This kind of filtering enhances the quality for images that are not on the conventional plan. ATI has been working for years on a high-performance shader compiler in their driver for their older hardware, so staying with a similar basic design that is compatible offered obvious cost and time savings. In games where we tested both with and without antialiasing, we will also show a graph of how performance drops due to AA scales with resolution. The X cards have 3 pixel shaders on each pipeline instead of 1, giving a total of 48 pixel shader units. Log in Don’t have an account? This modular design allows ATI to build a “top to bottom” line-up using identical technology, saving research and development time and money. Since we’ve only had a week and a half with the cards, we had to leave out the Radeon X Pro.

The chip also ups the vertex shader number from 6 on X to 8. The Radeon X XT. The X Pro is the first ATI card that supports native Crossfire implementation by a pair of internal Crossfire connectors, which eliminates the need for the unwieldy external dongle found in older Crossfire systems.

You may be wondering when these products will actually be available for purchase. Radeon X for the entry-level market, Radeon X seriea the mid-range market and Radeon X for the high-end market.

Archived from the original on May 7, Along these ring buses are 4 “stop” points where data exits the ring and going into or out of the memory chips. About us Privacy policy Mailing list Mobile. ATI has taken this step with the expectation that future 3D software will be more pixel shader intensive.


With chips such as RV and R, where the number of shader units per pipeline triples, the x1000 of pixel shading drops off slightly because these shaders still have the same level of threading resources as the less endowed RV and R Anisotropic filtering is used to get a sharper image and to not become fuzzy like in this example.

The chips have 4 texture units4 ROPs4 pixel shadersand 2 vertex shaderssimilar to the older X – X cards.

ATI’s X Series: Extended Performance Testing

For example, the X sries 4 “quads”. Three of the cards, including the X XL, should be available todayif all goes according to plan.

Most of ATI’s current Radeon lineup should go the way of the dodo once these cards filter out into the market in sufficient volume. The red team’s track record on product availability has been rocky in the past year or so, but perhaps this round will be different. When one of the shader quads becomes idle, due to a completion of a task or waiting for other data, the dispatch engine will assign the quad with another task to do in the meantime, with the overall result being a greater utilization of the shader units, theoretically.

For those who worry about the expected power consumption of such a powerful card, ATI has implemented dynamic x000 control to throttle power and hence, heat output when necessary. No Interruptions Day Shortbread.

Ruby’s latest nemesis, Cyn, was composed ofpolygons. Current technologies and software.


ATI’s Radeon X series GPUs – The Tech Report – Page 4

ATI’s Next Chapter Early this month, the long wait and intense speculations were finally put to rest. ATI Technologies products Video cards.

ATI will document its architecture, i. The next major change to the core is with its memory atii.

Our test suite for the other cards wouldn’t be appropriate xti the X Pro or its competitors. Not only are they fully Shader Model 3 capable, but ATI introduced some innovative advancements in shader threading that can greatly improve the efficiency of the shader units.

However, these are the models that we had access today and should represent the more popular ones that ATI is focusing.

Views Read Edit View history. CrossFire support for all models. Neutronbeam Zak, you know you can’t validate any of the above details without first throwing HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup. Radeon X series uses a bit floating point register for HDR, using bit for each video component.

This new series has basically three families, each one for a distinct market segment: This means that RV has the same texturing ability as the X at the same clock speed, but with its 12 pixel shaders it encroaches on X’s territory in shader computational performance.
