There are actually 3 versions of the 9800SE ? according to
ocfaq and more than that according to a little web searching?
The typical prices I?ve seen ?.
9800SE ? 380/340?. ? ? ? ? ? ?256bit bus? $220 (?) ? (= 9600pro?s performance)
9800SE ? ? 325/270 and 380/300 ? 128bit bus ? ~ $165 - 177 ? (much slower than 9600pro)
9800SE ? ? 325/250 ? ? ? ? ? ?128bit bus ? ~ $145 ? TSOP memory
PowerColor 9600pro ?400/300 ? ?? ? ? ? ? ?.$145
If you look at one of
digilifes latest articles they tested both a 256bit and a 128bit 9800SE. The 128bit 9800SE was clocked 325/270. That 128bit 9800SE was slower than a 5600 in almost all the benchmarks on that page. I would peg a 9600 faster than a 5600, so this would definitely put the 128bit model (325/270) slower than a 9600.
I would really avoid 9800SE?s unless you are thinking of softmoding.
