CeBIT: Air-cooled and stable at 2 GHz
Intel presented a Pentium 4 behind closed doors at CeBIT 2001 in Hanover, which is operated at 2 GHz. Well, nothing special one might think. But: The Pentium 4 is air-cooled.
The system shown consisted of a board with an Intel 850 chipset and 256 MByte RAM bus memory. During the boot process the clock rate of 2 GHz could already be recognized, under Windows 2000 it was shown with an Intel tool that is supposed to protect against overclocked CPUs that the CPU really runs at 2 GHz (5 x 400 MHz). This Pentium 4 is not yet based on the Northwood core, but is still based on the Willamette core. This means that Intel has found a way to produce a CPU with a structure width of 0.18 microns that can handle 2 GHz. So this time Intel could keep its promise to be able to deliver such CPUs already in the middle of this year, especially since the CPU ran stably in several 3DMark2001 demo runs.
