Is ATI's 80nm schedule on track?
According to industry sources quoted by
DigiTimes, ATI has decided not to introduce any parts based on 80nm
process technology this year. The move, they claim, is due to Taiwan
Semiconductor Manufacturing Company (TSMC)'s inability to improve yields
for its 80nm process. ATI denied the allegations when asked by DigiTimes
directly, however, saying "its migration schedule to 80nm for 2006 has
not changed," and that a move to 65nm is still on track for next year.
Earlier rumors that ATI's GDDR4-based R580+ would be 80nm-based have
been proven false, but the company is still
expected to introduce RV560 and RV535 GPUs based on TSMC's 80nm
process this year. The RV560 will reportedly be used in a Radeon X1700
graphics card due out in the "back-to-school season," while the RV535
will appear as early as the summer in updated X1600 cards.
Despite these reports, DigiTimes' sources say the 80nm delays will
result in the RV560 being fabbed on a 90nm process. They didn't mention
which process technology the RV535 or a so-called RV505 would end up
using, though, so those parts could still be candidates for early 80nm
adoption. The RV505 was reported by Chinese site PConline last year as a
future 80nm GPU designed for a low-end Radeon X1300 CE graphics card (translate here).
