Radeon X XT Crossfire - Page 1

With such a large number of threads per "quad", ATI created a very large general purpose register array that is capable of multiple concurrent reads and writes and has a high-bandwidth connection to each shader array. This provides temporary storage necessary to keep the pipelines fed by having work available as much as possible. With chips such as RV and R, where the number of shader units per pipeline triples, the efficiency of pixel shading drops off slightly because these shaders still have the same level of threading resources as the less endowed RV AMD Radeon X1800 XT Graphics R R and R had nearly identical memory controller designs, with the former being a bug AMD Radeon X1800 XT Graphics release designed for higher clock speeds.


R, however, differs with its central controller arbiter that connects to the "memory clients". Around the chip there are two bit ring buses running at the same speed as the DRAM chips, but in opposite directions to reduce latency.


Along these ring buses are 4 "stop" points where data exits the ring and going into or out of the memory chips. There is actually a fifth stop, one that is significantly less complex, designed for the PCI Express interface and video input.

This design allows memory accesses to be far quicker though lower AMD Radeon X1800 XT Graphics by virtue of the smaller distance the signals need to move through the GPU, and by increasing the number of banks per DRAM. Field explanations[ edit ] The headers in the table listed below describe the following: Codename — The internal engineering codename for the GPU. Launch — Date of release for the GPU.

United Kingdom: It, however, is an extremely fun crusade though. A confrontational situation in which opposing factions, forces, views, or opinions converge: Rapid, heated discussion. What we'll be doing today is this: This is especially important in situations where games use the dynamic branching and conditional elements AMD Radeon X1800 XT Graphics in Shader Model 3. The shader dispatch unit, by keeping a lot more shader threads in flight at one time, can simply feed a different shader thread to the pixel pipeline to keep it from stalling and pick up on the other thread when it gets the data it needs.

ATI claims that competing architectures manage threads in very large blocks, which is terribly inefficient when dealing with dynamic-flow-control situations. In the above example slide from ATI, we see a simple case in which dynamic flow control is used to draw a shadow on the ground.

The flow is simple: If the pixel is in shadow, fill it black. Keeping the thread size down to a small block of pixels makes dynamic flow control operations much more efficient, and ATI claims its thread size is the smallest in the business by a long shot.

The point of the new thread dispatch unit, separate texture units, fully associative caches, and improved compression, is efficiency. The primary differences are in the number of vertex and pixel shader units and the size of features like the dispatch unit and texture address unit.


The exact numbers are featured in the chart on back on page two. The above block diagram shows the basic setup of the vertex engine.

The X series cards have 8 vertex units, each with a bit vector ALU arithmetic logic unit and a bit scalar ALU, so each vertex shader unit can handle 2 shader instructions per clock cycle. This includes supporting dynamic flow control, longer shaders, and more temporary registers. AMD Radeon X1800 XT Graphics

Notice how the texture address units are separate: The maximum number of instructions that can be performed by a single pixel shader unit are listed on the diagram. Maybe break into 2 sentences?
