By keeping the thread size small the likelihood of each pixel in the same thread running down the same path together is increased, allowing you to achieve parallelism and locality. The X1800 threads consists of small 4x4 blocks of pixels (16 pixels). To do dynamic branching РІР‚СљrightРІР‚Сњ ATi focused on two things. However, if executed improperly, it can increase workload and reduce performance as dynamic branching in pixel shaders generally destroys the parallelism of traditional graphics architectures.

It can provide significant opportunities for performance boosts, such as allowing a large portion of shader code to be skipped. Dynamic branching allows a program to execute different branches depending on calculated values. The second source of inefficiency ATi also improved is in dynamic branching, one of the key features in the PS 3.0 model. The array has a high bandwidth connection to the pixel shader cores to allow quick and seamless switching between threads. ATi states that the pixel shaderР”В¬ore achieves well over 90% utilization in practice with this process.Р”Р„ll temporary threads are known as РІР‚СљcontextРІР‚Сњ and are stored in a multi-ported (allows multiple simultaneous reads and writes) General Purpose Register Array.

If a shader program has reached an instruction that needs a texture result, the scheduler senses that the core has become idle and temporarily suspends the idle thread and assigns the free Pixel Shader Core another thread. With the X1000РІР‚в„ўs Ultra-Threading Dispatch schedule this stall does not occur. This occurred in past generations as the pixel shader core was kept waiting. This produces a stall which can introduce hundreds of cycles of latency. One key source of wasted clock cycles is when a pixel shader requires a texture value which is not readily available (not in texture cache) or the texture result hasnРІР‚в„ўt been calculated. Play book and applied it to the Pixel Shader units. Really what theyРІР‚в„ўve done is taken a page out of the Xenos engineering team Workload into a large number of tasks or threads to be worked on by either the Texture Address Unit/Texture The Ultra-Threaded Pixel Shader Engine is an intelligent scheduler which breaks down pixel

The engine is another component that stresses efficiency in ATiРІР‚в„ўs architecture by hiding latency and avoiding wasted cycles. The key to X1000РІР‚в„ўs pixel shader is their new Ultra-Threaded Pixel Shader Engine. By being РІР‚СљDone RightРІР‚Сњ they stress two features that perform well on their pixel shader architecture flow control and 128-bit (FP32) rendering. In ATiРІР‚в„ўs words their Shader Model 3.0 implementation is РІР‚СљDone RightРІР‚Сњ. Has been a major feature selling point for nVidia that ATi now equals or betters. The search for DirectX 9.0c shouldn't be particularly difficultdesign.ItРІР‚в„ўs been a long time coming and now it has finally arrived, Shader Model 3.0 support from ATi.

Even if the patch for Far Cry were to make it to the public through some hole, you would have to get hold of the special nVidia driver in order to really benefit from the new feature.

In addition, we use a special ForeWare driver version 61.45 provided by nVidia, as earlier drivers do not offer the option of using SM 3.0. To get the SM after To be able to use version 3.0, you naturally need Microsoft's DirectX 9.0c, because in the freely available version 9.0b only the shader model according to version 2.0 is anchored so far.

This one is bursting with useful information regarding nVidia's latest prank, sothat everyone who knows something about the matter should take it to heart. In addition, the colleagues at the 3DCenter wrote a very technical article on the subject of What does a Pixel Shader 3.0 chip do today?. If you want to learn more about the Shader Model 3.0, our launch article for the GeForce 6800 Ultra recommended.
