The 9500/9700/9800 has 1:2 Shaders to Pipelines. Meaning, in the case of the 9500 Pro, 9700 series, and 9800 series excluding SE, there are four shaders.
The 9600 series is 1:1 on shaders to pipelines. Combine that with the higher clock rate of the core and you have the ability to do many more shaders on a given frame without bogging down.
In layman's terms, you'll have the ability to cram more special effects into a given frame although you may not have as many frames.
Someone should write a benchmark that runs better on the 9600, just to show it can be done.
Erm, no?
All the 9500P+ cards have one pixel shader per pipeline, just like all of nV's cards. (I believe the
pixel shader has to be integrated into the
pixel pipeline by definition, though I may be wrong--if not WRT current cards, then possibly WRT future cards that support DX Next's unified shader models.) The 9500P (a R3xx series chip) has two more vertex shaders and also some HyperZ features that the 9600 (a R
V3xx series chip) lacks, so it may be a
tad faster clock for clock in certain games.
So the 9500P, 9700, and 9800 all have eight pipelines with a pixel shader per pipe, as well as four vertex shader engines. The 9600+ has four pipes with a PS per pipe, as well as two VS engines. I believe the VS was tweaked in the 9600 and possibly 9800 series, so their VS engines may be faster clock for clock than the 9500's.
I appreciate how Rollo overlooked the fact that the 9500P was a temporary card, a wolf in sheep's clothing--really, a gift to mainstream consumers. The 9600XT competes with the 5700U, not the 9500P. (Check some of
Digit-Life's ethically-questionable benches of the HL2 leak--the 5700U gets stomped, even with the coveted all-improving "Unified Compiler Tech" Det 52's.). He also overlooked the fact that the 9600XT outpaced the 9500P in a few later games. I was surprised that the 9600XT was slower than the 9500P in the DX9 games, but the XT is still 50MHz shy of theoretical shader parity with the 9500P, and it's also missing some HyperZ elements which should help a lot in memory-intensive shaders.
Rollo, no need to get troll-y with your threads, buddy. We all know the mainstream cards pale to the high end WRT to full effects. Why give the more excitable folks here an excuse? Do you miss DefRef's posts that much?

bunnyfubbles was right. Take a #3, and post in the morning.
