The first 65nm processors from AMD are expected on the fifth of December, according to HKEPC:
Besides, the frequency multiplier for the upcoming 65nm products including AMD Athlon 64 FX, AMD Athlon X2 (Brisbane) and AMD Sempron (Sparta) have been changed to 0.5x. The integral multiplier limited a 200MHz (by Hyper-Transport Bus) separation between each existing model. The change of the multiplier could lower the separation to 100MHz, making the product line be more flexible.
Now, the new re-release models on 5 Dec include Athlon 64 X2 4000+, 4400+ and 4800+ and, are based on 65nm Brisbane with 512KB x2 L2 Cache. In addition, they are in 100MHz higher than the previous models. The new clock speeds are 2.1GHz, 2.3GHz and 2.5GHz respectively. All of them are in 65W TDP, no more 89W TDP version.
