Here



RADEON 9800
8 rendering pipelines
256-bit memory bus
128MB of DDR SDRAM,
$299
325MHz for core
580MHz for memory.


RADEON 9800 SE.
Two versions of the RADEON 9800 SE:

One with 128-bit memory
speeds comparable to that of the RADEON 9600-series,

Second more powerful using 256-bit memory bus,
modified R350 core
4 rendering pipelines.
325/600MHz for graphics processor/DDR SDRAM
price will be about $200 - $249


There ya go.

One question: why?

 

[Lonyo]

The one with 4 pipelines makes sense as a card, because any failed R350 cores that have errors in som epipelines can be used rather than binned.

The simplified card with 128-bit memory bus may also make sense, if there are cores that cannot hit the speeds required for the non-pro card.

If you have 4 chips produced, and one can hit 350MHz (or whatever pro speed is) it can be kept and used.
One hits 325, non-pro material.
One hits 275 or something, perfect SE 128-bit mem bus material (made up MHz number)
One has only 6 pipelines that are OK, perfect SE 256-bit material.

All for produced cores can be used, no waste. Excellent production therefore.

Thats the idea I had on why they might do it.

i agree..thnks for that explanation, it's the most logical i've seen
