Exclusive precise die sizes of RV610 and RV630
http://www.beyond3d.com/content/news/129 - RV610 is 7.7x10.7mm, or ~82mm² on 65nm.
http://www.beyond3d.com/content/news/130 - RV630 is 13.3x11.5mm, or ~153mm² on 65nm. And Rys also measured G86 and MCP73 previously, also at CeBit: http://www.beyond3d.com/content/news/123 - G86 is 11.5x10mm, or ~115mm² on 80nm. http://www.beyond3d.com/content/news/111 - MCP73 is ~135mm² on 80nm(?). All of these measurements have an error margin of, most likely, less than 5%. No promise on whether we'll get a G84 measurement, but it's still on Rys' list of things to try doing. Anyway, enjoy, and you may now speculate to your heart's desire with a bit more concrete info!

Cool, looks like ATi has a pretty hefty die size advantage in the meaty part of the market this time around. Can't wait to see the 65nm vs 80nm face-off.

Didn't ATI have a pretty hefty die size advantage with X1800 vs NV 7900 as well (meaning, larger die size for X1800)? Just goes to show that it's not all about how big it is, but how you use it.
Edit: It actually does appear that NV has a somewhat larger die size for G84/G86 vs RV610/630. I suppose that is due in part to 80nm process vs 65nm process. I can't say for sure what cost would be like, since we are comparing 80nm vs 65nm. Last edited by jimmyjames123; 16-Mar-2007 at 15:26. |

By "advantage" I mean size and cost
 IIRC X1800 was not smaller than G71, quite the opposite actually.

Yeah, I remembered that after I typed my comment. Good thing that they didn't name these midrange parts G90 or R700 to make things more confusing

G90 is a dual core G80, and R700 is.. er, probably an octo core RV610!
