Posted by unknown_lamer [send private reply] at November 29, 2002, 09:07:27 PM No, the R300 is already out. You can purchase a Radeon 9xxx right now. And it owns everything that nVidia has down the pipeline.
Posted by CodeRed [send private reply] at November 30, 2002, 01:00:38 AM No it doesn't man, don't just say stuff without knowing what you are talking about, lets compare
Pixels per clock:
r300 - 8
nv30 - 16
Textures per rendering pass:
r300 - 16
nv30 - 32 (twice the number of texture pipes)
Texture address operations per pass:
r300 - 32
nv30 - 1024
Color instructions per pass:
r300 - 64
nv30 - 1024
Pixel shader precision:
r300 - 96bit floating point
nv30 - 128bit floating point
Integer color modes:
r300 - 16, 32, 64
nv30 - 16, 32, 64, 128
Transistors on die:
r300 - 110mil
nv30 - 125mil
r300 - 4x
nv30 - 8x
Adaptive texture filtering:
r300 - no
nv30 - yes
4:1 loss-less color compression:
r300 - no
nv30 - yes
Fabrication process (smaller is better):
r300 - .15 micron
nv30 - .13 micron
r300 - 300mhz
nv30 - 500mhz
r300 - DDR
nv30 - DDR2
I could go on if I wanted to keep searching google but it is 2am and I am tired. The point is what you said "it [the r300] owns everything that nVidia has down the pipeline" is simply wrong.
Posted by unknown_lamer [send private reply] at November 30, 2002, 02:53:47 PM NO. The R300 /is/ faster. Processor speed isn't everything; the R300 has twice as much memory bandwidth...and it doesn't really matter because the FX hasn't been released yet, and by that time the R400...
And from your chart, you left out the memory bandwith part:
FX - 16 GB/s
R300 - 19.8 GB/s
But still, the FX isn't going to be released any time soon. You can always use a DDR2 memory controller and increase the clockspeed of the R300 to make it compete better (eep, you can run a R300 with only passive cooling).
Posted by CodeRed [send private reply] at November 30, 2002, 08:50:00 PM "Processor speed isn't everything" That is why I listed all the other stuff like pixels per clock, textures per pass, etc. Memory bandwidth isn't everything
Posted by unknown_lamer [send private reply] at November 30, 2002, 09:11:00 PM If you read the article you are taking the chart from, toms essentially says that the R300 clocked a little bit faster would own the FX (by a little I mean about 20Mhz or so).
Posted by CodeRed [send private reply] at November 30, 2002, 09:28:16 PM Yes, but I can overclock my Geforce 4 by 100mhz core, 150mhz mem, I would expect the same from the geforcefx
Posted by CViper [send private reply] at December 01, 2002, 05:10:07 AM overclocked or not, you can't just increase precision, instructions per pass (pixel shader/vertex programs) and that kind of stuff. And IMHO that's the stuff coming more in the future.

CViper, the nv30 is better at those things, I am arguing for the nv30, check my first post in this thread
Posted by buzgub [send private reply] at December 01, 2002, 09:26:11 PM This argument is futile. Even if the nv30 is the best when it's released, ATI will top it in a few months. A few months after that, nvidia release a new card that tops ATI's effort. Rinse and repeat.
This is what happens with computer hardware, folks. Arguing about what's best is useless - just buy the best thing within your budget that serves your needs, and be done with it.
Posted by CViper [send private reply] at December 02, 2002, 08:36:07 AM CodeRed: yes, the reply was ment to "support" you :P
buzgub: agreed. I didn't start the first thread to start an argument; rather by a mistake/brain already at sleep (1ghz turned somehow 1gb in my mind...).

Oh.... sorry ;)
