Under UnrealTournament, the Duron 700 lies between an Athlon 600 and an Athlon 700 in terms of performance, although it is closer to the former.
In comparison to a Celeron, it is definitely faster than the retail 66MHz FSB parts, and it comes out just slightly slower than an overclocked 850/100MHz part.
Memory bandwidth limitations begin to kick in and help to limit the GeForce 2 GTS' potential which lowers scores a bit, but the standings are still fairly similar. The Duron 700 comes out as being just as fast as an overclocked Celeron 850, faster than an Athlon 600 and definitely faster than a 66MHz FSB Celeron. Even the upcoming 700MHz Celeron won't be able to touch the Duron 700, the 600MHz Duron may be cutting it close however.
