Last weekend AMD hosted a large demonstration of their upcoming new processors in Japan. Namely, they showcased their new Athlon 64 6400+ and Phenom FX processors. This event has become the second place where a working engineering sample of AMD Phenom FX processor was revealed. Just like last time, the long-awaited quad-core desktop processor on K10 micro-architecture worked at 3.0GHz in a single-socket platform.

According to AKIBA PC Hotline, AMD again refrained from demonstrating any performance results, unfortunately. The audience could only make sure that the Phenom FX system was operational in popular applications in a 32-bit Windows Vista OS. The only value that could give an idea about the platform performance was the Windows Experience Rating that equaled the maximum possible value of 5.9.

Besides Phenom FX processors working at 3.0GHz, this system also included an RD790 based mainboard, two Radeon HD 2900 XT graphics cards in Crossfire configuration and 4GB of RAM. AMD representative talking about the performance of this platform claimed that it is much faster than a Quad FX system with two dual-core 3GHz processors from the previous-generation. They also pointed out that the demonstrated CPU was a new Phenom FX, and not the one that they had previously showcased in the US. So, AMD gave everyone to understand that they have more than one working engineering sample of a new 3.0GHz processor on K10 micro-architecture, although the first Barcelona processors that are scheduled to come out in September will not get beyond 2GHz frequency limit.

Together with the Phenom FX systems, AMD representatives officially confirmed that AMD Athlon 64 X2 6400+ was also expected to be released very soon. This dual-core processor on K8 micro-architecture will be designed to work at 3.2GHz and will be based on Windsor core manufactured with pretty mature 90nm technology. So, AMD Athlon 64 X2 6400+ will have the total of 2MB L2 cache and 125W TDP. It will be priced at around $240.

AMD Athlon 64 X2 6400+ will ship in an original black box called Black Edition. AMD Athlon 64 X2 6400+ Black Edition may come out on August 20, as reported.
