Intel Pentium 4 3066 MHz in the test: HyperThreading for the desktop

Processors at a glance

For all friends of the no-frills theory, before we get down to the nitty-gritty, we want to take another look at the key data of the opponents.

Processor details of the 3.06 GHz P4

Except for the fact that Hyper-Threading on the new Pentium 4 has been activated, there are no changes. Even the processor core is absolutely identical. This confirms once again that, as already mentioned in our Hyper-Threading Basics , every Pentium 4 has the basic structures for Hyper-Threading.

The fact that our test model comes with a Vcore of 1.550 volts should not worry anyone, since Intel has recently started offering every Pentium 4 processor with four different voltages. So it may well be that a 3.06 GHz Pentium 4 with a core voltage of 1.475 volts will also appear on the market.

Thus, the new Pentium 4 is also based on the proven Netburst architecture that comes with following basic elements.

Since all of these We do not want to go into any more detail here.

New overclocking opportunities

Even though Intel is now the 3rd generation with the new Pentium 4 GHz, the processor still seems to have potential for higher clock speeds. With regular air cooling and an operating voltage increased to 1.65 volts, 3633 MHz were possible on our test mainboard in active Hyper-Threading mode.

The sense of overclocking can be questioned, because needs even more power definitely not a desktop system at the moment.
