According to this article on the Chinese website, ATI's next generation card, the one with 512MB memory that should be released at a Texan Gaming party, the R520, will probably be called the X950XT.
In performance terms, it will be at least four times quicker than a X800Pro which was itself four times faster than a 9800se.
Moreover, it seems that the memory and core speeds will be 900MHz and 750MHz respectively; the latter figure being actually quite high. As for the vendor ID, 0x1046 corresponds to IPC Corporation LTD. That's all folks. µ
