Rv770 is core name for HD4800 series,
RV770PRO is codename/core name for HD4850,
RV770XT is codename/core name for HD4870,

R700 is codename(not sure about core name) for HD4870x2

Very nice, I like how clean it is.(the structure)

R700 use 6pin+8pin connector, just like 3870x2 does biggrin.gif

PLX chip seems smaller than 3870x2 PLX chip (die shrunk? or just middle man for communication between GDDR5 and Rv770 core? who knows..)

R700 Black Edition anyone? laugh.gif

AMD will be in a position to supply samples for internal testing and quality evaluation by 15th of July and July 24th is slated for completion of testing following which, the product could start shipping. Partners will receive chip samples for non-reference designs. Volume shipments of the chips could commence sometime in August.

This is Spartaaaaaaaaaaaaaa anyone?


R700 Spartan has 2GB of memory : http://www.fudzilla.com/index.php?option=c...=8279&Itemid=34
QUOTE
Comes in late August

We just got a final confirmation that R700 uses two RV770XT GPUs and that it supports massive 2GB of GDDR5 memory.

ATI used the codename Spartan for R700, as someone got hot for the movie.

R700 avg 50%, up to 80 % Faster than GeForce GTX 280 : http://www.techpowerup.com/65382/R700_up_t...ce_GTX_280.html
QUOTE
Pre-release performance evaluations suggest that the Radeon HD 4870 X2 2GB GDDR5 model will on an average be 50% faster than the GeForce GTX 280 and in some tests 80% faster. A second model, the HD 4850 X2 (2GB GDDR3 memory, 2x RV770Pro) will also convincingly outperform the GeForce GTX 280. The R700 series will be brought into the market late-July thru August.

might be rumor tho
