The new 3500+, 3200+, and 3000+ perform from 1% to 7% faster than comparable 130nm parts.

AMD claims that their 90nm process generates less heat than the 130nm process and requires lower wattages. Of course, the heat that is generated is concentrated in a much smaller area than the larger 130nm die. We will not likely know the true impact of the 90nm shrink on heat dissipation until AMD produces their fastest CPUs in 90nm, so we decided not to run comprehensive heat tests until the faster processors were available in 90nm.
....
As you can see, the 3500+ and the 3000+ both topped out at about 2.6GHz... This means that the new 90nm 3000+ overclocked an outstanding 45% with modest increases in CPU voltage.
...
They will love the new 90nm chips because they can buy a 3000+ running at 1.8GHz for less than $200 and still have a good chance of reaching 2.6GHz with very little effort with the same chip. 2.6GHz is faster than any current Athlon 64, and it is, in fact, the speed that we expect from the upcoming FX55 - the new Athlon 64 top-of-the-line. It's been a while since we've seen this kind of headroom on an AMD chip, and those who were waiting for 90nm to get a magic overclocker will get in line to buy the new 90nm 3000+.
