Well unless you've been living under a rock since Monday,
you've probably noticed we
have access to a few R600 cards.
One thing that concerns me is that many of our readers may think the 750 MHz core
clock on the Radeon HD 2900 XTX, if it even comes to market, will be the final
clock. I can almost guarantee you that if anyone decides to bring this to
channel, the core clock will get a bump. Keep in mind that Sven managed
to overclock the core to 845 MHz on the XT card.
In addition, I was quite pleased with the HD 2900 XT tests. I do believe
when overclocked -- and this card seems to have a bit of headroom -- the card
does well against the 8800 GTS and starts to encroach on the 8800 GTX
territory. In our testing, it doesn't beat a GTX, but then again it won't
be a $500 graphics card either. That task was reserved for the XTX and I
think it’s quite obvious that increasing the memory size and frequencies on the
R600 GPU won't usurp the 8800 GTX.
I won't pretend that the tests we did were exhaustive. Since DailyTech
does not sign embargos, we sort of get what we can take when it comes to
publishing early tests. Scott Wasson, Ryszard Sommefeldt and Anand Shimpi
are true experts when it comes to GPU performance, and if you have any
reservations about our preliminary examinations, certainly wait for their
In conclusion, what did the HD 2900 XTX benchmarks really show? I think
the most obvious answer is that the difference between 1GB GDDR4 and 512MB
GDDR3 is certainly not going to be a viable option for R600. Like
we had mentioned before, this card is at least partially scrapped at this
point, save a few OEMs who will be putting it into workstations.
