<b>SLI</b>
NVIDIA SLI technology allows you to intelligently scale graphics performance by combining multiple NVIDIA graphics solutions in a single system with an NVIDIA nForce SLI media and communications processor.This technology delivers up to twice the performance of a single graphics solution.
<b>3D Surround</b>
NVIDIA 3D Surround or NVIDIA 3D Vision Surround technology helps to expand 3D gaming across three 1080p displays, and with the SLI configuration it can deliver the graphics horsepower to drive 750M pixels/second for screen 3 times Full HD 1080p 3D Vision gaming for an incredible 5760x1080 experience.
<b>GDDR5</b>
GDDR5 (Graphics Double Data Rate, version 5) SGRAM is a type of high performance dynamic random- access graphics card memory designed for applications requiring high bandwidth. It is based on DDR3 memory which has double the data lines compared to DDR2 but GDDR5 also has 8 bit wide prefetch buffers like GDDR4.
<b>1G</b>
Video memory is used to hold the information necessary for a graphics card to drive a display device. In modern 3D graphics cards, the video memory may also hold 3D vector data, textures, backbuffers, overlays and GPU programs.For high end graphics cards, 1G to 2G or even more video memory is necessary to delivers all its performance power. For mid-range cards, 512M to 1G is usually enough, while for the entry level cards 256M or less is generally enough for the card performance.
<b>Mini HDMI</b>
A Mini HDMI connector, or Type C of HDMI is defined in the HDMI 1.3 specification , and is intended for portable devices. It is smaller than the normal HDMI (Type A) plug connector (10.42 mm × 2.42 mm) but has the same 1pin configuration.
<b>PCI-E 2.0</b>
PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe or PCI-E, is a computer expansion card standard designed to replace the older PCI, PCI-X, and AGP standards. PCI Express 2.0 specification was released in 2007 and doubled the rate of PCI-E 1.0 to a data rate of 500 MB/s and a transfer rate of 5.0 GT/s.
