TDP of up to 136 Watts
Ad
The email mentioned above goes on to state that the new Core 2 Extreme QX9770 will have a specified TDP of 136 Watts. From this we can deduce that no current Intel chipset – be it the X38 or the P35 – will support the new CPU, since they are only specified for a maximum TDP of 130 Watts. This high thermal design power given by Intel raises a few questions in our minds. In our measurements with the current QX9650, which runs at 3.00 GHz at stock speeds, we only recorded a power consumption of less than 73 Watts. So how does Intel arrive at a TDP of 136 Watts?

Update: We measured the power consumption of the new CPU and compared it to the QX9650. Running both CPUs at an identical frequency of 3.00 GHz on a 333 MHz FSB (1333QDR) with stock core voltage, we measured a difference of roughly 26 Watts. On our Gigabyte GA-X38-DQ6 motherboard, the QX9770 running at 3.20 GHz drew 103.5 Watts. Its predecessor, the QX9650, was more frugal, undercutting its younger sibling by 30.6 Watts. |

Update: The new model also operated stably at 4.00 GHz once we increased the core voltage to 1.40 Volts. Here we are seeing the benefits if the K-Gate technology of the 45 nm process. |

Update: Intel has meanwhile confirmed that the QX9770 is rated at a TDP of 136 Watts, meaning that the maximum thermal dissipation was raised by 6 Watts compared to the QX9650. Intel’s comment: “The TDP is a specification that is primarily of interest to system builders (OEMs). It allows the OEM to design as system that can handle the heat generated by the processor based on this value. The unchanged TDP rating simplifies the process of designing and building new systems. To the end user, the value that is more interesting is power consumption on a system level, i.e. how much power the entire PC, server or laptop consumes.“ |

Apart from neding a new chipset, what's the deal with a mere 5% performance increase for an additional 40% more power consumption.
Given the impressive energy efficiency of the QX9650, I don't understand how so much extra power is drawn for the tiny boost in performance - what's going on?
