ATI Radeon R420 Roadmap

Zardon · Apr 13, 2004, 10:20 AM

First we have the names that will be attached to the VPUs that will scale across three levels of performance with the same VPU. The "X800XT" and the "X880XT" being the "same" card but with a different interface, with the latter being a PCI-Express X16 card. You will see that the PCI-Express core is labeled "R423" as it is in fact a native PCI-Express part and not the same CPU as the R420 with an adaptive bridge to allow the VPU to work on both interfaces. (It is yet to be seen if there is a performance impact from using a bridged VPU/GPU.) Notice as the clocks and memory speeds scale across the product line, so does the pixel pipelines that are turned on or off to further define performance levels.

They have to do something. They didn't want to use 5 digits or get rid of the radeon name. So they did x800. X stands for the 10. So you could also call it 10880XT
