XFX RADEON HD 4770
"XFX Radeon HD 4770 review also featuring Gainward Radeon HD 4850. XFX Radeon HD 4770 has a 17% higher clock speed, 38% higher memory speed but 20% less Pixel Shaders compared to Gainward Radeon HD 4850. XFX Radeon HD 4770 does have a disadvantage which is the 128Bit Memory Interface which is half that of Gainward Radeon HD 4850. How will this effect XFX Radeon HD 4770's performance?"
"Powered by the latest 40nm manufacturing processing technology, XFX ATI Radeon HD 4770 Graphics Card is truly lethal. Representing an industry milestone in the advancement in gaming performance, it is capable of widespread destruction with faster frame rates, higher resolutions and unparalleled speed."
"GDDR5 memory arms users with twice the data per pin at 750MHz than equally equipped GDDR3 cards. The brute processing power delivered by XFX ATI Radeon HD 4770 ensures exceptional performance for physics, artificial intelligence, dual-stream picture-in-picture computing and ray tracing calculations."
"Unparalleled 24x custom filter anti-aliasing (CFAA) and high performance anisotropic filtering delivers unmatched realism, smoothing jagged edges and creating amazingly realistic graphics. And ATI CrossFireX technology seamlessly scales rigs to quad mode."
"Engineered to maximize the latest DirectX® 10.1 games, XFX ATI Radeon HD 4770 delivers outstanding performance for today’s and tomorrow’s games. ATI Stream Technology enables XFX ATI Radeon HD 4770 to tackle the most GPU-punishing tasks like video transcoding with amazing speed. No matter how you measure it, XFX ATI Radeon 4770 graphics card does it all faster, better and deadlier than anything on the market."
XFX RADEON HD 4770 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."
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. Its advanced memory management technology makes more efficient use of all the available memory in computers with PCI Express® technology. Graphics applications can share system memory and use fast on-board memory for real-time processing between the graphics card and the computer’s memory. This ultimately increases the affordability of ATI’s Radeon graphics technology."
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."
