We previously discussed ATI's RV515 in some detail and mentioned that it would be a follow-up product to RV370 and carry 256MB memory with a core running at roughly 550MHz.
However, we just received information from sources close to ATI, that the X1300 series will pack more bang for the buck with BBA (built by ATI) and AIB designs moving forward. ATI will be producing its RV515 Pro SKU's at 600MHz clock speeds and be configured with either 512MB DDR2 or 256MB GDDR3 memory clocked at 400MHz.
RV515 LE, or simply Radeon X1300, will also come with 512MB of memory and in PCIe and AGP flavors. Other board manufacturers however, are free to produce cards based on other memory configurations.
Lastly, for those who are interested in Crossfire configurations, ATI recently indicated that Crossfire configurations for Radeon X1300 and X1600 will no longer require a master card. This means you may purchase any two different brands and be certain that Crossfire will be supported.
