Pentium 4 with 2.4 GHz in the test: The new front runner

Pentium 4 with 2.4 GHz in the test: The new front runner

Power consumption

Before we chase our test candidates through the benchmark course, we let them compete against each other in terms of consumption. It should be clear from the outset that the new Northwood should have an advantage here thanks to its smaller manufacturing technology and lower core tension. But with every increase in the processor speed, the power consumption of the processor increases noticeably. Especially with a jump of 200 MHz, as Intel did with the Pentium 4 with 2.4 GHz, clear differences should become apparent.

Processor core voltage Maximum core voltage Consumption Athlon XP 2000+ (1.66 GHz) 1.75 volts 2.1 volts 62.5 watts Athlon XP 1900+ (1.60 GHz) 1.75 volts 2.1 volts 60.7 watts Athlon XP 1800+ (1.53 GHz) 1.75 Volt 2.1 Volt 59.2 Watt Athlon XP 1700+ (1.46 GHz) 1.75 Volt 2.1 Volt 57.4 Watt Pentium 4 2.4 GHz (Northwood) 1.5 Volt 1.75 Volt 57.8 Watt Pentium 4 2.2 GHz (Northwood) 1.5 Volt 1.75 Volt 55 Watt Pentium 4 2.0A (Nothwood) 1.5 Volt 1.75 Volt 52 Watt Pentium 4 2.0 (Willamette) 1.75 Volt 2.1 Volt 75 Watt

The table clearly shows that the consumption of the Pentium 4 with Northwood -Core is well below that of an athlete. You can also see the savings in consumption by switching to 0.13 µm production technology. At the same speed, the Pentium 4 with 2 GHz and Northwood core needs a whole 23 watts less than its predecessor with a Willamette core and 0.18 µm technology. The clock increase by 200 MHz only takes a good 3 watts. Nevertheless, at a clock rate of 2.4 GHz it only devours as much as an Athlon XP 1700+ at a clock rate of 1.46 GHz, which is of course quite impressive.

Pentium4 2.4


As usual with us, this time we will briefly go over the requirements for the new Pentium 4 a. In general, everything that has already been extensively explained in the processor comparison applies. Whether a Pentium 4 2.0A or a Pentium 4 with 2.4 GHz is used shouldn't matter to the power supply. If an old Willamette model was used before, the consumption is even lower with the new Pentium 4. With a 300 watt power supply you are definitely on the safe side and even 250 watts shouldn't cause any problems.

With current mainboards, usually no BIOS update is necessary to support the new model, although it would of course not hurt. The processor definitely works. So if you call a Socket 478 motherboard your own, you are well equipped for the 2.4 GHz Pentium 4.
