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

By Dave Altavilla - November 20, 2000
 

Intel was kind enough to send us a complete Pentium 4 system for testing and evaluation.  This system included a Pentium 4 1.5GHz. Processor, 256MB of RAMBUS DRAM and the Intel D850GB i850 Motherboard, among other things.

RAMBUS, as of late has almost been a four letter word.  However, as it is well known, Intel has all but bet the farm on the support of this highly controversial memory subsystem.  This time around Intel is utilizing RAMBUS with 2X the bandwidth found on their i820 implementation.  The i850 chipset that supports the Pentium 4 also utilizes a Dual Channel RAMBUS DRAM architecture for 3.2GB/sec. of bandwidth.  That folks, is one fat pipe for data to the processor.

The specs on this board are pretty straight forward.  The i850 (the chip on the bottom left) runs a 400MHz "Quad Pumped" system bus to the processor.  It also generates a fair amount of heat and, as you can see above, a heat sink is installed to keep it cool.  In addition, Intel's ICH2 chip (on bottom right) otherwise known as the I/O Controller Hub, provides for the drive subsystem interface, PCI and CNR Slots, as well as the AC97 Audio, USB and every other peripheral that needs to talk to the system bus.  So, with the exception of the Dual Channel RAMBUS support, the rest of the features are standard equipment, as least as far as the untrained eye can see.  Allow us to dig deeper here and we'll show you a few things you may not see yet.
