AMD’s Athlon 64 FX lineup will get a few speed bumps within the next few months. The first speed bump will come next quarter in the form of the Athlon 64 FX-64. This part will be a Socket AM2 part and have a 125-watt TDP. It will presumably have a 3 GHz clock speed, as AMD likes to bump the clock speed of the Athlon 64 FX lineup in 200 MHz increments. The Athlon 64 FX-64 will be AMD’s desktop flagship processor until Q3’07 when the Athlon 64 FX-66 arrives. This part will have a 125-watt TDP as well and presumably be clocked at 3.2 GHz unless AMD has some other trick. It will be based on the 90nm Windsor core and not the upcoming 65nm Brisbane core.
According to the charts, we should be seeing some AMD 65nm action this quarter. Many of the ‘budget’ X2s with 2*1MB of Cache are replaced with 2*512Kb models. If you are looking to purchase a new AMD, it may be worth holding out for some of the 65nm models though.
