CUDA
NVIDIA® CUDA™ is a general purpose parallel computing architecture that leverages the parallel compute engine in NVIDIA graphics processing units (GPUs) to solve many complex computational problems in a fraction of the time required on a CPU. It includes the CUDA Instruction Set Architecture (ISA) and the parallel compute engine in the GPU.
PhysX
NVIDIA® PhysX® technology delivers real-time, hyper-realistic physical and environmental gaming effects in the games you want to play today and tomorrow. “Canned” reactions are a thing of the past – PhysX-powered games comes to life with blazing explosions, reactive debris, realistic water, and lifelike character motion.
Unified Shader Architecture
The Unified processor dynamic load balancing and resource allocation for vertex shader, geometry shader, and pixel shader.
SM4.0
Shader Model 4.0 can reduce a great much work load for the programmers.The maximum instruction from 512 instructions under Shader Model 3.0 up to 64,000;the number of temporary registers available also increases, up to 4,096 from 32,and the numbers of textures available is also up to 128.
1G
Based on 1G GDDR memory! 1G memory provide more storage space,assure it will not use the memory of the system,so rendering pictures is fast and efficiently.
HDMI
HDMI (High-Definition Multimedia Interface) is the newest interface for audiovisual equipment such as high-definition television and home theater systems. With 19 wires wrapped in a single cable that resembles a USB wire, HDMI is able to carry a bandwidth of 5 Gbps (gigabits per second). This and several other factors make HDMI much more desirable than its predecessors, component video, S-Video and composite video.
HDR
HDR stands for high dynamic range. In photography this technique allows you to increase the dynamic range of a image. Neither digital nor film photos can hold all of the light available in a scene. Also, current displays can only show a small range of color/light range, which makes displaying HDR images impractical for most uses.
OpenGL
Suppors OpenGL OpenGL (Open Graphics Library) is the computer industry's standard application program interface (API) for defining 2-D and 3-D graphic images.
GDDR2
Uses GDDR2 memory GDDR2 is under the "4 bit Prefetch" architecture,it is twice times than DDR prefetch speed.The voltage lowered from 2.5V to 1.8V. This improves power consumption and heat generation, as well as enabling more dense memory configurations for higher capacities.
H.264 HD
Standard HG.264 Video Codec H.264 delivers stunning quality at remarkably low data rates. Ratified as part of the MPEG-4 standard (MPEG-4 Part 10), this ultra-efficient technology gives you excellent results across a broad range of bandwidths, from 3G for mobile devices to iChat AV for video conferencing to HD for broadcast and DVD.
PCI-E X16
PCI Express x16 graphics interface PCI Express x16 is a new graphics interface,based on serial technology performance and a high bandwidth in a point-to-point link. Bandwidth transfer rate is up to 4GB/S,that is about twice of the AGP8X.
