The Inquirer found out a bit more about ATI's RV570. They report it's an advanced version of the Radeon X1600 with the bridge chip inside and a 256 bit memory interface.
RV570 should be just as fast and the production cost will be much lower. Secret of the RV570 is that the chip is built on 80 nanometres and it looks like ATI might move to 80 nanometres faster than we all expected.
We've heard about the RV560 before and we also heard that it is a 256 bit chip that should inherit the RV530 mantle. We should be talking about the same twelve pixel pipelines but that's not clear at this point. This chip is architecturally the same as RV570 and the only difference is that it will be produced at UMC.
