XFX RADEON HD 4850 FEATURES
"Through the use of stream processing, computer benefit from the ability to transparently access a large number of 'cores' (or, computational units) on a chip without having to separately manage each and every one of them along with their associated busses, memories, I/O, etc."
"VRAM was typically based on DDR technology. During and after that year, manufacturers moved towards the vastly superior DDR2, GDDR3 and GDDR4."
"The video card will have its own video memory which is called Video RAM or VRAM. The VRAM capacity of most modern video cards range from 128 MB to 2.0 GB."
MICROSOFT DIRECTX SUPPORT
"The standard for PCs and next-generation consoles enables stunning and complex effects for cinematic realism. NVIDIA GPUs offer the most complete implementation of the Shader Model feature set-including vertex texture fetch (VTF)-to ensure top-notch compatibility and performance for all DirectX applications."
"Sometimes known as an active cooling device, a small electrical fan which drives air across a heat sink and as such will generate a small amount of noise. It is more effective than a heat sink alone at cooling."
ATI RADEON HYPERMEMORY
"HyperMemory™ is ATI Radeon’s innovative technology that enables a reduction in the amount of on-board memory on a graphics card without compromising its overall performance."
ATI RADEON POWERPLAY
"Advanced power management technology for optimal performance and power savings. Performance-on-Demand allows you to constantly monitor GPU activity and dynamically adjust clocks and voltage based on user scenarios."
ATI RADEON STREAM TECHNOLOGY
"ATI Radeon Stream technology is a set of advanced hardware and software technologies that enable AMD graphics processors (GPU), working in concert with the system’s central processor (CPU), to accelerate many applications beyond just graphics. This enables better balanced platforms capable of running demanding computing tasks faster than ever."
