Intel Sandy Bridge processors deliver more performance than Nehalem processors using less energy in a more manageable way. This speed-up is the result of various architectural improvements in the core. These processors provide more firepower to play games and 3D contents. This is said to be the first consumer processor made by Intel that has a fully integrated graphics unit and modular structure to enhance performance in all sorts of ways.

DRAM modules and its significance

DRAM stands for dynamic random access memory. DRAM devices usually use capacitor charges on an integrated circuit to store the digital information. The capacitor must me recharged frequently, so that the information is retained. So, DRAM is a volatile memory.

DRAMs are generally manufactured in different formats. Some of them are DIP which is Dual in-line package and SIPP, SIMM, DIMM and many other formats. The RAM memory cards used in present day computers are a type of DRAM in DIMM format. DDR3, DDR2 , DDR and SDRAM are synchronous DRAM modules.

DRAM is made to be in sync with the clock of system bus. DRAM chips may contain information after the power supply is removed for longer time at lower temperatures. Under proper conditions, a DRAM is found to contain data for several minutes after power off. This data can be used to break in to encrypted systems and steal private information.

Memory Cards and their use

Memory Cards are NAND Flash memory type chips that are available in extremely small dimensions. There are different classes of memory cards based upon the size and speed of the memory. The memory cards are commonly used in many devices like mobile phones, laptops, portable music players, digital cameras and camcorders and many video game consoles.

Some of the different types of memory cards include sd memory cards, sdhc memory card, MMC etc. SD stands for secure digital and is a standard memory card module for use in most of the mobile phones and laptop computers.

MicroSD is a miniature variant of SD cards and SDHC is a high speed memory card for use in demanding devices like digital SLR cameras which have the need to store a large amount of data in a short amount of time.

There are different classes of SD cards according to the read or write speeds. Solid state memory card devices are also used in many gaming consoles which allow for the graphic games to initiate. There are card readers available for reading the memory card data in a personal computer.

What difference does a good graphics card make?

Graphics CardA graphics card or a video card is basically an expansion device which is used for processing the graphical information which is used for delivering the output images. Many graphic cards offer various functions which include high speed rendering of 3D graphics and also 2D scenes. The graphic card also performs functions like decoding of video content.

Many motherboards have basic graphic cards soldered on to them to perform basic functions like producing the monitor output. Anyways, all the motherboards have expansion slots for connecting the external graphic card or other devices. The onboard graphics processor possesses a very little amount of memory and uses systems RAM to render graphics content. Modern graphic cards have evolved in to gaming devices which enable the processing of high quality 3D graphics to offer a smooth gaming experience.

A graphic card consists mainly of the following components:
Processing Unit: Also known as GPU (Graphics processing unit), this is responsible for all the processing involved in accelerating graphics. These processors are specifically optimized to perform 3D Floating point operations which are basic for 3D and 2D graphics. A GPU is characterized by its clock speed or core speed and the number of pipelines. Latest GPUs are parallel and they have higher processing power than many CPUs.
Memory: This can range from 128 MB to 8 GB in modern graphic cards. This memory is a high speed memory module as the GPU and Other components of graphic card use it. Typically, it can be DDR or GDDR. GDDR is graphics optimized DDR memory and is used in almost all the desktop video cards. DDR memory is used in mobile graphic cards due to the thermal and electrical limitations.
Video BIOS: This is another chip which contains the instructions for the graphic card’s operation. It also has information useful for the system to interact with the graphic card. This part is usually hidden and is different for different type of graphic cards. It determines the clock speed and sometimes also has functionality to overclock the graphic card.
RAMDAC: It stands for Random Access Memory Digital to Analog converter. As the name implies, it converts the digital output in to analog signal for use by output devices. Depending on the number of bits used and the RAMDAC-data-transfer rate, the converter will be able to support different computer-display refresh rates.
A graphic card generally has outputs which contain an analog output and a digital HDMI output. In the current market, AMD acquired ATI and NVIDIA are two world gaints in production of graphic processing units. AMDs Radeon 69XX series are some of the fastest graphic processing units available in the current market.

Why CPUs Need Heat Sinks?

Heat sinks are components that are responsible for transferring heat from a solid material to air or liquid medium. They increase the contact surface area to make heat transfer faster.

Modern computers have CPUs as their heart that processes all the data. Processors become hot very quickly but require cooling to function properly. This is what the heat sinks are for.

Computer hHeat Sinkeat sinks are attached to the processors to collect heat from them and transfer the collected heat to air or liquid media. Fans or thermal cooling solutions are attached to the heat sinks to take the heat away from them so they can provide necessary cooling to the processor.

DDR3 SDRAM and its advantages over previous versions

DDR in DDR3 stands for Double Data Rate. It is the latest memory standard for hispeed SDRAM that we use in our computers. DDR3 is a improved version of DDR2 in many aspects. DDR3 Ram is a type of DRAM. DDR3 shows a lesser power consumption of 30 percent and also a lower operating voltage when compared to DDR2.

Lesser power consumption means less amount of heat generated. So, the cooling needs of DDR3 are less than DDR2. DDR3 Ram is not forward or backward compitable with any type of other RAM as the operating voltages, clock speeds, timing and several other factors.

DDR3 memory has a high bandwidth interface. In addition to all these advantages, DDR3 memory type also provides the facility of having up to 8 Gigabites of memory on board. DDR3 RAM modules have different notch positions to DDR2 to prevent accidental insertion of DDR3 memory in to DDR2 slots.
