ATI's R600 driver indicates four flavours ahead

THE DRIVER FOR the R600 appears to indicate there will bet at least four different versions of the card.

"R600" = ati2mtag_R600, PCIVEN_1002&DEV_9402
"R600 " = ati2mtag_R600, PCIVEN_1002&DEV_9403
"R600 " = ati2mtag_R600, PCIVEN_1002&DEV_9400
"R600 " = ati2mtag_R600, PCIVEN_1002&DEV_9401

DAAMIT is still uncomfortable using any names due the leaking problems and each of these cards has its driver, for secondary display. We don't know the difference between the cards, uet.

One industry source implied a possible XTX, XT, PRO and GT branding, but we cannot confirm this. This bit puzzles us.

[ati2mtag_R600.GeneralConfigData]
MaximumDeviceMemoryConfiguration=512
MaximumNumberOfDevices=4

There are two possibilities. The first is that each card supports 512MB of memory only and that you can Crossfire up to four cards. The second is that the card has four different memory devices and can address up to 2GB of memory. We still don't know the answer but will tell you when we do.

"R600 Secondary" = ati2mtag_R600, PCIVEN_1002&DEV_9421
"R600 Secondary " = ati2mtag_R600, PCIVEN_1002&DEV_9422
"R600 Secondary " = ati2mtag_R600, PCIVEN_1002&DEV_9423
"R600 Secondary " = ati2mtag_R600, PCIVEN_9420

The cards are about a month away from a public announcement. µ
