At this time AMD doesn't have the technological possibility to announce a quad-core processor. But the company doesn't give in and bravely responds to Intel's Kentsfield with a dual-socket platform for dual-core processors. But how good is this alternative? The first reviews can be found on AMDZone, HardOCP, HotHardware, PC Perspective, and X-bit labs.

First of all, the performance of a dual-processor platform built with two dual-core Athlon FX processors turned out lower than that of the competitor's solutions built on quad-core Kentsfield CPUs. We have seen this in all test applications throughout the entire session. Secondly, Quad FX platform is often slower than the regular Socket AM2 system with a single CPU because of the higher memory subsystem latency. NUMA technology that proved highly efficient in servers turned out to do more harm than good in the desktop space. Thirdly, from the performance-per-watt prospective Quad FX platform loses not only to Intel Kentsfield based solutions but to all other platforms as well. The sky-high heat-dissipation and power consumption of this platform also set specific requirements to power supply units, system cases and system cooling.

In other words, AMD Quad FX will most likely appeal only to the most dedicated AMD fans. For everyone else this platform will most likely be none other but a unique desktop system prototype showing the possibility (or maybe even uselessness) of introducing AMD's server technologies into the desktop sector. Although we cannot deny that the upcoming AMD processors based on promising K8L micro-architecture will give new meaning to the exciting Quad FX concept.
