Vertex Shaders

R300:
Max Instructions: Up to 1024 instructions with flow control.
Max Constants: 256
CineFX:
Max Instructions: Up to 65536 instructions with flow control.
Max Constants: 256

Pixel Shaders
R300: Up to 160 instructions with 128-bit F.P. precision.

Looks good. *drool*. Of course games using these specs wont be out for a while.

Forget the games...... what monitors are gonna be able to show you all those vertex pixel 128bit color thingies :eek: (at a reasonable price :eek: )

Shouldn't all modern CRT and LCD screens be able to show anything produced by the graphics card, as it is given pixel by pixel.

Stop comparing next gen cards, with cards that are comming out even later, theres no point. Thats like comparing a GF2, to a GF4. Also, ATi are releasing a updated version of the r300 when the NV30 comes out :)that will be on 0.13 micron process "vpu", and DDR-II.

Grrr!!

I agree with Volodkovich, but this stuff does have a certain drool factor :D.

The 128-bit Floating Point precision is only used internally. The DAC's on these cards ( R300 being 128bit internal as well ) will down-sample to 32-bit colour before output. The purpose of the 128-bit internal precision is purely the elimination of rounding errors.

I R so smart :p
