Specification Overview
The heat spreader is an essential element of Intel's processors that both ensures heat dissipation and die protection.
The new top model will be the Pentium 4 Processor 560, which runs at 3.6 GHz. Four other versions, with model names 550 to 520, run at 3.4, 3.2, 3.0 and 2.8 GHz. While the TDP was 103 °C for the socket 478 Pentium 4 Prescott at 3.4 GHz, the maximum power output now will be 115 W. As a result, there's not much overclocking margin with the top models. More than ever, you should keep a close eye on the thermal parameters if you plan to go for a LGA 775 machine.
| Processor | Frequency | Thermal Design Power (TDP) | Tcase | VID |
|---|---|---|---|---|
| Pentium 4 520 | 2.8 GHz | 84 W | 5 - 67.7 °C | 1.25 - 1.40 V |
| Pentium 4 530 | 3.0 GHz | 84 W | 5 - 67.7 °C | 1.25 - 1.40 V |
| Pentium 4 540 | 3.2 GHz | 84 W | 5 - 67.7 °C | 1.25 - 1.40 V |
| Pentium 4 550 | 3.4 GHz | 115 W | 5 - 72.8 °C | 1.25 - 1.40 V |
| Pentium 4 560 | 3.6 GHz | 115 W | 5 - 72.8 °C | 1.25 - 1.40 V |
Intel recently inaugurated their Fab 24 in Leixlip, Ireland, which is the fourth facility to produce chips on 300 mm wafers. However, the majority of processors shipped these days is still based on the 130 nm Northwood core.
