AMD cancels Dual Core and FX Phenoms on K10 base
Although they were announced with the introduction of the new K10 micro architecture, not even a single sample of the Phenom FX series was released until today.
And as the Chinese website hkepc.com reports, this will not happen, any time soon. According to sources in Taiwanese motherboard industry, realizing a higher clock speed is giving AMD that much trouble that the company decided to put the Phenom FX CPUs on hold. Since the already announced Phenom X4 9950 has a TDP of 140 watt, there is no point aiming for higher clock speeds with the 65 nanometers architecture. But AMD wants to keep an eye on the high-end market and scheduled for 2009 to change to 45 nanometers structure.
Furthermore it seems like AMD has also cancelled models with two cores, codename Kuma, which were scheduled for July 2008. The reason for this decision is said to be the fact, that the Tri Core Phenoms with their low prices would not allow for Dual Core CPUs based on the K10 architecture. The Athlon X2 6050B, which was listed on older roadmaps, is said to be replaced by the Athlon X2 5600B with a Brisbane core.
