Core 2 Extreme QX6800 review benchmark and overclock



When everyone wait for the next upgraded processors Core 2 Duo with FSB1333 in the current summer, and for the future processors 45nm Intel planned in the end of year, Intel introduced Core 2 Extreme QX6800.

New High-end-range processor come to supplement, the current Core 2 Extreme QX6700. Intel proposes to us the QX6800, processor quad core work at 2,93 GHZ, the same as Core 2 X6800 released in July 2006, but this last has only two core.

Intel Core 2 Extreme QX6800: An already known architecture

Without much surprise, Core 2 Extreme QX6800 which Intel proposes to us today is made on Kentsfield core, already used in Core 2 Extreme QX6700 and Core 2 Q6600 . Let us recall that the following example was made with Pentium D, Intel joins together on the same physical chip two cores Core 2 Duo.

Intel Core 2 Four-core

With the absence of the most effective architectural level, the technique adopted by Intel ensure a good release rate in the production of its processors quad-core. It is easier to produce dies with small size rather than only one enormous die joining four core.

Intel Core 2 Extreme QX6800: review

Core 2 Extreme QX6800 has the Socket LGA-775 and preserves the heat-spreader appeared with the first Pentium 4. Its thermal envelope is fixed at 130 Watts, witch is largely higher than Core 2 Duo E6700. The QX6800 is not an economic processor in energy terms. In full load, its temperature rise easily to 48° C, against a maximum of 40° C generally observed in Core 2 X6800 Extreme which operates at the same frequency 2,93 GHZ.
