No, the R300 is already out. You can purchase a Radeon 9xxx right now. And it owns everything that nVidia has down the pipeline.

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 Antialiasing precision: 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 Core Speed: r300 - 300mhz nv30 - 500mhz Memory type: 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.

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).

"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

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).

Yes, but I can overclock my Geforce 4 by 100mhz core, 150mhz mem, I would expect the same from the geforcefx

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.

"you can't just increase precision, instructions per pass (pixel shader/vertex programs and that kind of stuff"
CViper, the nv30 is better at those things, I am arguing for the nv30, check my first post in this thread

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.

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 ;)
