The Pentium 4 Bench Test 
Architecture and Performance Charting Of Intel's New Flagship

By Dave Altavilla - November 20, 2000

From the previous page's shots, you were probably wondering what sort of cooling the P4 requires.  Well, although we are not familiar with the specific standard that Intel will set, we can show you the setup that came in this system.

Coupled with a large high speed fan, this copper based unit really draws the heat out of the P4.  The unit that was installed in our system does look somewhat "prototype" like but never the less, it performs well.  This may or may not be the form factor of the official "retail" heat sink, once the P4 is shipping in high volume to the mass market in the retail channel.  Of course, there are many form factors of retail sinks today either way.

Point of Interest - ATX12V 
More power Scotty! We simply must have more power!

By now, you may have noticed that there are a few more connectors on the motherboard than perhaps you are use to seeing.  That is because the Intel D850GB Motherboard utilizes the new "ATX12V" specification to implement its power distribution.  There are two more power connectors in addition to the standard ATX connector for the motherboard.  The 12 Volt source connector has been added as well as something called the "Auxilary Power" connector.  This last connector looks like one half of an AT power connector.  Here is a mechanical drawing of the ATX12V connector specification.



In short, if you don't have one of these new power supplies in your system, with these additional connectors and outputs, you will have to upgrade your power supply as well, if you decide to move up to a Pentium 4.  Folks may not look too kindly on this but remember, we are talking about a platform change here.  In a way, it almost comes with the territory.  However, many of the recent products based on the ATX 2.03 spec, like the Enermax units sold at Outside Loop Computers,  in fact have the 12V and Aux connectors available as well as more than enough power to handle the job.


Since we're on the subject of power, let's hit the button.


Running with the 1.5GHz. Pentium 4
Some things change and some stay the same


The BIOS of the D850GB Motherboard is somewhat "plain vanilla" in comparison to some of the very sophisticated interfaces of P3 models from various manufacturers these days.  Regardless, there are two screens that were worth the trip into the setup.

A keen sense of the obvious will tell you that yes indeed we have powered up a Pentium 4 system at 1.5GHz.  However, only the most astute reader may notice that in the shot on the right, there is a section called "Intel Rapid Boot".  As the name suggests,  this feature allows the BIOS to skip memory tests and other system checks that delay boot up of the system.  With Rapid Boot enabled, the system boots significantly quicker than any Pentium 3 or Athlon system we have tested to date.
