost manufacturer in the world has come up with Sandy Bridge. HP, Dell, Apple, Sony, Acer, Lenovo and Toshiba have all announced that they are up for it. Although Intel had refused to name a launch date, the smart money was on it being at Consumer Electronics Show.

Visual computing capabilities in Sandy Bridge

The Sandy Bridge architecture provides multiple processing with 8 cores in the processor version. There is also separate graphics core and a new processor feature called Intel AVX.

AVX stands for Advanced Vector Extensions.

And also it improves the floating point computational speed.

Computational speed means it will have a minute changes in the processing speed. Increasing the size of the vector width about 256 bits so that it will increases the store operations also helps the AVX perform well. All of this gets combined with a new capability of applying Intel Turbo Boost Technology with all cores. So that it will boost the high- definition videos and 3D animation or motion picture performance in video processing applications.

One of the major concern about the Sandy Bridge is that the ability of using the new processor architecture to support multiple video and 3D graphic interfaces directly out of the processor.

New innovation in Sandy Bridge Technology

Intel has beaten AMD to be the first CPU company to integrate a GPU into the silicon dye of an x86 processor.

It managed to integrate a GPU into the processor packaging for its based core i3 and core i5 CPUs.

The Intel GPU is update from previous Intel HD graphics which improved the gaming speed, video playback clarity.

The main aspect regarding the graphics unit is that it shares the last-level cache (LLC) of the entire dye.

Using the level 2 and 3 caches, any CPU can reserve any amount it requires, therefore making that cache work more effective.

The layout of a p67 motherboard requires one of the following aspect to overlock the Sandy Bridge CPU.

The inclusion of a GPU into CPU very tightly packed. And the ring bus controller allows GPU to have high performance and efficiency.

All the buses of LGA1155 motherboard are controlled through a single lock generator. This is may not be significant which means the overlocking through the base lock is limited.

Features of Sandy Bridge Technology

The features which are included in the sandy bridge technology are

It has a more powerful graphics which enables the micro architecture to have more speed for the 3D and video processing

New hardware-based media accelerators and graphics execution unites deliver superior performance for gaming, HD video content, and 3D graphics.

This technology will help the user to enjoy the HD content and web experiences.

Redesigning and Reprogramming

While redesigning the CPU with the Sandy Bridge Technology. If there is any problem in the memory while processing. The problem will be solved by the micro- operation processing and in will enable the memory to have less overlapping of work.

Unification

It is a first time that in Intel processor using Sandy Bridge which combined the memory, PCI express, video controllers into a single dye. So, these system communicate with each other all processing cores, and also increases the speeds and efficiency by way of a ring-based interconnect.

Scalability

The ring-based interconnect has four fully pipelined rings, and scale as the number of cores and cache size will be increase. So that all kinds of systems based on the technology from budget laptops to high-end. Which says that scalability will have a level from low price user to high price user of the laptops and desktops.

Rethought Uncore

A new system is completely integrated with the ring, and it gives power and thermal management services for the PCIe and DDR controllers, and also it allows video and media processing systems to operate at higher bandwidths and with lower latency.

Newer and Better Graphics

Directx 10.1 will be a video support on Sandy Bridge Processors, but Sandy Bridge sports completely redesigned and subsystem media for Intel. So that it will increase the performance in everyday computing as that as specialized tasks like video editing and transcoding is available. Sandy Bridge is built-in support for a wide variety of popular video codecs, as well as accelerators for mostly used filters like scaling and removing noise.

Boosted turbo boost

In this technology they increase the performance of the cores by turning off the cores which are not being used by this method the turbo boost has more effect on the thermal realties of the micro operation processor. In turbo boost processing them target the speed of about 25 seconds per second and then they bring it down to a safe limit within the turbo boost operation can operate.

Upgrades required

In this technology the major disadvantage is the CPU is not compactable with the LGA1156 socket. Because the require new motherboards with a new LGA1155 socket.

Heat is less on the CPU

Because of the new sandy bridge processor there is less heat in the output .this ensures that desktop system requires a smaller fan for the heat to sink. The new fan heat sink is half the size of the fan used in the Westmere and Clarkdale core like i3, Core i5, and Core i7 CPUs.

Very Limited Bus Speed Overclocking On Sandy Bridge

The bus speed plays a major role on the power users who generally overlock the processor. The fundamental formula for over locking the processor is

CPU Clock = CPU Bus Speed x Multiplier

in the last generation processor the bus speed is called as the base clock it has a range from the default 133MHz, up to 220Mhz with the extreme cooling. As the sandy bridge processor is available the base lock is not being used. Because the conversation range on the base lock on the sandy bridge processor is very limited.

DRAM Speed limited settings

DRAM is the most common kind of random access memory for personal computers and workstations. DRAM is dynamic in that, unlike Static RAM, it needs to have its storage cells refreshed or given a new electronic charge every few milliseconds. DRAM Speed automatic range setting on the Sandy Bridge also be limited in accordance with its base clock which range in Sandy Bridge base clock alteration is very limited.

DRAM Speed = Multiplier Base Clock * DRAM

Benefits of the Sandy Bridge

Speed

Computers equipped with new Intel 2nd generation core i processors are typically significantly faster than their predecessors.

Game play

Because of CPU and GPU in same die. So that the gamers can play with high graphics effect. This chip can switch between the integrated graphics and video card depending on use in the laptops.

Size

In the Sandy Bridge chip the CPU and GPU on a same die, this creates a smaller package which gives a thinner and lighter laptops. Battery life also increases as the laptop size decreases and the overall energy consumption becomes less.

Video Editing

For the video editor, Sandy Bridge chips offer high performance using Intel's quick synchronization video that is built into the processor. You can encode the video using even high-end NVIDIA graphics cards. It has excellent solution for video editing.

Multimedia

Because of the Sandy Bridge processor, it has a high definition display and Blu-ray player. It gives more expanded imagery in a laptop. The chips also support for playback of Blu-ray stereo 3D content with HDMI 1.4a. It gives sharper image of the video.

Conclusion

Because of this new invention of the sandy bridge technology there is a improved graphics it improves the clarity and efficiency while gaming, and watching video. It improves 3D effects which gives real virtual effect to the user. By using the sandy bridge micro processor the task can be completed very fast, and their won't be any overlapping in the memory.
