The recently announced and tested Athlon X2 6400+ Black Edition has now finally been added to AMD's offer and is already on its way to stores.  At 3.2GHz, the 6400+ runs 200MHz faster than the X2 6000+ and contains 1MB of L2 cache per core. Also like the 6000+ the chip is built on AMD's 90-nm process with a max thermal power of 125W. As its Black Edition branding denotes, the Athlon 64 X2 6400+ Black Edition will be sold exclusively in a black box and without a heatsink/fan unit. The CPU is priced at $239 in quantities of 1,000 and will be sold to channel partners only, system vendors will not be offering a 6400+ SKU.

AMD is also offering an Athlon 64 X2 for notebooks. With the model number TK-53, the 1.7GHz chip has 512KB of L2 and a 1600MHz HyperTransport bus. That's the same frequency as the member of AMD's current Turion 64 X2 dual-core mobile processor line-up, all but one of which contain 1MB of L2 and clocked from 1.6GHz to 2.3GHz. The cheapest Turion costs $154 in batches of 1000 CPUs, while the TK-53 costs $144 in the same quantities.
