"R600 is the 积电 80nm craft manufacture, the core area is 428mm2,
has 720 million transistors"
we already know R600 will have a 512-bit bus.
the top-end G80~GF 8800 has a 384-bit bus and 680~691M transistors
ATI's architectures have tended to out-perform Nvidia's given a level
playing field on shader-generation.
Nvidia was ahead for awhile with shader 3.0 GPUs while ATI only had
shader 2.0 GPUs
(GeForce 6 and 7 series vs ATI X800 and X850, a few years ago) but
once ATI caught up with shader generations with the X1800 and X1900,
ATI took back the performance crown. of course Nvidia is on top right
now because they've released the GeForce 8 series while ATI has yet to
release the next-gen Radeon, but when it does, looks like ATI (ahem
AMD) will be back on top.
yes, it is true that transistor count alone does not ensure top
performance. the 107M transistor ATI R300 trashed the 125M transistor
Nvidia NV30 in 2002-2003, but ATI has shown that it can beat Nvidia
with fewer transistors because their architectures are superior. now
with ATI likely to have more transistors, Nvidia could be in for an
even bigger thrashing. the 512-bit memory bus is actually the bigger
deal. however the MOST important thing is, the architecture of the
GPUs, the inner workings. Nvidia's 128 stream processors vs ATI's
64 (or more) unified shader ALUs.
will be interesting to watch.
