AMD RADEON HD 6900 SERIES DRIVER
Those who are looking to have multiple displays from different vendors should be happy to hear that the AMD Radeon HD and include support for DisplayPort 1. AMD's announcement of its new cards comes just a couple months after the company waged a public battle with its top competitor, Nvidia, over GPU performance.
AMD releases game changing Radeon HD 6900 series GPUs
Back in Octoberthe companies debated which product--Nvidia's or AMD's--delivered the best benchmark performance on video game H. Nvidia first claimed to have stronger benchmarks than AMD's option, which caused AMD to say that Nvidia's benchmark announcement was an "attempt by our competitor to negatively influence [press] reviews" of the AMD Radeon HD series. Nvidia then followed that up with a price drop and comparisons with AMD products, which led AMD to claim that the price cuts were "temporary. At almost square millimeters, the GPU powering AMD's new graphics cards is the largest the company has produced in a long time, but it's still about AMD Radeon HD 6900 Series percent smaller than the GPU in Nvidia's latest cards.
AMD Radeon HD Series Network World
It AMD Radeon HD 6900 Series a lot of texturing power and high clock speeds, but fewer render back-ends than Nvidia's cards have. Note, too, the discrepancy between the numbers of shader units for the AMD and Nvidia cards in the chart above; that discrepancy exists because the numbers are not directly comparable. An Nvidia shader unit is also larger, and therefore not as many of them are present in the GPU.
AMD Radeon HD 6900 Series Nvidia shader unit is also larger, and therefore not as many of them are present in the GPU. The chip features two "front-end" graphics engines, with two thread dispatch processors, two geometry tessellation units, and two vertex processing engines. This design should dramatically improve performance in geometry-intensive applications, particularly those that have a lot of tessellation. Tessellation is a DirectX 11 feature that breaks up large polygons into lots of smaller polygons, to add detail or to smooth the edges of 3D models.
PowerTune AMD Radeon HD 6900 Series CPUs from Intel and AMD have a "turbo" feature that can crank up the clock speed a bit if the chip happens to be running beneath its rated thermal threshold. The core clock speed is set very high, AMD Radeon HD 6900 Series if the chip starts to run too hot, PowerTune lowers the clock speed in small steps until it's back at a safe level. Most graphics cards have to set the clock speed conservatively for the worst-case scenario of an application that strains the GPU and makes it run especially hot. This will be an interesting function for overclocking enthusiasts to play with, but it has even bigger implications for the future, when this architecture eventually finds its way into AMD's "APUs" combination CPU and GPU.
New antialiasing modes: This post-processing effect antialiases everything AMD Radeon HD 6900 Series the screen, but can make the image appear slightly softer as a result. It's functionally similar to Nvidia's "CSAA" modes in that it adds a set of coverage samples to the usual number of color samples.
This type of antialiasing can improve image quality with a pretty small impact on performance. AMD Radeon HD 6900 Series VLIW4 shader architecture: One of the vector units in each set AMD Radeon HD 6900 Series five could handle special functions such as transcendental operations. Now, each vector unit is a four-way unit, with no special-function unit; if a transcendental operation is called, it instead occupies three of the four units. If all that sounds like a bunch of gobbledygook to you, you're not alone. The gist of it is that it should be easier for the GPU's scheduling hardware to keep all the math-processing units busy, providing for better performance in the same GPU area.
Enhanced geometry features: The Radeon HD series cards feature two graphics engines the front-end processing of the graphics pipeline. That means two tessellation units, two geometry and vertex processing units, and two rasterizers. We still think that the high-end cards based on Nvidia's Fermi architecture, which also boast multiple geometry processing units, should offer somewhat higher overall geometry performance.
GPU computing enhancements: The results are mixed. The Radeon HD series cards are certainly fast, though the doesn't always fare better than the Nvidia.
