RV670 is the most controversial chip in ATI’s
history. ATI is trying to seduce its partners with some fake news, and legal or
not it confuses the market completely.
RV670 is suppose to be the R600 variation
with 256 bit memory interface done in 55 nanometre. It will feature 320 stream
processors and the PCB will less complex.
DAAMIT also hopes for 800+ MHz clocks and the new chip should have more ROPs
but we don’t know exactly how much more. Just to be on the safe side, ATI will
call this one a mainstream chip and two of them a high end at least for the
time being.

RV670 is more like R600 on 55nm
A lot of speculations
