Mô tả sản phẩm: Leadtek NVIDIA Quadro FX 4500 (NVIDIA Quadro FX 4500, 512MB, 256-bit GDDR3 PCI Express)
The NVIDIA Quadro FX 4500 ultra high-end graphics solution shatters performance limits facing CAD, DCC, and scientific applications. Armed with a radically new graphics architecture engineered to address the most demanding challenges, Quadro FX 4500 ultra high-end product by Leadtek delivers up to 33.6GB/s memory bandwidth, 512MB GDDR3 frame buffer memory, 256-bit memory interface and support for two ultra-high resolution (3840 x 2400) digital panels. It is targeted as a high-performance graphics solution for PCI Express workstation systems that delivers unprecedented power and performance capabilities with unmatched features and capabilities for workstation professionals.
The FX 4500 product features a revolutionary new architecture with 2x the geometry and fill rate, 5x the hardware pixel read-back performance and 1.25x the memory bandwidth of previous generation workstation graphics. Implementation of rotated-grid FSAA function introduces far greater sophistication in the multi-sampling pattern, significantly increasing color accuracy and the visual quality of edges and lines.
The NVIDIA Quadro FX 4500 model supports NVIDIA SLI (Scalable Link Interface) -- an innovative new technology that intelligently scales graphics performance through multiple NVIDIA GPUs in a single PCI Express system. SLI scales both geometry and fill rate/pixel shader performance for two GPUs using various methods, including inter and intra-frame scalability algorithms. And depending on the application, NVIDIA SLI can deliver as much as 2x the performance of a single GPU configuration for unparalleled working experiences.
Quadro FX 4500 introduces a new era of graphics image quality at unprecedented performance levels. The Rotated Grid Full-Scene Anti-aliasing (RG FSAA) increases color accuracy and visual quality for edges and lines, reducing “jaggies” while maintaining performance, and sets new standards for image clarity and quality through 32-bit per component floating point. This algorithm solves what has traditionally been a compromise between performance and quality.
PCI Express is a brand new high-performance technology for PCs. By working hand-in-hand with Intel in the development of graphics solutions for this revolutionary new graphics bus architecture, Leadtek and NVIDIA introduce Quadro FX 4500 that enhances your experience and prepares you for the future of computing. With double the bandwidth of the AGP 8X graphics bus, FX 4500’s PCI Express solution delivers a new level of PC performance for graphics and networking. This new bus doubles the bandwidth of AGP 8X delivering over 4 GB/sec. in both upstream and downstream data transfers.
Leadtek Quadro FX 4500 features dual 400 MHz integrated RAMDACs and dual-link DVI part. Some high resolution panels such as Apple’s 30-inch Cinema HD Display require dual link DVI to drive its massive amount of pixels. The 30-inch Cinema Display has a native resolution of 2560 x 1600, which exceeds the bandwidth a single TMDS link can deliver. To support two 30-inch Cinema Displays, you need a special ultra-high end card with two dual-link DVI ports such as FX 4500. It supports a maximum 2048 × 1536 × 32bpp at 85Hz resolution over VGA port and a 3840 × 2400 × 32bpp resolution over digital port. The Dual-link TMDS transmitters support ultra-high-resolution panels which result in amazing image quality producing detailed photorealistic images.
