VisionTek Products R9 290X 4GB GDDR5 PCI Express Graphics Card (900654) GCN Architecture: A new design for AMD's unified graphics processing and compute cores that allows them to achieve higher utilization for improved performance and efficiency. AMD Eyefinty Technology: Run multiple displays from a single graphics board and expand your gaming field of view across all displays. AMD App Acceleration: AMD App Accelerator creates a co-processing environment in which the compute processing potential in your AMD Radeon Graphics processor works together with the system central processor, to accelerate enabled applications. AMD HD3D Technology: Supports the latest stereoscopic 3D content and display technologies. Play 3D games, watch Blu-ray 3D videos, and edit 3D photos on your 3D monitors, TV, or projector. AMD CrossFire Technology: Multi-GPU support offers superior scalability. Increase your gaming performance up to 2x with AMD CrossFire technology, 2.75x for TriFire configurations, or 3.75x with QuadFire configurations AMD HD Media Accelerator: Assumes rendering responsibility for HD encode (VCE)/decode (MPEG-4 ASP, H.264. MVC, MPEG2, etc.) and conclusively enable superior video playback quality with advanced hardware post-processing algorithms AMD PowerPlay Technology: AMD PowerPlay Technology dynamically adjusts clock speeds in response to GPU load, saving power for just when you need it AMD PowerTune Technology: Maximizes performance under load conditions by dynamically increasing the GPU engine clock to take advantage of unused Thermal Design Power (TDP) headroom. Also allows users to configure their own TDP limit, within a provided range, for even higher performance or more power efficiency.
