Intel Core 2 Extreme QX9770 & Q9450 in the test: The Ferrari among CPUs

Temperature

For the temperature measurement, the closed system was heated up for one hour in the 3DMark06 loop and the temperature values ​​then with the combination of Prime95 and 3DMark06 determined. The room temperature wasat around 21 degrees, the temperature read from the mainboard at full load at a maximum of 46 degrees.

The new four-core processor from Intel impresses with temperatures that are similar to those of a Core 2 Quad Q6600. With its 3.2 GHz, the QX9770 is still a lot easier to cool than the most powerful quad-core CPUs of the previous generation. The QX6850 with 3.0 GHz is a whopping 20 degrees Celsius above the new model, which was to be expected given the high power consumption. Again, it should be noted that the results for the new Core 2 Quad Q9450 are of a preliminary nature, as the final voltage with which the processor will be delivered has not yet been determined. Placement below the Core 2 Extreme QX9650, as determined in our test procedure, should appear more than logical.
